The Menstrual Cycle and Performance Feedback Alter Gender Differences in Competitive Choices
通过数学和词汇任务的被试内实验，发现相对绩效反馈使高能力女性更倾向竞争性薪酬、低能力男性更不倾向，并消除性别选择差异；同时发现女性在激素高期更愿竞争，但反馈后差异不显著。
We use a within-subjects experiment with math and word tasks to show that relative performance feedback moves high-ability females toward more competitive forms of compensation, moves low-ability men toward less competitive forms, and eliminates gender differences in choices. We also examine females across the menstrual cycle and find that women in the high-hormone phase are more willing to compete than women in the low-hormone phase. There are no significant differences between choices after subjects receive feedback. Thus, biological differences lead to economically significant differences, but the impact of those differences can be lowered through relative performance information.
