Early Maternal Time Investment and Early Child Outcomes
利用英国千禧队列研究数据，估计母亲时间投入对儿童早期技能形成的影响，发现其效应随儿童年龄增长而下降，且早期投入对认知发展有长期影响。
Using large longitudinal survey data from the UK Millennium Cohort Study, this article estimates the relationship between maternal time inputs and early child development. We find that maternal time is a quantitatively important determinant of skill formation and that its effect declines with child age. There is evidence of long‐term effects of early maternal time inputs on later outcomes, especially in the case of cognitive skill development. In the case of non‐cognitive development, the evidence of this long‐term impact disappears when we account for skill persistence.
