Abstract

Time diaries of sibling pairs from the PSID-CDS are used to determine whether maternal time investments compensate for or reinforce birth-weight differences among children. The findings demonstrate that the direction and degree of differential treatment vary by mother's education. Less-educated mothers devote more total time and more educationally oriented time to heavier-birth-weight children, whereas better-educated mothers devote more total and more educationally oriented time to lower-birth-weight children. The compensating effects observed among highly educated mothers are substantially larger than the reinforcing effects among the least-educated mothers. The findings show that families redistribute resources in ways that both compensate for and exacerbate early-life disadvantages.

摘要

PSID-CDS 的兄弟姐妹时间日记被用来确定母亲的时间投入是否弥补或加剧了孩子之间的出生体重差异。研究结果表明,这种差异对待的方向和程度因母亲的教育程度而异。受教育程度较低的母亲会给出生体重较重的孩子投入更多的总时间和更注重教育的时间,而受教育程度较高的母亲则会给出生体重较低的孩子投入更多的总时间和更注重教育的时间。在高学历母亲中观察到的补偿效应明显大于在受教育程度最低的母亲中观察到的强化效应。研究结果表明,家庭以既能弥补又能加剧生命早期劣势的方式重新分配资源。
