Unemployment
- How long are people unemployed?
- Numerical example:
- Labor force = 100; on the first day of every month, two workers become unemployed for one month each; on the first day of every year, four workers become unemployed for one year each
- Result: 28 spells of unemployment during a year; 24 short (one month), four long (one year); so most spells are short
- At any date, unemployment = six; four have long spells (one year), two have short spells (one month); so most unemployed people on a given date have long spells

Structural Unemployment

- One cause: Lack of skills prevents some workers from finding long-term employment
- Another cause: Reallocation of workers out of shrinking industries or depressed regions; matching takes a long time

Relating Output and Unemployment: Okun’s Law
- Why is the Okun’s Law coefficient 2, and not 1?
- Other things happen when cyclical unemployment rises: Labor force falls, hours of work per worker decline, average productivity of labor declines
- Result is 2% reduction in output associated with 1 percentage point increase in unemployment rate
