3. Ratio of Female to Male Hourly Earnings
6/15/2018
Ratio of Female to Male Hourly Earnings
The ratio of female to male hourly earnings rose substantially from the late 1970s to the early 1990s and has leveled off since then.
The wage gap has decreased because the skills of women have risen, the industrial and occupational distributions have shifted in favor of women, the decline in unionism has decreased male wages more than female wages, and discrimination has declined.

Non-Discrimination Factors
Raw racial and gender differentials on earnings, occupational distribution, and unemployment data must be interpreted with caution.
Factors other than discrimination such as individual choice may play a role.

2. Discrimination and Its Dimensions
14-11

12. 6/15/2018
Discrimination
Discrimination exists when female or minority workers—who have the same abilities, education, training, and experience as white male workers—are accorded inferior treatment with respect to hiring, occupational access, promotion, wage rate, or working conditions.
14-12

13. Types of Discrimination
6/15/2018
Types of Discrimination
Wage discrimination
Female or black workers are paid less than male (white) workers for doing the same work.
Employment discrimination
Blacks and women bear a disproportionate share of unemployment.
Occupational job discrimination
Blacks and women are arbitrarily restricted from entering some occupations, even though they are as capable as male (white) workers.
14-13

14. Types of Discrimination
6/15/2018
Human capital discrimination
Blacks and women have less access to productivity-increasing opportunities such as formal schooling or on-the-job training.
Post-market discrimination
Occurs after a person has entered the labor market
Wage discrimination
Employment discrimination
Occupational job discrimination
Pre-market discrimination
Occurs before a person has entered the labor market

14-15

16. Taste for Discrimination
6/15/2018
Taste for Discrimination
Becker’s taste for discrimination assumes that discrimination is a “taste” for which a discriminator is willing to pay.
Society’s taste for discrimination implies that it is willing to forego output and profits as the price of discrimination.
Tastes for discrimination arise from sources:
Employers
Consumers
Employees
14-16

17. Discrimination Coefficient
6/15/2018
Discrimination Coefficient
If black and white workers are equally productive, a non-discriminatory employer will randomly hire black and white workers if the wages are the same.
The strength of a employer’s prejudice against black workers is measured by the discrimination coefficient--d.
For prejudiced employers, the cost of hiring a black worker is the worker’s wage (Wb) plus the psychic cost of hiring a black worker (d).

20. Outcomes of the model

21. Discrimination Coefficient
6/15/2018
Discrimination Coefficient
Prejudiced employers will be indifferent between white and black workers when:
Ww = Wb + d
A given employer will hire black workers, if the market white-black wage gap is greater than d.
14-21

22. Wage Discrimination in the Labor Market

Wage Discrimination in the Labor Market
Quantity of Black Workers
Wb/ Ww
The demand for black workers is formed by arraying employers from lowest for highest discrimination coefficients. Sb
The horizontal portion of the demand curve is composed of non-discriminating employers.
1.00 Db
0.8 Q
The downward sloping portion consists of discriminating employers.
The quantity supply of black workers supplied rises as the black-white wage ratio rises.
The intersection of the supply and demand for black workers determines the black-white ratio and the number of black workers employed.
14-22

23. Generalizations
6/15/2018
A change in the shape or location of the demand curve will alter the black-white wage ratio.
A decrease in discrimination will lengthen the horizontal portion of the demand curve and reduce the slope of the downward sloping portion.
This will raise the black-white wage ratio.
The size of the black-wage gap varies directly with the supply of black labor.
If the supply of black labor is small that it intersected the horizontal portion on the demand curve, then no wage gap would exist.
14-23

24. 6/15/2018
Winners and Losers
White workers gain since they are protected from competition from black workers.
Black workers lose since they receive lower wages.
Employers that discriminate lose since they incur higher wage costs than if they did not discriminate.
Competition will decrease discrimination as lower cost non-discriminating firms will drive discriminating firms out of business.
14-24

25. Worker and Customer Discrimination
Assume some workers of a group are discriminating against b group and require a premium to work with them. Similar to the case above and leads to segregation.
Assume customer discriminate against b workers and get lower utility for the services they receive from b workers. In this case no arbitrage because customers bear the cost of discrimination.

4. Theory of Statistical Discrimination
14-26

27. Statistical Discrimination
6/15/2018
Statistical Discrimination
Statistical discrimination exists when employers base decisions upon the average characteristics of the group to which they belong.
Ex: Young males pay higher insurance rates since they have more accidents on average.
Employers base hiring decisions on imperfect predictors of productivity.
Age, education, and experience provide some information about productivity.
14-27

28. Statistical Discrimination
6/15/2018
Statistical Discrimination
Employers may use race and gender as well since they also provide information.
Gender may provide information on job commitment since women on average have higher turnover rates.
Race may provide some information about schooling quality since blacks on average go to inferior schools than whites.
14-28

29. 6/15/2018
Implications
Employers are not harmed when they practice statistical discrimination.
They gain since they minimize hiring costs.
Employers are not being malicious in practicing this type of discrimination.
The problem is that workers who have characteristics different from the average are harmed.
Statistical discrimination will diminish if the average characteristics of the groups converge over time.
Male-female turnover rates are converging.
14-29

30. 6/15/2018
Question for Thought
1. Explain the following statement: “In the taste-for-discrimination model, discrimination is practiced even though it is costly to do so. But in the statistical discrimination model, it is clear that discrimination pays.”

By crowding women into a narrow set of “female” occupations, men will receive high wage rates of Wm in male occupations, while women will receive low wage rates of Wf in female occupations.
Employers may practice job segregation if male (white) workers don’t like to work with female (black) workers.
14-32

33. Ending Discrimination
6/15/2018
Ending Discrimination
Ending occupational crowding would enable females to enter male occupations.
Raise the wage rates of women and lower the wage rates of men
There would be a net gain to society as domestic output and efficiency would increase.

34. Index of Occupational Segregation by Gender
6/15/2018
Index of Occupational Segregation by Gender
The index of segregation shows the percentage of women (men) who would have to change occupations for women to be distributed among occupations in the same proportions as men.
The index of segregation by gender has fallen moderately over time.

6. Cause and Effect: Nondiscriminatory Factors
14-36

37. 6/15/2018
Rational Choice
Some economists argue that part of the gender wage gap is the result of rational choices made by women.
Women tend to have interrupted work careers due to childbearing.
Due to their shorter work careers, it is rational for women to invest less in education and training.
Their stock of human capital will deteriorate while they are out of the labor force.
Occupational segregation may be due to women choosing occupations, such as nursing and teaching, with skills that are useful in home production.
14-37

38. 6/15/2018
Rational Choice
The wage gap may be the result of compensating wage differentials.
Women may prefer safer jobs, less effort-intensive jobs, and shorter commute times.
Women work fewer hours than men.
More likely work part-time
Full-time women work fewer hours than full-time men.
14-38

39. Discrimination as a Cause
6/15/2018
Discrimination as a Cause
Some argue that women invest less in human capital because of discrimination.
Women stay out of the labor force because of the low pay in the labor market.
If discrimination declined, then more women may decide to remain single or childless.
Sexual harassment may cause women to drop out of the labor force.
14-39

40. Evidence Male-female pay gap
6/15/2018
Evidence
Male-female pay gap
Researchers decompose the pay gap into the portion explained by differences in productivity characteristics and the portion unexplained (discrimination).
Blau-Kahn find that two-thirds of the pay gap can be explained by differences in experience, industry, occupation, etc.
Pay gap has been falling equally due to a rise in relative productivity characteristics of women and a decline in the unexplained gap.
14-40

41. Evidence Black-white pay gap
6/15/2018
Evidence
Black-white pay gap
Blau-Kahn find that 89 percent of the pay gap can be explained by differences in productivity characteristics.
The pay gap has not changed much over time.
The black-white difference in education has diminished and thus shrunk the gap.
The payoff to education has risen which has expanded the gap.
14-41

42. 6/15/2018
Controversy
Economists differ on whether the unexplained portion over or understates the amount of discrimination.
Economists differ on whether unobserved productivity characteristics favor men or women.
Do the observed productivity characteristics (such as occupation) reflect discrimination?
14-42

43. 6/15/2018
Question for Thought
1. “Wage differences between men and women do not reflect discrimination but rather differences in job continuity and rational decisions with respect to education and on-the-job training.” Explain why you agree or disagree.

7. Antidiscrimination Policies and Issues
14-44

45. 6/15/2018
Equal Pay Act of 1963
The Equal Pay Act of 1963 requires that men and women doing the same job be paid the same.
Firms could avoid the law’s requirements by conducting employment discrimination (e.g., not hiring females for jobs held by males) .
14-45

46. 6/15/2018
Civil Rights Act of 1964
The Civil Rights Act of 1964 outlaws both wage discrimination and employment discrimination.
Applies to race, gender, color, religion, and national origin
Applies to private employers, labor unions, and governments
14-46

47. 6/15/2018
Executive Orders
Executive orders in 1965 and 1968 attempted to eliminate discrimination by businesses holding government contracts.
Firms with more than $50,000 of government contracts must develop affirmative-action programs.
Firms must develop a plan to hire more women and minorities if the firm has a smaller of proportion of women and minorities than in the available labor force.
These programs have been under legal and political attack.
14-47

48. Controversy Interventionist view
6/15/2018
Controversy
Interventionist view
The market has failed to eliminate discrimination.
Minorities and women have been discriminated against in the acquisition of human capital.
Current legislation against discrimination does not correct for the effects of past discrimination.
More than equal opportunity must be given to close the current gap.
14-48

49. Have Anti-Discrimination Policies Worked?
6/15/2018
Have Anti-Discrimination Policies Worked?
The empirical evidence on whether government policies have narrowed the gender and racial pay gaps is mixed.
It is difficult to separate the effects of the laws from other factors that are changing.
The affirmative-action laws did appear to have improved the employment opportunities for women and minorities in the 1970s but this progress ended in the 1980s.
