From homemakers to breadwinners? How mandatory kindergarten affects maternal labour market outcomes
利用瑞士行政数据和断点回归设计，研究发现强制幼儿园使之前未就业母亲的就业概率提高4个百分点，但对其他母亲群体无显著影响。
Abstract The majority of Swiss children attend mandatory and cost-free kindergarten at age four. We examine the effect of this policy on maternal labour market outcomes. Using administrative data from Switzerland, we exploit the birthday cut-off for kindergarten entry in the same or in the following year and apply a non-parametric regression discontinuity design (RDD). We find that mandatory kindergarten has a statistically significant positive effect on the labour market attachment of previously non-employed mothers, increasing their employment probability by 4 percentage points. In contrast, there are no significant effects on other groups or in the total sample of mothers.
