“…Many studies report that the proportion of men in an occupation has a significant, positive relation with wages (e.g., Johnson and Solon, 1987;England et al, 1988;Sorensen, 1990;Groshen, 1991;Macpherson and Hirsch, 1995), 1 and researchers offer a variety of explanations for the pay disparity between female-and male-dominated occupations, such as discrimination, job-specific differences in productivity, and compensating differentials. 2 Research indicates that the positive relation between the proportion male in an occupation and wages is reduced, but still persists, when the wage equation controls for the job-characteristics.…”
