Many economists have tried to explain existing wage differentials between men and women. A new approach compares the relative importance of occupational discrimination with that of wage discrimination. This model allows for variation both in occupational distribution and in wages resulting from differences in job qualifications and productivity indicators. It was demonstrated that the usual approach to wage discrimination is a special case of this general model with some restrictive implicit assumptions. A multinomial logit model was used to stimulate the occupational distribution of women that would exist if they faced the same structure of occupational determination as men. Results indicate that there would be more women in managerial and skilled labor jobs and fewer women clerical and service workers. Wages were then estimated as a function of productivity measures for men and women in each occupation so that the components of the wage differential could be calculated. Results indicate that almost the entire differential could be eliminated by ending both forms of discrimination, with occupational discrimination accounting for one-third to one-half of the differential and pure wage discrimination the remainder.
