The impact of children's early development status on parental labor market outcomes is not well established in the empirical literature. We combine an instrumental variable approach to account for the endogeneity of the development status with a model of non- random labor force participation to identify its impact. A one unit increase in our poor child development index reduces long-term maternal weekly hours worked by 9 hours and weekly income by 215 Australian Dollars. We provide evidence that mothers substitute working time with childcare to compensate for early disadvantages. We do not find any responds of fathers to early child development.

儿童早期发展与父母的劳动力供给

儿童早期发育状况对父母劳动力市场结果的影响在实证文献中并未得到很好的证实。我们将解释发展状况内生性的工具变量方法与非随机劳动力参与模型相结合，以确定其影响。我们的儿童发育不良指数每增加一个单位，长期孕产妇每周工作时间就会减少 9 小时，每周收入会减少 215 澳元。我们提供的证据表明，母亲以育儿代替工作时间，以弥补早期的不利条件。我们没有发现父亲对儿童早期发展的任何反应。
