MONEY

Money is anything that is in general use in the purchase of goods and services and in the discharge of debts. Money may also be defined as an evidence of debt owed by society. The money supply in the US consists of currency (paper money), coins, and demand deposits (checking accounts). Currency and coins are government-created money, whereas demand deposits are bank-created money. Of these three components of the money supply, demand deposits are by far the most important. Thus, most of the money supply is invisible, intangible, and abstract.

The two most important inherent attributes that money must possess in a modern credit economy are acceptability and stability. In earlier times in the evolution of money and monetary institutions in the United States, the attributes of divisibility, portability, and visibility were important. The two legal attributes of 'legal tender' and 'standard money' are not of as much importance today as in the past.

The four functions that money often performs are (1) standard of value, (2) medium of exchange, (3) store of value, and (4) standard of deferred payment. In a modern specialized economy, (2) and, most especially, (1) are the most important of these.

Although it is agreed that the value of money has fallen in the US over time, there are three in part conflicting theories of value that have been advanced to explain this phenomenon: the commodity, quantity, and income theories. Most economists today espouse either the second or, more typically, the third of these. Any money can retain its value as long as its issuance is limited; it need not have a commodity backing. Inflation or rising prices have been explained by demand and/or supply theories in recent years, although historically the former has been thought to provide the more satisfactory explanation.

All values in the economic system are measured in terms of money. Our goods and services are sold for money, and that money is in turn exchanged for other goods and services. Coins are adequate for small transactions, while paper notes are used for general business. There is additionally a wider sense of the word 'money', covering anything, which is used as a means of exchange, whatever form it may take. Originally, a valuable metal (gold, silver or copper) served as a constant store of value, and even today the American dollar is technically 'backed' by the store of gold which the US government maintains. Because gold has been universally regarded as a very valuable metal, national currencies were for many years judged in terms of the so-called 'gold standard'.

Nowadays however valuable metal has generally been replaced by paper notes. National currencies are considered to be as strong as the national economies, which support them. Paper notes are issued by governments and authorized banks, and are known as 'legal tender'.

The value of money is basically its value as a medium of exchange, or as economists put it, its 'purchasing power'. This purchasing power is dependent on supply and demand. If too much money is available, its value decreases, and it does not buy as much as it did, say five years earlier. This condition is known as 'inflation'.
