Self‐employment among women: Do children matter more than we previously thought?
提出一种估计方法，同时处理样本选择和生育决策的内生性问题，发现忽略这些偏差会低估年幼子女对女性自雇的影响，修正后影响约增大三倍。
Summary This paper presents an estimation approach that addresses the problems of sample selection and endogeneity of fertility decisions when estimating the effect of young children on women's self‐employment. Using data from the National Longitudinal Survey of Youth 1979, 1982–2006, we find that ignoring self‐selection and endogeneity leads to underestimating the effect of young children. Once both sources of biases are accounted for, the estimated effect of young children roughly triples when compared to uncorrected results. This finding is robust to several changes in the specification and to the use of a different dataset.
