Trapped at home: The effect of mothers' temporary labor market exits on their subsequent work career
利用挪威1998年引入的“现金换照料”项目，研究母亲因照顾幼儿暂时退出劳动力市场对后续收入及全职就业的影响，发现对低学历或低收入母亲的影响在儿童4-5岁时仍存在，但到6岁后消失。
This paper investigates how mothers' decision to stay at home with young children affects their subsequent work careers. Identification is based on the introduction of the Cash-for-Care program in Norway in 1998, which increased mothers' incentives to withdraw from the labor market when their child was one and two years old. Our estimates demonstrate that, for mothers without a university degree or with pre-reform earnings below the median, the program had effects on earnings and full-time employment even when the child was no longer eligible for Cash-for-Care at ages four and five. However, from age six, we can no longer see any effects. Further analysis suggests that the effects dissipate because most mothers remained attached to the labor force through part-time employment.
