Milton Friedman (1912–2006) was a prominent U.S. economist renowned for his robust endorsement of free-market capitalism and for pioneering the economic theory known as monetarism. His ideas and contributions have had a profound impact on both academic economics and practical economic policies throughout the late 20th century.
Early Life and Education
Milton Friedman was born on July 31, 1912, in Brooklyn, New York. He earned his undergraduate degree in economics from Rutgers University in 1932 and later his Ph.D. from Columbia University in 1946. His academic career included long-term associations with the University of Chicago, where he became one of the leading members of the Chicago School of Economics.
Key Contributions to Economics
Free-Market Capitalism
Friedman was a steadfast proponent of free-market capitalism, arguing that economic freedom is a prerequisite for political and social freedom. His belief was that minimal government intervention leads to more efficient allocation of resources, greater innovation, and overall higher standards of living.
Monetarism
Monetarism, one of Friedman’s most significant contributions, is an economic theory that emphasizes the role of governments in controlling the amount of money in circulation. Friedman argued that variations in the money supply have major influences on national output in the short run and the price level over longer periods. His famous quote, “Inflation is always and everywhere a monetary phenomenon,” encapsulates this principle.
In the equation \(MV = PQ\), \(M\) represents the money supply, \(V\) is the velocity of money, \(P\) stands for the price level, and \(Q\) denotes the output or real GDP. Friedman posited that managing the growth of money supply can stabilize economic growth and control inflation.
Major Works and Publications
Among his numerous influential works, the following stand out:
- “A Monetary History of the United States, 1867-1960” co-authored with Anna Schwartz, which delves into the role of money supply in American economic history.
- “Capitalism and Freedom”, where he argues for the necessity of economic freedom.
- “Free to Choose”, co-authored with his wife Rose Friedman, which further popularizes his ideas about free markets.
Historical Context and Impact
Friedman’s ideas gained prominence during a period characterized by government interventionist policies, notably Keynesian economics, which advocated for active government management of the economy. His theories provided a counter-narrative emphasizing minimal government intervention and deregulation.
In practical terms, his ideas were instrumental in shaping policies during the late 20th century, influencing the economic approaches of leaders such as US President Ronald Reagan and UK Prime Minister Margaret Thatcher.
Application of Friedman’s Theories
Economic Policy
Friedman’s monetarist ideas influenced the monetary policies adopted by central banks worldwide, particularly during the late 1970s and 1980s. His advocacy for monetary policy rules led to more predictable and stable economic environments.
Public Policy
His work also extended beyond pure economics into public policy, advocating for school vouchers, a volunteer military, and negative income tax to support low-income workers—all aimed at reducing government interference in personal and economic liberty.
Comparisons and Related Terms
Keynesian Economics
Keynesian economics, named after John Maynard Keynes, supports active government intervention to manage economic cycles. While Keynesians emphasize fiscal policy, Friedman’s monetarist approach underscores the significance of controlling the money supply.
Supply-Side Economics
Supply-side economics focuses on boosting economic growth by increasing the supply of goods and services, primarily through tax cuts and deregulation. While both support reduced government intervention, monetarism is centered around controlling the money supply.
