Money is any object or record that is generally accepted as payment for goods
and services and repayment of debts in a given country or socio-economic context.
The exchange of goods and services in markets is among the most universal activities
of human life. To facilitate these exchanges, people settle on something that will
serve as a medium of exchange—they select something to be money.
However, this has not always been true. In primitive societies a system of
barter was used. Barter was a system of direct exchange of goods. Somebody could
exchange a sheep, for example, for anything in the market place that they considered
to be of equal value. Barter, however, was a very unsatisfactory system because
people’s precise needs seldom coincided. People needed a more practical system of
exchange, and various money systems developed based on goods which the members
of a society recognized as having value. Cattle, grain, teeth, shells, feather, salt,
tobacco have been used. Precious metals gradually took over because, when made
into coins, they were portable, durable, recognizable and divisible into larger and
smaller units of value.
The main functions of money are distinguished as: a medium of exchange; a
unit of account; a store of value; and, occasionally in the past, a standard of deferred
payment. When money is used to intermediate the exchange of goods and services, it
is performing a function as a medium of exchange. It thereby avoids the
inefficiencies of a barter system, such as the ‘double coincidence of wants’ problem.
Money also serves as a unit of account. A unit of account is a standard
numerical unit of measurement of the market value of goods, services, and other
transactions. Also known as a “measure” or “standard” of relative worth and deferred
payment, a unit of account is a necessary prerequisite for the formulation of
commercial agreements that involve debt.
The third function of money is to serve as a store of value, that is, an item that
holds value over time. To act as a store of value, money must be able to be reliably
saved, stored, and retrieved – and be predictably usable as a medium of exchange
when it is retrieved. The value of the money must also remain stable over time.
Money, of course, is not the only thing that stores value. Houses, office buildings,
land, works of art, and many other commodities are regarded as a means of storing
wealth and value. Money differs from these other stores of value as it is readily
exchangeable for other commodities. Its role as a medium of exchange makes it a
convenient store of value.
Because money acts as a store of value, it can be used as a standard for future
payments. When you borrow money, for example, you typically sign a contract
pledging to make a series of future payments to settle the debt. These payments will
be made using money, because money acts as a store of value.
The money supply of a country consists of currency (banknotes and coins) and
usually includes bank money (the balance held in checking accounts and savings
accounts). Bank money, which consists only of records (mostly computerized in
modern banking), forms by far the largest part of broad money in developed
countries.
