样本选择模型的参数与半参数估计:葡萄牙女性劳动力的实证应用
Abstract This paper applies both parametric and semiparametric methods to the estimation of wage and participation equations for married women in Portugal. The semiparametric estimators considered are the two‐stage estimators proposed by Newey ( 1991 ) and Andrews and Schafgans ( 1998 ). The selection equation results are compared using the specification tests proposed by Horowitz ( 1993 ), Horowitz and Härdle ( 1994 ), and the wage equation results are compared using a…
