Money: Functions of Money

The Four Jobs of Money• Medium of exchange

• Standard of value/Unit of account• Store of value

• Standard of deferredpayments

• Medium of exchange• The most important job of money is to serve

as a medium of exchange– When any good or service is purchased, people

use money– Money makes it easier to buy and sell because

money is universally accepted– Money, then, provides us with a shortcut in

doing business• By acting as a medium of exchange, money

performs its most important function

Money versus Barter

• • Without money, the only way to do

business is by bartering

• For barter to work, I must want what you

have and you must want what I have• – This makes it pretty difficult to do business

• • “Everything, then, must be assessed in• money: for this enables men always to• exchange their services, and so makes• society possible”• – Aristotle, Nicomachean Ethics

Shows no coincidence of needs and no barter is going on

Money as a Medium ofExchange

• Money facilitates exchange by reducing

the cost of trading.• Without money, we would have to

barter.

Money As a Medium ofExchange

• Money does not have to have anyinherent value/usefulness to function as a medium of exchange.• All that is necessary is that everyonebelieves that other people will exchange it for other goods/services

Standard of Value• Money is a common denominator

in which the relative value ofgoods and services can be

expressed– A job that pays Rs 2 an hour would be

nearly impossible to fill, while one payingRS 50 an hour would be swamped with

applications

Money as a Unit ofAccount

• Money is used as a common denominator tomeasure the relative values of goods and

services.• Without money, we would have to measure

the value of goods and services in terms ofother goods and services.

• Money is a useful unit of account only if itsvalue relative to the average of all other

prices doesn’t change too quickly.

Store of Value• If you could buy 100 units of goods and services with $100 in 1982, how many units could you buy with $100 in 2000? – Answer: you could have bought just 51 units – During this period, inflation robbed the dollar of almost half of its purchasing power• Over the long run, particularly since World War II, money has been a very poor store of value• – However, over relatively short periods of time, say, a few weeks or months, money does not lose much of its value

Money as a Store of Value

• Money is a financial asset that can be used to store wealth (income that youhave saved and not consumed).• As a store of wealth, money pays no interest, but is perfectly liquid.• Money’s usefulness as a store of wealth depends on how will it maintains its value.

Standard of Deferred Payment

• • Many contracts promise to pay fixed sums of money well into the future– A couple of examples are 30-year corporate bonds and a 20-year mortgage

Standard of Deferred Payment

You have taken education loan or housing loan say Rs 20 lakhs to repay in installments after two/three years with interests

Hosing loan is for longer terms and EMI is fixed.Any way , most of the durable consumer goods

are purchased with loans which are paid afterwards / in instalments.

These are possible as settlement is done through money

Standard of Deferred Payment

• How well does money do its job as astandard of deferred payment?– About as well as it does as a store ofvalue– Usually quite well in the short run, butnot well at all over the long run of, say,three years or more

• Money versus Barter• • Without money, the only way to do• business is by bartering• • For barter to work, I must want what you• have and you must want what I have• – This makes it pretty difficult to do business

• • “Everything, then, must be assessed in• money: for this enables men always to• exchange their services, and so makes• society possible”• – Aristotle, Nicomachean Ethics

Monetary Standards: Fiat vs Commodity Money

Fiat Money System:• Circulating money is paper money with low

cost of production and low value in non-monetary uses.

• The quantity of fiat money is controlled by the monetary authority in the economy as to keep the purchasing power of a unit of money very high relative to its cost of production.

Money - Prices and Interest rate

• Classical Economists such as Irving Fisher holds that there is proportional relation between Money supply and the Price level

• This is explained on the basis of the following assumptions• Economy is always at the full employment and Aggr.

Output is fixed at full employment level of output• Velocity of circulation of money is fixed as this is

determined on the basis of payment habits, liquidity preference, propensity to consume and development of the banking and credit institutions which do change slowly

• Classical theory express this relation in the following identity

• MV= PT

• V= PT/M• P=M/PT• Modern Quantity theory• States that growth of money supply determines

the nominal GDP and hence the nominal aggr. Demand through which prices are influenced

• Hence targeting Money supply is essential In the Economy. Here monetary policy is important to regulate the economy.

Keynesian liquidity preference theory of money

• Keynesian theory does not believe that the economy remains always at full employment level. There could be involuntary unemployment in the economy due to lack of aggr. demand.

Price level

• Keynesian economy also does not believe that velocity of circulation of money is constant

• Hence Keynesian economy challenges the direct and proportional relationship between money supply and the price level.

• It shows that increase in money supply and hence aggregate nominal demand may not always increase price level :

When the economy is operating at unemployment equilibrium.

Money market: Keynesian demand for money

• According to Keynes Money is demanded by public for three motives:

• 1. Transaction• 2.Precautionary motives• 3.Speculative motives• Both Transaction and precautionary demands

for money are depended on the level of income and it is positively related

• Speculative demand for money is money demand as an asset

• There are other financial assets: Bonds, debenture, Govt. Securities, Corporate securities, Stocks etc.

• Difference between Money and other financial assets

• Money: most liquid• Holding money is riskless• But money is non income earning asset

• Other financial assets have less liquidity but they yield income

• Speculator wants money to buy other non money financial assets at a low price and sell them at a higher price and the difference between buying and selling prices are their incomes from trading financial assets.

• Bond price i.e. price of fin asset is inverse related to the interest rate.

• let the market rate of interest is 5%• If you hold cash of Rs. 95 for a year, you forego

interest income at the rate of 5%. • If you invest on a bond then you get Rs. 95(1+.o5)

=99.75 Hence Pv.of Bond= Rs.100/1+0.05= Rs. 95 present value

of bond1+0.05=95/100=.951+r= .95 r =1- .95=.05

• When interest rate is 10%• Present value of bond yielding Rs 100 is• PV= 100/1+10% • =100/1.1=90• Bond price is nothing but the present value of

bond at a given rate of interest.• Let Bv is the future yield from the bond then • Bp= Br/1+r

• thus demand for real balance or liquidity ( L) has two components Ld= transaction and precautionary demand

which depend income and positively related. Ls= which depends on interest rate and

inversely related

A contraction in the money supply raises the interest rate that equilibratesthe money market. Why? Because a higher interest rate is needed to convince people to hold a smaller quantity of real balances.As a result of the decrease in the money supply, LM shifts upward.

Bank created Money Supply

Groups involved in creation of Bank money1. Commercial banks2. Depositors3. Borrowers4. Central Bank: RBI

Let us think that there are individual BanksA, B, C, D, E, and so on• Let a depositor open deposit of Rs 100 with

bank A• This bank (A) opens and IOU for the depositor• This is its liability• Then the bank also has the asset in terms of

cash

• Bank A will not keep the money reserve• It will give loan to the public . This is how bank does

the business• They take deposits from the public with the

promise of paying interest • Banks give loan to the public from the deposit

money to earn interest income• Difference between credit interest earnin gand

deposit interest cost is the profit of the bank on which banking business is based.

What is fractional Reserve System

• Commercial banks are legally bound to keep some per cent of deposit as reserve cash

• This reserve ratio is fixed by the central bank• This done in order to meet the cash

withdrawal by the depositor• Reserve cash enables the banks ensure

confidence

Money multiplier• Money multiplier• The expansion of Rs100 through fractional-reserve banking with varying

reserve requirements. Each curve approaches a limit. This limit is the value that the money multiplier calculates.

• The most common mechanism used to measure this increase in the money supply is typically called the money multiplier. It calculates the maximum amount of money that an initial deposit can be expanded to with a given reserve ratio.

• Formula• The money multiplier, m, is the inverse of the reserve requirement, R:[

• Example• For example, with the reserve ratio of 20 percent, this reserve ratio, R, can

also be expressed as a fraction:• So then the money multiplier, m, will be calculated as: 1/5• This number is multiplied by the initial deposit to show the maximum

amount of money it can be expanded to.
