The Evolution Money

Money, term that actually refers to two concepts: the abstract unit of account in terms of which the value of goods, services, and obligations can be compared; and anything that is widely established as a means of payment. Frequently the standard of value also serves as a medium of exchange, but that is not always the case.

Evolution

Many ancient communities, for instance, took cattle as their standard of value but used more manageable objects as means of payment. Exchange involving the use of money is a great improvement over barter, since it permits elaborate specialization and provides generalized purchasing power that the participants in the exchange may use in the future. The growth of monetary institutions has largely paralleled that of trade and industry; today almost all economic activity is concerned with the making and spending of money incomes.

From the earliest times precious metals have had wide monetary use, owing to convenience of handling, durability, divisibility, and the high intrinsic value commonly attached to them. Whether an article is to be regarded as money does not, however, depend on its value as a commodity, except where intrinsic worth is necessary to make it generally acceptable in exchange; the relation between the face value of an object used as money and its commodity value has actually become increasingly remote (see coin).

Paper currency first appeared about 300 years ago; it was usually backed by some "standard" commodity of intrinsic value into which it could be freely converted on demand, but even during the early development of currency, issuance of inconvertible paper money, also called fiat money, was not infrequent (see, for example, Law, John). The world's first durable plastic currency was introduced by Australia in a special issue in 1988 and in a regular issue in 1992. Plastic bills are more resistant to counterfeiting than paper, and a number of countries now issue some plastic currency.

The importance of money has been variously interpreted. While the advocates of mercantilism tended to identify money with wealth, the classical economists, e.g., John Stuart Mill, usually considered money as a veil obscuring real economic phenomena. Since the mid-20th cent., a group known as the monetarists has given increasing attention to the role of money in determining national income and economic fluctuations.

Commodity accepted by general consent as a medium of economic exchange. It is the medium in which prices and values are expressed; it circulates from person to person and country to country, thus facilitating trade. Throughout history various commodities have been used as money, including seashells, beads, and cattle, but since the 17th century the most common forms have been metal coins, paper notes, and bookkeeping entries. In standard economic theory, money is held to have four functions: to serve as a medium of exchange universally accepted in return for goods and services; to act as a measure of value, making possible the operation of the price system and the calculation of cost, profit, and loss; to serve as a standard of deferred payments, the unit in which loans are made and future transactions are fixed; and to provide a means of storing wealth not immediately required for use.

Metals, especially gold and silver, have been used for money for at least 4,000 years; standardized coins have been minted for perhaps 2,600 years. In the late 18th and early 19th century, banks began to issue notes redeemable in gold or silver, which became the principal money of industrial economies.

Temporarily during World War I and permanently from the 1930s, most nations abandoned the gold standard. To most individuals today, money consists of coins, notes, and bank deposits. In terms of the economy, however, the total money supply is several times as large as the sum total of individual money holdings so defined, since most of the deposits placed in banks are loaned out, thus multiplying the money supply several times over.
