Abstract: We study the role of wealth in the marriage contract by developing a model of the household where investments in public goods can be made at the cost of future earnings. If couples cannot commit ex ante to a sufficiently equal post-divorce allocation, specialization and public good creation will be sub-optimal. However, accumulating joint assets, which the marriage contract specifies are to be divided in the case of divorce, can reduce this problem by offering insurance to the lower earning partner. Our model demonstrates that access to this “collateralized” version of the contract will lead to more household specialization, more public goods, and a higher value of marriage. To test the model’s predictions, we use homeownership as a proxy for access to joint savings technology, since homes are particularly likely to be divided in a way that favors the lower earning partner. We use idiosyncratic variation in housing prices at the time of marriage and an instrumental variables strategy to show that quasi-exogenous variation in homeownership access leads to greater specialization. We then show that as policies made marriage and nonmarital fertility more similar in other ways, wealth has become a more important determinant of who marries. Our model and empirical results suggest wealthy individuals can access a more advantageous marriage contract, which has important policy implications.
