Retirement coordination and leisure complementarity
研究发现夫妻退休时间相近并非源于休闲互补，而是由收入平等和休闲效用差异驱动，对理解家庭退休决策有参考价值。
Empirical evidence suggests that in a large fraction of working couples spouses retire within a short period of time. This retirement coordination is frequently attributed to leisure complementarities. Contrary to this view, I find strong substitutability between the leisure of the two household members. Using a dynamic programming model of optimal retirement and labor supply decisions, I further show that high levels of retirement coordination can be observed even in the absence of leisure complementarity. Retirement coordination is higher in the households with more equality in the earnings profiles and utility derived from the leisure of their individual members.
