Main article

FinanceFinance is often defined simply as the management of money or “funds” management. [1] Modern finance, however,is a family of business activity that includes the origination, marketing, and management of cash and moneysurrogates through a variety of capital accounts, instruments, and markets created for transacting and trading assets,liabilities, and risks. Finance is conceptualized, structured, and regulated by a complex system of power relationswithin political economies across state and global markets. Finance is both art (e.g. product development) andscience (e.g. measurement), although these activities increasingly converge through the intense technical andinstitutional focus on measuring and hedging risk-return relationships that underlie shareholder value. Networks offinancial businesses exist to create, negotiate, market, and trade in evermore-complex financial products and servicesfor their own as well as their clients’ accounts. Financial performance measures assess the efficiency and profitabilityof investments, the safety of debtors’ claims against assets, and the likelihood that derivative instruments will protectinvestors against a variety of market risks.The financial system consists of public and private interests and the markets that serve them. It provides capital fromindividual and institutional investors who transfer money directly and through intermediaries (e.g. banks, insurancecompanies, brokerage and fund management firms) to other individuals, firms, and governments that acquireresources and transact business. With the expectation of reaping profits, investors fund credit in the forms of (1) debtcapital (e.g. corporate and government notes and bonds, mortgage securities and other credit instruments), (2) equitycapital (e.g. listed and unlisted company shares), and (3) the derivative products of a wide variety of capitalinvestments including debt and equity securities, property, commodities, and insurance products. Although closelyrelated, the disciplines of economics and finance are distinctive. The “economy” is a social institution that organizesa society’s production, distribution, and consumption of goods and services,” all of which must be financed.Economists make a number of abstract assumptions for purposes of their analyses and predictions. They generallyregard financial markets that function for the financial system as an efficient mechanism. In practice, however,emerging research is demonstrating that such assumptions are unreliable. Instead, financial markets are subject tohuman error and emotion. [2] New research discloses the mischaracterization of investment safety and measures offinancial products and markets so complex that their effects, especially under conditions of uncertainty, areimpossible to predict. The study of finance is subsumed under economics as financial economics, but the scope,speed, power relations and practices of the financial system can uplift or cripple whole economies and the well-beingof households, businesses and governing bodies within them—sometimes in a single day.Three overarching divisions exist within the academic discipline of finance and its related practices: 1) personalfinance: the finances of individuals and families concerning household income and expenses, credit and debtmanagement, saving and investing, and income security in later life, 2) corporate finance: the finances of for-profitorganizations including corporations, trusts, partnerships and other entities, and 3) public finance: the financialaffairs of domestic and international governments and other public entities. [3] Areas of study within (and theinteractions among) these three levels affect all dimensions of social life: politics, taxes, art, religion, housing, healthcare, poverty and wealth, consumption, sports, transportation, labor force participation, media, and education. Whileeach has a vast accumulated literature of its own, the effects of macro and micro level financing that mold andimpact these and other domains of human and societal life typically have been treated by researchers as “policy,”“welfare,” “work,” “stratification,” and so forth, or have been largely unexplored. Recent research in "behavioralfinance" is promising, albeit a relative newcomer, to the existing body of financial research that focuses primarily onmeasurement.

Loans have become increasingly packaged for resale, meaning that an investor buys the loan (debt) from a bank ordirectly from a corporation. Bonds are debt instruments sold to investors for organizations such as companies,governments or charities.[4] The investor can then hold the debt and collect the interest or sell the debt on asecondary market. Banks are the main facilitators of funding through the provision of credit, although private equity,mutual funds, hedge funds, and other organizations have become important as they invest in various forms of debt.Financial assets, known as investments, are financially managed with careful attention to financial risk managementto control financial risk. Financial instruments allow many forms of securitized assets to be traded on securitiesexchanges such as stock exchanges, including debt such as bonds as well as equity in publicly traded corporations.Central banks, such as the Federal Reserve System banks in the United States and Bank of England in the UnitedKingdom, are strong players in public finance, acting as lenders of last resort as well as strong influences onmonetary and credit conditions in the economy.[5]

Overview of techniques and sectors of the financial industryAn entity whose income exceeds its expenditure can lend or invest the excess income. On the other hand, an entitywhose income is less than its expenditure can raise capital by borrowing or selling equity claims, decreasing itsexpenses, or increasing its income. The lender can find a borrower, a financial intermediary such as a bank, or buynotes or bonds in the bond market. The lender receives interest, the borrower pays a higher interest than the lenderreceives, and the financial intermediary earns the difference for arranging the loan.A bank aggregates the activities of many borrowers and lenders. A bank accepts deposits from lenders, on which itpays interest. The bank then lends these deposits to borrowers. Banks allow borrowers and lenders, of different sizes,to coordinate their activity.Finance is used by individuals (personal finance), by governments (public finance), by businesses (corporatefinance) and by a wide variety of other organizations, including schools and non-profit organizations. In general, thegoals of each of the above activities are achieved through the use of appropriate financial instruments andmethodologies, with consideration to their institutional setting.Finance is one of the most important aspects of business management and includes decisions related to the use andacquisition of funds for the enterprise.In corporate finance, a company's capital structure is the total mix of financing methods it uses to raise funds. Onemethod is debt financing, which includes bank loans and bond sales. Another method is equity financing - the sale ofstock by a company to investors, the original shareholders of a share. Ownership of a share gives the shareholdercertain contractual rights and powers, which typically include the right to receive declared dividends and to vote theproxy on important matters (e.g., board elections). The owners of both bonds and stock, may be institutionalinvestors - financial institutions such as investment banks and pension funds — or private individuals, called privateinvestors or retail investors.

Areas of finance

Personal financeQuestions in personal finance revolve around•• How much money will be needed by an individual (or by a family), and when?•• How can people protect themselves against unforeseen personal events, as well as those in the external economy?•• How can family assets best be transferred across generations (bequests and inheritance)?•• How does tax policy (tax subsidies or penalties) affect personal financial decisions?•• How does credit affect an individual's financial standing?•• How can one plan for a secure financial future in an environment of economic instability?Personal financial decisions may involve paying for education, financing durable goods such as real estate and cars,buying insurance, e.g. health and property insurance, investing and saving for retirement.Personal financial decisions may also involve paying for a loan, or debt obligations.

Corporate financeManagerial or corporate finance is the task of providing the funds for a corporation's activities (for small business,this is referred to as SME finance). Corporate finance generally involves balancing risk and profitability, whileattempting to maximize an entity's wealth and the value of its stock, and generically entails three interrelateddecisions. In the first, "the investment decision", management must decide which "projects" (if any) to undertake.The discipline of capital budgeting is devoted to this question, and may employ standard business valuationtechniques or even extend to real options valuation; see Financial modeling. The second, "the financing decision"relates to how these investments are to be funded: capital here is provided by shareholders, in the form of equity(privately or via an initial public offering), creditors, often in the form of bonds, and the firm's operations (cashflow). Short-term funding or working capital is mostly provided by banks extending a line of credit. The balancebetween these elements forms the company's capital structure. The third, "the dividend decision", requiresmanagement to determine whether any unappropriated profit is to be retained for future investment / operationalrequirements, or instead to be distributed to shareholders, and if so in what form. Short term financial management isoften termed "working capital management", and relates to cash-, inventory- and debtors management. These areasoften overlap with the firm's accounting function, however, financial accounting is more concerned with thereporting of historical financial information, while these financial decisions are directed toward the future of thefirm.

Finance of public entitiesPublic finance describes finance as related to sovereign states and sub-national entities (states/provinces, counties,municipalities, etc.) and related public entities (e.g. school districts) or agencies. It is concerned with:•• Identification of required expenditure of a public sector entity•• Source(s) of that entity's revenue•• The budgeting process• Debt issuance (municipal bonds) for public works projects

Financial risk managementFinancial risk management is the practice of creating and protecting economic value in a firm by using financialinstruments to manage exposure to risk, particularly credit risk and market risk. (Other risk types include Foreignexchange, Shape, Volatility, Sector, Liquidity, Inflation risks, etc.) It focuses on when and how to hedge usingfinancial instruments; in this sense it overlaps with financial engineering. Similar to general risk management,financial risk management requires identifying its sources, measuring it (see: Risk measure: Well known riskmeasures), and formulating plans to address these, and can be qualitative and quantitative. In the banking sectorworldwide, the Basel Accords are generally adopted by internationally active banks for tracking, reporting andexposing operational, credit and market risks.

Finance theory

Financial economicsFinancial economics is the branch of economics studying the interrelation of financial variables, such as prices,interest rates and shares, as opposed to those concerning the real economy. Financial economics concentrates oninfluences of real economic variables on financial ones, in contrast to pure finance. It centres on decision makingunder uncertainty in the context of the financial markets, and the resultant economic and financial models. Itessentially explores how rational investors would apply decision theory to the problem of investment. Here, the twinassumptions of rationality and market efficiency lead to modern portfolio theory (the CAPM), and to the BlackScholes theory for option valuation; it further studies phenomena and models where these assumptions do not hold,or are extended. "Financial economics", at least formally, also considers investment under "certainty" (Fisherseparation theorem, "theory of investment value", Modigliani-Miller theorem) and hence also contributes tocorporate finance theory. Financial Econometrics is the branch of Financial Economics that uses econometrictechniques to parameterize the relationships suggested.

Financial mathematicsFinancial mathematics is a field of applied mathematics, concerned with financial markets. The subject has a closerelationship with the discipline of financial economics, which is concerned with much of the underlying theory.Generally, mathematical finance will derive, and extend, the mathematical or numerical models suggested byfinancial economics. In terms of practice, mathematical finance also overlaps heavily with the field of computationalfinance (also known as financial engineering). Arguably, these are largely synonymous, although the latter focuseson application, while the former focuses on modeling and derivation (see: Quantitative analyst). The field is largelyfocused on the modelling of derivatives, although other important subfields include insurance mathematics andquantitative portfolio problems. See Outline of finance: Mathematical tools; Outline of finance: Derivatives pricing.

Experimental financeExperimental finance aims to establish different market settings and environments to observe experimentally andprovide a lens through which science can analyze agents' behavior and the resulting characteristics of trading flows,information diffusion and aggregation, price setting mechanisms, and returns processes. Researchers in experimentalfinance can study to what extent existing financial economics theory makes valid predictions, and attempt todiscover new principles on which such theory can be extended. Research may proceed by conducting tradingsimulations or by establishing and studying the behaviour of people in artificial competitive market-like settings.

Behavioral financeBehavioral Finance studies how the psychology of investors or managers affects financial decisions and markets.Behavioral finance has grown over the last few decades to become central to finance.Behavioral finance includes such topics as:1.1. Empirical studies that demonstrate significant deviations from classical theories.2.2. Models of how psychology affects trading and prices3.3. Forecasting based on these methods.4.4. Studies of experimental asset markets and use of models to forecast experiments.A strand of behavioral finance has been dubbed Quantitative Behavioral Finance, which uses mathematical andstatistical methodology to understand behavioral biases in conjunction with valuation. Some of this endeavor hasbeen led by Gunduz Caginalp (Professor of Mathematics and Editor of Journal of Behavioral Finance during2001-2004) and collaborators including Vernon Smith (2002 Nobel Laureate in Economics), David Porter, DonBalenovich, Vladimira Ilieva, Ahmet Duran). Studies by Jeff Madura, Ray Sturm and others have demonstratedsignificant behavioral effects in stocks and exchange traded funds. Among other topics, quantitative behavioralfinance studies behavioral effects together with the non-classical assumption of the finiteness of assets.

Intangible asset financeIntangible asset finance is the area of finance that deals with intangible assets such as patents, trademarks, goodwill,reputation, etc.

The main techniques and sectors of thefinancial industry

Financial servicesFinancial services are the economic services provided by the finance industry, which encompasses a broad range oforganizations that manage money, including credit unions, banks, credit card companies, insurance companies,consumer finance companies, stock brokerages, investment funds and some government sponsored enterprises. As of2004, the financial services industry represented 20% of the market capitalization of the S&P 500 in the UnitedStates.[1]

History of financial servicesThe term "financial services" became more prevalent in the United States partly as a result of theGramm-Leach-Bliley Act of the late 1990s, which enabled different types of companies operating in the U.S.financial services industry at that time to merge.[2] Companies usually have two distinct approaches to this new typeof business. One approach would be a bank which simply buys an insurance company or an investment bank, keepsthe original brands of the acquired firm, and adds the acquisition to its holding company simply to diversify itsearnings. Outside the U.S. (e.g., in Japan), non-financial services companies are permitted within the holdingcompany. In this scenario, each company still looks independent, and has its own customers, etc. In the other style, abank would simply create its own brokerage division or insurance division and attempt to sell those products to itsown existing customers, with incentives for combining all things with one company...

BanksA "commercial bank" is what is commonly referred to as simply a "bank". The term "commercial" is used todistinguish it from an "investment bank," a type of financial services entity which, instead of lending money directlyto a business, helps businesses raise money from other firms in the form of bonds (debt) or stock (equity).

Banking servicesThe primary operations of banks include:• Keeping money safe while also allowing withdrawals when needed• Issuance of checkbooks so that bills can be paid and other kinds of payments can be delivered by post• Provide personal loans, commercial loans, and mortgage loans (typically loans to purchase a home, property or

business)• Issuance of credit cards and processing of credit card transactions and billing• Issuance of debit cards for use as a substitute for checks• Allow financial transactions at branches or by using Automatic Teller Machines (ATMs)• Provide wire transfers of funds and Electronic fund transfers between banks• Facilitation of standing orders and direct debits, so payments for bills can be made automatically• Provide overdraft agreements for the temporary advancement of the Bank's own money to meet monthly spending

commitments of a customer in their current account.•• Provide internet banking system to facilitate the customers to view and operate their respective accounts through

internet.

Page 11: Wikipedia Book Finance

Financial services 8

•• Provide Charge card advances of the Bank's own money for customers wishing to settle credit advances monthly.• Provide a check guaranteed by the Bank itself and prepaid by the customer, such as a cashier's check or certified

check.• Notary service for financial and other documents•• Accepting the deposits from customer and provide the credit facilities to them.

Other types of bank services• Private banking - Private banks provide banking services exclusively to high net worth individuals. Many

financial services firms require a person or family to have a certain minimum net worth to qualify for privatebanking services.[3] Private banks often provide more personal services, such as wealth management and taxplanning, than normal retail banks.[4]

• Capital market bank - bank that underwrite debt and equity, assist company deals (advisory services, underwritingand advisory fees), and restructure debt into structured finance products.

• Bank cards - include both credit cards and debit cards. Bank Of America is the largest issuer of bank cards.•• Credit card machine services and networks - Companies which provide credit card machine and payment

networks call themselves "merchant card providers".

Foreign exchange servicesForeign exchange services are provided by many banks around the world. Foreign exchange services include:• Currency exchange - where clients can purchase and sell foreign currency banknotes.• Foreign Currency Banking - banking transactions are done in foreign currency.• Wire transfer - where clients can send funds to international banks abroad.

Investment services• Asset management - the term usually given to describe companies which run collective investment funds. Also

refers to services provided by others, generally registered with the Securities and Exchange Commission asRegistered Investment Advisors.

• Hedge fund management - Hedge funds often employ the services of "prime brokerage" divisions at majorinvestment banks to execute their trades.

• Custody services - the safe-keeping and processing of the world's securities trades and servicing the associatedportfolios. Assets under custody in the world are approximately $100 trillion.[5]

Insurance• Insurance brokerage - Insurance brokers shop for insurance (generally corporate property and casualty insurance)

on behalf of customers. Recently a number of websites have been created to give consumers basic pricecomparisons for services such as insurance, causing controversy within the industry.[6]

• Insurance underwriting - Personal lines insurance underwriters actually underwrite insurance for individuals, aservice still offered primarily through agents, insurance brokers, and stock brokers. Underwriters may also offersimilar commercial lines of coverage for businesses. Activities include insurance and annuities, life insurance,retirement insurance, health insurance, and property & casualty insurance.

• Reinsurance - Reinsurance is insurance sold to insurers themselves, to protect them from catastrophic losses.

Page 12: Wikipedia Book Finance

Financial services 9

Other financial services•• Intermediation or advisory services - These services involve stock brokers (private client services) and discount

brokers. Stock brokers assist investors in buying or selling shares. Primarily internet-based companies are oftenreferred to as discount brokerages, although many now have branch offices to assist clients. These brokeragesprimarily target individual investors. Full service and private client firms primarily assist and execute trades forclients with large amounts of capital to invest, such as large companies, wealthy individuals, and investmentmanagement funds.

• Private equity - Private equity funds are typically closed-end funds, which usually take controlling equity stakesin businesses that are either private, or taken private once acquired. Private equity funds often use leveragedbuyouts (LBOs) to acquire the firms in which they invest. The most successful private equity funds can generatereturns significantly higher than provided by the equity markets

• Venture capital is a type of private equity capital typically provided by professional, outside investors to new,high-potential-growth companies in the interest of taking the company to an IPO or trade sale of the business.

• Angel investment - An angel investor or angel (known as a business angel or informal investor in Europe), is anaffluent individual who provides capital for a business start-up, usually in exchange for convertible debt orownership equity. A small but increasing number of angel investors organize themselves into angel groups orangel networks to share research and pool their investment capital.

• Conglomerates - A financial services conglomerate is a financial services firm that is active in more than onesector of the financial services market e.g. life insurance, general insurance, health insurance, asset management,retail banking, wholesale banking, investment banking, etc. A key rationale for the existence of such businesses isthe existence of diversification benefits that are present when different types of businesses are aggregated i.e. badthings don't always happen at the same time. As a consequence, economic capital for a conglomerate is usuallysubstantially less than economic capital is for the sum of its parts.

• Debt resolution is a consumer service that assists individuals that have too much debt to pay off as requested, butdo not want to file bankruptcy and wish to pay off their debts owed. This debt can be accrued in various waysincluding but not limited to personal loans, credit cards or in some cases merchant accounts. There are manyservices/companies that can assist with this. These can include debt consolidation, debt settlement andrefinancing.

Financial crime

UKFraud within the financial industry costs the UK (regulated by the FSA) an estimated £14bn a year and it is believeda further £25bn is laundered by British institutions.[7]

Market shareThe financial services industry constitutes the largest group of companies in the world in terms of earnings andequity market capitalization. However it is not the largest category in terms of revenue or number of employees. It isalso a slow growing and extremely fragmented industry, with the largest company (Citigroup), only having a 3 % USmarket share.[8] In contrast, the largest home improvement store in the US, Home Depot, has a 30 % market share,and the largest coffee house Starbucks has a 32% market share.

Personal finance

Personal financePersonal finance is the application of the principles of finance to the monetary decisions of an individual or familyunit. It addresses the ways in which individuals or families obtain, budget, save, and spend monetary resources overtime, taking into account various financial risks and future life events. Components of personal finance mightinclude checking and savings accounts, credit cards and consumer loans, investments in the stock market, retirementplans, social security benefits, insurance policies, and income tax management.

Personal financial planningA key component of personal finance is financial planning, which is a dynamic process that requires regularmonitoring and reevaluation. In general, it has five steps:1. Assessment: One's personal financial situation can be assessed by compiling simplified versions of financial

balance sheets and income statements. A personal balance sheet lists the values of personal assets (e.g., car,house, clothes, stocks, bank account), along with personal liabilities (e.g., credit card debt, bank loan, mortgage).A personal income statement lists personal income and expenses.

2. Setting goals: Two examples are "1. Retire at age 65 with a personal net worth of $1,000,000," and, "2. Buy ahouse in 3 years while paying a monthly mortgage servicing cost that is no more than 25% of my gross income."Having multiple goals is common, including a mix of short term and long term goals. Setting financial goals helpsto direct financial planning. Goal setting is done with an objective to meet certain financial requirements.

3. Creating a plan: The financial plan details how to accomplish your goals. It could include, for example,reducing unnecessary expenses, increasing one's employment income, or investing in the stock market.

4. Execution: Execution of one's personal financial plan often requires discipline and perseverance. Many peopleobtain assistance from professionals such as accountants, financial planners, investment advisers, and lawyers.

5. Monitoring and reassessment: As time passes, one's personal financial plan must be monitored for possibleadjustments or reassessments.

Typical goals most adults and young adults have are paying off credit card and/or student loan debt, investing forretirement, investing for college costs for children, paying medical expenses, and planning for passing on theirproperty to their heirs (which is known as estate planning).The six key areas of personal financial planning, as suggested by the Financial Planning Standards Board, are [1]:1. Financial position: this area is concerned with understanding the personal resources available by examining net

worth and household cash flow. Net worth is a person's balance sheet, calculated by adding up all assets underthat person's control, minus all liabilities of the household, at one point in time. Household cash flow totals up allthe expected sources of income within a year, minus all expected expenses within the same year. From thisanalysis, the financial planner can determine to what degree and in what time the personal goals can beaccomplished.

2. Adequate protection: the analysis of how to protect a household from unforeseen risks. These risks can be divided into liability, property, death, disability, health and long term care. Some of these risks may be self-insurable, while most will require the purchase of an insurance contract. Determining how much insurance to get, at the most cost effective terms requires knowledge of the market for personal insurance. Business owners, professionals, athletes and entertainers require specialized insurance professionals to adequately protect themselves. Since insurance also enjoys some tax benefits, utilizing insurance investment products may be a

Page 15: Wikipedia Book Finance

Personal finance 12

critical piece of the overall investment planning.3. Tax planning: typically the income tax is the single largest expense in a household. Managing taxes is not a

question of if you will pay taxes, but when and how much. Government gives many incentives in the form of taxdeductions and credits, which can be used to reduce the lifetime tax burden. Most modern governments use aprogressive tax. Typically, as your income grows, you pay a higher marginal rate of tax. Understanding how totake advantage of the myriad tax breaks when planning your personal finances can make a significant impactupon your success.

4. Investment and Accumulation Goals: planning how to accumulate enough money to acquire items with a highprice is what most people consider to be financial planning. The major reasons to accumulate assets is for thefollowing:1.1. purchasing a house2.2. purchasing a car3.3. starting a business4.4. paying for education expenses5.5. accumulating money for retirement, to generate a stream of income to cover lifestyle expenses.

Achieving these goals requires projecting what they will cost, and when you need to withdraw funds. A majorrisk to the household in achieving their accumulation goal is the rate of price increases over time, or inflation.Using net present value calculators, the financial planner will suggest a combination of asset earmarking andregular savings to be invested in a variety of investments. In order to overcome the rate of inflation, theinvestment portfolio has to get a higher rate of return, which typically will subject the portfolio to a number ofrisks. Managing these portfolio risks is most often accomplished using asset allocation, which seeks todiversify investment risk and opportunity. This asset allocation will prescribe a percentage allocation to beinvested in stocks, bonds, cash and alternative investments. The allocation should also take into considerationthe personal risk profile of every investor, since risk attitudes vary from person to person.

5. Retirement Planning: retirement planning is the process of understanding how much it costs to live atretirement, and coming up with a plan to distribute assets to meet any income shortfall.

6. Estate Planning: involves planning for the disposition of your asset when you die. Typically, there is a tax due tothe state or federal government at your death. Avoiding these taxes means that more of your assets will bedistributed to your heirs. You can leave your assets to family, friends or charitable groups.

Corporate finance

Corporate financeCorporate finance is the area of finance dealing with monetary decisions that business enterprises make and thetools and analysis used to make these decisions. The primary goal of corporate finance is to maximize shareholdervalue.[1] Although it is in principle different from managerial finance which studies the financial decisions of allfirms, rather than corporations alone, the main concepts in the study of corporate finance are applicable to thefinancial problems of all kinds of firms.The discipline can be divided into long-term and short-term decisions and techniques. Capital investment decisionsare long-term choices about which projects receive investment, whether to finance that investment with equity ordebt, and when or whether to pay dividends to shareholders. On the other hand, short term decisions deal with theshort-term balance of current assets and current liabilities; the focus here is on managing cash, inventories, andshort-term borrowing and lending (such as the terms on credit extended to customers).The terms corporate finance and corporate financier are also associated with investment banking. The typical roleof an investment bank is to evaluate the company's financial needs and raise the appropriate type of capital that bestfits those needs. Thus, the terms “corporate finance” and “corporate financier” may be associated with transactions inwhich capital is raised in order to create, develop, grow or acquire businesses.

Capital investment decisionsCapital investment decisions[2] are long-term corporate finance decisions relating to fixed assets and capitalstructure. Decisions are based on several inter-related criteria. (1) Corporate management seeks to maximize thevalue of the firm by investing in projects which yield a positive net present value when valued using an appropriatediscount rate in consideration of risk. (2) These projects must also be financed appropriately. (3) If no suchopportunities exist, maximizing shareholder value dictates that management must return excess cash to shareholders(i.e., distribution via dividends). Capital investment decisions thus comprise an investment decision, a financingdecision, and a dividend decision.

The investment decisionManagement must allocate limited resources between competing opportunities (projects) in a process known ascapital budgeting.[3] Making this investment, or capital allocation, decision requires estimating the value of eachopportunity or project, which is a function of the size, timing and predictability of future cash flows.

Project valuation

Further information: Business valuation, stock valuation, and fundamental analysisIn general,[4] each project's value will be estimated using a discounted cash flow (DCF) valuation, and theopportunity with the highest value, as measured by the resultant net present value (NPV) will be selected (applied toCorporate Finance by Joel Dean in 1951; see also Fisher separation theorem, John Burr Williams#Theory). Thisrequires estimating the size and timing of all of the incremental cash flows resulting from the project. Such futurecash flows are then discounted to determine their present value (see Time value of money). These present values arethen summed, and this sum net of the initial investment outlay is the NPV. See Financial modeling.

The NPV is greatly affected by the discount rate. Thus, identifying the proper discount rate – often termed, theproject "hurdle rate"[5] – is critical to making an appropriate decision. The hurdle rate is the minimum acceptablereturn on an investment—i.e. the project appropriate discount rate. The hurdle rate should reflect the riskiness of theinvestment, typically measured by volatility of cash flows, and must take into account the project-relevant financingmix. Managers use models such as the CAPM or the APT to estimate a discount rate appropriate for a particularproject, and use the weighted average cost of capital (WACC) to reflect the financing mix selected. (A common errorin choosing a discount rate for a project is to apply a WACC that applies to the entire firm. Such an approach maynot be appropriate where the risk of a particular project differs markedly from that of the firm's existing portfolio ofassets.)In conjunction with NPV, there are several other measures used as (secondary) selection criteria in corporate finance.These are visible from the DCF and include discounted payback period, IRR, Modified IRR, equivalent annuity,capital efficiency, and ROI. Alternatives (complements) to NPV include MVA / EVA (Joel Stern, Stern Stewart &Co) and APV (Stewart Myers). See list of valuation topics.

Valuing flexibility

In many cases, for example R&D projects, a project may open (or close) various paths of action to the company, butthis reality will not (typically) be captured in a strict NPV approach.[6] Management will therefore (sometimes)employ tools which place an explicit value on these options. So, whereas in a DCF valuation the most likely oraverage or scenario specific cash flows are discounted, here the “flexible and staged nature” of the investment ismodelled, and hence "all" potential payoffs are considered. The difference between the two valuations is the "valueof flexibility" inherent in the project.The two most common tools are Decision Tree Analysis (DTA)[7][8] and Real options analysis (ROA);[9] they mayoften be used interchangeably:• DTA values flexibility by incorporating possible events (or states) and consequent management decisions. (For

example, a company would build a factory given that demand for its product exceeded a certain level during thepilot-phase, and outsource production otherwise. In turn, given further demand, it would similarly expand thefactory, and maintain it otherwise. In a DCF model, by contrast, there is no "branching" – each scenario must bemodelled separately.) In the decision tree, each management decision in response to an "event" generates a"branch" or "path" which the company could follow; the probabilities of each event are determined or specifiedby management. Once the tree is constructed: (1) "all" possible events and their resultant paths are visible tomanagement; (2) given this “knowledge” of the events that could follow, and assuming rational decision making,management chooses the actions corresponding to the highest value path probability weighted; (3) this path isthen taken as representative of project value. See Decision theory#Choice under uncertainty.

• ROA is usually used when the value of a project is contingent on the value of some other asset or underlyingvariable. (For example, the viability of a mining project is contingent on the price of gold; if the price is too low,management will abandon the mining rights, if sufficiently high, management will develop the ore body. Again, aDCF valuation would capture only one of these outcomes.) Here: (1) using financial option theory as aframework, the decision to be taken is identified as corresponding to either a call option or a put option; (2) anappropriate valuation technique is then employed – usually a variant on the Binomial options model or a bespokesimulation model, while Black Scholes type formulae are used less often; see Contingent claim valuation. (3) The"true" value of the project is then the NPV of the "most likely" scenario plus the option value. (Real options incorporate finance were first discussed by Stewart Myers in 1977; viewing corporate strategy as a series of optionswas originally per Timothy Luehrman, in the late 1990s.)

Quantifying uncertainty

Further information: Sensitivity analysis, Scenario planning, and Monte Carlo methods in financeGiven the uncertainty inherent in project forecasting and valuation,[8][10] analysts will wish to assess the sensitivityof project NPV to the various inputs (i.e. assumptions) to the DCF model. In a typical sensitivity analysis the analystwill vary one key factor while holding all other inputs constant, ceteris paribus. The sensitivity of NPV to a changein that factor is then observed, and is calculated as a "slope": ΔNPV / Δfactor. For example, the analyst willdetermine NPV at various growth rates in annual revenue as specified (usually at set increments, e.g. -10%, -5%,0%, 5%....), and then determine the sensitivity using this formula. Often, several variables may be of interest, andtheir various combinations produce a "value-surface",[11] (or even a "value-space",) where NPV is then a function ofseveral variables. See also Stress testing.Using a related technique, analysts also run scenario based forecasts of NPV. Here, a scenario comprises a particularoutcome for economy-wide, "global" factors (demand for the product, exchange rates, commodity prices, etc...) aswell as for company-specific factors (unit costs, etc...). As an example, the analyst may specify various revenuegrowth scenarios (e.g. 5% for "Worst Case", 10% for "Likely Case" and 25% for "Best Case"), where all key inputsare adjusted so as to be consistent with the growth assumptions, and calculate the NPV for each. Note that forscenario based analysis, the various combinations of inputs must be internally consistent (see discussion at Financialmodeling), whereas for the sensitivity approach these need not be so. An application of this methodology is todetermine an "unbiased" NPV, where management determines a (subjective) probability for each scenario – the NPVfor the project is then the probability-weighted average of the various scenarios.A further advancement is to construct stochastic[12] or probabilistic financial models – as opposed to the traditionalstatic and deterministic models as above.[10] For this purpose, the most common method is to use Monte Carlosimulation to analyze the project’s NPV. This method was introduced to finance by David B. Hertz in 1964, althoughit has only recently become common: today analysts are even able to run simulations in spreadsheet based DCFmodels, typically using a risk-analysis add-in, such as @Risk or Crystal Ball. Here, the cash flow components thatare (heavily) impacted by uncertainty are simulated, mathematically reflecting their "random characteristics". Incontrast to the scenario approach above, the simulation produces several thousand random but possible outcomes, ortrials, "covering all conceivable real world contingencies in proportion to their likelihood;" [13] see Monte CarloSimulation versus “What If” Scenarios. The output is then a histogram of project NPV, and the average NPV of thepotential investment – as well as its volatility and other sensitivities – is then observed. This histogram providesinformation not visible from the static DCF: for example, it allows for an estimate of the probability that a projecthas a net present value greater than zero (or any other value).Continuing the above example: instead of assigning three discrete values to revenue growth, and to the other relevantvariables, the analyst would assign an appropriate probability distribution to each variable (commonly triangular orbeta), and, where possible, specify the observed or supposed correlation between the variables. These distributionswould then be "sampled" repeatedly – incorporating this correlation – so as to generate several thousand random butpossible scenarios, with corresponding valuations, which are then used to generate the NPV histogram. The resultantstatistics (average NPV and standard deviation of NPV) will be a more accurate mirror of the project's "randomness"than the variance observed under the scenario based approach. These are often used as estimates of the underlying"spot price" and volatility for the real option valuation as above; see Real options valuation: Valuation inputs. Amore robust Monte Carlo model would include the possible occurrence of risk events (e.g., a credit crunch) that drivevariations in one or more of the DCF model inputs.

The financing decision

Domestic credit to private sector in 2005.

Achieving the goals of corporatefinance requires that any corporateinvestment be financedappropriately.[14] The sources offinancing are, generically, capitalself-generated by the firm and capitalfrom external funders, obtained byissuing new debt and equity (andhybrid- or convertible securities). Asabove, since both hurdle rate and cashflows (and hence the riskiness of thefirm) will be affected, the financing mix will impact the valuation of the firm (as well as the other long-termfinancial management decisions). There are two interrelated decisions here:

• Management must identify the "optimal mix" of financing—the capital structure that results in maximumvalue.[15] (See Balance sheet, WACC, Fisher separation theorem; but, see also the Modigliani-Miller theorem.)Financing a project through debt results in a liability or obligation that must be serviced, thus entailing cash flowimplications independent of the project's degree of success. Equity financing is less risky with respect to cashflow commitments, but results in a dilution of share ownership, control and earnings. The cost of equity is alsotypically higher than the cost of debt (see CAPM and WACC), and so equity financing may result in an increasedhurdle rate which may offset any reduction in cash flow risk.[16]

• Management must attempt to match the long-term financing mix to the assets being financed as closely aspossible, in terms of both timing and cash flows. Managing any potential asset liability mismatch or duration gapentails matching the assets and liabilities according to maturity pattern ("Cashflow matching") or duration("immunization"); managing this relationship in the short-term is a major function of working capitalmanagement, as discussed below. Other techniques, such as securitization, or hedging using interest rate- or creditderivatives, are also common. See Asset liability management; Treasury management; Credit risk; Interest raterisk.

One of the main theories of how firms make their financing decisions is the Pecking Order Theory (Stewart Myers),which suggests that firms avoid external financing while they have internal financing available and avoid new equityfinancing while they can engage in new debt financing at reasonably low interest rates. Another major theory is theTrade-Off Theory in which firms are assumed to trade-off the tax benefits of debt with the bankruptcy costs of debtwhen making their decisions. Capital structure substitution theory hypothesizes that management manipulates thecapital structure such that earnings per share (EPS) are maximized. An emerging area in finance theory isright-financing whereby investment banks and corporations can enhance investment return and company value overtime by determining the right investment objectives, policy framework, institutional structure, source of financing(debt or equity) and expenditure framework within a given economy and under given market conditions. One lasttheory about this decision is the Market timing hypothesis which states that firms look for the cheaper type offinancing regardless of their current levels of internal resources, debt and equity.

The dividend decisionWhether to issue dividends,[17] and what amount, is calculated mainly on the basis of the company's unappropriatedprofit and its earning prospects for the coming year. The amount is also often calculated based on expected free cashflows i.e. cash remaining after all business expenses, and capital investment needs have been met.If there are no NPV positive opportunities, i.e. projects where returns exceed the hurdle rate, then – finance theorysuggests – management must return excess cash to shareholders as dividends. This is the general case, however thereare exceptions. For example, shareholders of a "growth stock", expect that the company will, almost by definition,retain earnings so as to fund growth internally. In other cases, even though an opportunity is currently NPV negative,management may consider “investment flexibility” / potential payoffs and decide to retain cash flows; see above andReal options.Management must also decide on the form of the dividend distribution, generally as cash dividends or via a sharebuyback. Various factors may be taken into consideration: where shareholders must pay tax on dividends, firms mayelect to retain earnings or to perform a stock buyback, in both cases increasing the value of shares outstanding.Alternatively, some companies will pay "dividends" from stock rather than in cash; see Corporate action. Today, it isgenerally accepted that dividend policy is value neutral – i.e. the value of the firm would be the same, whether itissued cash dividends or repurchased its stock (see Modigliani-Miller theorem).

Working capital managementDecisions relating to working capital and short term financing are referred to as working capital management.[18]

These involve managing the relationship between a firm's short-term assets and its short-term liabilities. In generalthis is as follows: As above, the goal of Corporate Finance is the maximization of firm value. In the context of longterm, capital investment decisions, firm value is enhanced through appropriately selecting and funding NPV positiveinvestments. These investments, in turn, have implications in terms of cash flow and cost of capital. The goal ofWorking Capital (i.e. short term) management is therefore to ensure that the firm is able to operate, and that it hassufficient cash flow to service long term debt, and to satisfy both maturing short-term debt and upcoming operationalexpenses. In so doing, firm value is enhanced when, and if, the return on capital exceeds the cost of capital; SeeEconomic value added (EVA).

Decision criteriaWorking capital is the amount of capital which is readily available to an organization. That is, working capital is thedifference between resources in cash or readily convertible into cash (Current Assets), and cash requirements(Current Liabilities). As a result, the decisions relating to working capital are always current, i.e. short term,decisions. In addition to time horizon, working capital decisions differ from capital investment decisions in terms ofdiscounting and profitability considerations; they are also "reversible" to some extent. (Considerations as to Riskappetite and return targets remain identical, although some constraints – such as those imposed by loan covenants –may be more relevant here).Working capital management decisions are therefore not taken on the same basis as long term decisions, andworking capital management applies different criteria in decision making: the main considerations are (1) cash flow /liquidity and (2) profitability / return on capital (of which cash flow is probably the more important).• The most widely used measure of cash flow is the net operating cycle, or cash conversion cycle. This represents

the time difference between cash payment for raw materials and cash collection for sales. The cash conversioncycle indicates the firm's ability to convert its resources into cash. Because this number effectively corresponds tothe time that the firm's cash is tied up in operations and unavailable for other activities, management generallyaims at a low net count. (Another measure is gross operating cycle which is the same as net operating cycleexcept that it does not take into account the creditors deferral period.)

Corporate finance 18

• In this context, the most useful measure of profitability is Return on capital (ROC). The result is shown as apercentage, determined by dividing relevant income for the 12 months by capital employed; Return on equity(ROE) shows this result for the firm's shareholders. As above, firm value is enhanced when, and if, the return oncapital, exceeds the cost of capital. ROC measures are therefore useful as a management tool, in that they linkshort-term policy with long-term decision making.

Management of working capitalGuided by the above criteria, management will use a combination of policies and techniques for the management ofworking capital.[19] These policies aim at managing the current assets (generally cash and cash equivalents,inventories and debtors) and the short term financing, such that cash flows and returns are acceptable.• Cash management. Identify the cash balance which allows for the business to meet day to day expenses, but

reduces cash holding costs.• Inventory management. Identify the level of inventory which allows for uninterrupted production but reduces

the investment in raw materials – and minimizes reordering costs – and hence increases cash flow; see Supplychain management; Just In Time (JIT); Economic order quantity (EOQ); Economic production quantity (EPQ).

• Debtors management. There are two inter-related roles here: Identify the appropriate credit policy, i.e. creditterms which will attract customers, such that any impact on cash flows and the cash conversion cycle will beoffset by increased revenue and hence Return on Capital (or vice versa); see Discounts and allowances.Implement appropriate Credit scoring policies and techniques such that the risk of default on any new business isacceptable given these criteria.

• Short term financing. Identify the appropriate source of financing, given the cash conversion cycle: theinventory is ideally financed by credit granted by the supplier; however, it may be necessary to utilize a bank loan(or overdraft), or to "convert debtors to cash" through "factoring".

Relationship with other areas in finance

Investment bankingUse of the term “corporate finance” varies considerably across the world. In the United States it is used, as above, todescribe activities, decisions and techniques that deal with many aspects of a company’s finances and capital. In theUnited Kingdom and Commonwealth countries, the terms “corporate finance” and “corporate financier” tend to beassociated with investment banking – i.e. with transactions in which capital is raised for the corporation.[20] Thesemay include•• Raising seed, start-up, development or expansion capital•• Mergers, demergers, acquisitions or the sale of private companies•• Mergers, demergers and takeovers of public companies, including public-to-private deals• Management buy-out, buy-in or similar of companies, divisions or subsidiaries – typically backed by private

equity•• Equity issues by companies, including the flotation of companies on a recognised stock exchange in order to raise

capital for development and/or to restructure ownership•• Raising capital via the issue of other forms of equity, debt and related securities for the refinancing and

restructuring of businesses•• Financing joint ventures, project finance, infrastructure finance, public-private partnerships and privatisations•• Secondary equity issues, whether by means of private placing or further issues on a stock market, especially

where linked to one of the transactions listed above.•• Raising debt and restructuring debt, especially when linked to the types of transactions listed above

Financial risk managementSee also: Financial engineering; Financial risk; Default (finance); Credit risk; Interest rate risk; Liquidityrisk; Operational risk; Volatility risk; Settlement risk; Value at Risk.

Risk management [21] is the process of measuring risk and then developing and implementing strategies to manage("hedge") that risk. Financial risk management, typically, is focused on the impact on corporate value due to adversechanges in commodity prices, interest rates, foreign exchange rates and stock prices (market risk). It will also play animportant role in short term cash- and treasury management. It is common for large corporations to have riskmanagement teams; often these overlap with the internal audit function. While it is impractical for many small firmsto have formal risk management teams, many still apply risk management informally.The discipline typically focuses on risks that can be hedged using traded financial instruments; see Cash flow hedge,Foreign exchange hedge. Derivatives are often employed here. Because company specific, "over the counter" (OTC)contracts tend to be costly to create and monitor, derivatives that trade on well-established financial markets orexchanges are often preferred. These standard derivative instruments include options, futures contracts, forwardcontracts, and swaps; the "second generation" exotic derivatives usually trade OTC. Note that hedging-relatedtransactions will attract their own accounting treatment: see Hedge accounting, Mark-to-market accounting, FASB133, IAS 39.This area is related to corporate finance in two ways. Firstly, firm exposure to business and market risk is a directresult of previous Investment and Financing decisions. Secondly, both disciplines share the goal of enhancing, orpreserving, firm value. There is a fundamental debate relating to "Risk Management" and shareholder value: inquestion is the shareholder's desire to optimize risk versus taking exposure to pure risk (a risk event that only has anegative side, such as loss of life or limb). The debate links the value of risk management in a market to the cost ofbankruptcy in that market. See Fisher separation theorem.

Personal and public financeCorporate finance utilizes tools from almost all areas of finance. Some of the tools developed by and for corporationshave broad application to entities other than corporations, for example, to partnerships, sole proprietorships,not-for-profit organizations, governments, mutual funds, and personal wealth management. But in other cases theirapplication is very limited outside of the corporate finance arena. Because corporations deal in quantities of moneymuch greater than individuals, the analysis has developed into a discipline of its own. It can be differentiated frompersonal finance and public finance.

Alternate ApproachesA standard assumption in Corporate finance is that shareholders are the residual claimants and that the primary goalof executives should be to maximize shareholder value. Recently, however, legal scholars (e.g. Lynn Stout [22]) havequestioned this assumption, implying that the assumed goal of maximizing shareholder value is inappropriate for apublic corporation. This criticism in turn brings into question the advice of corporate finance, particularly related tostock buybacks made purportedly to "return value to shareholders," which is predicated on a legally erroneousassumption.

Financial capital can refer to money used by entrepreneurs andbusinesses to buy what they need to make their products or providetheir services or to that sector of the economy based on its operation,i.e. retail, corporate, investment banking, etc.

Three concepts of capital maintenanceauthorized in IFRS

Financial capital or just capital in finance and accounting, refers tothe funds provided by lenders (and investors) to businesses to purchasereal capital equipment for producing goods/services. Real Capital orEconomic Capital comprises physical goods that assist in theproduction of other goods and services, e.g. shovels for gravediggers,sewing machines for tailors, or machinery and tooling for factories.

Financial capital generally refers to saved-up financial wealth, especially that used to start or maintain a business. Afinancial concept of capital is adopted by most entities in preparing their financial reports. Under a financial conceptof capital, such as invested money or invested purchasing power, capital is synonymous with the net assets or equityof the entity. Under a physical concept of capital, such as operating capability, capital is regarded as the productivecapacity of the entity based on, for example, units of output per day.[1] Financial capital maintenance can bemeasured in either nominal monetary units or units of constant purchasing power.[2][3] There are thus three conceptsof capital maintenance in terms of International Financial Reporting Standards (IFRS): (1) Physical capitalmaintenance (2) Financial capital maintenance in nominal monetary units (3) Financial capital maintenance in unitsof constant purchasing power.[4][5]

Financial capital is provided by lenders for a price: interest. Also see time value of money for a more detaileddescription of how financial capital may be analyzed.Furthermore, financial capital, is any liquid medium or mechanism that represents wealth, or other styles of capital.It is, however, usually purchasing power in the form of money available for the production or purchasing of goods,etcetera. Capital can also be obtained by producing more than what is immediately required and saving the surplus.Financial capital has been subcategorized by some academics as economic or "productive capital" necessary foroperations, signaling capital which signals a company's financial strength to shareholders, and regulatory capitalwhich fulfills capital requirements.[6]

Differences between shares and debentures•• Shareholders are effectively owners; debenture-holders are creditors.•• Shareholders may vote at AGMs and be elected as directors; debenture-holders may not vote at AGMs or be

elected as directors.•• Shareholders receive profit in the form of dividends; debenture-holders receive a fixed rate of interest.•• If there is no profit, the shareholder does not receive a dividend; interest is paid to debenture-holders regardless of

whether or not a profit has been made.•• In case of dissolution of firms debenture holders are paid first as compared to shareholder.

InstrumentsA contract regarding any combination of capital assets is called a financial instrument, and may serve as a• medium of exchange,• standard of deferred payment,• unit of account, or• store of value.Most indigenous forms of money (wampum, shells, tally sticks and such) and the modern fiat money is only a"symbolic" storage of value and not a real storage of value like commodity money.

Own and borrowed capitalCapital contributed by the owner or entrepreneur of a business, and obtained, for example, by means of savings orinheritance, is known as own capital or equity, whereas that which is granted by another person or institution iscalled borrowed capital, and this must usually be paid back with interest. The ratio between debt and equity is namedleverage. It has to be optimized as a high leverage can bring a higher profit but create solvency risk.

Borrowed capitalThis is capital which the business borrows from institutions or people, and includes debentures:• Redeemable debentures•• Irredeemable debentures•• Debentures to bearer• Ordinary debentures•• bonds•• deposits•• loans

Own capitalThis is capital that owners of a business (shareholders and partners, for example) provide:•• Preference shares/hybrid source of finance

•• Ordinary preference shares•• Cumulative preference shares•• Participating preference shares

•• Ordinary shares•• Bonus shares•• Founders' sharesThese have preference over the equity shares. This means the payments made to the shareholders are first paid to thepreference shareholder(s) and then to the equity shareholders.

Issuing and tradingLike money, financial instruments may be "backed" by state military fiat, credit (i.e. social capital held by banks andtheir depositors), or commodity resources. Governments generally closely control the supply of it and usually requiresome "reserve" be held by institutions granting credit. Trading between various national currency instruments isconducted on a money market. Such trading reveals differences in probability of debt collection or store of valuefunction of that currency, as assigned by traders.

Financial capital 25

When in forms other than money, financial capital may be traded on bond markets or reinsurance markets withvarying degrees of trust in the social capital (not just credits) of bond-issuers, insurers, and others who issue andtrade in financial instruments. When payment is deferred on any such instrument, typically an interest rate is higherthan the standard interest rates paid by banks, or charged by the central bank on its money. Often such instrumentsare called fixed-income instruments if they have reliable payment schedules associated with the uniform rate ofinterest. A variable-rate instrument, such as many consumer mortgages, will reflect the standard rate for deferredpayment set by the central bank prime rate, increasing it by some fixed percentage. Other instruments, such as citizenentitlements, e.g. "U.S. Social Security", or other pensions, may be indexed to the rate of inflation, to provide areliable value stream.Trading in stock markets or commodity markets is actually trade in underlying assets which are not wholly financialin themselves, although they often move up and down in value in direct response to the trading in more purelyfinancial derivatives. Typically commodity markets depend on politics that affect international trade, e.g. boycottsand embargoes, or factors that influence natural capital, e.g. weather that affects food crops. Meanwhile, stockmarkets are more influenced by trust in corporate leaders, i.e. individual capital, by consumers, i.e. social capital or"brand capital" (in some analyses), and internal organizational efficiency, i.e. instructional capital and infrastructuralcapital. Some enterprises issue instruments to specifically track one limited division or brand. "Financial futures","Short selling" and "financial options" apply to these markets, and are typically pure financial bets on outcomes,rather than being a direct representation of any underlying asset.

Broadening the notionThe relationship between financial capital, money, and all other styles of capital, especially human capital or labor, isassumed in central bank policy and regulations regarding instruments as above.Such relationships and policies are characterized by a political economy - feudalist, socialist, capitalist, green,anarchist or otherwise. In effect, the means of money supply and other regulations on financial capital represent theeconomic sense of the value system of the society itself, as they determine the allocation of labor in that society.So, for instance, rules for increasing or reducing the money supply based on perceived inflation, or on measuringwell-being, reflect some such values, reflect the importance of using (all forms of) financial capital as a stable storeof value. If this is very important, inflation control is key - any amount of money inflation reduces the value offinancial capital with respect to all other types.If, however, the medium of exchange function is more critical, new money may be more freely issued regardless ofimpact on either inflation or well-being.

Marxian perspectivesIt is common in Marxist theory to refer to the role of "Finance Capital" as the determining and ruling class interest incapitalist society, particularly in the latter stages.[7][8]

ValuationNormally, a financial instrument is priced accordingly to the perception by capital market players of its expectedreturn and risk.Unit of account functions may come into question if valuations of complex financial instruments vary drasticallybased on timing. The "book value", "mark-to-market" and "mark-to-future"[9] conventions are three differentapproaches to reconciling financial capital value units of account.

Financial capital 26

Economic roleSocialism, capitalism, feudalism, anarchism, other civic theories take markedly different views of the role offinancial capital in social life, and propose various political restrictions to deal with that.Finance capitalism is the production of profit from the manipulation of financial capital. It is held in contrast toindustrial capitalism, where profit is made from the manufacture of goods.

Cornering the market 27

Cornering the marketIn finance, to corner the market is to get sufficient control of a particular stock, commodity, or other asset to allowthe price to be manipulated. Another definition: "To have the greatest market share in a particular industry withouthaving a monopoly. Companies that have cornered their markets usually have greater leeway in their decisions; forexample, they may charge higher prices for their products without fear of losing too much business. Largecompanies, such as Wal-Mart or Microsoft, are considered to have cornered their markets." [1] In either case, thecornerer hopes to gain control of enough of the supply of the commodity to be able to set the price for it.This can be done through several mechanisms. The most direct strategy is to simply buy up a large percentage of theavailable commodity offered for sale in some spot market and hoard it. With the advent of futures trading, a cornerermay buy a large number of futures contracts on a commodity and then sell them at a profit after inflating the price.Although there have been many attempts to corner markets by massive purchases in everything from tin to cattle, todate very few of these attempts have ever succeeded; instead, most of these attempted corners have tended to breakthemselves spontaneously. Indeed, as long ago as 1923, Edwin Lefèvre wrote, "very few of the great corners wereprofitable to the engineers of them."[2] A cornerer can become vulnerable due to the size of the position, especially ifthe attempt becomes widely known. If the rest of the market senses weakness, it may resist any attempt to artificiallydrive the market any further by actively taking opposing positions. If the price starts to move against the cornerer,any attempt by the cornerer to sell would likely cause the price to drop substantially. In such a situation, many otherparties could profit from the cornerer's need to unwind the position.More success in cornering the market has come by gaining a near-monopoly share in industries such as computers(like IBM) and software (like Microsoft).

Historical examples

ca 6th Century BCE: Thales of MiletusAccording to Aristotle in The Politics (Book I Section 1259a),[3] Thales of Miletus once cornered the market inolive-oil presses:

Thales, so the story goes, because of his poverty was taunted with the uselessness of philosophy; butfrom his knowledge of astronomy he had observed while it was still winter that there was going to be alarge crop of olives, so he raised a small sum of money and paid round deposits for the whole of theolive-presses in Miletus and Chios, which he hired at a low rent as nobody was running him up; andwhen the season arrived, there was a sudden demand for a number of presses at the same time, and byletting them out on what terms he liked he realized a large sum of money, so proving that it is easy forphilosophers to be rich if they choose.

19th century: Classic examples by Edwin LefèvreJournalist Edwin Lefèvre lists several examples of corners from the mid-19th century. He distinguishes corners asthe result of manipulations from corners as the result of competitive buying.

Cornelius Vanderbilt and the Harlem Railroad

One of the few cornerers whose rationale was published and justified, Cornelius Vanderbilt started accumulatingshares of the Harlem Railroad in 1862 because he anticipated its strategic value. He took control of the HarlemRailroad and later explained that he wanted to show that he could take this railroad, which was generally consideredworthless, and make it valuable. The corner of June 25, 1863 can be seen as just an episode in a strategic investmentthat served the public well.

James Fisk, Jay Gould and the Black Friday (1869)

The 1869 Black Friday financial panic in the United States was caused by the efforts of Jay Gould and James Fisk tocorner the gold market on the New York Gold Exchange. It was one of several scandals that rocked the presidency ofUlysses S. Grant. When the government gold hit the market, the premium plummeted within minutes and manyinvestors were ruined. Fisk and Gould escaped significant financial harm.

Lefèvre thoughts on corners of the old days

In chapter 19 of his book, Edwin Lefèvre tries to summarize the rationale for the corners of the 19th century.

“A wise old broker told me that all the big operators of the 60s and 70s had one ambition, and that was to work a corner. In many cases this wasthe offspring of vanity; in others, of the desire for revenge. [..] It was more than the prospective money profit that prompted the engineers ofcorners to do their damnedest. It was the vanity complex asserting itself among cold-bloodest operators. ”

20th century: The Northern Pacific RailwayThe corner of The Northern Pacific Railway on May 9, 1901, is a well documented case of competitive buying,resulting in a panic. The 2009 Annotated Edition of Reminiscences of a Stock Operator contains Lefèvre's originalaccount in chapter 3 as well as modern annotations explaining the actual locations and personalities on the pagemargins.

1920s: The Stutz Motor CompanyCalled "a forerunner of the Livermore and Cutten operations of a few years later" by historian Robert Sobel, theMarch 1920 corner of The Stutz Motor Company is an example of a manipulated corner ruining everyone involved,especially its originator Thomas Fortune Ryan.

1950s: The onion marketIn the late 1950s, United States onion farmers alleged that Sam Seigel and Vincent Kosuga, Chicago MercantileExchange traders, were attempting to corner the market on onions. Their complaints resulted in the passage of theOnion Futures Act, which banned trading in onion futures in the United States and remains in effect as of 2011.

1970s: The Hunt brothers and the silver marketBrothers Nelson Bunker Hunt and William Herbert Hunt attempted to corner the world silver markets in the late1970s and early 1980s, at one stage holding the rights to more than half of the world's deliverable silver.[4] Duringthe Hunts' accumulation of the precious metal, silver prices rose from $11 an ounce in September 1979 to nearly $50an ounce in January 1980.[5] Silver prices ultimately collapsed to below $11 an ounce two months later,[5] much ofthe fall occurring on a single day now known as Silver Thursday, due to changes made to exchange rules regardingthe purchase of commodities on margin.[6]

1990s: Hamanaka and the copper marketRogue trader Yasuo Hamanaka, Sumitomo Corporation's chief copper trader, attempted to corner the internationalcopper market over a ten year period leading up to 1996.[7] At one point during this "Sumitomo copper affair,"Hamanaka is believed to have controlled approximately 5% of the world copper market.[7] As his scheme collapsed,Sumitomo was left with large positions in the copper market, ultimately losing US$2.6 billion.[8] In 1997 Hamanakapleaded guilty to criminal charges stemming from his trading activity and was sentenced to an eight year prisonsentence.[8]

2008: Porsche and shares in VolkswagenDuring the financial crisis of 2007-2010 Porsche cornered the market in shares of Volkswagen, which briefly sawVolkswagen become the world's most valuable company.[9] Porsche claimed that its actions were intended to gaincontrol of Volkswagen rather than to manipulate the market: in this case, while cornering the market in Volkswagenshares, Porsche contracted with naked shorts—enabling it to perform a short squeeze on them.[10] It was ultimatelyunsuccessful, leading to the resignation of Porsche's chief executive and financial director and to the merger ofPorsche into Volkswagen.[11]

One of the wealthiest men in Germany's industry committed suicide after shorting Volkswagen shares.[12]

2010: Armajaro and the European cocoa marketOn July 17, 2010, Armajaro purchased 240,100 tonnes of cocoa.[13] The buyout caused cocoa prices to rise to theirhighest level since 1977. The purchase was valued at £658 million and accounted for 7 per cent of annual globalcocoa production.[14] The transaction, the largest single cocoa trade in 14 years, was carried out by ArmajaroHoldings, a hedge fund co-founded by Mr Anthony Ward. Ward, the manager of the hedge fund, has been dubbed"Chocfinger" by fellow traders for his exploits. The nickname is a reference to both the Bond villain Goldfinger aswell as a British confection.[15]

This example demonstrates that 7 per cent of a perishable good is enough to allow profit taking via cornering amarket.

2011: Oil and hedge fundsAll of the above examples had effects that were limited to niche markets. This opens up the question about thepossibility of cornering one of the markets for strategic commodities that are fundamental to all economies aroundthe world. In Summer 2011 Jim Cramer drew the public's attention to a corner of the oil market [16].

the cartel of nonconsumers who are using oil futures as part of an investing strategy that includesendless attempts to corner the market for crudes in order to make fortunes for them. that's what they didin 2008 when they cornered it and took it to $147. we know the futures markets are thin for oil. almostall the execs on the show confirm to me these futures are unreliable and easily manipulated. the pricecan be the benchmark for real commerce, meaning they can make a lot of money so long as no one seeksto bust the cartel price.

While Cramer points out frankly that this is a corner (calling into question the proper working of the free market),official sources avoid calling this situation a corner. For example, the U.S. Department of Energy explained it wouldrelease million barrels of oil from the Strategic Petroleum Reserve and called this

a warning shot to speculators in the oil market"Obama's SPR oil release confounds analysts" [17]. Yahoo. 2011-06-24..Since this corner is not yet over, it has to be evaluated later if this is a global corner showing how a corner can harmthe public interest.

Fictional examplesAn attempt to corner the market on orange juice futures plays a key role in the 1983 movie Trading Places. The twoprotagonists (played by Eddie Murphy and Dan Aykroyd) eventually foil their rivals' plan by short-selling thefutures, causing hundreds of millions of dollars in losses for the latter.

Insurance 31

InsuranceInsurance is a form of risk management primarily used to hedge against the risk of a contingent, uncertain loss.Insurance is defined as the equitable transfer of the risk of a loss, from one entity to another, in exchange forpayment. An insurer is a company selling the insurance; the insured, or policyholder, is the person or entity buyingthe insurance policy. The amount to be charged for a certain amount of insurance coverage is called the premium.Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study andpractice.The transaction involves the insured assuming a guaranteed and known relatively small loss in the form of paymentto the insurer in exchange for the insurer's promise to compensate (indemnify) the insured in the case of a financial(personal) loss. The insured receives a contract, called the insurance policy, which details the conditions andcircumstances under which the insured will be financially compensated.

PrinciplesInsurance involves pooling funds from many insured entities (known as exposures) to pay for the losses that somemay incur. The insured entities are therefore protected from risk for a fee, with the fee being dependent upon thefrequency and severity of the event occurring. In order to be insurable, the risk insured against must meet certaincharacteristics in order to be an insurable risk. Insurance is a commercial enterprise and a major part of the financialservices industry, but individual entities can also self-insure through saving money for possible future losses.[1]

InsurabilityRisk which can be insured by private companies typically share seven common characteristics:[2]

1. Large number of similar exposure units: Since insurance operates through pooling resources, the majority ofinsurance policies are provided for individual members of large classes, allowing insurers to benefit from the lawof large numbers in which predicted losses are similar to the actual losses. Exceptions include Lloyd's of London,which is famous for insuring the life or health of actors, sports figures and other famous individuals. However, allexposures will have particular differences, which may lead to different premium rates.

2. Definite loss: The loss takes place at a known time, in a known place, and from a known cause. The classicexample is death of an insured person on a life insurance policy. Fire, automobile accidents, and worker injuriesmay all easily meet this criterion. Other types of losses may only be definite in theory. Occupational disease, forinstance, may involve prolonged exposure to injurious conditions where no specific time, place or cause isidentifiable. Ideally, the time, place and cause of a loss should be clear enough that a reasonable person, withsufficient information, could objectively verify all three elements.

3. Accidental loss: The event that constitutes the trigger of a claim should be fortuitous, or at least outside thecontrol of the beneficiary of the insurance. The loss should be pure, in the sense that it results from an event forwhich there is only the opportunity for cost. Events that contain speculative elements, such as ordinary businessrisks or even purchasing a lottery ticket, are generally not considered insurable.

4. Large loss: The size of the loss must be meaningful from the perspective of the insured. Insurance premiumsneed to cover both the expected cost of losses, plus the cost of issuing and administering the policy, adjustinglosses, and supplying the capital needed to reasonably assure that the insurer will be able to pay claims. For smalllosses these latter costs may be several times the size of the expected cost of losses. There is hardly any point inpaying such costs unless the protection offered has real value to a buyer.

5. Affordable premium: If the likelihood of an insured event is so high, or the cost of the event so large, that the resulting premium is large relative to the amount of protection offered, it is not likely that the insurance will be purchased, even if on offer. Further, as the accounting profession formally recognizes in financial accounting

Page 35: Wikipedia Book Finance

Insurance 32

standards, the premium cannot be so large that there is not a reasonable chance of a significant loss to the insurer.If there is no such chance of loss, the transaction may have the form of insurance, but not the substance. (See theUS Financial Accounting Standards Board standard number 113)

6. Calculable loss: There are two elements that must be at least estimable, if not formally calculable: the probabilityof loss, and the attendant cost. Probability of loss is generally an empirical exercise, while cost has more to dowith the ability of a reasonable person in possession of a copy of the insurance policy and a proof of lossassociated with a claim presented under that policy to make a reasonably definite and objective evaluation of theamount of the loss recoverable as a result of the claim.

7. Limited risk of catastrophically large losses: Insurable losses are ideally independent and non-catastrophic,meaning that the losses do not happen all at once and individual losses are not severe enough to bankrupt theinsurer; insurers may prefer to limit their exposure to a loss from a single event to some small portion of theircapital base. Capital constrains insurers' ability to sell earthquake insurance as well as wind insurance in hurricanezones. In the US, flood risk is insured by the federal government. In commercial fire insurance it is possible tofind single properties whose total exposed value is well in excess of any individual insurer's capital constraint.Such properties are generally shared among several insurers, or are insured by a single insurer who syndicates therisk into the reinsurance market.

LegalWhen a company insures an individual entity, there are basic legal requirements. Several commonly cited legalprinciples of insurance include:[3]

1. Indemnity – the insurance company indemnifies, or compensates, the insured in the case of certain losses only upto the insured's interest.

2. Insurable interest – the insured typically must directly suffer from the loss. Insurable interest must exist whetherproperty insurance or insurance on a person is involved. The concept requires that the insured have a "stake" inthe loss or damage to the life or property insured. What that "stake" is will be determined by the kind of insuranceinvolved and the nature of the property ownership or relationship between the persons.

3. Utmost good faith – the insured and the insurer are bound by a good faith bond of honesty and fairness. Materialfacts must be disclosed.

4. Contribution – insurers which have similar obligations to the insured contribute in the indemnification, accordingto some method.

5. Subrogation – the insurance company acquires legal rights to pursue recoveries on behalf of the insured; forexample, the insurer may sue those liable for insured's loss.

6. Causa proxima, or proximate cause – the cause of loss (the peril) must be covered under the insuring agreementof the policy, and the dominant cause must not be excluded

7.7. Mitigation - In case of any loss or casualty, the asset owner must attempt to keep the loss to a minimum, as if theasset was not insured.

Page 36: Wikipedia Book Finance

Insurance 33

IndemnificationTo "indemnify" means to make whole again, or to be reinstated to the position that one was in, to the extent possible,prior to the happening of a specified event or peril. Accordingly, life insurance is generally not considered to beindemnity insurance, but rather "contingent" insurance (i.e., a claim arises on the occurrence of a specified event).There are generally two types of insurance contracts that seek to indemnify an insured:1.1. an "indemnity" policy, and2. a "pay on behalf" or "on behalf of"[4] policy.The difference is significant on paper, but rarely material in practice.An "indemnity" policy will never pay claims until the insured has paid out of pocket to some third party; forexample, a visitor to your home slips on a floor that you left wet and sues you for $10,000 and wins. Under an"indemnity" policy the homeowner would have to come up with the $10,000 to pay for the visitor's fall and thenwould be "indemnified" by the insurance carrier for the out of pocket costs (the $10,000).[4][5]

Under the same situation, a "pay on behalf" policy, the insurance carrier would pay the claim and the insured (thehomeowner in the above example) would not be out of pocket for anything. Most modern liability insurance iswritten on the basis of "pay on behalf" language.[4]

An entity seeking to transfer risk (an individual, corporation, or association of any type, etc.) becomes the 'insured'party once risk is assumed by an 'insurer', the insuring party, by means of a contract, called an insurance policy.Generally, an insurance contract includes, at a minimum, the following elements: identification of participatingparties (the insurer, the insured, the beneficiaries), the premium, the period of coverage, the particular loss eventcovered, the amount of coverage (i.e., the amount to be paid to the insured or beneficiary in the event of a loss), andexclusions (events not covered). An insured is thus said to be "indemnified" against the loss covered in the policy.When insured parties experience a loss for a specified peril, the coverage entitles the policyholder to make a claimagainst the insurer for the covered amount of loss as specified by the policy. The fee paid by the insured to theinsurer for assuming the risk is called the premium. Insurance premiums from many insureds are used to fundaccounts reserved for later payment of claims — in theory for a relatively few claimants — and for overhead costs.So long as an insurer maintains adequate funds set aside for anticipated losses (called reserves), the remainingmargin is an insurer's profit.

EffectsInsurance can have various effects on society through the way that it changes who bears the cost of losses anddamage. On one hand it can increase fraud, on the other it can help societies and individuals prepare for catastrophesand mitigate the effects of catastrophes on both households and societies.Insurance can influence the probability of losses through moral hazard, insurance fraud, and preventive steps by theinsurance company. Insurance scholars have typically used morale hazard to refer to the increased loss due tounintentional carelessness and moral hazard to refer to increased risk due to intentional carelessness orindifference.[6] Insurers attempt to address carelessness through inspections, policy provisions requiring certain typesof maintenance, and possible discounts for loss mitigation efforts. While in theory insurers could encourageinvestment in loss reduction, some commentators have argued that in practice insurers had historically notaggressively pursued loss control measures - particularly to prevent disaster losses such as hurricanes - because ofconcerns over rate reductions and legal battles. However, since about 1996 insurers began to take a more active rolein loss mitigation, such as through building codes.[7]

Insurers' business model

Underwriting and investingThe business model is to collect more in premium and investment income than is paid out in losses, and to also offera competitive price which consumers will accept. Profit can be reduced to a simple equation: Profit = earnedpremium + investment income - incurred loss - underwriting expenses.Insurers make money in two ways:1. Through underwriting, the process by which insurers select the risks to insure and decide how much in premiums

to charge for accepting those risks;2. By investing the premiums they collect from insured parties.The most complicated aspect of the insurance business is the actuarial science of ratemaking (price-setting) ofpolicies, which uses statistics and probability to approximate the rate of future claims based on a given risk. Afterproducing rates, the insurer will use discretion to reject or accept risks through the underwriting process.At the most basic level, initial ratemaking involves looking at the frequency and severity of insured perils and theexpected average payout resulting from these perils. Thereafter an insurance company will collect historical lossdata, bring the loss data to present value, and compare these prior losses to the premium collected in order to assessrate adequacy.[8] Loss ratios and expense loads are also used. Rating for different risk characteristics involves at themost basic level comparing the losses with "loss relativities" - a policy with twice as many losses would therefore becharged twice as much. More complex multivariate analyses are sometimes used when multiple characteristics areinvolved and a univariate analysis could produce confounded results. Other statistical methods may be used inassessing the probability of future losses.Upon termination of a given policy, the amount of premium collected and the investment gains thereon, minus theamount paid out in claims, is the insurer's underwriting profit on that policy. Underwriting performance is measuredby something called the "combined ratio"[9] which is the ratio of expenses/losses to premiums. A combined ratio ofless than 100 percent indicates an underwriting profit, while anything over 100 indicates an underwriting loss. Acompany with a combined ratio over 100% may nevertheless remain profitable due to investment earnings.Insurance companies earn investment profits on "float". Float, or available reserve, is the amount of money on handat any given moment that an insurer has collected in insurance premiums but has not paid out in claims. Insurers startinvesting insurance premiums as soon as they are collected and continue to earn interest or other income on themuntil claims are paid out. The Association of British Insurers (gathering 400 insurance companies and 94% of UKinsurance services) has almost 20% of the investments in the London Stock Exchange.[10]

In the United States, the underwriting loss of property and casualty insurance companies was $142.3 billion in thefive years ending 2003. But overall profit for the same period was $68.4 billion, as the result of float. Someinsurance industry insiders, most notably Hank Greenberg, do not believe that it is forever possible to sustain a profitfrom float without an underwriting profit as well, but this opinion is not universally held.Naturally, the float method is difficult to carry out in an economically depressed period. Bear markets do causeinsurers to shift away from investments and to toughen up their underwriting standards, so a poor economy generallymeans high insurance premiums. This tendency to swing between profitable and unprofitable periods over time iscommonly known as the underwriting, or insurance, cycle.[11]

ClaimsClaims and loss handling is the materialized utility of insurance; it is the actual "product" paid for. Claims may befiled by insureds directly with the insurer or through brokers or agents. The insurer may require that the claim befiled on its own proprietary forms, or may accept claims on a standard industry form, such as those produced byACORD.Insurance company claims departments employ a large number of claims adjusters supported by a staff of recordsmanagement and data entry clerks. Incoming claims are classified based on severity and are assigned to adjusterswhose settlement authority varies with their knowledge and experience. The adjuster undertakes an investigation ofeach claim, usually in close cooperation with the insured, determines if coverage is available under the terms of theinsurance contract, and if so, the reasonable monetary value of the claim, and authorizes payment.The policyholder may hire their own public adjuster to negotiate the settlement with the insurance company on theirbehalf. For policies that are complicated, where claims may be complex, the insured may take out a separateinsurance policy add on, called loss recovery insurance, which covers the cost of a public adjuster in the case of aclaim.Adjusting liability insurance claims is particularly difficult because there is a third party involved, the plaintiff, whois under no contractual obligation to cooperate with the insurer and may in fact regard the insurer as a deep pocket.The adjuster must obtain legal counsel for the insured (either inside "house" counsel or outside "panel" counsel),monitor litigation that may take years to complete, and appear in person or over the telephone with settlementauthority at a mandatory settlement conference when requested by the judge.If a claims adjuster suspects under-insurance, the condition of average may come into play to limit the insurancecompany's exposure.In managing the claims handling function, insurers seek to balance the elements of customer satisfaction,administrative handling expenses, and claims overpayment leakages. As part of this balancing act, fraudulentinsurance practices are a major business risk that must be managed and overcome. Disputes between insurers andinsureds over the validity of claims or claims handling practices occasionally escalate into litigation (see insurancebad faith).

MarketingInsurers will often use insurance agents to initially market or underwrite their customers. Agents can be captive,meaning they write only for one company, or independent, meaning that they can issue policies from severalcompanies. The existence and success of companies using insurance agents is likely due to improved andpersonalized service.[12]

History of insuranceIn some sense we can say that insurance appears simultaneously with the appearance of human society. We know oftwo types of economies in human societies: natural or non-monetary economies (using barter and trade with nocentralized nor standardized set of financial instruments) and more modern monetary economies (with markets,currency, financial instruments and so on). The former is more primitive and the insurance in such economies entailsagreements of mutual aid. If one family's house is destroyed the neighbours are committed to help rebuild. Granarieshoused another primitive form of insurance to indemnify against famines. Often informal or formally intrinsic tolocal religious customs, this type of insurance has survived to the present day in some countries where modernmoney economy with its financial instruments is not widespread.Turning to insurance in the modern sense (i.e., insurance in a modern money economy, in which insurance is part of the financial sphere), early methods of transferring or distributing risk were practised by Chinese and Babylonian traders as long ago as the 3rd and 2nd millennia BC, respectively.[13] Chinese merchants travelling treacherous river

rapids would redistribute their wares across many vessels to limit the loss due to any single vessel's capsizing. TheBabylonians developed a system which was recorded in the famous Code of Hammurabi, c. 1750 BC, and practisedby early Mediterranean sailing merchants. If a merchant received a loan to fund his shipment, he would pay thelender an additional sum in exchange for the lender's guarantee to cancel the loan should the shipment be stolen orlost at sea.Achaemenian monarchs of Ancient Persia were the first to insure their people and made it official by registering theinsuring process in governmental notary offices. The insurance tradition was performed each year in Norouz(beginning of the Iranian New Year); the heads of different ethnic groups as well as others willing to take part,presented gifts to the monarch. The most important gift was presented during a special ceremony. When a gift wasworth more than 10,000 Derrik (Achaemenian gold coin) the issue was registered in a special office. This wasadvantageous to those who presented such special gifts. For others, the presents were fairly assessed by theconfidants of the court. Then the assessment was registered in special offices.The purpose of registering was that whenever the person who presented the gift registered by the court was introuble, the monarch and the court would help him. Jahez, a historian and writer, writes in one of his books onancient Iran: "[W]henever the owner of the present is in trouble or wants to construct a building, set up a feast, havehis children married, etc. the one in charge of this in the court would check the registration. If the registered amountexceeded 10,000 Derrik, he or she would receive an amount of twice as much."[14]

A thousand years later, the inhabitants of Rhodes invented the concept of the general average. Merchants whosegoods were being shipped together would pay a proportionally divided premium which would be used to reimburseany merchant whose goods were deliberately jettisoned in order to lighten the ship and save it from total loss.The ancient Athenian "maritime loan" advanced money for voyages with repayment being cancelled if the ship waslost. In the 4th century BC, rates for the loans differed according to safe or dangerous times of year, implying anintuitive pricing of risk with an effect similar to insurance.[15] The Greeks and Romans introduced the origins ofhealth and life insurance c. 600 BCE when they created guilds called "benevolent societies" which cared for thefamilies of deceased members, as well as paying funeral expenses of members. Guilds in the Middle Ages served asimilar purpose. The Talmud deals with several aspects of insuring goods. Before insurance was established in thelate 17th century, "friendly societies" existed in England, in which people donated amounts of money to a generalsum that could be used for emergencies.Separate insurance contracts (i.e., insurance policies not bundled with loans or other kinds of contracts) wereinvented in Genoa in the 14th century, as were insurance pools backed by pledges of landed estates. These newinsurance contracts allowed insurance to be separated from investment, a separation of roles that first proved usefulin marine insurance. Insurance became far more sophisticated in post-Renaissance Europe, and specialized varietiesdeveloped.

Lloyd's of London, pictured in 1991, is one of theworld's leading and most famous insurance

markets

Some forms of insurance had developed in London by the earlydecades of the 17th century. For example, the will of the Englishcolonist Robert Hayman mentions two "policies of insurance" takenout with the diocesan Chancellor of London, Arthur Duck. Of the valueof £100 each, one relates to the safe arrival of Hayman's ship inGuyana and the other is in regard to "one hundred pounds assured bythe said Doctor Arthur Ducke on my life". Hayman's will was signedand sealed on 17 November 1628 but not proved until 1633.[16]

Toward the end of the seventeenth century, London's growingimportance as a centre for trade increased demand for marineinsurance. In the late 1680s, Edward Lloyd opened a coffee house thatbecame a popular haunt of ship owners, merchants, and ships' captains,and thereby a reliable source of the latest shipping news. It became themeeting place for parties wishing to insure cargoes and ships, andthose willing to underwrite such ventures. Today, Lloyd's of Londonremains the leading market (note that it is an insurance market ratherthan a company) for marine and other specialist types of insurance, butit operates rather differently than the more familiar kinds of insurance.Insurance as we know it today can be traced to the Great Fire ofLondon, which in 1666 devoured more than 13,000 houses. Thedevastating effects of the fire converted the development of insurance"from a matter of convenience into one of urgency, a change of opinionreflected in Sir Christopher Wren's inclusion of a site for 'the InsuranceOffice' in his new plan for London in 1667."[17] A number of attempted fire insurance schemes came to nothing, butin 1681 Nicholas Barbon, and eleven associates, established England's first fire insurance company, the 'InsuranceOffice for Houses', at the back of the Royal Exchange. Initially, 5,000 homes were insured by Barbon's InsuranceOffice.[18]

The first insurance company in the United States underwrote fire insurance and was formed in Charles Town(modern-day Charleston), South Carolina, in 1732. Benjamin Franklin helped to popularize and make standard thepractice of insurance, particularly against fire in the form of perpetual insurance. In 1752, he founded thePhiladelphia Contributionship for the Insurance of Houses from Loss by Fire.[19] Franklin's company was the first tomake contributions toward fire prevention. Not only did his company warn against certain fire hazards, it refused toinsure certain buildings where the risk of fire was too great, such as all wooden houses.In the United States, regulation of the insurance industry primary resides with individual state insurance departments.The current state insurance regulatory framework has its roots in the 19th century, when New Hampshire appointedthe first insurance commissioner in 1851.[19] Congress adopted the McCarran-Ferguson Act in 1945, which declaredthat states should regulate the business of insurance and to affirm that the continued regulation of the insuranceindustry by the states is in the public's best interest.[19] The Financial Modernization Act of 1999, commonly referredto as "Gramm-Leach-Bliley", established a comprehensive framework to authorize affiliations between banks,securities firms, and insurers, and once again acknowledged that states should regulate insurance.[19]

Whereas insurance markets have become centralized nationally and internationally, state insurance commissionersoperate individually, though at times in concert through the National Association of Insurance Commissioners. Inrecent years, some have called for a dual state and federal regulatory system (commonly referred to as the Optionalfederal charter (OFC)) for insurance similar to the banking industry.In 2010, the federal Dodd-Frank Wall Street Reform and Consumer Protection Act established the Federal Insurance Office ("FIO").[20] FIO is part of the U.S. Department of the Treasury and it monitors all aspects of the insurance

industry, including identifying issues or gaps in the regulation of insurers that may contribute to a systemic crisis inthe insurance industry or in the U.S. financial system.[20] FIO coordinates and develops federal policy on prudentialaspects of international insurance matters, including representing the U.S. in the International Association ofInsurance Supervisors.[20] FIO also assists the U.S. Secretary of Treasury with negotiating (with the U.S. TradeRepresentative) certain international agreements.[20]

Moreover, FIO monitors access to affordable insurance by traditionally underserved communities and consumers,minorities, and low- and moderate-income persons.[20] The Office also assists the U.S. Secretary of the Treasurywith administering the Terrorism Risk Insurance Program.[20] However, FIO is not a regulator or supervisor.[20] Theregulation of insurance continues to reside with the states.[20]

Types of insuranceAny risk that can be quantified can potentially be insured. Specific kinds of risk that may give rise to claims areknown as perils. An insurance policy will set out in detail which perils are covered by the policy and which are not.Below are non-exhaustive lists of the many different types of insurance that exist. A single policy may cover risks inone or more of the categories set out below. For example, vehicle insurance would typically cover both the propertyrisk (theft or damage to the vehicle) and the liability risk (legal claims arising from an accident). A home insurancepolicy in the US typically includes coverage for damage to the home and the owner's belongings, certain legal claimsagainst the owner, and even a small amount of coverage for medical expenses of guests who are injured on theowner's property.Business insurance can take a number of different forms, such as the various kinds of professional liability insurance,also called professional indemnity (PI), which are discussed below under that name; and the business owner's policy(BOP), which packages into one policy many of the kinds of coverage that a business owner needs, in a wayanalogous to how homeowners' insurance packages the coverages that a homeowner needs.[21]

Auto insurance

A wrecked vehicle in Copenhagen

Auto insurance protects the policyholder against financial loss in theevent of an incident involving a vehicle they own, such as in a trafficcollision.

Coverage typically includes:1.1. Property coverage, for damage to or theft of the car;2.2. Liability coverage, for the legal responsibility to others for bodily

injury or property damage;3.3. Medical coverage, for the cost of treating injuries, rehabilitation and

sometimes lost wages and funeral expenses.Most countries, such as the United Kingdom, require drivers to buysome, but not all, of these coverages. When a car is used as collateral for a loan the lender usually requires specificcoverage.

Home insuranceHome insurance provides coverage for damage or destruction of the policyholder's home. In some geographicalareas, the policy may exclude certain types of risks, such as flood or earthquake, that require additional coverage.Maintenance-related issues are typically the homeowner's responsibility. The policy may include inventory, or thiscan be bought as a separate policy, especially for people who rent housing. In some countries, insurers offer apackage which may include liability and legal responsibility for injuries and property damage caused by members ofthe household, including pets.[22]

Health insurance policies cover the cost of medical treatments. Dentalinsurance, like medical insurance protects policyholders for dentalcosts. In the US and Canada, dental insurance is often part of anemployer's benefits package, along with health insurance.

Accident, sickness and unemployment insurance

Workers' compensation, or employers' liabilityinsurance, is compulsory in some countries

• Disability insurance policies provide financial support in the eventof the policyholder becoming unable to work because of disablingillness or injury. It provides monthly support to help pay suchobligations as mortgage loans and credit cards. Short-term andlong-term disability policies are available to individuals, butconsidering the expense, long-term policies are generally obtainedonly by those with at least six-figure incomes, such as doctors,lawyers, etc. Short-term disability insurance covers a person for aperiod typically up to six months, paying a stipend each month tocover medical bills and other necessities.

•• Long-term disability insurance covers an individual's expenses forthe long term, up until such time as they are considered permanentlydisabled and thereafter. Insurance companies will often try to encourage the person back into employment inpreference to and before declaring them unable to work at all and therefore totally disabled.

• Disability overhead insurance allows business owners to cover the overhead expenses of their business while theyare unable to work.

• Total permanent disability insurance provides benefits when a person is permanently disabled and can no longerwork in their profession, often taken as an adjunct to life insurance.

• Workers' compensation insurance replaces all or part of a worker's wages lost and accompanying medicalexpenses incurred because of a job-related injury.

CasualtyCasualty insurance insures against accidents, not necessarily tied to any specific property. It is a broad spectrum ofinsurance that a number of other types of insurance could be classified, such as auto, workers compensation, andsome liability insurances.• Crime insurance is a form of casualty insurance that covers the policyholder against losses arising from the

criminal acts of third parties. For example, a company can obtain crime insurance to cover losses arising fromtheft or embezzlement.

• Political risk insurance is a form of casualty insurance that can be taken out by businesses with operations incountries in which there is a risk that revolution or other political conditions could result in a loss.

LifeLife insurance provides a monetary benefit to a decedent's family or other designated beneficiary, and mayspecifically provide for income to an insured person's family, burial, funeral and other final expenses. Life insurancepolicies often allow the option of having the proceeds paid to the beneficiary either in a lump sum cash payment oran annuity.Annuities provide a stream of payments and are generally classified as insurance because they are issued byinsurance companies, are regulated as insurance, and require the same kinds of actuarial and investment managementexpertise that life insurance requires. Annuities and pensions that pay a benefit for life are sometimes regarded asinsurance against the possibility that a retiree will outlive his or her financial resources. In that sense, they are thecomplement of life insurance and, from an underwriting perspective, are the mirror image of life insurance.Certain life insurance contracts accumulate cash values, which may be taken by the insured if the policy issurrendered or which may be borrowed against. Some policies, such as annuities and endowment policies, arefinancial instruments to accumulate or liquidate wealth when it is needed.In many countries, such as the US and the UK, the tax law provides that the interest on this cash value is not taxableunder certain circumstances. This leads to widespread use of life insurance as a tax-efficient method of saving aswell as protection in the event of early death.In the US, the tax on interest income on life insurance policies and annuities is generally deferred. However, in somecases the benefit derived from tax deferral may be offset by a low return. This depends upon the insuring company,the type of policy and other variables (mortality, market return, etc.). Moreover, other income tax saving vehicles(e.g., IRAs, 401(k) plans, Roth IRAs) may be better alternatives for value accumulation.

Burial insurance

Burial insurance is a very old type of life insurance which is paid out upon death to cover final expenses, such as thecost of a funeral. The Greeks and Romans introduced burial insurance circa 600 AD when they organized guildscalled "benevolent societies" which cared for the surviving families and paid funeral expenses of members upondeath. Guilds in the Middle Ages served a similar purpose, as did friendly societies during Victorian times.

Property insurance provides protection against risks to property, suchas fire, theft or weather damage. This may include specialized forms ofinsurance such as fire insurance, flood insurance, earthquake insurance,home insurance, inland marine insurance or boiler insurance. The termproperty insurance may, like casualty insurance, be used as a broadcategory of various subtypes of insurance, some of which are listedbelow:

• Aviation insurance protects aircraft hulls and spares, and associatedliability risks, such as passenger and third-party liability. Airportsmay also appear under this subcategory, including air traffic controland refuelling operations for international airports through tosmaller domestic exposures.

• Boiler insurance (also known as boiler and machinery insurance, orequipment breakdown insurance) insures against accidental physicaldamage to boilers, equipment or machinery.

• Builder's risk insurance insures against the risk of physical loss ordamage to property during construction. Builder's risk insurance is typically written on an "all risk" basis coveringdamage arising from any cause (including the negligence of the insured) not otherwise expressly excluded.Builder's risk insurance is coverage that protects a person's or organization's insurable interest in materials,fixtures and/or equipment being used in the construction or renovation of a building or structure should thoseitems sustain physical loss or damage from an insured peril.[23]

• Crop insurance may be purchased by farmers to reduce or manage various risks associated with growing crops.Such risks include crop loss or damage caused by weather, hail, drought, frost damage, insects, or disease.[24]

• Earthquake insurance is a form of property insurance that pays the policyholder in the event of an earthquake thatcauses damage to the property. Most ordinary home insurance policies do not cover earthquake damage.Earthquake insurance policies generally feature a high deductible. Rates depend on location and hence thelikelihood of an earthquake, as well as the construction of the home.

• Fidelity bond is a form of casualty insurance that covers policyholders for losses incurred as a result of fraudulentacts by specified individuals. It usually insures a business for losses caused by the dishonest acts of its employees.

Hurricane Katrina caused over $80 billion ofstorm and flood damage

• Flood insurance protects against property loss due to flooding.Many insurers in the US do not provide flood insurance in someparts of the country. In response to this, the federal governmentcreated the National Flood Insurance Program which serves as theinsurer of last resort.

• Home insurance, also commonly called hazard insurance, orhomeowners insurance (often abbreviated in the real estate industryas HOI), is the type of property insurance that covers private homes,as outlined above.

• Landlord insurance covers residential and commercial propertieswhich are rented to others. Most homeowners' insurance covers only owner-occupied homes.

• Marine insurance and marine cargo insurance cover the loss ordamage of vessels at sea or on inland waterways, and of cargo intransit, regardless of the method of transit. When the owner of thecargo and the carrier are separate corporations, marine cargoinsurance typically compensates the owner of cargo for lossessustained from fire, shipwreck, etc., but excludes losses that can berecovered from the carrier or the carrier's insurance. Many marineinsurance underwriters will include "time element" coverage in suchpolicies, which extends the indemnity to cover loss of profit andother business expenses attributable to the delay caused by acovered loss.

The demand for terrorism insurance surged after9/11

• Terrorism insurance provides protection against any loss or damagecaused by terrorist activities. In the US in the wake of 9/11, theTerrorism Risk Insurance Act 2002 (TRIA) set up a federal Programproviding a transparent system of shared public and privatecompensation for insured losses resulting from acts of terrorism.The program was extended until the end of 2014 by the TerrorismRisk Insurance Program Reauthorization Act 2007 (TRIPRA).

• Volcano insurance is a specialized insurance protecting againstdamage arising specifically from volcanic eruptions.

• Windstorm insurance is an insurance covering the damage that canbe caused by wind events such as hurricanes.

LiabilityLiability insurance is a very broad superset that covers legal claims against the insured. Many types of insuranceinclude an aspect of liability coverage. For example, a homeowner's insurance policy will normally include liabilitycoverage which protects the insured in the event of a claim brought by someone who slips and falls on the property;automobile insurance also includes an aspect of liability insurance that indemnifies against the harm that a crashingcar can cause to others' lives, health, or property. The protection offered by a liability insurance policy is twofold: alegal defense in the event of a lawsuit commenced against the policyholder and indemnification (payment on behalfof the insured) with respect to a settlement or court verdict. Liability policies typically cover only the negligence ofthe insured, and will not apply to results of wilful or intentional acts by the insured.

• Errors and omissions insurance is business liability insurance forprofessionals such as insurance agents, real estate agents and brokers, architects, third-party administrators(TPAs) and other business professionals.

• Prize indemnity insurance protects the insured from giving away a large prize at a specific event. Examples wouldinclude offering prizes to contestants who can make a half-court shot at a basketball game, or a hole-in-one at agolf tournament.

• Professional liability insurance, also called professional indemnity insurance (PI), protects insured professionals such as architectural corporations and medical practitioners against potential negligence claims made by their patients/clients. Professional liability insurance may take on different names depending on the profession. For example, professional liability insurance in reference to the medical profession may be called medical malpractice

CreditCredit insurance repays some or all of a loan when certain circumstances arise to the borrower such asunemployment, disability, or death.• Mortgage insurance insures the lender against default by the borrower. Mortgage insurance is a form of credit

insurance, although the name "credit insurance" more often is used to refer to policies that cover other kinds ofdebt.

•• Many credit cards offer payment protection plans which are a form of credit insurance.• Accounts receivable insurance, also known as credit or trade credit insurance is business insurance over the

accounts receivables of the insured. The policy pays the policy holder for covered accounts receivable if thedebtor defaults on payment.

Other types• All-risk insurance is an insurance that covers a wide-range of incidents and perils, except those noted in the

policy. All-risk insurance is different from peril-specific insurance that cover losses from only those perils listedin the policy.[25] In car insurance, all-risk policy includes also the damages caused by the own driver.

• Collateral protection insurance (CPI) insures property (primarilyvehicles) held as collateral for loans made by lending institutions.

• Defense Base Act (DBA) insurance provides coverage for civilianworkers hired by the government to perform contracts outside the US and Canada. DBA is required for all UScitizens, US residents, US Green Card holders, and all employees or subcontractors hired on overseas governmentcontracts.

When something happens which triggers the need for legal action, it is known as "the event". Thereare two main types of legal expenses insurance: before the event insurance and after the event insurance.

• Locked funds insurance is a little-known hybrid insurance policy jointly issued by governments and banks. It isused to protect public funds from tamper by unauthorized parties. In special cases, a government may authorizeits use in protecting semi-private funds which are liable to tamper. The terms of this type of insurance are usuallyvery strict. Therefore it is used only in extreme cases where maximum security of funds is required.

• Livestock insurance is a specialist policy provided to, for example, commercial or hobby farms, aquariums, fishfarms or any other animal holding.

Thepolicy usually covers the costs of cleanup and may include coverage for releases from underground storage tanks.Intentional acts are specifically excluded.

• Purchase insurance is aimed at providing protection on the products people purchase. Purchase insurance cancover individual purchase protection, warranties, guarantees, care plans and even mobile phone insurance. Suchinsurance is normally very limited in the scope of problems that are covered by the policy.

• Title insurance provides a guarantee that title to real property is vested in the purchaser and/or mortgagee, freeand clear of liens or encumbrances. It is usually issued in conjunction with a search of the public recordsperformed at the time of a real estate transaction.

• Travel insurance is an insurance cover taken by those who travel abroad, which covers certain losses such asmedical expenses, loss of personal belongings, travel delay, and personal liabilities.

• Tuition insurance insures students against involuntary withdrawal from cost-intensive educational institutions• Interest rate insurance protects the holder from adverse changes in interest rates, for instance for those with a

variable rate loan or mortgage

Insurance financing vehicles• Fraternal insurance is provided on a cooperative basis by fraternal benefit societies or other social

organizations.[26]

• No-fault insurance is a type of insurance policy (typically automobile insurance) where insureds are indemnifiedby their own insurer regardless of fault in the incident.

•• Protected self-insurance is an alternative risk financing mechanism in which an organization retains themathematically calculated cost of risk within the organization and transfers the catastrophic risk with specific andaggregate limits to an insurer so the maximum total cost of the program is known. A properly designed andunderwritten Protected Self-Insurance Program reduces and stabilizes the cost of insurance and provides valuablerisk management information.

•• Retrospectively rated insurance is a method of establishing a premium on large commercial accounts. The finalpremium is based on the insured's actual loss experience during the policy term, sometimes subject to a minimumand maximum premium, with the final premium determined by a formula. Under this plan, the current year'spremium is based partially (or wholly) on the current year's losses, although the premium adjustments may takemonths or years beyond the current year's expiration date. The rating formula is guaranteed in the insurancecontract. Formula: retrospective premium = converted loss + basic premium × tax multiplier. Numerousvariations of this formula have been developed and are in use.

• Formal self insurance is the deliberate decision to pay for otherwise insurable losses out of one's own money. This can be done on a formal basis by establishing a separate fund into which funds are deposited on a periodic basis, or by simply forgoing the purchase of available insurance and paying out-of-pocket. Self insurance is usually used to pay for high-frequency, low-severity losses. Such losses, if covered by conventional insurance, mean having to pay a premium that includes loadings for the company's general expenses, cost of putting the policy on the books, acquisition expenses, premium taxes, and contingencies. While this is true for all insurance, for small, frequent

losses the transaction costs may exceed the benefit of volatility reduction that insurance otherwise affords.• Reinsurance is a type of insurance purchased by insurance companies or self-insured employers to protect against

unexpected losses. Financial reinsurance is a form of reinsurance that is primarily used for capital managementrather than to transfer insurance risk.

• Social insurance can be many things to many people in many countries. But a summary of its essence is that it is acollection of insurance coverages (including components of life insurance, disability income insurance,unemployment insurance, health insurance, and others), plus retirement savings, that requires participation by allcitizens. By forcing everyone in society to be a policyholder and pay premiums, it ensures that everyone canbecome a claimant when or if he/she needs to. Along the way this inevitably becomes related to other conceptssuch as the justice system and the welfare state. This is a large, complicated topic that engenders tremendousdebate, which can be further studied in the following articles (and others):•• National Insurance•• Social safety net•• Social security•• Social Security debate (United States)•• Social Security (United States)•• Social welfare provision

•• Stop-loss insurance provides protection against catastrophic or unpredictable losses. It is purchased byorganizations who do not want to assume 100% of the liability for losses arising from the plans. Under a stop-losspolicy, the insurance company becomes liable for losses that exceed certain limits called deductibles.

Closed community self-insuranceSome communities prefer to create virtual insurance amongst themselves by other means than contractual risktransfer, which assigns explicit numerical values to risk. A number of religious groups, including the Amish andsome Muslim groups, depend on support provided by their communities when disasters strike. The risk presented byany given person is assumed collectively by the community who all bear the cost of rebuilding lost property andsupporting people whose needs are suddenly greater after a loss of some kind. In supportive communities whereothers can be trusted to follow community leaders, this tacit form of insurance can work. In this manner thecommunity can even out the extreme differences in insurability that exist among its members. Some furtherjustification is also provided by invoking the moral hazard of explicit insurance contracts.In the United Kingdom, The Crown (which, for practical purposes, meant the civil service) did not insure propertysuch as government buildings. If a government building was damaged, the cost of repair would be met from publicfunds because, in the long run, this was cheaper than paying insurance premiums. Since many UK governmentbuildings have been sold to property companies, and rented back, this arrangement is now less common and mayhave disappeared altogether.

Insurance companiesInsurance companies may be classified into two groups:•• Life insurance companies, which sell life insurance, annuities and pensions products.•• Non-life, general, or property/casualty insurance companies, which sell other types of insurance.General insurance companies can be further divided into these sub categories.•• Standard lines•• Excess linesIn most countries, life and non-life insurers are subject to different regulatory regimes and different tax and accounting rules. The main reason for the distinction between the two types of company is that life, annuity, and

Insurance 46

pension business is very long-term in nature — coverage for life assurance or a pension can cover risks over manydecades. By contrast, non-life insurance cover usually covers a shorter period, such as one year.In the United States, standard line insurance companies are insurers that have received a license or authorizationfrom a state for the purpose of writing specific kinds of insurance in that state, such as automobile insurance orhomeowners' insurance.[27] They are typically referred to as "admitted" insurers. Generally, such an insurancecompany must submit its rates and policy forms to the state's insurance regulator to receive his or her prior approval,although whether an insurance company must receive prior approval depends upon the kind of insurance beingwritten. Standard line insurance companies usually charge lower premiums than excess line insurers and may selldirectly to individual insureds. They are regulated by state laws, which include restrictions on rates and forms, andwhich aim to protect consumers and the public from unfair or abusive practices.[27] These insurers also are requiredto contribute to state guarantee funds, which are used to pay for losses if an insurer becomes insolvent.[27]

Excess line insurance companies (also known as Excess and Surplus) typically insure risks not covered by thestandard lines insurance market, due to a variety of reasons (e.g., new entity or an entity that does not have anadequate loss history, an entity with unique risk characteristics, or an entity that has a loss history that does not fit theunderwriting requirements of the standard lines insurance market).[27] They are typically referred to as non-admittedor unlicensed insurers.[27] Non-admitted insurers are generally not licensed or authorized in the states in which theywrite business, although they must be licensed or authorized in the state in which they are domiciled.[27] Thesecompanies have more flexibility and can react faster than standard line insurance companies because they are notrequired to file rates and forms.[27] However, they still have substantial regulatory requirements placed upon them.Most states require that excess line insurers submit financial information, articles of incorporation, a list of officers,and other general information.[27] They also may not write insurance that is typically available in the admittedmarket, do not participate in state guarantee funds (and therefore policyholders do not have any recourse throughthese funds if an insurer becomes insolvent and cannot pay claims), may pay higher taxes, only may write coveragefor a risk if it has been rejected by three different admitted insurers, and only when the insurance producer placingthe business has a surplus lines license.[27] Generally, when an excess line insurer writes a policy, it must, pursuantto state laws, provide disclosure to the policyholder that the policyholder's policy is being written by an excess lineinsurer.[27]

On July 21, 2010, President Barack Obama signed into law the Nonadmitted and Reinsurance Reform Act of 2010("NRRA"), which took effect on July 21, 2011 and was part of the Dodd-Frank Wall Street Reform and ConsumerProtection Act. The NRRA changed the regulatory paradigm for excess line insurance. Generally, under the NRRA,only the insured's home state may regulate and tax the excess line transaction.[28]

Insurance companies are generally classified as either mutual or stock companies. Mutual companies are owned bythe policyholders, while stockholders (who may or may not own policies) own stock insurance companies.Demutualization of mutual insurers to form stock companies, as well as the formation of a hybrid known as a mutualholding company, became common in some countries, such as the United States, in the late 20th century. However,not all states permit mutual holding companies.Other possible forms for an insurance company include reciprocals, in which policyholders reciprocate in sharingrisks, and Lloyd's organizations.Insurance companies are rated by various agencies such as A. M. Best. The ratings include the company's financialstrength, which measures its ability to pay claims. It also rates financial instruments issued by the insurancecompany, such as bonds, notes, and securitization products.Reinsurance companies are insurance companies that sell policies to other insurance companies, allowing them toreduce their risks and protect themselves from very large losses. The reinsurance market is dominated by a few verylarge companies, with huge reserves. A reinsurer may also be a direct writer of insurance risks as well.

Captive insurance companies may be defined as limited-purpose insurance companies established with the specificobjective of financing risks emanating from their parent group or groups. This definition can sometimes be extendedto include some of the risks of the parent company's customers. In short, it is an in-house self-insurance vehicle.Captives may take the form of a "pure" entity (which is a 100% subsidiary of the self-insured parent company); of a"mutual" captive (which insures the collective risks of members of an industry); and of an "association" captive(which self-insures individual risks of the members of a professional, commercial or industrial association). Captivesrepresent commercial, economic and tax advantages to their sponsors because of the reductions in costs they helpcreate and for the ease of insurance risk management and the flexibility for cash flows they generate. Additionally,they may provide coverage of risks which is neither available nor offered in the traditional insurance market atreasonable prices.The types of risk that a captive can underwrite for their parents include property damage, public and productliability, professional indemnity, employee benefits, employers' liability, motor and medical aid expenses. Thecaptive's exposure to such risks may be limited by the use of reinsurance.Captives are becoming an increasingly important component of the risk management and risk financing strategy oftheir parent. This can be understood against the following background:•• heavy and increasing premium costs in almost every line of coverage;•• difficulties in insuring certain types of fortuitous risk;•• differential coverage standards in various parts of the world;•• rating structures which reflect market trends rather than individual loss experience;•• insufficient credit for deductibles and/or loss control efforts.There are also companies known as 'insurance consultants'. Like a mortgage broker, these companies are paid a feeby the customer to shop around for the best insurance policy amongst many companies. Similar to an insuranceconsultant, an 'insurance broker' also shops around for the best insurance policy amongst many companies. However,with insurance brokers, the fee is usually paid in the form of commission from the insurer that is selected rather thandirectly from the client.Neither insurance consultants nor insurance brokers are insurance companies and no risks are transferred to them ininsurance transactions. Third party administrators are companies that perform underwriting and sometimes claimshandling services for insurance companies. These companies often have special expertise that the insurancecompanies do not have.The financial stability and strength of an insurance company should be a major consideration when buying aninsurance contract. An insurance premium paid currently provides coverage for losses that might arise many years inthe future. For that reason, the viability of the insurance carrier is very important. In recent years, a number ofinsurance companies have become insolvent, leaving their policyholders with no coverage (or coverage only from agovernment-backed insurance pool or other arrangement with less attractive payouts for losses). A number ofindependent rating agencies provide information and rate the financial viability of insurance companies.

Life insurance premiums written in 2005

Global insurance premiums grew by 2.7% in inflation-adjusted termsin 2010 to $4.3 trillion, climbing abovepre-crisis levels. The return togrowth and record premiums generated during the year followed twoyears of decline in real terms. Life insurance premiums increased by3.2% in 2010 and non-life premiums by 2.1%. While industrialisedcountries saw an increase in premiums of around 1.4%, insurance

Non-life insurance premiums written in 2005

markets in emerging economies saw rapid expansion with 11% growthin premium income. The global insurance industry was sufficientlycapitalised to withstand the financial crisis of 2008 and 2009 and mostinsurance companies restored their capital to pre-crisis levels by theend of 2010. With the continuation of the gradual recovery of theglobal economy, it is likely the insurance industry will continue to seegrowth in premium income both in industrialised countries andemerging markets in 2011.Advanced economies account for the bulk of global insurance. With premium income of $1,620bn, Europe was themost important region in 2010, followed by North America $1,409bn and Asia $1,161bn. Europe has however seen adecline in premium income during the year in contrast to the growth seen in North America and Asia. The top fourcountries generated more than a half of premiums. The US and Japan alone accounted for 40% of world insurance,much higher than their 7% share of the global population. Emerging economies accounted forover 85% of theworld’s population but only around 15% of premiums. Their markets are however growing at a quicker pace. [29]

Regulatory differencesIn the United States, insurance is regulated by the states under the McCarran-Ferguson Act, with "periodic proposalsfor federal intervention", and a nonprofit coalition of state insurance agencies called the National Association ofInsurance Commissioners works to harmonize the country's different laws and regulations.[30] The NationalConference of Insurance Legislators (NCOIL) also works to harmonize the different state laws.[31]

In the European Union, the Third Non-Life Directive and the Third Life Directive, both passed in 1992 and effective1994, created a single insurance market in Europe and allowed insurance companies to offer insurance anywhere inthe EU (subject to permission from authority in the head office) and allowed insurance consumers to purchaseinsurance from any insurer in the EU.[32]

The insurance industry in China was nationalized in 1949 and thereafter offered by only a single state-ownedcompany, the People's Insurance Company of China, which was eventually suspended as demand declined in acommunist environment. In 1978, market reforms led to an increase in the market and by 1995 a comprehensiveInsurance Law of the People's Republic of China[33] was passed, followed in 1998 by the formation of ChinaInsurance Regulatory Commission (CIRC), which has broad regulatory authority over the insurance market ofChina.[34]

Controversies

Insurance insulates too muchAn insurance company may inadvertently find that its insureds may not be as risk-averse as they might otherwise be(since, by definition, the insured has transferred the risk to the insurer), a concept known as moral hazard. To reducetheir own financial exposure, insurance companies have contractual clauses that mitigate their obligation to providecoverage if the insured engages in behavior that grossly magnifies their risk of loss or liability.For example, life insurance companies may require higher premiums or deny coverage altogether to people whowork in hazardous occupations or engage in dangerous sports. Liability insurance providers do not provide coveragefor liability arising from intentional torts committed by or at the direction of the insured. Even if a provider were soirrational as to want to provide such coverage, it is against the public policy of most countries to allow suchinsurance to exist, and thus it is usually illegal.

Complexity of insurance policy contracts

9/11 was a major insurance loss, but there weredisputes over the World Trade Center's insurance

policy

Insurance policies can be complex and some policyholders may notunderstand all the fees and coverages included in a policy. As a result,people may buy policies on unfavorable terms. In response to theseissues, many countries have enacted detailed statutory and regulatoryregimes governing every aspect of the insurance business, includingminimum standards for policies and the ways in which they may beadvertised and sold.

For example, most insurance policies in the English language todayhave been carefully drafted in plain English; the industry learned thehard way that many courts will not enforce policies against insuredswhen the judges themselves cannot understand what the policies aresaying. Typically, courts construe ambiguities in insurance policiesagainst the insurance company and in favor of coverage under thepolicy.

Many institutional insurance purchasers buy insurance through an insurance broker. While on the surface it appearsthe broker represents the buyer (not the insurance company), and typically counsels the buyer on appropriatecoverage and policy limitations, it should be noted that in the vast majority of cases a broker's compensation comesin the form of a commission as a percentage of the insurance premium, creating a conflict of interest in that thebroker's financial interest is tilted towards encouraging an insured to purchase more insurance than might benecessary at a higher price. A broker generally holds contracts with many insurers, thereby allowing the broker to"shop" the market for the best rates and coverage possible.

Insurance may also be purchased through an agent. Unlike a broker, who represents the policyholder, an agentrepresents the insurance company from whom the policyholder buys. Just as there is a potential conflict of interestwith a broker, an agent has a different type of conflict. Because agents work directly for the insurance company, ifthere is a claim the agent may advise the client to the benefit of the insurance company. It should also be noted thatagents generally can not offer as broad a range of selection compared to an insurance broker.An independent insurance consultant advises insureds on a fee-for-service retainer, similar to an attorney, and thusoffers completely independent advice, free of the financial conflict of interest of brokers and/or agents. However,such a consultant must still work through brokers and/or agents in order to secure coverage for their clients.

Limited consumer benefitsIn United States, economists and consumer advocates generally consider insurance to be worthwhile forlow-probability, catastrophic losses, but not for high-probability, small losses. Because of this, consumers areadvised to select high deductibles and to not insure losses which would not cause a disruption in their life. However,consumers have shown a tendency to prefer low deductibles and to prefer to insure relatively high-probability, smalllosses over low-probability, perhaps due to not understanding or ignoring the low-probability risk.[35] This isassociated with reduced purchasing of insurance against low-probability losses, and may result in increasedinefficiencies from moral hazard.[35]

RedliningRedlining is the practice of denying insurance coverage in specific geographic areas, supposedly because of a highlikelihood of loss, while the alleged motivation is unlawful discrimination. Racial profiling or redlining has a longhistory in the property insurance industry in the United States. From a review of industry underwriting andmarketing materials, court documents, and research by government agencies, industry and community groups, andacademics, it is clear that race has long affected and continues to affect the policies and practices of the insuranceindustry.[36]

In July, 2007, The Federal Trade Commission (FTC) released a report presenting the results of a study concerningcredit-based insurance scores in automobile insurance. The study found that these scores are effective predictors ofrisk. It also showed that African-Americans and Hispanics are substantially overrepresented in the lowest creditscores, and substantially underrepresented in the highest, while Caucasians and Asians are more evenly spread acrossthe scores. The credit scores were also found to predict risk within each of the ethnic groups, leading the FTC toconclude that the scoring models are not solely proxies for redlining. The FTC indicated little data was available toevaluate benefit of insurance scores to consumers.[37] The report was disputed by representatives of the ConsumerFederation of America, the National Fair Housing Alliance, the National Consumer Law Center, and the Center forEconomic Justice, for relying on data provided by the insurance industry. [38]

All states have provisions in their rate regulation laws or in their fair trade practice acts that prohibit unfairdiscrimination, often called redlining, in setting rates and making insurance available.[39]

In determining premiums and premium rate structures, insurers consider quantifiable factors, including location,credit scores, gender, occupation, marital status, and education level. However, the use of such factors is oftenconsidered to be unfair or unlawfully discriminatory, and the reaction against this practice has in some instances ledto political disputes about the ways in which insurers determine premiums and regulatory intervention to limit thefactors used.An insurance underwriter's job is to evaluate a given risk as to the likelihood that a loss will occur. Any factor thatcauses a greater likelihood of loss should theoretically be charged a higher rate. This basic principle of insurancemust be followed if insurance companies are to remain solvent. Thus, "discrimination" against (i.e., negativedifferential treatment of) potential insureds in the risk evaluation and premium-setting process is a necessaryby-product of the fundamentals of insurance underwriting. For instance, insurers charge older people significantlyhigher premiums than they charge younger people for term life insurance. Older people are thus treated differentlythan younger people (i.e., a distinction is made, discrimination occurs). The rationale for the differential treatmentgoes to the heart of the risk a life insurer takes: Old people are likely to die sooner than young people, so the risk ofloss (the insured's death) is greater in any given period of time and therefore the risk premium must be higher tocover the greater risk. However, treating insureds differently when there is no actuarially sound reason for doing sois unlawful discrimination.What is often missing from the debate is that prohibiting the use of legitimate, actuarially sound factors means thatan insufficient amount is being charged for a given risk, and there is thus a deficit in the system. The failure toaddress the deficit may mean insolvency and hardship for all of a company's insureds. The options for addressing the

Page 54: Wikipedia Book Finance

Insurance 51

deficit seem to be the following: Charge the deficit to the other policyholders or charge it to the government (i.e.,externalize outside of the company to society at large).

Insurance patentsFurther information: Insurance patentNew assurance products can now be protected from copying with a business method patent in the United States.A recent example of a new insurance product that is patented is Usage Based auto insurance. Early versions wereindependently invented and patented by a major US auto insurance company, Progressive Auto Insurance (U.S.Patent 5797134 [40]) and a Spanish independent inventor, Salvador Minguijon Perez (EP 0700009 [41]).Many independent inventors are in favor of patenting new insurance products since it gives them protection from bigcompanies when they bring their new insurance products to market. Independent inventors account for 70% of thenew US patent applications in this area.Many insurance executives are opposed to patenting insurance products because it creates a new risk for them. TheHartford insurance company, for example, recently had to pay $80 million to an independent inventor, BancorpServices, in order to settle a patent infringement and theft of trade secret lawsuit for a type of corporate owned lifeinsurance product invented and patented by Bancorp.There are currently about 150 new patent applications on insurance inventions filed per year in the United States.The rate at which patents have issued has steadily risen from 15 in 2002 to 44 in 2006.[42]

Inventors can now have their insurance US patent applications reviewed by the public in the Peer to Patentprogram.[43] The first insurance patent application to be posted was US2009005522 “Risk assessment company” [44].It was posted on March 6, 2009. This patent application describes a method for increasing the ease of changinginsurance companies.[45]

The insurance industry and rent-seekingCertain insurance products and practices have been described as rent-seeking by critics. That is, some insuranceproducts or practices are useful primarily because of legal benefits, such as reducing taxes, as opposed to providingprotection against risks of adverse events. Under United States tax law, for example, most owners of variableannuities and variable life insurance can invest their premium payments in the stock market and defer or eliminatepaying any taxes on their investments until withdrawals are made. Sometimes this tax deferral is the only reasonpeople use these products. Another example is the legal infrastructure which allows life insurance to be held in anirrevocable trust which is used to pay an estate tax while the proceeds themselves are immune from the estate tax.

Religious concernsMuslim scholars have varying opinions about insurance. Insurance policies that earn interest are generallyconsidered to be a form of riba[46] (usury) and some consider even policies that do not earn interest to be a form ofgharar (speculation). Some argue that gharar is not present due to the actuarial science behind the underwriting.[47]

Jewish rabbinical scholars also have expressed reservations regarding insurance as an avoidance of God's will butmost find it acceptable in moderation.[48]

Some Christians believe insurance represents a lack of faith[49] and there is a long history of resistance tocommercial insurance in Anabaptist communities (Mennonites, Amish, Hutterites, Brethren in Christ) but manyparticipate in community-based self-insurance programs that spread risk within their communities.[50][51][52]

Risk Management

DerivativeA derivative instrument is a contract between two parties that specifies conditions (especially the dates, resultingvalues of the underlying variables, and notional amounts) under which payments, or payoffs, are to be made betweenthe parties.[1][2]

Under US law and the laws of most other developed countries, derivatives have special legal exemptions that makethem a particularly attractive legal form through which to extend credit.[3] However, the strong creditor protectionsafforded to derivatives counterparties, in combination with their complexity and lack of transparency, can causecapital markets to underprice credit risk. This can contribute to credit booms, and increase systemic risks.[3] Indeed,the use of derivatives to mask credit risk from third parties while protecting derivative counterparties contributed toboth the financial crisis of 2008 in the United States and the European sovereign debt crises in Greece and Italy.[3][4]

Financial reforms within the US since the financial crisis have served only to reinforce special protections forderivatives, including greater access to government guarantees, while minimizing disclosure to broader financialmarkets.[5]

One of the oldest derivatives is rice futures, which have been traded on the Dojima Rice Exchange since theeighteenth century.[6] Derivatives are broadly categorized by the relationship between the underlying asset and thederivative (such as forward, option, swap); the type of underlying asset (such as equity derivatives, foreign exchangederivatives, interest rate derivatives, commodity derivatives, or credit derivatives); the market in which they trade(such as exchange-traded or over-the-counter); and their pay-off profile.Derivatives can be used for speculating purposes ("bets") or to hedge ("insurance"). For example, a speculator maysell deep in-the-money naked calls on a stock, expecting the stock price to plummet, but exposing himself topotentially unlimited losses. Very commonly, companies buy currency forwards in order to limit losses due tofluctuations in the exchange rate of two currencies.Third parties can use publicly available derivatives prices as educated predictions of uncertain future outcomes, forexample, the likelihood that a corporation will default on its debts.[7]

UsageDerivatives are used by investors for the following:• provide leverage (or gearing), such that a small movement in the underlying value can cause a large difference in

the value of the derivative;[8]

•• speculate and make a profit if the value of the underlying asset moves the way they expect (e.g., moves in a givendirection, stays in or out of a specified range, reaches a certain level);

• hedge or mitigate risk in the underlying, by entering into a derivative contract whose value moves in the oppositedirection to their underlying position and cancels part or all of it out;[9]

• obtain exposure to the underlying where it is not possible to trade in the underlying (e.g., weather derivatives);[10]

• create option ability where the value of the derivative is linked to a specific condition or event (e.g. the underlyingreaching a specific price level).

Page 58: Wikipedia Book Finance

Derivative 55

HedgingDerivatives allow risk related to the price of the underlying asset to be transferred from one party to another. Forexample, a wheat farmer and a miller could sign a futures contract to exchange a specified amount of cash for aspecified amount of wheat in the future. Both parties have reduced a future risk: for the wheat farmer, the uncertaintyof the price, and for the miller, the availability of wheat. However, there is still the risk that no wheat will beavailable because of events unspecified by the contract, such as the weather, or that one party will renege on thecontract. Although a third party, called a clearing house, insures a futures contract, not all derivatives are insuredagainst counter-party risk.From another perspective, the farmer and the miller both reduce a risk and acquire a risk when they sign the futurescontract: the farmer reduces the risk that the price of wheat will fall below the price specified in the contract andacquires the risk that the price of wheat will rise above the price specified in the contract (thereby losing additionalincome that he could have earned). The miller, on the other hand, acquires the risk that the price of wheat will fallbelow the price specified in the contract (thereby paying more in the future than he otherwise would have) andreduces the risk that the price of wheat will rise above the price specified in the contract. In this sense, one party isthe insurer (risk taker) for one type of risk, and the counter-party is the insurer (risk taker) for another type of risk.Hedging also occurs when an individual or institution buys an asset (such as a commodity, a bond that has couponpayments, a stock that pays dividends, and so on) and sells it using a futures contract. The individual or institutionhas access to the asset for a specified amount of time, and can then sell it in the future at a specified price accordingto the futures contract. Of course, this allows the individual or institution the benefit of holding the asset, whilereducing the risk that the future selling price will deviate unexpectedly from the market's current assessment of thefuture value of the asset.

Derivatives traders at the Chicago Board of Trade

Derivatives can serve legitimate business purposes. Forexample, a corporation borrows a large sum of moneyat a specific interest rate.[11] The rate of interest on theloan resets every six months. The corporation isconcerned that the rate of interest may be much higherin six months. The corporation could buy a forward rateagreement (FRA), which is a contract to pay a fixedrate of interest six months after purchases on a notionalamount of money.[12] If the interest rate after sixmonths is above the contract rate, the seller will pay thedifference to the corporation, or FRA buyer. If the rateis lower, the corporation will pay the difference to theseller. The purchase of the FRA serves to reduce theuncertainty concerning the rate increase and stabilizeearnings.

Speculation and arbitrageDerivatives can be used to acquire risk, rather than to hedge against risk. Thus, some individuals and institutions willenter into a derivative contract to speculate on the value of the underlying asset, betting that the party seekinginsurance will be wrong about the future value of the underlying asset. Speculators look to buy an asset in the futureat a low price according to a derivative contract when the future market price is high, or to sell an asset in the futureat a high price according to a derivative contract when the future market price is low.Individuals and institutions may also look for arbitrage opportunities, as when the current buying price of an assetfalls below the price specified in a futures contract to sell the asset.

Derivative 56

Speculative trading in derivatives gained a great deal of notoriety in 1995 when Nick Leeson, a trader at BaringsBank, made poor and unauthorized investments in futures contracts. Through a combination of poor judgment, lackof oversight by the bank's management and regulators, and unfortunate events like the Kobe earthquake, Leesonincurred a US$1.3 billion loss that bankrupted the centuries-old institution.[13]

Types

OTC and exchange-tradedIn broad terms, there are two groups of derivative contracts, which are distinguished by the way they are traded inthe market:• Over-the-counter (OTC) derivatives are contracts that are traded (and privately negotiated) directly between

two parties, without going through an exchange or other intermediary. Products such as swaps, forward rateagreements, exotic options - and other exotic derivatives - are almost always traded in this way. The OTCderivative market is the largest market for derivatives, and is largely unregulated with respect to disclosure ofinformation between the parties, since the OTC market is made up of banks and other highly sophisticated parties,such as hedge funds. Reporting of OTC amounts are difficult because trades can occur in private, without activitybeing visible on any exchange. According to the Bank for International Settlements, the total outstanding notionalamount is US$708 trillion (as of June 2011).[14] Of this total notional amount, 67% are interest rate contracts, 8%are credit default swaps (CDS), 9% are foreign exchange contracts, 2% are commodity contracts, 1% are equitycontracts, and 12% are other. Because OTC derivatives are not traded on an exchange, there is no centralcounter-party. Therefore, they are subject to counter-party risk, like an ordinary contract, since each counter-partyrelies on the other to perform.

• Exchange-traded derivative contracts (ETD) are those derivatives instruments that are traded via specializedderivatives exchanges or other exchanges. A derivatives exchange is a market where individuals tradestandardized contracts that have been defined by the exchange.[15] A derivatives exchange acts as an intermediaryto all related transactions, and takes initial margin from both sides of the trade to act as a guarantee. The world'slargest[16] derivatives exchanges (by number of transactions) are the Korea Exchange (which lists KOSPI IndexFutures & Options), Eurex (which lists a wide range of European products such as interest rate & index products),and CME Group (made up of the 2007 merger of the Chicago Mercantile Exchange and the Chicago Board ofTrade and the 2008 acquisition of the New York Mercantile Exchange). According to BIS, the combined turnoverin the world's derivatives exchanges totaled USD 344 trillion during Q4 2005. Some types of derivativeinstruments also may trade on traditional exchanges. For instance, hybrid instruments such as convertible bondsand/or convertible preferred may be listed on stock or bond exchanges. Also, warrants (or "rights") may be listedon equity exchanges. Performance Rights, Cash xPRTs and various other instruments that essentially consist of acomplex set of options bundled into a simple package are routinely listed on equity exchanges. Like otherderivatives, these publicly traded derivatives provide investors access to risk/reward and volatility characteristicsthat, while related to an underlying commodity, nonetheless are distinctive.

Derivative 57

Common derivative contract typesSome of the common variants of derivative contracts are as follows:1. Forwards:A tailored contract between two parties, where payment takes place at a specific time in the future at

today's pre-determined price.2. Futures: are contracts to buy or sell an asset on or before a future date at a price specified today. A futures

contract differs from a forward contract in that, while the former is a standardized contract written by a clearinghouse that operates an exchange where the contract can be bought and sold, the latter is a non-standardizedcontract written by the parties themselves.

3. Options are contracts that give the owner the right, but not the obligation, to buy (in the case of a call option) orsell (in the case of a put option) an asset. The price at which the sale takes place is known as the strike price, andis specified at the time the parties enter into the option. The option contract also specifies a maturity date. In thecase of a European option, the owner has the right to require the sale to take place on (but not before) the maturitydate; in the case of an American option, the owner can require the sale to take place at any time up to the maturitydate. If the owner of the contract exercises this right, the counter-party has the obligation to carry out thetransaction. Options are of two types: call option and put option. The buyer of a Call option has a right to buy acertain quantity of the underlying asset, at a specified price on or before a given date in the future, he however hasno obligation whatsoever to carry out this right. Similarly, the buyer of a Put option has the right to sell a certainquantity of an underlying asset, at a specified price on or before a given date in the future, he however has noobligation whatsoever to carry out this right.

4. Warrants: Apart from the commonly used short-dated options which have a maximum maturity period of 1 year,there exists certain long-dated options as well, known as Warrant (finance). These are generally tradedover-the-counter.

5. Swaps are contracts to exchange cash (flows) on or before a specified future date based on the underlying valueof currencies exchange rates, bonds/interest rates, commodities exchange, stocks or other assets. Another termwhich is commonly associated to Swap is Swaption which is basically an option on the forward Swap. Similar toa Call and Put option, a Swaption is of two kinds: a receiver Swaption and a payer Swaption. While on one hand,in case of a receiver Swaption there is an option wherein you can receive fixed and pay floating, a payer swaptionon the other hand is an option to pay fixed and receive floating.

Swaps can basically be categorized into two types:• Interest Rate Swap: These basically necessitate swapping only interest associated cash flows in the same

currency, between two parties.• Currency swap: In this kind of swapping, the cash flow between the two parties includes both principal and

interest. Also, the money which is being swapped is in different currency for both parties.[17]

ExamplesThe overall derivatives market has five major classes of underlying asset:• interest rate derivatives (the largest)• foreign exchange derivatives•• credit derivatives•• equity derivatives•• commodity derivativesSome common examples of these derivatives are the following:

Economic function of the derivative marketSome of the salient economic functions of the derivative market include:1. Prices in a structured derivative market not only replicate the discernment of the market participants about the

future but also lead the prices of underlying to the professed future level. On the expiration of the derivativecontract, the prices of derivatives congregate with the prices of the underlying. Therefore, derivatives are essentialtools to determine both current and future prices.

2. The derivatives market relocates risk from the people who prefer risk aversion to the people who have an appetitefor risk.

3. The intrinsic nature of derivatives market associates them to the underlying Spot market. Due to derivatives thereis a considerable increase in trade volumes of the underlying Spot market. The dominant factor behind such anescalation is increased participation by additional players who would not have otherwise participated due toabsence of any procedure to transfer risk.

4. As supervision, reconnaissance of the activities of various participants becomes tremendously difficult in assortedmarkets; the establishment of an organized form of market becomes all the more imperative. Therefore, in thepresence of an organized derivatives market, speculation can be controlled, resulting in a more meticulousenvironment.

5. A significant accompanying benefit which is a consequence of derivatives trading is that it acts as a facilitator for new Entrepreneurs. The derivatives market has a history of alluring many optimistic, imaginative and well

Valuation

Market and arbitrage-freeprices

Two common measures of value are:• Market price, i.e., the price at which

traders are willing to buy or sell thecontract;

• Arbitrage-free price, meaning thatno risk-free profits can be made bytrading in these contracts; seerational pricing.

Determining the market price

For exchange-traded derivatives,market price is usually transparent,making it difficult to automatically broadcast prices. In particular with OTC contracts, there is no central exchange tocollate and disseminate prices.

Determining the arbitrage-free priceSee List of finance topics# Derivatives pricing.

The arbitrage-free price for a derivatives contract can be complex, and there are many different variables to consider.Arbitrage-free pricing is a central topic of financial mathematics. For futures/forwards the arbitrage free price isrelatively straightforward, involving the price of the underlying together with the cost of carry (income received lessinterest costs), although there can be complexities.However, for options and more complex derivatives, pricing involves developing a complex pricing model:understanding the stochastic process of the price of the underlying asset is often crucial. A key equation for thetheoretical valuation of options is the Black–Scholes formula, which is based on the assumption that the cash flowsfrom a European stock option can be replicated by a continuous buying and selling strategy using only the stock. Asimplified version of this valuation technique is the binomial options model.OTC represents the biggest challenge in using models to price derivatives. Since these contracts are not publiclytraded, no market price is available to validate the theoretical valuation. Most of the model's results areinput-dependant (meaning the final price depends heavily on how we derive the pricing inputs).[24] Therefore it iscommon that OTC derivatives are priced by Independent Agents that both counterparties involved in the dealdesignate upfront (when signing the contract).

CriticismDerivatives are often subject to the following criticisms:

Erroneous Analysis of BenefitsEconomists and bankers claimed derivatives made markets safer. But instead, they made them [the markets]unstable.[25]

Hidden Tail RiskAccording to Raghuram Rajan, a former chief economist of the International Monetary Fund (IMF), "... it may wellbe that the managers of these firms [investment funds] have figured out the correlations between the variousinstruments they hold and believe they are hedged. Yet as Chan and others (2005) point out, the lessons of summer1998 following the default on Russian government debt is that correlations that are zero or negative in normal timescan turn overnight to one — a phenomenon they term “phase lock-in.” A hedged position can become unhedged atthe worst times, inflicting substantial losses on those who mistakenly believe they are protected."[26]

RiskThe use of derivatives can result in large losses because of the use of leverage, or borrowing. Derivatives allowinvestors to earn large returns from small movements in the underlying asset's price. However, investors could loselarge amounts if the price of the underlying moves against them significantly. There have been several instances ofmassive losses in derivative markets, such as the following:

• American International Group (AIG) lost more than US$18 billion through a subsidiary over the precedingthree quarters on Credit Default Swaps (CDS).[27] The US federal government then gave the company US$85billion in an attempt to stabilize the economy before an imminent stock market crash. It was reported that thegifting of money was necessary because over the next few quarters, the company was likely to lose moremoney.

• The loss of US$7.2 Billion by Société Générale in January 2008 through mis-use of futures contracts.• The loss of US$6.4 billion in the failed fund Amaranth Advisors, which was long natural gas in September

2006 when the price plummeted.• The loss of US$4.6 billion in the failed fund Long-Term Capital Management in 1998.• The loss of US$1.3 billion equivalent in oil derivatives in 1993 and 1994 by Metallgesellschaft AG.[28]

• The loss of US$1.2 billion equivalent in equity derivatives in 1995 by Barings Bank.[29]

• UBS AG, Switzerland’s biggest bank, suffered a $2 billion loss through unauthorized trading discovered inSeptember, 2011.[30]

Counter party riskSome derivatives (especially swaps) expose investors to counter party risk. Different types of derivatives havedifferent levels of counter party risk. For example, standardized stock options by law require the party at risk to havea certain amount deposited with the exchange, showing that they can pay for any losses; banks that help businessesswap variable for fixed rates on loans may do credit checks on both parties. However, in private agreements betweentwo companies, for example, there may not be benchmarks for performing due diligence and risk analysis.

Page 64: Wikipedia Book Finance

Derivative 61

Large notional valueDerivatives typically have a large notional value. As such, there is the danger that their use could result in losses forwhich the investor would be unable to compensate. The possibility that this could lead to a chain reaction ensuing inan economic crisis was pointed out by famed investor Warren Buffett in Berkshire Hathaway's 2002 annual report.Buffett called them 'financial weapons of mass destruction.' The problem with derivatives is that they control anincreasingly larger notional amount of assets and this may lead to distortions in the real capital and equities markets.Investors begin to look at the derivatives markets to make a decision to buy or sell securities and so what wasoriginally meant to be a market to transfer risk now becomes a leading indicator.(See Berkshire Hathaway AnnualReport for 2002) [31]

Leverage of an economy's debtDerivatives massively leverage the debt in an economy, making it ever more difficult for the underlying realeconomy to service its debt obligations, thereby curtailing real economic activity, which can cause a recession oreven depression. In the view of Marriner S. Eccles, US Federal Reserve Chairman from November, 1934 toFebruary, 1948, too high a level of debt was one of the primary causes of the Great Depression. (See BerkshireHathaway Annual Report for 2002)

BenefitsThe use of derivatives also has its benefits:• Derivatives facilitate the buying and selling of risk, and many financial professionals consider this to have a

positive impact on the economic system. Although someone loses money while someone else gains money with aderivative, under normal circumstances, trading in derivatives should not adversely affect the economic systembecause it is not zero-sum in utility.

Government regulationIn the context of a 2010 examination of the ICE Trust, an industry self-regulatory body, Gary Gensler, the chairmanof the Commodity Futures Trading Commission which regulates most derivatives, was quoted saying that thederivatives marketplace as it functions now "adds up to higher costs to all Americans." More oversight of the banksin this market is needed, he also said. Additionally, the report said, "[t]he Department of Justice is looking intoderivatives, too. The department’s antitrust unit is actively investigating 'the possibility of anticompetitive practicesin the credit derivatives clearing, trading and information services industries,' according to a departmentspokeswoman."[32]

Over-the-counter dealing will be less common as the 2010 Dodd-Frank Wall Street Reform Act comes into effect.The law mandated the clearing of certain swaps at registered exchanges and imposed various restrictions onderivatives. To implement Dodd-Frank, the CFTC developed new rules in at least 30 areas [33]. The Commissiondetermines which swaps are subject to mandatory clearing and whether a derivatives exchange is eligible to clear acertain type of swap contract.

Glossary• Bilateral netting: A legally enforceable arrangement between a bank and a counter-party that creates a single legal

obligation covering all included individual contracts. This means that a bank’s obligation, in the event of thedefault or insolvency of one of the parties, would be the net sum of all positive and negative fair values ofcontracts included in the bilateral netting arrangement.

• Credit derivative: A contract that transfers credit risk from a protection buyer to a credit protection seller. Creditderivative products can take many forms, such as credit default swaps, credit linked notes and total return swaps.

•• Derivative: A financial contract whose value is derived from the performance of assets, interest rates, currencyexchange rates, or indexes. Derivative transactions include a wide assortment of financial contracts includingstructured debt obligations and deposits, swaps, futures, options, caps, floors, collars, forwards and variouscombinations thereof.

• Exchange-traded derivative contracts: Standardized derivative contracts (e.g., futures contracts and options) thatare transacted on an organized futures exchange.

• Gross negative fair value: The sum of the fair values of contracts where the bank owes money to itscounter-parties, without taking into account netting. This represents the maximum losses the bank’scounter-parties would incur if the bank defaults and there is no netting of contracts, and no bank collateral washeld by the counter-parties.

• Gross positive fair value: The sum total of the fair values of contracts where the bank is owed money by itscounter-parties, without taking into account netting. This represents the maximum losses a bank could incur if allits counter-parties default and there is no netting of contracts, and the bank holds no counter-party collateral.

• High-risk mortgage securities: Securities where the price or expected average life is highly sensitive to interestrate changes, as determined by the U.S. Federal Financial Institutions Examination Council policy statement onhigh-risk mortgage securities.

• Notional amount: The nominal or face amount that is used to calculate payments made on swaps and other riskmanagement products. This amount generally does not change hands and is thus referred to as notional.

• Over-the-counter (OTC) derivative contracts: Privately negotiated derivative contracts that are transacted offorganized futures exchanges.

• Structured notes: Non-mortgage-backed debt securities, whose cash flow characteristics depend on one or moreindices and / or have embedded forwards or options.

• Total risk-based capital: The sum of tier 1 plus tier 2 capital. Tier 1 capital consists of common shareholdersequity, perpetual preferred shareholders equity with non-cumulative dividends, retained earnings, and minorityinterests in the equity accounts of consolidated subsidiaries. Tier 2 capital consists of subordinated debt,intermediate-term preferred stock, cumulative and long-term preferred stock, and a portion of a bank’s allowancefor loan and lease losses.

Finance of states

Public financePublic finance is the study of the role of the government in the economy.[1]

The purview of public finance is considered to be threefold: governmental effects on (1) efficient allocation ofresources, (2) distribution of income, and (3) macroeconomic stabilization.

OverviewThe proper role of government provides a starting point for the analysis of public finance. In theory, under certaincircumstances, private markets will allocate goods and services among individuals efficiently (in the sense that nowaste occurs and that individual tastes are matching with the economy's productive abilities). If private markets wereable to provide efficient outcomes and if the distribution of income were socially acceptable, then there would belittle or no scope for government. In many cases, however, conditions for private market efficiency are violated. Forexample, if many people can enjoy the same good at the same time (non-rival, non-excludable consumption), thenprivate markets may supply too little of that good. National defense is one example of non-rival consumption, or of apublic good."Market failure" occurs when private markets do not allocate goods or services efficiently. The existence of marketfailure provides an efficiency-based rationale for collective or governmental provision of goods and services.Externalities, public goods, informational advantages, strong economies of scale, and network effects can causemarket failures. Public provision via a government or a voluntary association, however, is subject to otherinefficiencies, termed "government failure."Under broad assumptions, government decisions about the efficient scope and level of activities can be efficientlyseparated from decisions about the design of taxation systems (Diamond-Mirlees separation). In this view, publicsector programs should be designed to maximize social benefits minus costs (cost-benefit analysis), and thenrevenues needed to pay for those expenditures should be raised through a taxation system that creates the fewestefficiency losses caused by distortion of economic activity as possible. In practice, government budgeting or publicbudgeting is substantially more complicated and often results in inefficient practices.Government can pay for spending by borrowing (for example, with government bonds), although borrowing is amethod of distributing tax burdens through time rather than a replacement for taxes. A deficit is the differencebetween government spending and revenues. The accumulation of deficits over time is the total public debt. Deficitfinance allows governments to smooth tax burdens over time, and gives governments an important fiscal policy tool.Deficits can also narrow the options of successor governments.Public finance is closely connected to issues of income distribution and social equity. Governments can reallocateincome through transfer payments or by designing tax systems that treat high-income and low-income householdsdifferently.The Public Choice approach to public finance seeks to explain how self-interested voters, politicians, andbureaucrats actually operate, rather than how they should operate.

Public finance managementCollection of sufficient resources from the economy in an appropriate manner along with allocating and use of theseresources efficiently and effectively constitute good financial management. Resource generation, resource allocationand expenditure management (resource utilization) are the essential components of a public financial managementsystem.Public Finance Management (PFM) basically deals with all aspects of resource mobilization and expendituremanagement in government. Just as managing finances is a critical function of management in any organization,similarly public finance management is an essential part of the governance process. Public finance managementincludes resource mobilization, prioritization of programmes, the budgetary process, efficient management ofresources and exercising controls. Rising aspirations of people are placing more demands on financial resources. Atthe same time, the emphasis of the citizenry is on value for money, thus making public finance managementincreasingly vital.

Government expendituresEconomists classify government expenditures into three main types. Government purchases of goods and servicesfor current use are classed as government consumption. Government purchases of goods and services intended tocreate future benefits--- such as infrastructure investment or research spending--- are classed as governmentinvestment. Government expenditures that are not purchases of goods and services, and instead just representtransfers of money--- such as social security payments--- are called transfer payments.[2]

Government operationsGovernment operations are those activities involved in the running of a state or a functional equivalent of a state (forexample, tribes, secessionist movements or revolutionary movements) for the purpose of producing value for thecitizens. Government operations have the power to make, and the authority to enforce rules and laws within a civil,corporate, religious, academic, or other organization or group.[3] In its broadest sense, "to govern" means to rule overor supervise, whether over a state, a set group of people, or a collection of people.[4]

Income distribution• Income distribution - Some forms of government expenditure are specifically intended to transfer income from

some groups to others. For example, governments sometimes transfer income to people that have suffered a lossdue to natural disaster. Likewise, public pension programs transfer wealth from the young to the old. Other formsof government expenditure which represent purchases of goods and services also have the effect of changing theincome distribution. For example, engaging in a war may transfer wealth to certain sectors of society. Publiceducation transfers wealth to families with children in these schools. Public road construction transfers wealthfrom people that do not use the roads to those people that do (and to those that build the roads).

Financing of government expenditures

Budgeted revenues of governments in 2006.

Government expenditures are financedin two ways:•• Government revenue

• Taxes• Non-tax revenue (revenue from

government-owned corporations,sovereign wealth funds, sales ofassets, or Seigniorage)

•• Government borrowing•• Privatization

How a government chooses to finance its activities can have important effects on the distribution of income andwealth (income redistribution) and on the efficiency of markets (effect of taxes on market prices and efficiency). Theissue of how taxes affect income distribution is closely related to tax incidence, which examines the distribution oftax burdens after market adjustments are taken into account. Public finance research also analyzes effects of thevarious types of taxes and types of borrowing as well as administrative concerns, such as tax enforcement.

TaxesTaxation is the central part of modern public finance. Its significance arises not only from the fact that it is by far themost important of all revenues but also because of the gravity of the problems created by the present day heavy taxburden. The main objective of taxation is raising revenue. A high level of taxation is necessary in a welfare State tofulfill its obligations. Taxation is used as an instrument of attaining certain social objectives i.e. as a means ofredistribution of wealth and thereby reducing inequalities. Taxation in a modern Government is thus needed notmerely to raise the revenue required to meet its ever-growing expenditure on administration and social services butalso to reduce the inequalities of income and wealth. Taxation is also needed to draw away money that wouldotherwise go into consumption and cause inflation to rise.[5]

A tax is a financial charge or other levy imposed on an individual or a legal entity by a state or a functionalequivalent of a state (for example, tribes, secessionist movements or revolutionary movements). Taxes could also beimposed by a subnational entity. Taxes consist of direct tax or indirect tax, and may be paid in money or as corvéelabor. A tax may be defined as a "pecuniary burden laid upon individuals or property to support the government[ . . .] a payment exacted by legislative authority."[6] A tax "is not a voluntary payment or donation, but an enforcedcontribution, exacted pursuant to legislative authority" and is "any contribution imposed by government [ . . .]whether under the name of toll, tribute, tallage, gabel, impost, duty, custom, excise, subsidy, aid, supply, or othername."[7]

•• There are various types of taxes, broadly divided into two heads - direct (which is proportional) and indirect tax(which is differential in nature):

• Stamp duty, levied on documents• Excise tax (tax levied on production for sale, or sale, of a certain good)• Sales tax (tax on business transactions, especially the sale of goods and services)

• Value added tax (VAT) is a type of sales tax•• Services taxes on specific services

• Road tax; Vehicle excise duty (UK), Registration Fee (USA), Regco (Australia), Vehicle Licensing Fee (Brazil)etc.

•• Gift tax

• Duties (taxes on importation, levied at customs)• Corporate income tax on corporations (incorporated entities)•• Wealth tax• Personal income tax (may be levied on individuals, families such as the Hindu joint family in India,

unincorporated associations, etc.)

Debt

Foreign currency reserves and gold minus external debt based on 2010 data from CIAFactbook.

Governments, like any other legalentity, can take out loans, issue bondsand make financial investments.Government debt (also known aspublic debt or national debt) is money(or credit) owed by any level ofgovernment; either central or federalgovernment, municipal government orlocal government. Some localgovernments issue bonds based ontheir taxing authority, such as taxincrement bonds or revenue bonds.

As the government represents the people, government debt can be seen as an indirect debt of the taxpayers.Government debt can be categorized as internal debt, owed to lenders within the country, and external debt, owed toforeign lenders. Governments usually borrow by issuing securities such as government bonds and bills. Lesscreditworthy countries sometimes borrow directly from commercial banks or international institutions such as theInternational Monetary Fund or the World Bank.

Most government budgets are calculated on a cash basis, meaning that revenues are recognized when collected andoutlays are recognized when paid. Some consider all government liabilities, including future pension payments andpayments for goods and services the government has contracted for but not yet paid, as government debt. Thisapproach is called accrual accounting, meaning that obligations are recognized when they are acquired, or accrued,rather than when they are paid.

SeigniorageSeigniorage is the net revenue derived from the issuing of currency. It arises from the difference between the facevalue of a coin or bank note and the cost of producing, distributing and eventually retiring it from circulation.Seigniorage is an important source of revenue for some national banks, although it provides a very small proportionof revenue for advanced industrial countries.

Public finance through state enterpriseFurther information: State-owned enterprisePublic finance in centrally planned economies has differed in fundamental ways from that in market economies.Some state-owned enterprises generated profits that helped finance government activities. The government entitiesthat operate for profit are usually manufacturing and financial institutions, services such as nationalized healthcaredo not operate for a profit to keep costs low for consumers. The Soviet Union relied heavily on turnover taxes onretail sales. Sales of natural resources, and especially petroleum products, were an important source of revenue forthe Soviet Union.

Public finance 69

In market-oriented economies with substantial state enterprise, such as in Venezuela, the state-run oil companyPSDVA provides revenue for the government to fund its operations and programs that would otherwise be profit forprivate owners. In various mixed economies, the revenue generated by state-run or state-owned enterprises are usedfor various state endeavors; typically the revenue generated by state and government agencies goes into a sovereignwealth fund. An example of this is the Alaska Permanent Fund and Singapore's Temasek Holdings.Various market socialist systems or proposals utilize revenue generated by state-run enterprises to fund socialdividends, eliminating the need for taxation altogether.

Government Finance Statistics and MethodologyMacroeconomic data to support public finance economics are generally referred to as fiscal or government financestatistics (GFS). The Government Finance Statistics Manual 2001 (GFSM 2001) [8] is the internationally acceptedmethodology for compiling fiscal data. It is consistent with regionally accepted methodologies such as the EuropeanSystem of Accounts 1995 [9] and consistent with the methodology of the System of National Accounts (SNA1993) [10]

and broadly in line with its most recent update, the SNA2008 [11].

Challenges in measuring governmentThe size of governments, their institutional composition and complexity, their ability to carry out large andsophisticated operations, and their impact on the other sectors of the economy warrant a well-articulated system tomeasure government economic operations.The GFSM 2001 addresses the institutional complexity of government by defining various levels of government. Themain focus of the GFSM 2001 is the general government sector defined as the group of entities capable ofimplementing public policy through the provision of primarily nonmarket goods and services and the redistributionof income and wealth, with both activities supported mainly by compulsory levies on other sectors. The GFSM 2001disaggregates the general government into subsectors: central government, state government, and local government(See Figure 1). The concept of general government does not include public corporations. The general governmentplus the public corporations comprise the public sector (See Figure 2).

Page 73: Wikipedia Book Finance

Public finance 70

Figure 2: Public Sector(IMF Government Finance Statistics Manual 2001(Washington, 2001)pp.15

The GFSM 2001 framework is similar to the financial accounting of businesses. For example, it recommends thatgovernments produce a full set of financial statements including the statement of government operations (akin to theincome statement), the balance sheet, and a cash flow statement. Two other similarities between the GFSM 2001 andbusiness financial accounting are the recommended use of accrual accounting as the basis of recording and thepresentations of stocks of assets and liabilities at market value. It is an improvement on the prior methodology -Government Finance Statistics Manual 1986 – based on cash flows and without a balance sheet statement.

Users of GFSThe GFSM 2001 recommends standard tables including standard fiscal indicators that meet a broad group of usersincluding policy makers, researchers, and investors in sovereign debt. Government finance statistics should offerdata for topics such as the fiscal architecture, the measurement of the efficiency and effectiveness of governmentexpenditures, the economics of taxation, and the structure of public financing. The GFSM 2001 provides a blueprintfor the compilation, recording, and presentation of revenues, expenditures, stocks of assets, and stocks of liabilities.The GFSM 2001 also defines some indicators of effectiveness in government’s expenditures, for example thecompensation of employees as a percentage of expense. The GFSM 2001 includes a functional classification ofexpense as defined by the Classification of Functions of Government (COFOG) .This functional classification allows policy makers to analyze expenditures on categories such as health, education,social protection, and environmental protection. The financial statements can provide investors with the necessaryinformation to assess the capacity of a government to service and repay its debt, a key element determiningsovereign risk, and risk premia. Like the risk of default of a private corporation, sovereign risk is a function of thelevel of debt, its ratio to liquid assets, revenues and expenditures, the expected growth and volatility of theserevenues and expenditures, and the cost of servicing the debt. The government’s financial statements contain therelevant information for this analysis.The government’s balance sheet presents the level of the debt; that is the government’s liabilities. The memorandumitems of the balance sheet provide additional information on the debt including its maturity and whether it is owed todomestic or external residents. The balance sheet also presents a disaggregated classification of financial andnon-financial assets.

These data help estimate the resources a government can potentially access to repay its debt. The statement ofoperations (“income statement”) contains the revenue and expense accounts of the government. The revenue accountsare divided into subaccounts, including the different types of taxes, social contributions, dividends from the publicsector, and royalties from natural resources. Finally, the interest expense account is one of the necessary inputs toestimate the cost of servicing the debt.

Fiscal Data Using the GFSM 2001 MethodologyGFS can be accessible through several sources. The International Monetary Fund publishes GFS in two publications:International Financial Statistics and the Government Finance Statistics Yearbook. The World Bank gathersinformation on external debt. On a regional level, the Organization for Economic Co-operation and Development(OECD) compiles general government account data for its members, and Eurostat, following a methodologycompatible with the GFSM 2001, compiles GFS for the members of the European Union.

Financial economics

Financial economicsFinancial economics is the branch of economics concerned with "the allocation and deployment of economicresources, both spatially and across time, in an uncertain environment".[1] It is additionally characterised by its"concentration on monetary activities", in which "money of one type or another is likely to appear on both sides of atrade".[2] The questions within financial economics are typically framed in terms of "time, uncertainty, options, andinformation".[2]

•• Time: money now is traded for money in the future.• Uncertainty (or risk): The amount of money to be transferred in the future is uncertain.• Options: one party to the transaction can make a decision at a later time that will affect subsequent transfers of

money.• Information: knowledge of the future can reduce, or possibly eliminate, the uncertainty associated with future

monetary value (FMV).The subject is usually taught at a postgraduate level; see Master of Financial Economics.

Subject matterFinancial economics is the branch of economics studying the interrelation of financial variables, such as prices,interest rates and shares, as opposed to those concerning the real economy. Financial economics concentrates oninfluences of real economic variables on financial ones, in contrast to pure finance.It studies the following:• Valuation - Determination of the fair value of an asset

•• How risky is the asset? (identification of the asset appropriate discount rate)• What cash flows will it produce? (discounting of relevant cash flows)•• How does the market price compare to similar assets? (relative valuation)•• Are the cash flows dependent on some other asset or event? (derivatives, contingent claim valuation)

•• Financial markets and instruments• Commodities - topics• Stocks - topics• Bonds - topics• Money market instruments- topics• Derivatives - topics

• Financial institutions and regulationFinancial Econometrics is the branch of Financial Economics that uses econometric techniques to parameterise therelationships.

Models in financial economicsFinancial economics is primarily concerned with building models to derive testable or policy implications fromacceptable assumptions. Some fundamental ideas in financial economics are portfolio theory, the Capital AssetPricing Model. Portfolio theory studies how investors should balance risk and return when investing in many assetsor securities. The Capital Asset Pricing Model describes how markets should set the prices of assets in relation tohow risky they are. The Modigliani-Miller Theorem describes conditions under which corporate financing decisionsare irrelevant for value, and acts as a benchmark for evaluating the effects of factors outside the model that do affectvalue.A common assumption is that financial decision makers act rationally (see Homo economicus; efficient markethypothesis). However, recently, researchers in experimental economics and experimental finance have challengedthis assumption empirically. They are also challenged, theoretically, by behavioral finance, a discipline primarilyconcerned with the limits to rationality of economic agents.Other common assumptions include market prices following a random walk or asset returns being normallydistributed. Empirical evidence suggests that these assumptions may not hold and that in practice, traders, analystsand particularly risk managers frequently modify the "standard models".

Financial mathematics

Financial mathematicsMathematical finance is a field of applied mathematics, concerned with financial markets. The subject has a closerelationship with the discipline of financial economics, which is concerned with much of the underlying theory.Generally, mathematical finance will derive and extend the mathematical or numerical models suggested by financialeconomics. Thus, for example, while a financial economist might study the structural reasons why a company mayhave a certain share price, a financial mathematician may take the share price as a given, and attempt to usestochastic calculus to obtain the fair value of derivatives of the stock (see: Valuation of options).In terms of practice, mathematical finance also overlaps heavily with the field of computational finance (also knownas financial engineering). Arguably, these are largely synonymous, although the latter focuses on application, whilethe former focuses on modeling and derivation (see: Quantitative analyst), often by help of stochastic asset models.The fundamental theorem of arbitrage-free pricing is one of the key theorems in mathematical finance. Manyuniversities around the world now offer degree and research programs in mathematical finance; see Master ofMathematical Finance.

History: Q versus PThere exist two separate branches of finance that require advanced quantitative techniques: derivatives pricing on theone hand, and risk and portfolio management on the other hand. One of the main differences is that they use differentprobabilities, namely the risk-neutral probability, denoted by "Q", and the actual probability, denoted by "P".

Derivatives pricing: the Q worldFurther information: Black–ScholesThe goal of derivatives pricing is to determine the fair price of a given security in terms of more liquid securitieswhose price is determined by the law of supply and demand. Examples of securities being priced are plain vanillaand exotic options, convertible bonds, etc.Once a fair price has been determined, the sell-side trader can make a market on the security. Therefore, derivativespricing is a complex "extrapolation" exercise to define the current market value of a security, which is then used bythe sell-side community.

Quantitative derivatives pricing was initiated by Louis Bachelier in The Theory of Speculation (published 1900),with the introduction of the most basic and most influential of processes, the Brownian motion, and its applicationsto the pricing of options. However, Bachelier's work hardly caught any attention outside academia.The theory remained dormant until Fischer Black and Myron Scholes, along with fundamental contributions byRobert C. Merton, applied the second most influential process, the geometric Brownian motion, to option pricing.For this M. Scholes and R. Merton were awarded the 1997 Nobel Memorial Prize in Economic Sciences. Black wasineligible for the prize because of his death in 1995.The next important step was the fundamental theorem of asset pricing by Harrison and Pliska (1981), according towhich the suitably normalized current price P0 of a security is arbitrage-free, and thus truly fair, only if there exists astochastic process Pt with constant expected value which describes its future evolution:

(1 )

A process satisfying (1) is called a "martingale". A martingale does not reward risk. Thus the probability of thenormalized security price process is called "risk-neutral" and is typically denoted by the blackboard font letter " ".The relationship (1) must hold for all times t: therefore the processes used for derivatives pricing are naturally set incontinuous time.The quants who operate in the Q world of derivatives pricing are specialists with deep knowledge of the specificproducts they model.Securities are priced individually, and thus the problems in the Q world are low-dimensional in nature. Calibration isone of the main challenges of the Q world: once a continuous-time parametric process has been calibrated to a set oftraded securities through a relationship such as (1), a similar relationship is used to define the price of newderivatives.The main quantitative tools necessary to handle continuous-time Q-processes are Ito’s stochastic calculus and partialdifferential equations (PDE’s).

Risk and portfolio management: the P worldRisk and portfolio management aims at modelling the probability distribution of the market prices of all thesecurities at a given future investment horizon.This "real" probability distribution of the market prices is typically denoted by the blackboard font letter " ", asopposed to the "risk-neutral" probability " " used in derivatives pricing.Based on the P distribution, the buy-side community takes decisions on which securities to purchase in order toimprove the prospective profit-and-loss profile of their positions considered as a portfolio.

The quantitative theory of risk and portfolio management started with the mean-variance framework of Harry Markowitz (1952), who caused a shift away from the concept of trying to identify the best individual stock for

Financial mathematics 78

investment. Using a linear regression strategy to understand and quantify the risk (i.e. variance) and return (i.e.mean) of an entire portfolio of stocks, bonds, and other securities, an optimization strategy was used to choose aportfolio with largest mean return subject to acceptable levels of variance in the return. Next, breakthrough advanceswere made with the Capital Asset Pricing Model (CAPM) and the Arbitrage Pricing Theory (APT) developed byTreynor (1962), Mossin (1966), William Sharpe (1964), Lintner (1965) and Ross (1976).For their pioneering work, Markowitz and Sharpe, along with Merton Miller, shared the 1990 Nobel Memorial Prizein Economic Sciences, for the first time ever awarded for a work in finance.The portfolio-selection work of Markowitz and Sharpe introduced mathematics to the "black art" of investmentmanagement. With time, the mathematics has become more sophisticated. Thanks to Robert Merton and PaulSamuelson, one-period models were replaced by continuous time, Brownian-motion models, and the quadratic utilityfunction implicit in mean–variance optimization was replaced by more general increasing, concave utilityfunctions.[1]

Furthermore, in more recent years the focus shifted toward estimation risk, i.e., the dangers of incorrectly assumingthat advanced time series analysis alone can provide completely accurate estimates of the market parameters [2]

CriticismMore sophisticated mathematical models and derivative pricing strategies were then developed but their credibilitywas damaged by the financial crisis of 2007–2010.Contemporary practice of mathematical finance has been subjected to criticism from figures within the field notablyby Nassim Nicholas Taleb in his book The Black Swan[3] and Paul Wilmott. Taleb claims that the prices of financialassets cannot be characterized by the simple models currently in use, rendering much of current practice at bestirrelevant, and, at worst, dangerously misleading. Wilmott and Emanuel Derman published the Financial Modelers'Manifesto in January 2008[4] which addresses some of the most serious concerns.Bodies such as the Institute for New Economic Thinking are now attempting to establish more effective theories andmethods.[5]

Experimental finance

Experimental financeThe goals of experimental finance are to establish different market settings and environments to observeexperimentally and analyze agents' behavior and the resulting characteristics of trading flows, information diffusionand aggregation, price setting mechanism and returns processes. This can happen for instance by conducting tradingsimulations or establishing and studying the behaviour of people in artificial competitive market-like settings.Researchers in experimental finance can study to what extent existing financial economics theory makes validpredictions and attempt to discover new principles on which theory can be extended.

Method in experimental financeThe methodology of experimental finance is closely related to that of Experimental economics.The fundamental method of experiment economics is to create a setting that implements some institutional featuresof interest, and then provide participants with incentives to maximize utility within that setting.Following the discussion in Bloomfield, Tayler, and Zhou (2009), experimentalists usually classify models as havingthree types of assumptions:•• Structural assumptions describe the institutions in which agents interact, including the distribution of information,

possible actions, and incentives;• Behavioral assumptions characterize agents’ preferences and decision-making abilities (such as expected utility

maximization and the form of the utility function);•• Equilibrium assumptions that describe the solution concepts used to predict behavior (such as Bayesian Nash

Equilibrium, rational expectations, or arbitrate free pricing).Equilibrium assumptions are particularly important in signaling models.Even in settings with a unique equilibrium, there is no guarantee that the equilibrium can be achieved. Anequilibrium is a fixed point—an outcome that, if obtained, will leave no participant wishing to deviate from it. Still,experimentalists are quickly forced to think about the process that would drive participants toward equilibrium ifthey are not already there (convergence), and also about the process that might drive participants away from anequilibrium if, having attained it, they drift infinitesimally far away (instability).

Testing Models that Cannot Be SolvedA final way to avoid the problem of having no plausible alternative hypothesis is to construct a setting in whichtheory is simply unable to provide a unique prediction. This alternative is particularly relevant in marketmicrostructure, which deals with extremely complex settings and strategic problems. The most common market usedin laboratory settings is the double auction, which is simple in execution, but extremely difficult to model (seeFriedman, 1984). Modelers in microstructure will often look at simpler settings, such as Kyle-type orGlosten-Milgrom-type experiments. For example, Bloomfield (1996) uses a Glosten-Milgrom- type setup in whichinvestors and market makers simultaneously submit the best bid and ask at which they are willing to trade. Crossingtrades are then executed, all other orders are canceled and trade moves on to the next period. Orders that are notimmediately marketable do not have any impact on trade as they would in a limit order market. These types ofmodels of quote- or order-driven markets are much less relevant these days, when most trade takes place inelectronic limit order markets.

Individual Bias and Aggregate Market BehaviorA large literature from psychology shows individual errors in judgment. Some of the biases most relevant in thefinancial setting, are outlined by Tversky and Kahneman (1974). These biases include representativeness, thetendency to assume commonality between similar objects; availability, which causes probabilities to be assignedbased on how easily similar examples can be brought to mind; and anchoring, the reliance on a single piece ofinformation or starting point when making an estimate.A key tenet of traditional finance is that markets eliminate these errors. It is suggested that people learn to avoidthese mistakes through experience and incentives,. As people learn, either directly from investment professionals orindirectly through their own experience, irrational investors will be flushed out of the market. Additionally, even ifindividual biases are present in the market, they will likely cancel each other out so that, on aggregate, the marketwill be unbiased.

Experimental Finance and Experimental PsychologyExperimentation has a very long tradition in psychology, but is relatively new to finance and economics. In fact,Chamberlain performed the first experiment in 1948 and Smith laid out the tenets of experimental economics in1976. Camerer (1997) describes many of the differences between the styles of those who conduct experiments basedin economics (the E’s) and psychology (the P’s). Camerer notes a number of key differences in the experiments runby E’s and P’s. Some of the most important are:• E’s insist that participants receive incentive compensation, while P’s rarely do.• E’s typically have experiments with groups of people who interact with one another, while P’s often look at

individual participants’ beliefs and decisions.• E’s typically focus on participant actions that affect aggregate outcomes (e.g., market price) and payoffs, while P’s

often focus on stated beliefs.• E’s typically remove context from their settings, while P’s rarely do. For example, a test of probability assessment

by an E would be described in terms of balls drawn randomly from urns with replacement, while a P would morelikely present a question like “how likely is it that the population of Miami is greater than the population ofParis?”

• E’s often include extremely complex tables of raw data and econometric estimates of parameters, while P’s willusually provide only summary statistics (such as means, variances, F- and t-statistics, and p-values).

Behavioral finance

Behavioral financeBehavioral economics and the related field, behavioral finance, study the effects of social, cognitive and emotionalfactors on the economic decisions of individuals and institutions and the consequences for market prices, returns andthe resource allocation. The fields are primarily concerned with the bounds of rationality of economic agents.Behavioral models typically integrate insights from psychology with neo-classical economic theory. In so doing theycover a range of concepts, methods, and fields.[1]

Behavioral analysts are not only concerned with the effects of market decisions but also with public choice, whichdescribes another source of economic decisions with related biases towards promoting self-interest.

HistoryDuring the classical period, microeconomics was closely linked to psychology. For example, Adam Smith wrote TheTheory of Moral Sentiments, which proposed psychological explanations of individual behavior, including concernsabout fairness and justice,[2] and Jeremy Bentham wrote extensively on the psychological underpinnings of utility.However, during the development of neo-classical economics economists sought to reshape the discipline as anatural science, deducing economic behavior from assumptions about the nature of economic agents. Theydeveloped the concept of homo economicus, whose psychology was fundamentally rational. This led to unintendedand unforeseen errors.However, many important neo-classical economists employed more sophisticated psychological explanations,including Francis Edgeworth, Vilfredo Pareto and Irving Fisher. Economic psychology emerged in the 20th centuryin the works of Gabriel Tarde,[3] George Katona[4] and Laszlo Garai.[5] Expected utility and discounted utilitymodels began to gain acceptance, generating testable hypotheses about decision making given uncertainty andintertemporal consumption respectively. Observed and repeatable anomalies eventually challenged those hypotheses,and further steps were taken by the Nobel prizewinner Maurice Allais, for example in setting out the Allais paradox,a decision problem he first presented in 1953 which contradicts the expected utility hypothesis.

Daniel Kahneman

In the 1960s cognitive psychology began to shed more light on the brain asan information processing device (in contrast to behaviorist models).Psychologists in this field, such as Ward Edwards,[6] Amos Tversky andDaniel Kahneman began to compare their cognitive models ofdecision-making under risk and uncertainty to economic models of rationalbehavior. In mathematical psychology, there is a longstanding interest inthe transitivity of preference and what kind of measurement scale utilityconstitutes (Luce, 2000).[7]

Prospect theory

In 1979, Kahneman and Tversky wrote Prospect theory: An Analysis ofDecision Under Risk, an important paper that used cognitive psychology toexplain various divergences of economic decision making from

Page 87: Wikipedia Book Finance

Behavioral finance 84

neo-classical theory.[8] Prospect theory is an example of generalized expected utility theory. Although not aconventional part of behavioral economics, generalized expected utility theory is similarly motivated by concernsabout the descriptive inaccuracy of expected utility theory.In 1968 Nobel Laureate Gary Becker published Crime and Punishment: An Economic Approach, a seminal work thatfactored psychological elements into economic decision making. Becker, however, maintained strict consistency ofpreferences. Nobelist Herbert Simon developed the theory of Bounded Rationality to explain how people irrationallyseek satisfaction, instead of maximizing utility, as conventional economics presumed. Maurice Allais produced"Allais Paradox", a crucial challenge to expected utility.Psychological traits such as overconfidence, projection bias, and the effects of limited attention are now part of thetheory. Other developments include a conference at the University of Chicago,[9] a special behavioral economicsedition of the Quarterly Journal of Economics ('In Memory of Amos Tversky') and Kahneman's 2002 Nobel forhaving "integrated insights from psychological research into economic science, especially concerning humanjudgment and decision-making under uncertainty".[10]

Intertemporal choiceBehavioral economics has also been applied to intertemporal choice. Intertemporal choice behavior is largelyinconsistent, as exemplified by George Ainslie's hyperbolic discounting (1975) which is one of the prominentlystudied observations, further developed by David Laibson, Ted O'Donoghue, and Matthew Rabin. Hyperbolicdiscounting describes the tendency to discount outcomes in near future more than for outcomes in the far future. Thispattern of discounting is dynamically inconsistent (or time-inconsistent), and therefore inconsistent with basicmodels of rational choice, since the rate of discount between time t and t+1 will be low at time t-1, when t is the nearfuture, but high at time t when t is the present and time t+1 the near future.The pattern can actually be explained through models of subadditive discounting which distinguishes the delay andinterval of discounting: people are less patient (per-time-unit) over shorter intervals regardless of when they occur.Much of the recent work on intertemporal choice indicates that discounting is a constructed preference. Discountingis influenced greatly by expectations, framing, focus, thought listings, mood, sign, glucose levels, and the scales usedto describe what is discounted. Some prominent researchers question whether discounting, the major parameter ofintertemporal choice, actually describes what people do when they make choices with future consequences.Considering the variability of discount rates, this may be the case.

Other areas of researchOther branches of behavioral economics enrich the model of the utility function without implying inconsistency inpreferences. Ernst Fehr, Armin Falk, and Matthew Rabin studied "fairness", "inequity aversion", and "reciprocalaltruism", weakening the neoclassical assumption of "perfect selfishness." This work is particularly applicable towage setting. Work on "intrinsic motivation" by Gneezy and Rustichini and on "identity" by Akerlof and Krantonassumes agents derive utility from adopting personal and social norms in addition to conditional expected utility."Conditional expected utility" is a form of reasoning where the individual has an illusion of control, and calculatesthe probabilities of external events and hence utility as a function of their own action, even when they have no causalability to affect those external events.[11][12]

Behavioral economics caught on among the general public, with the success of books like Dan Ariely's PredictablyIrrational. Practitioners of the discipline have studied quasi-public policy topics such as broadband mapping.[13][14]

Behavioral finance 85

MethodologyBehavioral economics and finance theories developed almost exclusively from experimental observations and surveyresponses, although in more recent times real world data have taken a more prominent position. Functional magneticresonance imaging (fMRI) allows determination of which brain areas are active during economic decision making.Experiments simulating markets such as stock trading and auctions can isolate the effect of a particular bias uponbehavior. Such experiments can help narrow the range of plausible explanations. Good experiments areincentive-compatible, normally involving binding transactions and real money.

Behavioral economics vs experimental economicsNote that behavioral economics is distinct from experimental economics, which uses experimental methods to studyeconomic questions. Not all economics experiments are psychological. While many experimental economics studiesprobe psychological aspects of decision making, other experiments explore institutional features or serve as "betatesting" for new market mechanisms. Not all behavioral economics uses experiments, either; behavioral economistsrely heavily on theory and on observational studies "in the field."

Key observationsThree themes predominate in behavioral finance and economics:[15]

• Heuristics: People often make decisions based on approximate rules of thumb, not strict logic. See also cognitivebiases and bounded rationality.

• Framing: The collection of anecdotes and stereotypes that make up the mental emotional filters individuals relyon to understand and respond to events.

• Market inefficiencies: These include mis-pricings, non-rational decision making, and return anomalies. RichardThaler, in particular, has described specific market anomalies from a behavioral perspective.

Barberis, Shleifer, and Vishny[16] and Daniel, Hirshleifer, and Subrahmanyam (1998)[17] built models based onextrapolation (seeing patterns in random sequences) and overconfidence to explain security market under- andoverreactions, though their source continues to be debated. These models assume that errors or biases are positivelycorrelated across agents so that they do not cancel out in aggregate. This would be the case if a large fraction ofagents look at the same signal (such as the advice of an analyst) or have a common bias.More generally, cognitive biases may also have strong anomalous effects in the aggregate if there is social contagionof ideas and emotions (causing collective euphoria or fear) leading to phenomena such as herding and groupthink.Behavioral finance and economics rests as much on social psychology within large groups as on individualpsychology. In some behavioral models, a small deviant group can have substantial market-wide effects (e.g. Fehrand Schmidt, 1999).

TopicsModels in behavioral economics typically address a particular market anomaly and modify standard neo-classicalmodels by describing decision makers as using heuristics and subject to framing effects. In general, economicscontinues to sit within the neoclassical framework, though the standard assumption of rational behavior is oftenchallenged.

CriticismsCritics of behavioral economics typically stress the rationality of economic agents.[18] They contend thatexperimentally observed behavior has limited application to market situations, as learning opportunities andcompetition ensure at least a close approximation of rational behavior.Others note that cognitive theories, such as prospect theory, are models of decision making, not generalizedeconomic behavior, and are only applicable to the sort of once-off decision problems presented to experimentparticipants or survey respondents.Traditional economists are also skeptical of the experimental and survey-based techniques which behavioraleconomics uses extensively. Economists typically stress revealed preferences over stated preferences (from surveys)in the determination of economic value. Experiments and surveys are at risk of systemic biases, strategic behaviorand lack of incentive compatibility.Rabin (1998)[19] dismisses these criticisms, claiming that consistent results are typically obtained in multiple situations and geographies and can produce good theoretical insight. Behavioral economists have also responded to these criticisms by focusing on field studies rather than lab experiments. Some economists see a fundamental schism between experimental economics and behavioral economics, but prominent behavioral and experimental economists

Page 90: Wikipedia Book Finance

Behavioral finance 87

tend to share techniques and approaches in answering common questions. For example, behavioral economists areactively investigating neuroeconomics, which is entirely experimental and cannot be verified in the field.Other proponents of behavioral economics note that neoclassical models often fail to predict outcomes in real worldcontexts. Behavioral insights can influence neoclassical models. Behavioral economists note that these revisedmodels not only reach the same correct predictions as the traditional models, but also correctly predict someoutcomes where the traditional models failed.

Behavioral finance

TopicsThe central issue in behavioral finance is explaining why market participants make systematic errors. Such errorsaffect prices and returns, creating market inefficiencies. It also investigates how other participants arbitrage suchmarket inefficiencies.Behavioral finance highlights inefficiencies such as under- or over-reactions to information as causes of markettrends (and in extreme cases of bubbles and crashes). Such reactions have been attributed to limited investorattention, overconfidence, overoptimism, mimicry (herding instinct) and noise trading. Technical analysts considerbehavioral economics' academic cousin, behavioral finance, to be the theoretical basis for technical analysis.[20]

Other key observations include the asymmetry between decisions to acquire or keep resources, known as the "bird inthe bush" paradox, and loss aversion, the unwillingness to let go of a valued possession. Loss aversion appears tomanifest itself in investor behavior as a reluctance to sell shares or other equity, if doing so would result in a nominalloss.[21] It may also help explain why housing prices rarely/slowly decline to market clearing levels during periods oflow demand.Benartzi and Thaler (1995), applying a version of prospect theory, claim to have solved the equity premium puzzle,something conventional finance models have been unable to do so far.[22] Experimental finance applies theexperimental method, e.g. creating an artificial market by some kind of simulation software to study people'sdecision-making process and behavior in financial markets.

ModelsSome financial models used in money management and asset valuation incorporate behavioral finance parameters,for example:• Thaler's model of price reactions to information, with two phases, underreaction-adjustment-overreaction,

creating a price trendOne characteristic of overreaction is that average returns following announcements of good news is lower thanfollowing bad news. In other words, overreaction occurs if the market reacts too strongly or for too long tonews, thus requiring adjustment in the opposite direction. As a result, outperforming assets in one period arelikely to underperform in the following period.

• The stock image coefficient

CriticismsCritics such as Eugene Fama typically support the efficient-market hypothesis. They contend that behavioral finance is more a collection of anomalies than a true branch of finance and that these anomalies are either quickly priced out of the market or explained by appealing to market microstructure arguments. However, individual cognitive biases are distinct from social biases; the former can be averaged out by the market, while the other can create positive feedback loops that drive the market further and further from a "fair price" equilibrium. Similarly, for an anomaly to violate market efficiency, an investor must be able to trade against it and earn abnormal profits; this is not the case

Page 91: Wikipedia Book Finance

Behavioral finance 88

for many anomalies.[23]

A specific example of this criticism appears in some explanations of the equity premium puzzle. It is argued that thecause is entry barriers (both practical and psychological) and that returns between stocks and bonds should equalizeas electronic resources open up the stock market to more traders.[24] In reply, others contend that most personalinvestment funds are managed through superannuation funds, minimizing the effect of these putative entry barriers.In addition, professional investors and fund managers seem to hold more bonds than one would expect given returndifferentials.

QuantitativeQuantitative behavioral finance uses mathematical and statistical methodology to understand behavioral biases. Inmarketing research, a study shows little evidence that escalating biases impact marketing decisions.[25] Leadingcontributors include Gunduz Caginalp (Editor of the Journal of Behavioral Finance from 2001–2004) andcollaborators including 2002 Nobelist Vernon Smith, David Porter, Don Balenovich,[26] Vladimira Ilieva and AhmetDuran[27] and Ray Sturm.[28]

The research can be grouped into the following areas:1.1. Empirical studies that demonstrate significant deviations from classical theories2.2. Modeling using the concepts of behavioral effects together with the non-classical assumption of the finiteness of

assets3.3. Forecasting based on these methods4.4. Testing models against experimental asset markets

Behavioral game theoryBehavioral game theory is a subject that analyzes interactive strategic decisions and behavior using the methods ofgame theory,[29] experimental economics, and experimental psychology. Experiments include testing deviationsfrom typical simplifications of economic theory such as the independence axiom[30] and neglect of altruism,[31]

fairness,[32] and framing effects.[33] On the positive side, the method has been applied to interactive learning[34] andsocial preferences.[35][36] As a research program, the subject is a development of the last three decades.[37]

Economic reasoning in non-human animalsA handful of comparative psychologists at American universities have attempted to demonstrate economic reasoningin non-human animals. Early attempts along these lines focus on the behavior of rats and pigeons. These studiesdraw on the tenets of behavioral psychology, where the main goal is to discover analogs to human behavior inexperimentally-tractable non-human animals. They are also methodologically similar to the work of Ferster andSkinner [38]. Methodological similarities aside, early researchers in non-human economics deviate from behaviorismin their terminology. Although such studies are set up primarily in an operant conditioning chamber, using foodrewards for pecking/bar-pressing behavior, the researchers describe pecking and bar pressing not in terms ofreinforcement and stimulus-response relationships, but instead in terms of work, demand, budget, and labor. Recentstudies have adopted a slightly different approach, taking a more evolutionary perspective, comparing economicbehavior of humans to a species of non-human primate, the capuchin monkey[39].

The animal as a human analogMany early studies of non-human economic reasoning were performed on rats and pigeons in a operant conditioningchamber. These studies looked at things like peck rate (in the case of the pigeon) and bar pressing rate (in the case ofthe rat) given certain conditions of reward. Early researchers claim, for example, that response pattern (pecking/barpressing rate) is an appropriate analog to human labor supply [40]. Researchers in this field advocate for theappropriateness of using animal economic behavior to understand the elementary components of human economicbehavior [41]. In a paper by Battalio, Green, and Kagel (1981, p 621)[40], they write

“Space considerations do not permit a detailed discussion of the reasons why economists should take seriously the investigation of economictheories using nonhuman subjects....[Studies of economic behavior in non-human animals] provide a laboratory for identifying, testing, andbetter understanding general laws of economic behavior. Use of this laboratory is predicated on the fact that behavior as well as structure varycontinuously across species, and that principles of economic behavior would be unique among behavioral principles if they did not apply, withsome variation, of course, to the behavior of nonhumans. ”

Labor supplyThe typical laboratory environment to study labor supply in pigeons is set up as follows. Pigeons are first deprived offood. Since the animals are hungry, food becomes highly desired. The pigeons are placed in an operant conditioningchamber and through orienting and exploring the environment of the chamber they discover that by pecking a smalldisk located on one side of the chamber, food is delivered to them. In effect, pecking behavior becomes reinforced,as it is associated with food. Before long, the pigeon pecks at the disk (or stimulus) regularly.In this circumstance, The pigeon is said to "work" for the food by pecking. The food, then, is thought of as thecurrency. The value of the currency can be adjusted in a couple of different ways, including the amount of fooddelivered, the rate of food delivery and the type of food delivered (Some foods are more desirable than others).Economic behavior similar to that observed in humans is discovered when the hungry pigeons stop working/workless when the reward is reduced. Researchers argue that this is similar to labor supply behavior in humans. That islike humans (who, even in need, will only work so much for a given wage) the pigeons demonstrate decreases inpecking (work) when the reward (value) is reduced [40].

DemandIn human economics, a typical demand curve is negative. This means that as the price of a certain good increases, theamount that consumers are able to purchase decreases. Researchers studying demand curves in non-human animalssuch as rats observe that demand curves have negative slopes, consistent with the slope of human demand curves.Researchers have studied demand in rats in a manner distinct from studying labor supply in pigeons. Specifically,say we have experimental subjects, rats, in an operant chamber and we require them to press a lever to receive areward. The reward can be either food (reward pellets), water, or a commodity drink such as cherry cola. Unlikeprevious pigeon studies, where the work analog was pecking and the monetary analog was reward, in the studies ondemand in rats, the monetary analog is bar pressing. Under these circumstances, the researchers claim that changingthe number of bar presses required to obtain a commodity item is analogous to changing the price of a commodityitem in human economics [42].In effect, results of demand studies in non-human animals are that, as the bar-pressing requirement (cost) increases,the animal presses the bar the required number of times less often (payment).

Monkey trading behaviorRecent work on economic behavior in non-human animals has focused on capuchin monkeys. Here the researchersseem less inclined toward the behaviorist tradition of the laboratory animal-human behavior analog. Instead, theyattempt to adopt a more evolutionary perspective, positing that economic reasoning might be basic, unlearned, andserve some adaptive function.One recent study [39]involves the introduction of a currency system into a colony of captive capuchin monkeys. Thecurrency is in the form of coins and is redeemable for food and other purchasable items when exchanged with aresearcher. Under these conditions, the researchers studied three features of monkey trading: demand, loss aversion,and risk aversion.In this study, monkeys are presented with an amount of money and are shown a certain amount of food or othergoods. The monkeys must take the money and hand it to the experimenter in exchange for goods. In one condition ofthe experiment, after the monkey has paid for the goods, it has the option to take a sure amount of food now, or waituntil the experimenter alters the amount of food presented. In this circumstance, the experimenter can either increaseor decrease the amount of food given. Thus, this experimental setup allows the researchers to look at the gamblingbehavior of the animals. The experimenters can therefore ask the following questions: Will the monkey take the sureamount of food? Will the monkey “gamble” by waiting until the experimenter changes the amount of food present?Does the decision of the animal depend on the circumstances? Results indicate that the monkeys are risk-averse:They prefer to take the initial amount of food than wait for the experimenter to change the amount presented.The experimenters introduce several other manipulations, including changing the allocated budget, changing the costof certain items, changing the items themselves. Specifically, the researchers found an increase in item purchase andconsumption when that item decreases in value, a result consistent with those found in human economics[39].Taken together, the results of this study indicate that capuchin monkeys are not only risk-averse, but are alsosensitive to constructs such as price, budget, and payoff expectation. According to the researchers, the animals arenot trained to behave in this way; these behaviors arise naturally in the trading environment. As a result, theseresearchers argue that basic economic behavior and reasoning might be unlearned, innate, and subject to naturalselection.

Intangible asset finance

Intangible asset financeIntangible Asset Finance is the branch of finance that deals with intangible assets such as patents (legal intangible)and reputation (competitive intangible). Like other areas of finance, intangible asset finance is concerned with theinterdependence of value, risk, and time.

Basic principlesIn 2003, one estimate put the economic equilibrium of intangible assets in the U.S. economy at $5 trillion, whichrepresented over one-third or more of the value of U.S. domestic corporations in the first quarter of 2001.[1]

One of the goals of people working in this field is to unlock the "hidden value" found in intangible assets through thetechniques of finance. Another goal is to measure how firm performance correlates with intangible assetmanagement.Intangible assets include business processes, Intellectual Property (IP) such as patents, trademarks, reputations forethics and integrity, quality, safety, sustainability, security, and resilience. Today, these intangibles drive cash flowand are the primary sources of risk. Intangible asset information, management, risk forecasting and risk transfer aregrowing services as the economic base divests itself of physical assets.

Business modelsA number of intangible asset business models have evolved over the years.• Patent Licensing & Enforcement Companies ("P-LECs"): These are firms that acquire patents for the sole

purpose of securing licenses and/or damages awards from infringing parties. Perhaps the most famous P-LEC isNTP, Inc., which has successfully asserted patents related to email push technology. Another name for a P-LEC is"patent troll," although this is viewed as a pejorative reference. Recently, hedge funds have raised capital for thespecific purpose of investing in patent litigation. One such hedge fund is Altitude Capital Partners, which is basedin New York.

• Royalty stream securitizers: These are firms that are engaged in the buying and selling of what are essentiallyspecialized asset-backed securities. The assets that are securitized are typically intellectual properties, such aspatents, that have been bearing royalties for a period of time. Royalty Pharma is a well known firm that uses thisbusiness model, and which has done by far the largest and most high-profile deals in this space.[2] RoyaltyPharma handled what many consider to be the first pharmaceutical patent-backed securitization to be rated byStandard and Poors, which involved a patent on the HIV drug Zerit.[3] The other parties involved in the Zerittransaction were Yale (the owner of the patent) and Bristol Myers Squibb.

• Reinsurers: These are firms that use the techniques of reinsurance to mitigate intangible asset risks. In the sameway that some firms issue Cat bonds to mitigate the risks associated with extreme weather, earthquakes, or othernatural disasters, firms exposed to substantial intangible risk can issue "intangible asset risk-linked securities" thattransfer intangible risk to hedge funds and other players in the capital markets with a sufficient appetite for risk.Steel City Re, which is based in Pittsburgh, is a thought leader regarding the use of risk transfer techniques toprotect and recover intangible asset value.[4]

• Market makers: Firms that are working to provide more liquidity to the market for intellectual property. Early market makers offered on-line intellectual property exchanges where buyers and sellers could exchange rights in

licensed intellectual property, usually patents. On April 22, 2008, Ocean Tomo reported[5] that it had transactedapproximately $70 million in its IP auctions across Europe and the United States. In 2009, The IntellectualProperty Exchange International (IPXI), headquartered in Chicago, will begin operations as the world’s first stockexchange with an intellectual property focus.

• Investment Research Firms: Companies that provide specific advice to investors on intellectual property issues.Recently, hedge fund managers have been hiring patent attorneys to follow and handicap outcomes in high stakespatent cases. IPD Analytics, which is based in Miami, is known for is research reports on patent litigation pendingin the United States district court as well at the United States Court of Appeals for the Federal Circuit.

Significant transactions• 1997: David Bowie securitizes the future royalty revenues earned from his pre-1990 music catalogue by issuing

Bowie Bonds.• 2000: BioPharma Royalty Trust completes the $115 million securitization of a single Yale patent with claims

covering Stavudine, which is a reverse transcriptase inhibitor and the active ingredient in the drug Zerit.
