Trends in Earnings Differentials by Gender,1971–1981

Abstract

Using data from the Current Population Surveys, the authors examine earnings differentials by gender for 1971 and 1981. Most observers, focusing on the median annual earnings of year-round, full-time workers, have concluded that the earnings differential did not change over that decade. Using a different method to adjust for gender differences in hours and weeks worked, the authors find, on the contrary, that the female-male earnings ratio significantly increased during the 1970s. The results suggest that declining gender role specialization and declining discrimination (as conventionally measured) contributed to the observed trend. Two factors that worked in the opposite direction, though to smaller effect, were declines in women's relative returns to education and to employment in male jobs and integrated jobs.
