What is Money?
Characteristics
1. Medium of exchange Buying and selling goods and services
2. Unit of account Assisting measurement of relative worth of various goods,
services and resources
3. Store of value A form in which to store wealth, due to its liquidity and
convenience Standard of deferred payment (e.g. wages)
Money Supply
Most economies classify their money supply according to the following definitions:
M1; M2; M3; and Broad Money.
The Money Market
Three components of the money supply are of significance:
Currency (coins and notes) in hands of non-bank public
Current deposits in banks upon which cheques can be drawn
Non-current accounts such as savings accounts and term deposits with banks.
The Money Market
The Money Market
Currency Coin and note component of the money
supply In modern economies, currency has not real
value of itself – it has legal backing by the government that makes it acceptable as a means of payment.
Current Deposits Can be readily converted into currency Generally acceptable as a medium of
exchange Cheques enable the ownership of current
deposits to be transferred
The Money Market
Non-current Deposits Can be readily converted into currency or
current deposits Highly liquid financial assets New technologies (such as EFTPOS)
important
The Money Market
M1 total of currency outside banks and demand deposits
(non-interest-bearing chequing accounts). M1 definition is the most liquid of all assets and is the traditional definition of money supply.
M2 adds to M1 assets such as savings accounts, small
denomination time deposits, money market deposit accounts, and money market mutual fund shares. (US Federal Reserve uses this definition.)
The Money Market
M3 M1 and M2 plus assets as large denomination time
deposits. M3 is the sum of currency (notes and coins), current (or demand) deposits in banks on which cheques can be drawn, and non current deposits in banks (e.g. savings) (commonly used by RBA, although RBA uses other definition such as Broad Money)
Broad money M3 plus borrowings from the private sector of non-bank
financial intermediaries (NBFIs) less holdings of currency and bank deposits by the NBFIs

The Money Market
Credit Cards Not money Simply a convenient method of obtaining a
short-term loan from the card-issuer Facilitate the synchronisation of receipts and
expenditures, reducing the demand for cash
The Money Market
Money Demand
The demand for money is the demand for real money balance
2 reasons why people demand money:
1. Transactions demand
2. Asset demand
The Money Market
Transactions Demand
The demand for money as a medium of exchange (to buy goods and services)
Depends on money GDP (not interest rates)
Vertical demand curve.
The Money Market
Asset DemandThe demand for money as a financial asset and store of wealth
The interest rate reflects the opportunity cost of holding money:
The lower the interest rate in the economy, the lower the opportunity cost of holding money & more willing to hold money for its liquidity. The higher the interest rate, the greater the cost of holding money (in interest rate forgone) & so will hold less money.
Downward-sloping asset money demand curve

Total Demand for Money Transactions demand and assets demand
are added horizontally
DM=MDt+MDa
Changes in interest rates lead to movement along the curve
Anything that changes money GDP leads to a shift in the money demand curve

The Financial Sector
Some Basic DefinitionsBank: an institution that takes funds from one group of investors and re-deploys those funds by investing in financial assets.
Non-bank Financial Institution (NBFI): permanent building societies, credit cooperatives, money market corporations (merchant banks), pastoral finance companies, finance companies, general financiers, insurance companies and cash management trusts.
Deposit: funds placed into a bank account Current deposit: no minimum term requirement Non-current Deposit: minimum term bank deposit
Loan: repayable funds given out by a bank for a specific period of time
Reserves: currency held by private banks to meet operating requirements.
A bank uses its reserves to meet depositors’ demand for currency and to make payments to other banks. A bank’s reserves are made up of: Actual reserves: how much reserves a bank holds. Desired Reserves: the reserves that a bank wishes to
hold. Excess reserves: how much reserves a bank can loan
out. actual reserves minus desired reserves.

Some Basic DefinitionsCentral Bank: regulates an economy’s financial sector and implements Monetary Policy.
Some basic definitions:
Liquidity : ability to convert an asset into cash quickly with little loss in value.
Bond: liability issued by a government or a business (corporate bond) promising to pay the holder a fixed cash amount at a specified maturity date and usually to make regular interest payments in the interim.
Securities: financial instruments representing ownership or debt, such as stocks and bonds, that provide claims to future expected cash flows.
The Role of Banks
Economic Functions of Banks Create Liquidity Minimise the cost of obtaining funds Minimise the cost of monitoring borrowers Pool Risk.
Banks and Financial Instability
Banks may contribute to business fluctuations Can exacerbate recession, by holding back
on credit expansion May amplify inflationary pressures, by
increasing lending and credit creation
A Bank’s Balance Sheet
A statement of assets and claims that summarises the financial position of a firm at a point in time
Each side balances: Assets are items of economic and financial value.
Example, loans, reserves. Liabilities are claims of other parties on the bank.
Example, deposits
Assets = Liabilities + Owners’ Equity

Creating Money
The Banking System
Multiple banks: multiple-deposit expansion Money is created by a multiple of the banking
system’s excess reservesAssume reserve ratio is 20%
Bank must keep $20 000 (required reserves)
Reserve Ratio = Bank’s Required Reserves
Bank’s Deposit Liabilities
Multiple-Deposit Expansion Assume initially: 20% reserve requirement Bank A
Accepts a deposit for $100 Gains $100 in Actual Reserves and Deposits

Possible Leakages
Currency drains Loan may be paid in cash and remain in circulation
Transfer of deposits to non-bank financial institutions
Excess reserves Individual banks may choose to have larger reserves than
required (say 25% instead of 20%)
Willingness to Borrow
For the full multiplier effect to take place: Borrowers must be willing and able to utilise the
loans Borrowing is likely to be low during a recession
Monetary base & money creation
We saw that the tax refund cheque started the process of multiple deposit expansion for the banking system.
The monetary base is important. How can the government or RBA increase the
monetary base? by running deficits; by tax refund cheques; by buying government bonds from public; by purchasing foreign currencies.
Jackson and McIver, chs 9 and 10.
