Earnings, Productivity,
and the Job Market
Why Do Earnings Differ?
1. Non-identical Workers
2. Non-identical Jobs
3. Immobility of Labor
Earnings Differentials:
1. Non-identical Workers
• Worker productivity:
• More productive more money
• Tournament pay
• Worker preferences:
• If money is most important, pursue jobs
with higher wages.
• Race and gender:
• Discrimination.
Earnings Differences:
Skilled and Unskilled Workers
• The wages of unskilled workers are low relative to skilled
workers due to the less demand and large supply of
skilled workers relative to unskilled workers.
Wages
• Skilled workers
face strong demand
and small supply
relative to unskilled
workers.

Earnings Differentials:
2. Non-Identical Jobs
• Undesirable working conditions = higher wages
(compensating wage differentials).
• Compensating wage differentials factors:
•
•
•
•
Job risk
Job location
Working hours
Work environment
Earnings Differentials:
3. Immobility of Labor
• An incomplete adjustment to a change in
labor demand because of labor immobility.
• Immobility can result from:
• Specialized labor – derived demand, so lags
• Institutional barriers
• Minimum wage – fewer workers hired
• Occupational licensing - restricted
• Labor unions - restricted
Discrimination
1. Wage Discrimination
Lower wages for minorities
2. Employment Discrimination
Fewer jobs available for minorities
Wage Discrimination
• When majority workers are preferred to
minority workers (or men to women), demand
for minority workers is reduced.
• Minority workers receive lower wages.
Impact of Wage Discrimination
Wages
Employment discrimination
causes the demand for
minority services to
decrease.
• The result is lower
demand, and the
equilibrium wage will be at
a lower level, Ww > Wm .

Employment
Employment Discrimination
• Discriminated workers are restricted in the
types of jobs and occupations they enter.
• Supply in the unrestricted jobs will increase,
causing wages to fall in these jobs.
• When the supply (of minorities) to an occupation
is restricted, the wages (of white males) will rise.

Employment Discrimination
Discrimination is costly to employers.
• When employers can hire equally productive
minorities (or women) at a lower wage than whites
(men), the profit motive gives them a strong
incentive to do so.
• Employers who ignore minority and gender
status when employing workers will have lower
wage costs than employers who discriminate.
Employment Discrimination
and Earnings of Minorities
• Earnings may differ among groups for
reasons besides employment discrimination.
• To measure the extent of employment
discrimination, we must:
• Adjust earnings for differences between
groups in productivity-related factors such
as education
• Then make comparisons between similarly
qualified groups of workers who differ only
in race or gender.

Productivity and Earnings
Link Between Output and Earnings
• Productivity is the source of high wages.
• Workers in the U.S. earn high wages because
their output per hour is high as a result of:
• Greater worker knowledge and skills (human
capital)
• The use of modern machinery
(physical capital)
Productivity and Earnings
•Annual rate of increase of productivity and real
wages
•3.2 %
•2.9 %
•2.8 %
•2.0 %
•1.5 %
•0.7 %
•1948–1973
•Rise in output per hour
•(private business sector)
•1974–1995
•1996–2006
•Rise in real compensation
•(private business sector)
• Productivity & compensation per hour are closely related.
• Relative to the 1948-1973 period, growth in productivity
and real wages slowed between 1973 and 1995. Both
rebounded substantially during the 1996-2006 time frame.
Productivity and the New Economy
• Productivity rebounded significantly between
1996 and 2003 after being low for the prior
20 years.
• New Era view
• Proponents argue the increase in productivity
growth is the result of increased amounts of
information technology capital as well as a
speedup in technological change.
• Temporary Factors
• Critics argue cyclical factors were responsible
for the productivity growth.
Automation
• Automated methods of production will only
be adopted if they reduce costs.
• Automation may reduce employment in a
specific industry.
• It also releases resources that can be
employed in other areas.
• Improved technology permits us to achieve
larger output and income levels.
