Discrimination in the Marketplace: A Model

25 April, 2016 - 09:12

Discrimination occurs when people with similar economic characteristics experience different economic outcomes because of their race, sex, or other noneconomic characteristics. A black worker whose skills and experience are identical to those of a white worker but who receives a lower wage is a victim of discrimination. A woman denied a job opportunity solely on the basis of her gender is the victim of discrimination. To the extent that discrimination exists, a country will not be allocating resources efficiently; the economy will be operating inside its production possibilities curve.

Pioneering work on the economics of discrimination was done by Gary S. Becker, an economist at the University of Chicago, who won the Nobel Prize in economics in 1992. He suggested that discrimination occurs because of people’s preferences or attitudes. If enough people have prejudices against certain racial groups, or against women, or against people with any particular characteristic, the market will respond to those preferences.

In Becker’s model, discriminatory preferences drive a wedge between the outcomes experienced by different groups. Discriminatory preferences can make salespeople less willing to sell to one group than to another or make consumers less willing to buy from the members of one group than from another r to make workers of one race or sex or ethnic group less willing to work with those of another race, sex, or ethnic group.

Let us explore Becker’s model by examining labor-market discrimination against black workers. We begin by assuming that no discriminatory preferences or attitudes exist. For simplicity, suppose that the supply curves of black and white workers are identical; they are shown as a single curve in Figure Figure 19.8. Suppose further that all workers have identical marginal products; they are equally productive. In the absence of racial preferences, the demand for workers of both races would be D. Black and white workers would each receive a wage W per unit of labor. A total of L black workers and L white workers would be employed.

Now suppose that employers have discriminatory attitudes that cause them to assume that a black worker is less productive than an otherwise similar white worker. Now employers have a lower demand, DB, for black than for white workers. Employers pay black workers a lower wage, WB, and employ fewer of them, LB instead of L, than they would in the absence of discrimination.

If employers, customers, or employees have iscriminatory preferences, and those ferences are widespread, then the marketplace will result in discrimination. Here,black workers receive a lower wage and fewer of them are employed than would be the case in the absence of discriminatory preferences
