Fortunate Families?
利用瑞典彩票中奖者的数据，研究正向财富冲击对婚姻和生育的影响，发现男性中奖后结婚和生育增加，女性中奖后短期离婚风险上升，结果与性别差异的消费偏好模型一致。
<h3>Abstract</h3> We estimate the effects of large, positive wealth shocks on marriage and fertility among Swedish lottery players. For male winners, wealth increases marriage formation and fertility and likely reduces divorce risk. For female winners, the only clear effect is a higher short-run (but not long-run) divorce risk. The gendered treatment effects are often similar to income gradients. Our findings align with models in which wives derive greater marginal utility from consumption when single than when married, whereas the opposite holds for husbands—but only if marital property is divided unequally upon divorce. We provide descriptive evidence consistent with such unequal division.
