To Work or Not to Work? Child Development and Maternal Labor Supply
研究早期儿童发展对母亲劳动参与的影响，发现儿童发展不良每增加一个单位，母亲劳动参与率下降约10个百分点，对劳动经济学和家庭政策研究者有参考价值。
We estimate the effect of early child development on maternal labor force participation. Mothers of poorly developing children may remain at home to care for their children. Alternatively, mothers may enter the labor force to pay for additional educational and health resources. Which action dominates is the empirical question we answer in this paper. We control for the potential endogeneity of child development by using an instrumental variables approach, uniquely exploiting exogenous variation in child development associated with child handedness. We find that a one unit increase in poor child development decreases maternal labor force participation by approximately 10 percentage points.
