We examine the effects of an increase in income on the cohabitation and marriage of single mothers. Using data from an experiment that resulted in randomly assigned differences in child support receipt for welfare-receiving single mothers, we find that exogenous income increases (as a result of receiving all child support that was paid) are associated with significantly lower cohabitation rates between mothers and men who are not the fathers of their child(ren). Overall, these results support the hypothesis that additional income increases disadvantaged women's economic independence by reducing the need to be in the least stable type of partnerships. Our results also show the potential importance of distinguishing between biological and social fathers.
我们考察了收入增加对单身母亲同居和结婚的影响。利用一项实验的数据，该实验导致接受福利的单身母亲获得的子女抚养费出现随机差异，我们发现，外在收入增加（由于收到所有应付的子女抚养费）与母亲与非子女生父之间的同居率显著降低有关。总体而言，这些结果支持了这样一种假设，即额外收入通过减少对最不稳定类型的伴侣关系的需求，增加了弱势妇女的经济独立性。我们的结果还表明，区分生物学和社会意义上的父亲可能具有重要意义。
