In this chapter you will learn to
1. Explain why wage differentials exist in both competitive
and noncompetitive labor markets.
2. Describe the effects of legislated minimum wages.
3. Explain why unions face a tradeoff between wages and
employment.
4. Describe facts and to recognize government policies related
to gender and race issues in the labor market.
5. Explain why the trend away from manufacturing jobs and
toward service jobs is not necessarily a problem for the
economy as a whole.

Wage Differentials
Wage Differentials in Competitive Markets
In competitive labour markets, supply and demand set the
equilibrium wage and level of employment.
But wages will still differ across workers if there are
compensating differentials.

Wage Differentials
Even if all jobs are the same (no compensating differentials),
there may still be some equilibrium wage differentials:
- different working conditions
- inherited skills are different across workers and can
be important
- investment in human capital is costly, and the return
is usually in terms of higher future wages

Wage Differentials and Human Capital
Changes in the pattern of human-capital acquisition lead to
changes in the supply of high-skilled versus low-skilled
labour.
These changes erode the wage differentials.
But as long as human capital is costly to acquire, some
wage differentials will persist in equilibrium.

Wage Differentials in Noncompetitive
Markets
A Union in a Competitive Labor Market
A labor union has monopoly power:
- it can change the supply of labor
 driving up the wage
Firms are generally able to choose the level of employment,
once the wage is determined in negotiations.

Bilateral Monopoly: Monopsony
with a Labor Union
S = AC
The union can raise
wages and
employment above
the monopsony levels.

If the union pushes
wages up only to the
competitive level,
employment would also
rise to the competitive
level.

Legislated Minimum Wages
Government policy can affect labor markets by legislating
minimum wages.
In a competitive market, a binding minimum wage reduces
employment and creates unemployment.
But in the presence of monopsony power, a binding minimum
wage may simultaneously increase wages and employment.

A Final Word
We have learned several explanations for why some
workers get paid more than others, including:
1. workers’ education and skills
2. job characteristics
3. structure of labor markets

Labor Unions
Labor unions are not as important in the U.S. today than
they have been in the past. Only 7.8% of all private-sector
workers were members of a union in 2005, as compared
to almost 25% in the early 1970s.

Collective Bargaining
In collective bargaining, the firm and the union typically
bargain over wages and other working conditions.
The firm usually retains the right to choose the level of
employment.
The more successful a union is at raising wages, the fewer
union members will be employed.

Union Wage Premium
Unionized workers earn, on average, between 10 and 20
percent higher wages than non-unionized workers with similar
characteristics.
But there is little empirical evidence that firms hire fewer
workers as a result of the higher wages.
Some economists explain this apparent contradiction with the
concept of featherbedding.

Unanswered Questions
Unions may reduce long-run productivity through a process
known as the hold-up of capital.
Much physical capital, once installed, has a very inelastic
supply, and the union may hold up the firm by forcing it to
pay higher wages.
If firms are forward-looking, they will anticipate this behavior,
and might reduce investment.
Lower investment may reduce productivity growth in the
industry.

Gender and Race in the Labor Market
In 2005, black workers on average earned 70% and Hispanic
workers earned 63% of non-Hispanic whites. Female workers
earned about 69% of what male workers earned.
Possible explanations for the observed disparity:
- differences in education and human capital
- occupational segregation
Policies to eliminate discrimination:
- equal opportunity and access in the workplace
- affirmative action

Policies to Eliminate Discrimination
Prior to the civil rights movement of the 1960s, discrimination
was tolerated and in some cases even promoted.
In the 1960s, two types of policies were introduced to counter
the effects of discrimination:
1. Equal opportunity and access (Equal Pay Act of
1963 and Title VII of the Civil Rights Act
2. Affirmative action policies

The “Good Jobs–Bad Jobs” Debate
In 1945, the goods-producing sector accounted for 40% of
U.S. employment, and services accounted for less than
50%. Today the numbers are 17% for goods and over 70%
for services.
One concern is that many of the “good jobs” in the
manufacturing sector appear to have been replaced by
“bad jobs” in the service sector.
Is the shift toward services a problem?

Five Observations
1. Real income per hour worked has been rising throughout
the past century. As a nation, we are getting wealthier.
2. Low-paying service-sector jobs play an important role in
the U.S. economy, especially for young workers.
3. The fall in manufacturing’s employment share is partly due
to that sector’s dynamism.

Five Observations
4. As income grows, demand naturally switches to many
services.
5. Increases in the quality of services lead to rising living
standards.

A Mixed Blessing?
The transition of workers from agriculture to manufacturing to
services can be difficult for the individuals involved.
This suggests a role for government to maintain the income of
those who are temporarily unemployed.
The goal is to ease such transitions, not block them.
