We consider the division of caregiving efforts among the children of older, functionally limited parents. Our model of parental care assumes that care decisions are made in the context of an extended family, with each child taking into account not only the parent's needs and the child's own circumstances, but also the characteristics and actual care behavior of siblings. We propose a simultaneous-Tobit statistical framework that embodies these assumptions. The model is estimated using data from the 1993 Asset and Health Dynamics Among the Oldest Old (AHEAD) study. The findings indicate that a child's hours of parent care are reduced, but on much less than a one-for-one basis, as the parent-care hours of siblings increase. We also find that a child's supply of parent-care hours is reduced by having sisters, holding constant the care efforts of siblings.
我们研究了年长且功能受限的父母的子女之间照顾责任的分配情况。我们的父母照顾模型假设，照顾决策是在大家庭背景下做出的，每个孩子不仅要考虑父母的需求和自己的情况，还要考虑兄弟姐妹的特征和实际照顾行为。我们提出了一个体现这些假设的联立Tobit统计框架。该模型使用1993年老年资产与健康动态研究（AHEAD）的数据进行估计。研究结果表明，随着兄弟姐妹照顾父母时间的增加，孩子照顾父母的时间会减少，但减少幅度远小于一对一的比例。我们还发现，在兄弟姐妹照顾努力不变的情况下，有姐妹会减少孩子提供的照顾父母的时间。
