Recent Two-Stage Sample Selection Procedures With an Application to the Gender Wage Gap
使用1989年劳动力市场活动调查数据，应用新发展的两阶段样本选择模型，分析男女劳动供给决策和工资结果，检验样本选择问题并比较参数与半参数方法，最后分解性别工资差距。
Recently developed two-stage estimation methods of sample selection models are used, in the context of data from the 1989 Labor Market Activity Survey, to examine labor supply decisions and wage outcomes for employed men and women. Recent hypothesis test procedures are used to test for no sample selection and to test for a parametric against a semiparametric selection-correction procedure. We conclude that selection is indeed an issue for the sample at hand and that the semiparametric specification is appropriate. We also present the standard decomposition of the gender wage gap into its explained and unexplained portions.
