What Is Milton Friedman?

Milton Friedman was a highly influential American economist and statistician who was awarded the 1976 Nobel Memorial Prize in Economic Sciences for his significant contributions to consumption analysis, monetary history and theory, and the complexities of stabilization policy³⁹. He is widely recognized as a leading figure of the Chicago School of Economics and the principal advocate of monetarism, a school of thought within monetary economics that emphasizes the role of the money supply in determining economic activity and inflation³⁸. Milton Friedman's work challenged prevailing economic orthodoxies and profoundly shaped modern views on monetary policy and the role of government intervention in markets³⁷.

History and Origin

Born in Brooklyn, New York, in 1912, Milton Friedman's academic journey led him to the University of Chicago, where he would become a prominent professor and intellectual leader. His intellectual development was shaped by the "old" Chicago School, which emphasized free markets and the quantity theory of money³⁶.

Friedman's collaboration with Anna Schwartz, an economic historian, culminated in the seminal 1963 publication A Monetary History of the United States, 1867–1960. This monumental work meticulously documented the relationship between monetary aggregates and macroeconomic variables over nearly a century, presenting a compelling argument that fluctuations in the money supply were the primary drivers of business cycles. ³⁵A significant portion of this work focused on the Great Depression, arguing that the Federal Reserve's failure to prevent a sharp contraction in the money supply significantly worsened the economic downturn. ³³, ³⁴This historical analysis provided a strong empirical foundation for monetarism and directly challenged the then-dominant Keynesian economics view that emphasized fiscal policy.

Key Takeaways

• Milton Friedman was a Nobel laureate economist known for his advocacy of monetarism and free-market principles.
• He argued that inflation is primarily a monetary phenomenon, caused by excessive growth in the money supply.
• Friedman's work with Anna Schwartz, A Monetary History of the United States, 1867–1960, posited that Federal Reserve actions exacerbated the Great Depression.
• He championed limited government intervention, advocating for laissez-faire policies and rules-based monetary policy.
• His theories had a profound impact on economic thought and policy, particularly during the 1970s and 1980s.

Interpreting the Milton Friedman

Milton Friedman's economic philosophy is largely characterized by a belief in the efficiency of free markets and a skepticism towards extensive government intervention. A core tenet of his thought, central to monetarism, is the idea that "inflation is always and everywhere a monetary phenomenon," meaning that sustained increases in general price levels are a direct result of the money supply growing faster than the output of goods and services.

H³⁰, ³¹e argued that central banks, like the Federal Reserve, should prioritize maintaining a stable growth rate of the money supply to control inflation and promote long-term economic stability, rather than attempting to fine-tune the economy through discretionary monetary policy. Fr²⁹iedman also posited that there is no long-run trade-off between inflation and unemployment, a concept known as the natural rate of unemployment hypothesis, which challenged the stability of the Phillips Curve. Hi²⁷, ²⁸s views significantly influenced the concept of rational expectations within macroeconomic theory.

Illustrative Policy Impact

Milton Friedman's theories had a tangible impact on economic policy, particularly evident in the shift in how central banks approached monetary management. Prior to Friedman, many policymakers, influenced by Keynesian thought, focused on interest rates as the primary tool for economic stabilization. Friedman, however, argued that controlling the money supply was paramount.

A²⁶ significant illustration of his influence can be seen in the response to the high inflation and stagflation of the 1970s. As traditional Keynesian demand-management policies struggled to address simultaneous high inflation and unemployment, Friedman's monetarist ideas gained traction. Ce²⁵ntral banks, including the U.S. Federal Reserve under Paul Volcker, adopted policies focused on controlling the money supply to combat inflation, leading to a period of disinflation in the early 1980s. Wh²⁴ile the exact mechanisms and full extent of his direct influence are debated, this period marked a notable shift towards monetarist principles in practice, emphasizing price stability as a key objective of monetary policy.

#²³# Practical Applications

Milton Friedman's ideas found practical application in several areas of finance and public policy:

• Central Bank Operations: His emphasis on the money supply's role in inflation influenced central banks worldwide to focus more on inflation targeting and stable monetary growth rules, moving away from purely discretionary interventions.
• ²² Anti-Inflation Strategies: Friedman's assertion that inflation is a monetary phenomenon provided a theoretical basis for policies aimed at curbing rapid money supply growth to control rising prices. Th²⁰, ²¹is was particularly relevant during periods of high inflation.
• Deregulation Advocacy: Consistent with his belief in free markets and limited government, Friedman advocated for deregulation across various industries, arguing that such measures would foster greater economic efficiency and innovation.
• ¹⁹ Privatization Debates: His philosophical stance supported the privatization of public services and state-owned enterprises, believing that private sector efficiency often surpasses that of government-run operations.
• Monetary Policy during Crises: Friedman and Anna Schwartz's analysis of the Great Depression, detailed in A Monetary History of the United States, 1867–1960, profoundly influenced future central bank responses to financial crises. Form¹⁷, ¹⁸er Federal Reserve Chair Ben Bernanke, for instance, acknowledged the Fed's role in exacerbating the Great Depression and applied lessons from Friedman's work to the 2008 financial crisis, emphasizing the importance of providing ample liquidity to the banking system.

¹⁵, ¹⁶Limitations and Criticisms

Despite his profound influence, Milton Friedman's theories and policy recommendations faced several limitations and criticisms. One significant critique concerned the practical difficulties of precisely defining and controlling the money supply, particularly as financial innovations led to new forms of money and credit. Crit¹⁴ics argued that the relationship between the money supply and economic activity was not as stable or predictable as monetarism suggested.

Another area of contention was his stance on corporate social responsibility. Friedman famously argued in 1970 that "the social responsibility of business is to increase its profits," a view that has drawn considerable criticism for potentially neglecting broader societal impacts such as environmental concerns, labor welfare, and ethical considerations. This¹², ¹³ perspective is often seen as being at odds with modern concepts like stakeholder capitalism.

Furthermore, while his natural rate of unemployment hypothesis and critique of the stable Phillips Curve gained widespread acceptance, some economists debated the speed at which expectations adjust and the implications for short-run policy effectiveness. His ¹¹critics also contended that over-reliance on a strict money supply rule could lead to excessive economic volatility if other factors affecting demand and output were ignored. The ¹⁰economic consequences of monetarist policies in some countries, such as the UK in the early 1980s, were also cited as evidence of potential drawbacks, including increased unemployment and a decline in manufacturing.

⁹Milton Friedman vs. Keynesian Economics

Milton Friedman and the broader Chicago School stood in stark contrast to Keynesian economics, the dominant economic paradigm for much of the mid-20th century. The fundamental difference lies in their views on government intervention and the primary drivers of economic stability.

While Keynesians focused on managing aggregate demand through fiscal policy to combat unemployment, Milton Friedman argued that excessive government spending and discretionary monetary policy could lead to inflation and distort market signals. His work was instrumental in shifting macroeconomic thought away from pure Keynesianism, particularly in response to the stagflation of the 1970s, which Keynesian models struggled to explain.

H⁵ow did Milton Friedman's views differ from Keynesian economists?

Milton Friedman's views differed significantly from Keynesian economists primarily in their approach to economic stabilization and the role of government. Friedman championed the importance of monetary policy and a stable money supply to control inflation, while Keynesian economics emphasized discretionary fiscal policy (government spending and taxation) to manage demand and reduce unemployment.

W³, ⁴hat is the "natural rate of unemployment" concept proposed by Friedman?

The "natural rate of unemployment" is a concept advanced by Milton Friedman, suggesting that there is a level of unemployment below which efforts to stimulate the economy (e.g., through increased money supply) will only lead to accelerating inflation without a lasting reduction in unemployment. This c¹, ²hallenged the traditional Phillips Curve idea of a stable long-run trade-off between inflation and unemployment.
