Understanding Okun's Law
Okun's law describes the empirical relationship between unemployment and economic growth. It states that for every 1% increase in the unemployment rate above the natural rate, GDP growth decreases by approximately 2%.
Okun's Law Formula
Basic Okun's Law
- ?Y/Y = ß × (U - U*)
- ?Y/Y = GDP growth rate
- U = Actual unemployment rate
- U* = Natural unemployment rate
- ß = Okun's coefficient (typically 2.0)
Alternative Formulation
- ?U = -ß × (?Y/Y)
- ?U = Change in unemployment
- ?Y/Y = GDP growth rate
- ß = Okun's coefficient
- Shows unemployment-GDP relationship
Components of Okun's Law
Key Elements of the Relationship
GDP Gap
- Difference between actual and potential GDP
- Negative gap indicates recession
- Positive gap indicates overheating
- Measured as percentage of potential GDP
Cyclical Unemployment
- Unemployment above natural rate
- Caused by business cycle fluctuations
- Zero at full employment
- Key indicator of economic slack
Okun's Coefficient Variations
| Country/Economy | Okun's Coefficient | Time Period | Notes |
|---|---|---|---|
| United States | 2.0 - 2.5 | Post-WWII | Original Okun's estimate |
| Euro Area | 1.5 - 2.0 | 1999-2019 | Lower due to labor market rigidities |
| United Kingdom | 1.8 - 2.2 | 1970-2019 | Stable relationship |
| Japan | 1.0 - 1.5 | 1980-2019 | Lower due to demographic factors |
