The Labor Market: Wages … Prices … Wages
• Higher production requires an increase in employment
• Higher employment reduces unemployment
• Lower unemployment puts pressure on wages
• Higher wages increase production costs and prices
• Higher prices lead workers to ask for higher wages….
• Prices and wages (the labor market) adjust over the medium run and influence output

Movements in UnemploymentMovements in Unemployment
High Unemployment:
•Increases the probability of workers losing their jobs•Reduces the probability of the unemployed finding a job•Increases the duration of unemployment

Wage DeterminationWage Determination
1.Workers’ wages exceed their reservation wage
2. Wages depend on labor-market conditions:
•How easily can a worker be replaced?•How easily a worker can find another job?
•Efficiency Wages: Wages above the reservation wage• Increase productivity
•Morale up•Shirking down•Monitoring costs down
•Reduce turnover rate.•Reduce hiring costs.

•Workers base their wage request on the purchasing power of their wages or real wage they expect, W/Pe

Output Y = ANN = EmploymentA = Labor Productivity
Assume A=1Y = N
If Y = N: then marginal cost = Wage (W)

Short-Run • Price level may not equal the expected price
• Unemployment may not equal natural unemployment level
• Output may not equal natural output
• Price level may not equal the expected price
• Unemployment may not equal natural unemployment level
• Output may not equal natural output
Medium-Term
• Price level tends to equal expected prices
•Unemployment tends to the natural rate
•Output moves toward the natural rate
• Price level tends to equal expected prices
•Unemployment tends to the natural rate
•Output moves toward the natural rate
