Replication data for: Children and Their Parents' Labor Supply: Evidence from Exogenous Variation in Family Size

Research on the labor-supply consequences of childbearing is complicated by the endogeneity of fertility. This study uses parental preferences for a mixed sibling-sex composition to construct instrumental variables (IV) estimates of the effect of childbearing on labor supply. IV estimates for women are significant but smaller than ordinary least-squares estimates. The IV are also smaller for more educated women and show no impact of family size on husbands' labor supply. A comparison of estimates using sibling-sex composition and twins instruments implies that the impact of a third child disappears when the child reaches age 13.

针对生育对劳动供给影响的研究，往往因生育的内生性问题而变得复杂。本研究借助父母对混合性别同胞结构的偏好，构建工具变量（instrumental variables，IV）估计模型，以测算生育对劳动供给的影响效应。针对女性群体的工具变量估计结果显著，但数值小于普通最小二乘（ordinary least-squares，OLS）估计结果。受教育程度更高的女性群体对应的工具变量估计值更小，且研究未发现家庭规模对丈夫劳动供给存在显著影响。对比基于同胞性别结构与双胞胎工具变量的估计结果可知，第三胎的影响会在子女年满13岁时消失。

背景与挑战

背景概述

该数据集为研究生育对父母劳动供给影响的复制数据，采用工具变量方法解决生育内生性问题，包含1980年和1990年人口普查数据及相关分析程序。研究发现子女数量对母亲劳动供给有显著但较小的影响，且对父亲劳动供给无显著影响。
