The Effect of Marital Breakup on the Income Distribution of Women with Children
利用头胎为女孩作为外生变量，发现离婚虽不影响女性平均家庭收入，但增加了收入极端化的概率，即部分女性成功弥补损失，而另一些则陷入贫困，从而加剧了不平等。
Having a female first-born child significantly increases the probability that a woman's first marriage breaks up. Using this exogenous variation, recent work finds that divorce has little effect on women's mean household income. We further investigate the effect of divorce using Quantile Treatment Effect methodology and find that it increases women's odds of having very high or very low income. In other words, while some women successfully compensate for lost spousal earnings through child support, welfare, combining households, and increasing labor supply, others are markedly unsuccessful. We conclude that by raising both poverty and inequality, divorce has important welfare consequences.
