Job Loss, Job Finding, and the Natural Rate of Unemployment

Labor Force = # Employed + # UnemployedL = E + U

Unemployment Rate = U/L

Rate of Job Finding = Rate of Job Separation fU = sE

Substitute for E:fU = s(L - U)

Divide by L:f(U/L) = s{1 - (U/L)}

Solve for U/L:(U/L) = s/(f + s)

Suppose 1 percent of employed lose their jobeach month (average job lasts 100 months), s = 0.01And 20 percent of unemployed find a job each month(average spell of unemployment is 5 months), f = 0.2Then, U/L = 0.01/(0.01 + 0.2) = 0.0476

Job Search and Frictional Unemployment

Takes time to search for a job as a person must learn about opportunities, may have to move to a new location, may not want to take the first job that is offered

Shifts in the composition of demand occur among industries or regions may occur and lead to shifts in demand for certain skills

Natural consequence of continually changing demand and supply for labor

Public Policy and Frictional Unemployment

Unemployment Insurance may lead to a higher natural rateof unemployment

Experience Rating may lower the distortionary effect of suchinsurance

Illinois’ experiment with “bonus” for finding work sooner

Real-Wage Rigidity and Structural Unemployment

Labor market doesn’t clear

Real wage is “stuck” above its equilibrium level

Supply of labor exceeds demand for labor

Workers are waiting for jobs to become available

Reasons for Wage Rigidity

1. Minimum-Wage Laws

2. Unions and Collective Bargaining--role of “Insiders and “Outsiders”

3. Efficiency Wages: High Wages make workers more productive

How Do Wages Affect Productivity?

A. Nutrition Effect

B. Reduction in Labor Force Turnover

C. Higher Quality of Work Force--Adverse Selection

D. Improves Worker Effort--Monitoring Problem Moral Hazard

Patterns of Unemployment

Average Spell of Unemployment is Short

Most Time Unemployed is Borne by Relatively Few Workers

Variation is Great Across Demographic Groups
