Historical Context
Monetarism gained prominence in the mid-20th century, primarily through the work of economist Milton Friedman. It emerged as a response to the perceived limitations of Keynesian economics, particularly its emphasis on government intervention in stabilizing economies. Monetarism stresses the importance of controlling the money supply to achieve economic stability.
Key Components of Monetarism
- Money Supply as a Key Economic Indicator: Monetarists argue that variations in the money supply are the primary driver of changes in nominal GDP and price levels.
- Market Clearing: Monetarism assumes that markets tend to naturally reach equilibrium, meaning supply equals demand.
- Rational Expectations: People form expectations about the future based on all available information, making it difficult for government intervention to systematically manage demand.
- Policy Implications: Governments should focus on maintaining a steady growth in the money supply rather than attempting to manage aggregate demand through fiscal policies.
Monetarist Policies
The central policy recommendation of monetarism is for the government to ensure a constant growth rate of the money supply. This growth rate should be in line with the economy’s long-term growth potential and any targeted rate of inflation, often argued to be zero.
Mathematical Models and Formulas
A fundamental equation in monetarism is the Quantity Theory of Money:
Where:
- \( M \) is the money supply.
- \( V \) is the velocity of money (the rate at which money circulates in the economy).
- \( P \) is the price level.
- \( Y \) is the real output or national income.

Importance and Applicability
Monetarism has significantly influenced modern economic policy, particularly in the late 20th century. Central banks often adopt monetarist principles, focusing on controlling inflation through monetary policy rather than fiscal interventions.
Examples
A practical example of monetarism in action is the use of interest rate adjustments by central banks to control the money supply. By increasing or decreasing interest rates, central banks can influence the amount of money circulating in the economy.
Considerations and Criticisms
- Limitations: Monetarism has faced criticism, particularly during economic crises when markets fail to clear efficiently, and the velocity of money can be unstable.
- Applicability: The theory assumes a relatively stable velocity of money and flexible prices, conditions that do not always hold in real-world scenarios.
Related Terms
- Keynesian Economics: An economic theory advocating for government intervention to manage aggregate demand.
- Inflation Targeting: A monetary policy strategy used by central banks to maintain price stability by targeting a specific inflation rate.
Comparisons
- Monetarism vs. Keynesian Economics: While monetarism emphasizes controlling the money supply, Keynesian economics focuses on fiscal policies to manage demand. Monetarism is less supportive of active government intervention compared to Keynesian economics.
Interesting Facts
- Influence on Central Banks: The monetarist emphasis on controlling inflation influenced the establishment of independent central banks.
- Global Adoption: Monetarist principles have been adopted by central banks worldwide, particularly during the late 20th and early 21st centuries.
Famous Quotes
- Milton Friedman: “Inflation is always and everywhere a monetary phenomenon.”
Proverbs and Clichés
- “Money makes the world go round”: This cliché underscores the centrality of money supply in economic activities.
Expressions and Jargon
- “Tightening the money supply”: Reducing the amount of money circulating in the economy to control inflation.
- “Velocity of money”: The rate at which money changes hands within the economy.

Summary
Monetarism is a fundamental economic theory emphasizing the crucial role of money supply in achieving economic stability and growth. Advocated by Milton Friedman, it recommends a steady and controlled increase in the money supply aligned with the natural growth of aggregate supply and inflation targets. Despite criticisms, monetarism has significantly shaped monetary policies worldwide, with its principles influencing the functioning of central banks.
