Gender Differences in Promotions and Wages
基于原始数据集发现女性晋升次数多于男性，但晋升对男性工资提升显著，对女性不显著，这与联合求职迫使女性从较低职位起步从而有更多晋升空间的观点一致。
Results using an original data set indicate women receive more promotions than men. The frequency of promotions is linked to whether the woman had previously quit a job because of her husband's job move. Promotions significantly increase wages for men but not for women. These findings are consistent with the hypothesis that joint job search constrains women to starting jobs at lower levels, providing more scope for promotions.
