Money
Money
is any good that is widely used and accepted in transactions involving the
transfer of goods and services from one person to another. Economists
differentiate among three different types of money commodity money,
fiat money, and bank money.
Commodity
money is a good whose value serves as the
value of money. Gold coins are an example of commodity money. In most
countries, commodity money has been replaced with fiat money.

Fiat
money is a good, the value of which is less
than the value it represents as money. Dollar bills are an example of fiat
money because their value as slips of printed paper is less than their value
as money.
|
Bank
money consists of the book credit
that banks extend to their depositors. Transactions made using checks
drawn on deposits held at banks involve the use of bank money.

Function of Money
Medium of exchange
Money
also acts as a medium of exchange or as a medium of payments. This function of
money is served by anything that facilitates trade by being generally accepted
by people in exchange for goods and services.
For example: pay for school
fees, food, daily expenses, and insurance. Money will then reduce the time and
energy spent in barter. The person who owned a cow can now simply sell it to
the person who offers the most money for it and then buy the bullock cart from
another person who offers him the best bargain. All trade may be considered
barter, one good or services is traded for another good or service either directly,
or indirectly with money acting as the intermediary. However, this function can
only be performed properly if the value of money remains constant.
Unit of account
Money
also functions as a unit of account, providing a common measure of the value of
goods and services being exchanged. Knowing the value or price of a good, in
terms of money, enables both the supplier and the purchaser of the good to make
decisions about how much of the good to supply and how much of good to
purchase.
Store of value
Money
as a store of value that refers to money as an asset that holder of money used
it to transporting purchasing power from one time period to another. Therefore,
it serves as a store of wealth over time when it retains purchasing power and
hold value over time. They keep money for investment. This function will be
performed well as long as money retains a constant purchasing power.
Standard of deferred
payment
Money
allows existence of credit, possible for contract be agreed involving payment
in the future. Examples of situations where future payments are to be made are
pensions, principal and interest on debt and salaries. As long as money maintains a constant value
through time, it will overcome the problems associated with making future
payments with specific commodities.
Motive of holding Money
Transaction motives:
The transactions motive
for demanding money arises from the fact that most transactions involve an
exchange of money. Because it is necessary to have money available for
transactions, money will be demanded. The total number of transactions made in
an economy tends to increase over time as income rises. Hence, as income or GDP
rises, the transactions demand for money also rises.
Precautionary motives:
People often demand money as a precaution
against an uncertain future. Unexpected expenses, such as medical or car repair
bills, often require immediate payment. The need to have money
available in such situations is referred to as the precautionary motive
for demanding money. We also hold money in case we need
to spend it.
Speculative motives:
Money, like other stores of value, is
an asset. The demand for an asset depends on both its rate of return
and its opportunity cost. Typically, money holdings provide no
rate of return and often depreciate in value due to inflation. The speculative
motive for demanding money arises in situations where holding money is
perceived to be less risky than the alternative of lending the money
or investing it in some other asset. The presence of a
speculative motive for demanding money is also affected by expectations of
future interest rates and inflation. If interest rates are expected to
rise, the opportunity cost of holding money will become greater.
Money
multiplier
The money multiplier is a
measure of the extent to which the creation of money in the banking system
causes the growth in the money supply
to exceed growth in the monetary base.
A money multiplier is one of
various closely related ratios of commercial bank money
to central bank money
under a fractional-reserve banking
system. Most often, it measures the maximum
amount of commercial bank money that can be created by a given unit of central
bank money. That is, in a fractional-reserve banking system, the total amount
of loans that commercial banks are allowed to extend is a multiple of reserves;
this multiple is the reciprocal
of the reserve
ratio, and it is an economic multiplier.
Function of Central bank
1.
Supervision of the banking system:
Central
bank supervises the banking system of the country. Central may be responsible
for banking system. They collect information from commercial bank and take necessary
decision by two ways:
a.)
bank examine
b.)
bank regulation
2.
Advising the government on monetary policy:
The
decision on monetary policy may be taken by the central bank. Monetary policy
refers to interest rates and money supply. The central bank will corporate with
the government on economic policy generally and will produce advice on monetary
policy and economic matters, including all the statistics.
3.
Issue of banknotes:
The
central bank controls the issue of banknotes and coins. Most payment these days
does not involve cash but cheques, standing order, direct debit, credit cards and
so on. Nevertheless, cash is important as bank’s cash holdings are a constraint
on creation of credit, as we have seen.
4.
Acting as banker to government:
Normally
a central bank acts as the government’s banker. It receives revenues for Taxes
and other income and pay out money for t6he government’s expenditure. Usually,
it will not lend to the government but will help the government to borrow money
by the sales of its bill and bonds.
How
Central Bank control money supply
Required
Reserve ratio
Required reserves are the
percentages of deposit bank hold in cash or a deposit of Fed. If the reserve
ratio decreases, the money supply increases and if the reserve ratio increase,
the money supply decrease. The Fed can
lower required reserve rate which raises the multiplier effect of high powered
money.
For example,
it the required reserves went from 20% to 10%, the bank would only need to hold
$10,000 in reserves for the initial injection of $100,000. The other $90,000
would be loaned out so at each stage in the multiplier chain, the banks would
be loaning out more funds and the eventual increase in the money supply would
be larger.
Discount
Rate
The discount rate is the interest rate at
which the Fed lends reserves to other banks. The Fed can lower the discount
rate and lower the costs for banks holding low excess reserves which will lower
the excess reserve rate. If discount rate increases, the supply of money will
decrease and if the discount rate decreases, the supply of money will increase.
Open
Market operations
Open market operations refer to the buying
and selling of government bonds in order to change the supply of money. If the
Fed sells bonds, the money supply decrease and if the Fed purchases bonds in
the open market, increase the money supply by the price of the bonds. The Fed
can buy or sell government securities.
For example,
the Fed will contact its broker and announce it wants to buy $100,000 of
government securities. The increase of $100,000 cash into the system will
result in an increase in the money supply of $500,000.
