Sources of Earnings Inequality in the Black and White Female Labor Forces

Abstract

Earnings inequality trends and their sources from 1975 to 1986 are evaluated for two historically subordinate working groups—black and white women—using Current Population Survey data. The dual nature of women's employment, improved earnings opportunities, and continuing segregation into low-paying positions create conditions under which earnings inequality in these two groups is expected to increase. Two sources of changing inequality levels are examined to determine which better explains inequality trends: the redistribution of women across labor market positions, which should have occurred due to industrial restructuring; and changes in the rates of earnings returns to labor market positions. For both groups, changes in returns better explain positive inequality trends in the 1980s, although black women's earnings are somewhat more influenced than whites’ by their redistribution across labor market positions.
