“God, what gorgeous staff I have. I just can’t understand those who have ugly people

working for them, I really can’t. Just call me a pathetic

aesthetic.”

Introduction

• Discrimination occurs when the marketplace takes into account such factors as race and sex when making economic exchanges.

Page 3: CHAPTER 9

9-3

Race and Genderin the Labor Market

• Men earn more than women, and whites usually earn more than nonwhites.

• Differences in educational attainment between whites and nonwhites account for a portion of the wage differential.

Page 4: CHAPTER 9

9-4

The Discrimination Coefficient

• Taste discrimination translates the notion of racial prejudice.

oRacial prejudice causes employers to blindly perceive the costs of hiring blacks as being higher than the true cost.

oEven though it costs wb dollars to hire one person-hour of black labor, the employer acts as if it costs wb(1+d) dollars, where d, d>0, is the discrimination coefficient.

Page 5: CHAPTER 9

9-5

Employer Discrimination• Implication of the Becker model• If blacks and whites are perfect substitutes,

employers have a segregated work force.o Even non-discriminating employers have a segregated work force,

as they employ all black workers

• Discrimination does not pay.o Employers hire the wrong type of worker and/or they hire the wrong

number of workers.

The Employment Decision for a Firm That Does Not Discriminate

If the market-determined black wage is less than the white wage, a firm that does not discriminate will hire only blacks. It hires black workers up to the point where the black wage equals the value of marginal product of labor, E*B. VMPE

The Employment Decision for a Prejudiced Firm

Firms that discriminate can be either white firms (if the discrimination coefficient is very high) or black firms (if the discrimination coefficient is relatively low). A white firm hires white workers up to the point where the white wage equals the value of marginal product. A black firm hires black workers up to the point where the utility-adjusted black wage equals the value of marginal product. Firms that discriminate hire fewer workers than firms that do not discriminate.

Discrimination reduces profits in potentially two ways. A discriminatory firm that hires only white workers will hire too few workers at a very high wage. Even a discriminatory firm that only hires black workers is harmed by its actions as it hires too few workers.

The Black-White Wage Ratio in the Labor Market

• Employer discrimination generates a wage gap between equally skilled black and white workers.

• The quantity demanded for black labor increases as the black-while wage ratio falls.

(wB/wW)

If the black-white wage ratio is very high, no firm in the labor market will want to hire blacks. As the black-white wage ratio falls, more and more firms are compensated for their disutility and the demand for black workers rises. The equilibrium black-white wage ratio is given by the intersection of supply and demand, and equals (wB/wW)*. If some firms prefer to hire blacks, they would be willing to hire blacks even if the black-white wage ratio exceeds 1, shifting the demand curve up to D. If the supply of blacks is sufficiently small, it is then possible for the black-white wage ratio to exceed 1.

Employee Discrimination• Employee discrimination does not generate a

wage differential between equally skilled black and white workers.

• Employee discrimination does not affect the profitability of firms.

• Work places will be segregated

Page 12: CHAPTER 9

9-12

Customer Discrimination• If customers discriminate, their perceived price of a good

is utility-adjusted with a discrimination coefficient.

• When a firm cannot hide black workers, customer discrimination can have an adverse effect on black wages.

Page 13: CHAPTER 9

9-13

Statistical Discrimination• Statistical discrimination is based on treating an

individual on the basis of membership in a group and knowledge of that group’s history.

Page 14: CHAPTER 9

9-14

The Impact of Statistical Discrimination on Wages

The worker’s wage depends not only on his own test score, but also on the mean test score of workers in his racial group. (a) If black workers, on average, score lower than white workers, a white worker who gets a score of T* earns more than a black worker with the same score. (b) If the test is a better predictor of productivity for white workers, high-scoring whites earn more than high-scoring blacks, and low-scoring whites earn less than low-scoring blacks.

Measuring Discrimination• One possible measure of discrimination is the

difference in mean wages.

• A better measure would compare the wages of equally skilled workers.

• Oaxaca decomposition: a technique that decomposes the raw wage differential into a portion related to a difference in skills and a portion attributable to labor market discrimination.

Policy Application: Determinants of the White-Black Wage Ratio

• There has been an upward trend in the wages of blacks in recent years.

• This has been attributed to increases in the quality and quantity of black schooling.

• Government programs have positively affected black wages.

Blank, “Race and Gender in the Labor Market,” in Orley Ashenfelter and David Card, editors, Handbook of Labor Economics, vol. 3C, Amsterdam: Elsevier, 1999, Table 5. The log wage differential between any two groups can be interpreted as being approximately equal to the percentage wage differential between the groups.

Discrimination Against Other Groups

• Differences in wages can be linked to varying educational attainment.

• Less skilled workers earn less, just as human capital theory proposes.

• Asians tend to earn more than white, mainly due to schooling.

Policy Application: Determinants of the Male-Female Wage Ratio

• Occupational crowding has segregated women into particular occupations where the return to education is lower.

• Human capital is more profitable the longer the payoff period.

• Women are better off if they enter occupations in which their skills do not deteriorate during the years they spend in the household sector.
