This study concerns the relationship between gender and job performance among
brokerage firm equity analysts. Women’s representation in analyst
positions dropped from 16 percent in 1995 to 14 percent in 2005. The study found
significant gender-based differences in performance on various dimensions. For
example, women cover roughly 9 stocks, on average, as compared with 10 for men,
and women’s earnings estimates tend to be less accurate than men’s
estimates. But the study also found that women are significantly more likely
than men to be designated as All-Stars, which indicates that they outperform men
in other aspects of job performance.
