Worker Displacement and the Added Worker Effect
研究妻子在丈夫失业前后的劳动供给变化，发现失业后妻子劳动供给大幅且持久增加，长期可弥补丈夫超过25%的收入损失。
This article examines the "added worker effect, " which is the labor supply response of wives to their husbands' job losses. Unlike past studies, which focused on the husbands' current unemployment status, this article analyzes wives' responses before and after job losses to examine the life-cycle labor supply adjustments. Using Panel Study of Income Dynamics data reveals small predisplacement effects and large, persistent postdisplacement effects. The timing of the responses differs with type of displacement, possibly because of differences in the information acquired before job loss. Long-run labor supply increases compensate for over 25% of the husbands' lost income.
