Abstract

Why do U.S. college-educated couples with children marry at higher rates than those without a college degree? We argue that investing in children is more valuable for college-educated couples, who are more likely to send their children to college. Marriage, which entails lower separation risk and more equal asset division if separation does occur, provides insurance to the lower-earning spouse, which facilitates child investment. Using an OLG model of marriage, cohabitation, wealth accumulation, and educational investments where college completion is risky, we find that insurance through marriage is particularly important when investing in children is costly and college costs are high.
