Monetarism is a macroeconomic theory asserting that variations in the money supply are the primary determinant of national economic activity and inflation. Developed by Milton Friedman in the mid-20th century, this theory posits that controlling the growth rate of the money supply will lead to significant economic stability and growth.
The Core Theory of Monetarism
Monetarism argues that managing the money supply—an aggregate measure of all the money in an economy—is crucial to regulating economic cycles. Central to this theory is the Quantity Theory of Money, represented by the equation:
Where:
- \( M \) is the money supply
- \( V \) is the velocity of money (the rate of turnover of the money supply)
- \( P \) is the price level
- \( Q \) is the real output or quantity of goods and services produced.
Components Explained
- Money Supply (M): The total amount of money—cash, coins, and balances in bank accounts—available in an economy.
- Velocity of Money (V): The frequency at which one unit of currency is used to purchase domestically-produced goods and services within a given time period.
- Price Level (P): The average of the prices of goods and services in an economy, typically measured by a price index such as the Consumer Price Index (CPI).
- Real Output (Q): Also known as real GDP, this is the quantity of goods and services produced, adjusted for inflation.
Historical Context
Monetarism gained prominence during the 1970s and 1980s, a period characterized by high inflation and economic instability in many developed countries. Milton Friedman and Anna Schwartz notably championed the theory in their 1963 work “A Monetary History of the United States, 1867–1960,” which analyzed the relationship between monetary policy and economic performance.
Comparison to Keynesian Economics
Core Beliefs
-
Monetarism:
- Focuses on long-term monetary stability.
- Advocates for control of the money supply to influence economic output and inflation.
- Believes market forces are efficient and government intervention should be minimal.
-
Keynesian Economics:
- Concentrates on short-term economic fluctuations.
- Supports active government intervention, especially fiscal policy (government spending and taxation).
- Emphasizes the role of aggregate demand in driving economic growth and employment.
Policy Approaches
-
Monetarist Policies:
- Implementation of rules-based monetary policy.
- Emphasis on using interest rates to control inflation.
- Skepticism towards fiscal stimulus.
-
Keynesian Policies:
- Flexible fiscal and monetary policies based on current economic conditions.
- Use of government spending to boost demand during recessions.
- Advocacy for discretionary fiscal interventions.
Examples and Applications
A practical example of Monetarism in action is the Volcker Shock of the late 1970s and early 1980s when the U.S. Federal Reserve, under Chairman Paul Volcker, drastically reduced the money supply growth rate to combat double-digit inflation. The resulting economic policies brought significant short-term unemployment but ultimately reduced inflation and stabilized the economy.
Related Terms
- Inflation: A general increase in prices and fall in the purchasing power of money.
- Deflation: A decrease in the general price level of goods and services.
- Fiscal Policy: Government adjustments to spending levels and tax rates to influence an economy.
- Supply-Side Economics: A theory arguing that economic growth can be most effectively fostered by lowering taxes and decreasing regulation.

Summary
Monetarism provides a profound understanding of how the money supply influences economic stability. By focusing on the control and regulation of monetary aggregates, it offers an alternative to Keynesian economics’ reliance on fiscal policy, emphasizing long-term stability over short-term intervention. This theory’s relevance persists as policymakers navigate the challenges of modern economic management.
