劳动力市场选择对性别工资差距的影响

中文摘要

利用密歇根收入动态面板研究（PSID）数据，我们研究了选择性偏误与性别工资差距。采用多种方法，我们发现1981年至2015年间工资出价的总体性别差距与未解释性别差距大幅下降。在我们偏好的选择性纠正方法下，总体差距与未解释差距的中位数分别下降了0.378个对数点和0.204个对数点。这一降幅大于不纠正选择性、仅测算可观测工资差距收敛幅度时所得到的结果。然而，2015年经选择性纠正后的中位数性别工资差距仍然可观：总体差距为0.242个对数点，未解释差距为0.206个对数点。

Abstract

Using Michigan Panel Study of Income Dynamics data, we study selection bias and the gender wage gap. Employing several methods, we find large declines in the total and unexplained gender gaps in wage offers between 1981 and 2015. Under our preferred selection correction method, the median total and unexplained gaps fell by 0.378 and 0.204 log points, respectively. These are larger declines than if we had not corrected for selection and simply measured convergence in observed wage gaps. However, substantial selectivity-corrected median gender wage gaps remain in 2015: 0.242 log points (total gap) and 0.206 log points (unexplained gap).
