Health status and the allocation of time
基于美国时间利用调查数据，研究发现健康状况越好，市场生产和家庭生产时间越多，但休闲时间越少，且这种关联在单身人群中比已婚人群更强。
We consider the relationship between health and time allocation in the American Time Use Survey. Better health is associated with large positive effects on home production and larger positive effects on market production, but less consumption of leisure. Theoretically, if market- and home-produced goods are perfect substitutes, the positive correlation between health and home production implies that health exerts larger effects on home than on market efficiency. Notably, these correlations are higher for single people than for married people, perhaps reflecting a lack of market substitutes for the time of married people.
