Children's Health and Maternal Work Activity: Estimates under Alternative Disability Definitions
利用SIPP面板数据，研究不同儿童残疾定义对母亲（包括已婚女性和女性户主）市场劳动的影响，发现儿童残疾对女性户主和妻子的就业及工时均有负面效应，但对女性户主的工时增长和就业进入有不利影响，而对妻子则无类似证据。
Past empirical findings indicate that children’s health problems reduce married mothers’ employment but are inconclusive in the case of female heads. These studies use diverse disability definitions, samples, and specifications. This paper uses pooled SIPP panels to investigate the impact of alternative disability measures on maternal market work. Negative effects of several disability definitions on female heads’ and wives’ employment and hours at a point in time are found. In contrast, while female heads’ growth in work hours over time and probabilities of entering employment appear adversely affected by child disability, there is no evidence for analogous effects on wives.
