The Labor Market: The Medium RunThe Labor Market: The Medium Run

Higher production requires an increase in employment

Higher employment reduces unemployment

Lower unemployment puts pressure on wages

Higher wages increase production costs and therefore prices

A Medium Run Response to an Increase in DemandA Medium Run Response to an Increase in Demand



Higher prices lead workers to ask for higher wages….

Prices and wages (the labor market) adjust over the medium run and influence output

The Large Flow of WorkersThe Large Flow of Workers

Observations: 1. (Continued)

•Half of the flows from employment are quits•Half of the flows from employment are layoffs

1. The size of the flows into and out of employment




Observations:

•Average monthly flow out of unemployment is 2.4 million

•1.6 million to employment•0.8 million to out of the labor force

•Duration of unemployment is 3 months

2. The size of the flows into and out of unemploymentin relation to the total number of unemployed




Observations:

•Each month:•350,000 new people enter•200,000 retire

•The aggregate flow indicates that many people move back and forth from participants to non-participants

Movements in UnemploymentMovements in Unemployment

To Summarize:To Summarize:

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

Two Observations:Two Observations:

1. Workers’ wages exceed theirreservation wage

2. Wages depend on labor-marketconditions



Bargaining power depends on:Bargaining power depends on:

1. How easily can a worker be replaced.

2. How easily a worker can find anotherjob.




Efficiency Wages:Efficiency Wages:

Wages above the reservation wage thatincrease productivity and reduce theturnover rate.

Price Determination and the Production FunctionPrice Determination and the Production Function

Assume labor is the only input, thenAssume labor is the only input, then

Output (Y) = ANN = EmploymentA = Labor Productivity

Assume A=1Y = N

If Y=N: then marginal cost = Wage (W)



Price Determination and the Production FunctionPrice Determination and the Production Function

When perfect competition exists in the product marketWhen perfect competition exists in the product market

Price (P) = Marginal CostGiven: Marginal cost = WThen: P=W

In non-competitive markets P=(1+µ)W

A SummaryA Summary

Assume: The expected price = actual price level

Then: • Wage setting implies the real wage is inversely related to unemployment

•The price setting real wage is constant

•Labor market equilibrium occurs when W/P wage setting = W/P price setting

•Labor market equilibrium determines the unemployment rate – the natural rate of unemployment

• Wage setting implies the real wage is inversely related to unemployment

•The price setting real wage is constant

•Labor market equilibrium occurs when W/P wage setting = W/P price setting

•Labor market equilibrium determines the unemployment rate – the natural rate of unemployment



Where We Go From HereWhere We Go From Here

Recall: • Labor market equilibrium determines the natural level of unemployment which determines the natural level of output

• Labor market equilibrium determines the natural level of unemployment which determines the natural level of output

Observe: • Monetary policy, fiscal policy, consumer confidence does not impact the natural level of unemployment and output

• Monetary policy, fiscal policy, consumer confidence does not impact the natural level of unemployment and output



Where We Go From HereWhere We Go From Here

Short-Run • Price level may not equal the expected price

• Unemployment may equal natural unemployment level

• Output may equal natural output

• Price level may not equal the expected price

• Unemployment may equal natural unemployment level

• Output may 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
