Can barely winning lead to losing? Gender and past performance
利用职业网球数据，研究发现女性在经历接近的失利后表现显著变差，而男性则不受影响，揭示了性别在负面心理动量上的差异。
We use high-volume data from professional tennis to estimate the causal effect of past on current performance for women and men. To identify this effect, we exploit double faults as exogenous shocks to past performance. We estimate that men do not react to near setbacks in the past. In contrast, women perform considerably worse after near setbacks. Heterogeneity analysis reveals different effects depending on experience, ability, and the intermediate score. Our results are robust to a number of sensitivity checks. A potential explanation for our findings are gender differences in negative psychological momentum.
