旨在减少家庭间不平等的经济激励是否加剧了家庭内部不平等?

Do financial incentives aimed at decreasing interhousehold inequality increase intrahousehold inequality?

中文摘要

已有研究表明,向弱势家庭提供投资子女的经济激励,可能通过促进人力资本形成来降低社会经济不平等。然而,这种收益在家庭内部是如何实现的?我们利用田野实验考察父母在获得经济激励时如何配置时间。我们发现,激励增加了对目标儿童的投入,但父母是通过挤占陪伴该儿童兄弟姐妹的时间来实现这些收益的。一个意料之外的后果是,家庭内部不平等加剧,而且若仅关注目标儿童,该项目带来的总体收益会被高估。

Abstract

Research has shown that giving disadvantaged families financial incentives to invest in their children could decrease socioeconomic inequality by enhancing human capital formation. Yet, within the household how are such gains achieved? We use a field experiment to investigate how parents allocate time when they receive financial incentives. We find that incentives increase investment in the target child. But, parents achieve these gains by substituting away from time spent with the child’s sibling(s). An unintended consequence is that intrahousehold inequality increases and aggregate gains from the program are overstated when focusing only on target children.
