Intertemporal Labor Supply and the Distribution of Family Income
利用PSID面板数据发现，已婚女性劳动供给的跨期波动使夫妻终身收入相关性低于年度收入，从而降低终身不平等；终身潜在收入不平等远大于年均收入。
The earnings of married women have a more equalizing effect on the distribution of lifetime family earnings (or the expected present value of earnings) than on the distribution of annual family earnings, using Panel Study of Income Dynamics longitudinal data. The intertemporal variability of wives' labor supply causes the correlation between the lifetime earnings of husbands and wives to weaken relative to the correlation between their annual incomes, resulting in lower lifetime inequality. The inequality of potential income (full employment earnings) is found to be much greater for lifetime earnings than average annual earnings, based on alternative endogenous wage-hours models.
