Study Notes
Unemployment Rate
- Unemployment rate indicates the percentage of the labor force that is currently jobless.
- It is calculated by dividing the number of unemployed individuals by the total labor force, represented as a percentage.
Example Calculation of Unemployment Rate
- Total civilian population over 16: 300 million.
- Employed: 225 million, Unemployed: 25 million, Not in labor force: 50 million.
- Labor force = Employed + Unemployed = 225 million + 25 million = 250 million.
- Unemployment Rate = (25 million / 250 million) × 100 = 10%.
Bathtub Model of Unemployment
- A permanent increase in the job finding rate reduces the natural rate of unemployment.
- The model represents a steady-state equilibrium, focusing on the long-run natural unemployment rate.
Natural Rate of Unemployment Calculation
- If 21% of unemployed find jobs and 0.9% of employed lose jobs, the natural rate of unemployment stabilizes at 3.5%.
Labor Demand Curve
- Downward sloping due to diminishing marginal product of labor as more workers are added.
- Represents a firm's optimization as adding more labor leads to decreasing returns.
Income Inequality Trends
- Post-1980, rising income inequality in the U.S. is linked to salaries and business incomes rather than capital income, based on analyses by Thomas Piketty and Emmanuel Saez.
Employment-Population Ratio
- Increasing employment-population ratio in the U.S. is primarily driven by higher female labor force participation.
Unemployment in Europe vs. U.S.
- Europe's higher unemployment rates in the past two decades stem from inefficient unemployment insurance and productivity downturns/high oil prices in the 1970s.
Cyclical Unemployment
- Defined as unemployment that fluctuates in response to economic cycles, such as a recession.
- An example includes a worker being laid off due to economic downturns.
Types of Unemployment
- Cyclical unemployment is linked to business cycle fluctuations.
- Natural unemployment consists of frictional and structural unemployment.
- Frictional unemployment occurs when individuals take their time to find suitable jobs.
- Structural unemployment arises when there is a mismatch between workers’ skills and available job requirements.
