Money, Money, Money


Why is money important to us? Why do we need these things? You will find out after you read this post.
Economics offers various definitions for money, though it is now commonly defined as any good or token that functions as a medium of exchange that is socially and legally accepted in payment for goods and services and in settlement of debts. Money also serves as a standard of value for measuring the relative worth of different goods and services. Some authors explicitly require money to be a standard of deferred payment.[1] In common usage, money refers more specifically to currency, particularly the many circulating currencies with legal tender status conferred by a national state; deposit accounts denominated in such currencies are also considered part of the money supply, although these characteristics are historically comparatively recent. Money may also serve as a means of rationing access to scarce resources and as a quantitative measure that provides a common standard for the comparison and valuation of quality as well as quantity, such as in the valuation of real estate or artistic works. The use of money provides an easier alternative to barter, which is considered in a modern, complex economy to be inefficient because it requires a coincidence of wants between traders, and an agreement that these needs are of equal value, before a transaction can occur. The efficiency gains through the use of money are thought to encourage trade and the division of labour, in turn increasing productivity and wealth.
The value of money depends on what it can purchase, not what it is made of. Fiat money has value because it can be utilized to purchase goods and services, even though it has very little intrinsic value or utility other than as a medium of exchange. It is more difficult to concede that the same is true of gold and silver. While their intrinsic value remains unaltered by the quantity available, their value as a medium of exchange is directly depend on the availability of goods and services for sale. This is illustrated by the fact that when huge quantities of gold and even larger amounts of silver were discovered in the New World and brought back to Europe for conversion into coin, the purchasing power of those coins fell by 60% to 80%, i.e. prices of commodities rose, because the supply of goods for sale did not keep pace with the increased supply of money.[2] In addition, the relative value of silver to gold shifted dramatically downward.[3] Today's national currencies are backed by the governments that issue them, not by gold or silver, and the governments are backed by the productive capacity of the societies they represent. Money is one of the most central topics studied in economics and forms its most cogent link to finance. Monetarism is an economic theory which predominantly deals with the supply and demand for money. The stability of the demand for money prior to the 1980s was a key finding of the work of Milton Friedman, Anna Schwartz, David Laidler, and many others. Technical, institutional, and legal changes changed the nature of the demand for money during the 1980s. Monetary policy aims to manage the money supply, inflation and interest to affect output and employment. Inflation is the decrease in the value of a specific currency over time and can be caused by dramatic increases in the money supply. The interest rate, the cost of borrowing money, is an important tool used to control inflation and economic growth in monetary economics. Central banks are often made responsible for monitoring and controlling the money supply, interest rates and banking. A monetary crisis can have very significant economic effects, particularly if it leads to monetary failure and the adoption of a much less efficient barter economy. This happened in Russia, for instance, after the fall of the Soviet Union. There have been many historical arguments regarding the combination of money's functions, some arguing that they need more separation and that a single unit is insufficient to deal with them all. Financial capital is a more general and inclusive term for all liquid instruments, whether or not they are a uniformly recognized tender.
