The average woman is less competitive than the average man: she is less likely to describe herself as competitive and less willing to enter a competition. In the workplace, this difference translates to performance; recent research by economists and political scientists indicates that competitive people do better socioeconomically. For example, among graduates of a top MBA program, the gender difference in competitiveness accounted for 10% of the gender gap in earnings 9 years after graduation; among female and male economists in France it accounted for 76% of the promotion gap.
