Employment Discrimination

Earnings Gaps by Race and Gender

A possible signal of labor market discrimination is when one group is paid less than another. Figure 1 shows the average wage of black workers as a ratio of the average wage of white workers and the average wage of female workers as a ratio of the average wage of male workers. Research by the economists Francine Blau and Laurence Kahn shows that the gap between the earnings of women and men did not move much in the 1970s, but has declined since the 1980s. According to the U.S. Census, the gap between the earnings of blacks and whites diminished in the 1970s, but has not changed in 50 years. In both gender and race, an earnings gap remains.

**Figure 1.** Wage Ratios by Sex and Race. The ratio of wages for black workers to white workers rose substantially in the late 1960s and through the 1970s, but has not changed much since then. The ratio of wages for female to male workers changed little through the 1970s, but has risen substantially since the 1980s. In both cases, a gap remains between the average wages of black and white workers and between the average wages of female and male workers.

An earnings gap between average wages, in and of itself, does not prove that discrimination is occurring in the labor market. We need to apply the same productivity characteristics to all parties (employees) involved. Gender discrimination in the labor market occurs when women are paid less than men despite having comparable levels of education, experience, and expertise. (Read the Clear It Up about the sex-discrimination suit brought against Wal-Mart). Similarly, racial discrimination in the labor market exists when racially diverse employees are paid less than their coworkers of the majority race despite having comparable levels of education, experience, and expertise. To bring a successful gender discrimination lawsuit, a female employee must prove that she is paid less than a male employee who holds a similar job, with similar educational attainment, and with similar expertise. Likewise, someone who wants to sue on the grounds of racial discrimination must prove that he or she is paid less than an employee of another race who holds a similar job, with similar educational attainment, and with similar expertise.
