Price controls

Price controls are governmental restrictions on the prices that can be charged for goods and services in a market. The intent behind implementing such controls can stem from the desire to maintain affordability of staple foods and goods, to prevent price gouging during shortages, and to slow inflation, or, alternatively, to insure a minimum income for providers of certain goods or a minimum wage. There are two primary forms of price control, a price ceiling, the maximum price that can be charged, and a price floor, the minimum price that can be charged.

Historically, price controls have often been imposed as part of a larger incomes policy package also employing wage controls and other regulatory elements.

Although price controls are sometimes used by governments, economists usually agree that price controls don't accomplish what they are intended to do and are generally to be avoided. For example, nearly three-quarters of economists would disagree with the statement, "Wage-price controls are a useful policy option in the control of inflation."

Milton Friedman

Milton Friedman (July 31, 1912 – November 16, 2006) was an American economist who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory and the complexity of stabilization policy. With George Stigler and others, Friedman was among the intellectual leaders of the second generation of Chicago price theory, a methodological movement at the University of Chicago's Department of Economics, Law School, and Graduate School of Business from the 1940s onward. Several students and young professors that were recruited or mentored by Friedman at Chicago went on to become leading economists; they include Gary Becker, Robert Fogel, and Robert Lucas, Jr..

Friedman's challenges to what he later called "naive Keynesian" theory began with his 1950s reinterpretation of the consumption function. In the 1960s, he became the main advocate opposing Keynesian government policies, and described his approach (along with mainstream economics) as using "Keynesian language and apparatus" yet rejecting its "initial" conclusions. He theorized that there existed a "natural" rate of unemployment, and argued that employment above this rate would cause inflation to accelerate. He argued that the Phillips curve was, in the long run, vertical at the "natural rate" and predicted what would come to be known as stagflation. Friedman promoted an alternative macroeconomic viewpoint known as "monetarism", and argued that a steady, small expansion of the money supply was the preferred policy. His ideas concerning monetary policy, taxation, privatization and deregulation influenced government policies, especially during the 1980s. His monetary theory influenced the Federal Reserve's response to the global financial crisis of 2007–08.
