Monetary policy

Monetary policy is the process by which a government, central bank, or monetary authority manages the money supply to achieve specific goals. Usually the goal of monetary policy is to accommodate economic growth in an environment of stable prices. For example, it is clearly stated in the Federal Reserve Act that the Board of Governors and the Federal Open Market Committee should seek “to promote effectively the goals of maximum employment, stable prices, and moderate long-term interest rates.”[10]
A failed monetary policy can have significant detrimental effects on an economy and the society that depends on it. These include hyperinflation, stagflation, recession, high unemployment, shortages of imported goods, inability to export goods, and even total monetary collapse and the adoption of a much less efficient barter economy. This happened in Russia, for instance, after the fall of the Soviet Union.
Governments and central banks have taken both regulatory and free market approaches to monetary policy. Some of the tools used to control the money supply include:
changing the rate at which the government loans or borrows money
currency purchases or sales
increasing or lowering government borrowing
increasing or lowering government spending
manipulation of exchange rates
raising or lowering bank reserve requirements
regulation or prohibition of private currencies
taxation or tax breaks on imports or exports of capital into a country
For many years much of monetary policy was influenced by an economic theory known as monetarism. Monetarism is an economic theory which argues that management of the money supply should be the primary means of regulating economic activity. The stability of the demand for money prior to the 1980s was a key finding of Milton Friedman and Anna Schwartz[11] supported by the work of David Laidler[12], and many others.
The nature of the demand for money changed during the 1980s owing to technical, institutional, and legal factors and the influence of monetarism has since decrease
