Using Michigan Panel Study of Income Dynamics (PSID) data, we study the slowdown in the convergence of female and male wages in the 1990s compared to the 1980s. We find that changes in human capital did not contribute to the slowdown, since women’s relative human capital improved comparably in the two decades. Occupational upgrading and deunionization had a larger positive effect on women’s relative wages in the 1980s, explaining a portion of the slower 1990s convergence. However, the largest factor was that the “unexplained” gender wage gap fell much faster in the 1980s than the 1990s. Our evidence suggests that changes in labor force selectivity, changes in gender differences in unmeasured characteristics and in labor market discrimination, as well as changes in the favorableness of demand shifts each may have contributed to the slowing convergence of the unexplained gender pay gap.

Using a large sample of establishments drawn from the Multi-City Study of Urban Inequality (MCSUI) employer survey, we study gender differences in promotion rates and in the wage gains attached to promotions. Several unique features of our data distinguish our analysis from the previous literature on this topic. First, we have information on the wage increases attached to promotions, and relatively few studies on gender differences have considered promotions and wage increases together. Second, our data include job-specific worker performance ratings, allowing us to control for performance and ability more precisely than through commonly-used skill indicators such as educational attainment or tenure. Third, in addition to standard information on occupation and industry, we have data on a number of other firm characteristics, enabling us to control for these variables while still relying on a broad, representative sample, as opposed to a single firm or a similarly narrowly-defined population. Our results indicate that women have lower probabilities of promotion and expected promotion than do men but that there is essentially no gender difference in wage growth with or without promotions.
