Main Idea
The unemployment rate measures the share of the labor force that is jobless and actively seeking work. Labor markets, like other markets, are shaped by supply (workers) and demand (employers).
Key Concepts
- Labor force = employed + unemployed people actively seeking work (excludes discouraged workers not looking)
- Unemployment rate = (number unemployed / labor force) x 100
- Frictional unemployment: short-term, from people between jobs or entering the workforce
- Structural unemployment: mismatch between workers' skills and available jobs
- Cyclical unemployment: caused by downturns in the business cycle (recessions)
- Natural rate of unemployment: the 'normal' level combining frictional and structural unemployment when the economy is at full employment
- Minimum wage: a price floor on labor that, if set above equilibrium wage, can reduce quantity of labor demanded
Diagram (described)
A labor market graph has 'Wage' on the y-axis and 'Quantity of workers' on the x-axis; supply of labor slopes up, demand for labor slopes down. A minimum wage set above equilibrium creates a labor surplus (more people want jobs than employers want to hire).
Common Mistakes
- Assuming the unemployment rate counts everyone without a job (it excludes those not actively looking)
- Confusing frictional (normal, short-term) with cyclical (recession-driven) unemployment
- Assuming minimum wage increases always cause large job losses — effects depend on how far above equilibrium the wage is set
Key concepts
Important terms
- Unemployment rate
- The percentage of the labor force that is jobless and actively seeking work.
- Frictional unemployment
- Short-term unemployment from workers transitioning between jobs or entering the labor force.
- Structural unemployment
- Unemployment caused by a mismatch between workers' skills and the skills employers need.
- Cyclical unemployment
- Unemployment that rises and falls with the business cycle, especially during recessions.
Worked examples
Problem
A country has a labor force of 10 million, of which 600,000 are unemployed. What is the unemployment rate?
- 1. Unemployment rate = (unemployed / labor force) x 100
- 2. = (600,000/10,000,000) x 100
Answer: 6% unemployment rate
Quick revision
- Unemployment rate = unemployed / labor force x 100
- Labor force excludes people not actively seeking work
- Frictional unemployment is short-term and normal
- Structural unemployment reflects skill mismatches
- Cyclical unemployment rises during recessions
- Minimum wage above equilibrium can create a labor surplus
