Do parental time investments react to changes in child’s skills and health?
利用澳大利亚儿童纵向研究数据，采用儿童固定效应工具变量法，发现父母会因孩子高社交情感技能而增加社交时间，因低认知技能而增加学习活动时间。
Parental time investment decisions have been found to have important effects on child development; however, little is known about the response of parents to changes in their child’s human capital across time. Using the Longitudinal Study of Australian Children, we measure time investments considering the time young children spend, with or without parents, in different activities. By adopting a child fixed-effect instrumental variable estimation, we find that parents reinforce for high socio-emotional skills by spending more time socialising with their child and compensate for low cognitive skills by increasing the time the child spends in learning activities.
