Does custody law affect family behavior in and out of marriage?

We examine the effect of joint custody on marriage, divorce, fertility and female employment in Austria using individual-level administrative data, covering the entire population. We also use unique data obtained from court records to analyze the effect on post-divorce outcomes. Our estimates show that joint custody significantly reduces divorce and female employment rates, significantly increases marriage and marital birth rates, and leads to a substantial increase in the total money transfer received by mothers after divorce. We interpret these results as evidence against Becker-Coase bargains and in support of a mechanism driven by a resource redistribution that favors men giving them greater incentives to invest in marriage specific capital. -- divorce ; fertility ; bargaining ; intrahousehold allocations ; Austria
