The natural rate of unemployment is a key concept in Keynesian economics, representing the unemployment rate that would prevail in an economy with a constant rate of inflation. It is influenced by various institutional factors and is considered ’natural’ not because it is desirable or inevitable, but because it cannot be permanently reduced through demand management without causing inflation to rise.
Historical Context
The term and concept were developed to address the limitations of earlier economic theories, particularly those that suggested a direct and constant trade-off between inflation and unemployment, as illustrated by the Phillips curve. In the 1970s, economists Milton Friedman and Edmund Phelps introduced the idea of the natural rate of unemployment to explain that this trade-off could not be exploited in the long term without leading to accelerating inflation.
Types/Categories
- Frictional Unemployment: Unemployment that occurs when people are between jobs or entering the labor force for the first time.
- Structural Unemployment: Unemployment arising from a mismatch between the skills that workers have and the skills needed by employers.
- Classical Unemployment: Unemployment resulting from wages being higher than the equilibrium level, often due to minimum wage laws or union activity.
Key Events
- 1968: Milton Friedman introduces the concept of the natural rate of unemployment in his Presidential Address to the American Economic Association.
- 1970s: Stagflation (high inflation and high unemployment) challenges the existing economic paradigms and underscores the relevance of the natural rate of unemployment.
Detailed Explanations
The natural rate of unemployment is a dynamic concept influenced by factors such as:
- Industrial Monopolies: Dominant firms may create barriers to entry, affecting employment levels.
- Social Security Systems: Generous benefits may reduce the incentive to seek employment.
- Minimum Wage Legislation: Higher minimum wages can increase unemployment if they exceed the equilibrium wage.
- Mobility Restrictions: Geographic or occupational immobility can prevent workers from finding suitable jobs.
- Trade-Union Organization: Strong unions may negotiate higher wages, which can lead to unemployment if the wages are above the market-clearing level.
Mathematical Formulas/Models
Economists often use the Non-Accelerating Inflation Rate of Unemployment (NAIRU) to operationalize the natural rate of unemployment. It is calculated using various econometric models that take into account inflation expectations and actual inflation rates.

Importance and Applicability
The natural rate of unemployment is crucial for policymakers:
- Monetary Policy: Central banks use it to set interest rates to control inflation.
- Fiscal Policy: Governments use it to design unemployment benefits and job creation programs.
- Labor Market Policies: Understanding the natural rate helps in designing policies to reduce structural unemployment.
Examples
- United States: In the 1990s, the natural rate of unemployment was estimated to be around 5-6%, but policies aimed at increasing labor market flexibility have helped to lower it.
- European Union: Countries with stronger labor protections often have higher natural rates of unemployment due to less labor market flexibility.
Considerations
- Policy Influence: Policymakers can influence the natural rate through education, training programs, and reforms to labor market regulations.
- Economic Shocks: Temporary shocks (like technological changes or financial crises) can affect the natural rate.
- Globalization: Increased global competition can influence structural unemployment by changing the types of jobs available.
Related Terms with Definitions
- Phillips Curve: A graphical representation showing the inverse relationship between inflation and unemployment.
- NAIRU: Non-Accelerating Inflation Rate of Unemployment, a concept closely related to the natural rate.
Comparisons
- NAIRU vs. Natural Rate: NAIRU focuses specifically on the rate of unemployment at which inflation does not accelerate, while the natural rate includes broader institutional factors.
Interesting Facts
- Changing Estimates: The estimated natural rate of unemployment changes over time due to shifts in economic conditions and policy environments.
Inspirational Stories
- Nordic Model: Scandinavian countries have successfully maintained low natural rates of unemployment through a combination of flexible labor markets and strong social safety nets.

Final Summary
The natural rate of unemployment is an essential concept in Keynesian economics, reflecting the complexities of labor markets and the interplay between employment and inflation. Understanding this rate helps in crafting effective monetary, fiscal, and labor market policies. It is influenced by a variety of institutional factors and can change over time due to policy interventions and economic shifts. By considering both the theoretical underpinnings and real-world applications, policymakers and economists can better address the challenges of unemployment while managing inflationary pressures.
