Household Time Use among Older Couples: Evidence and Implications for Labor Supply Parameters*
利用HRS数据中的消费活动邮件调查，研究了老年夫妇在成员从全职工作转向不工作时的时间分配变化，发现家庭生产与休闲时间比例大致恒定，并据此估计出夫妻休闲替代弹性较大，对理解工资和税收变化如何影响家庭劳动供给有重要意义。
Using the Consumption Activities Mail Survey (CAMS) module in the HRS, we document how individual time allocations change when one or more household members transitions from full-time work to not working. We find that the ratio of home production to leisure time is approximately constant for both family members. Using a model of household labor supply to understand the implications of this finding, we conclude that the elasticity of substitution between the leisure of the two members is quite large. This elasticity plays a key role in models of household labor supply and is important for understanding how changes in relative wages and taxes affect household labor supply.
