This paper examines the effect of economic incentives generated by U.S. divorce and custody law on a range of child health and human capital measures. State laws vary widely in the treatment of child support under joint custody. While some states require no child support in joint custody cases,...

It is well known that children reared in non-intact families on average have less favorable educational outcomes than children reared in two-parent families. Evidence from the United States and Sweden indicates that living in a non-intact family is correlated with lower educational attainment....

We study the effect of a policy change that exogenously shifted bargaining power from mothers to fathers on intimate partner violence. We exploit a quasi-natural experiment based on a series of reforms in Spain that shifted the custody decision from being unilaterally determined by the mother to...

Twin births are often construed as a natural experiment in the social and natural sciences on the premise that the occurrence of twins is quasi-random. We present new population-level evidence that challenges this premise. Using individual data for 17 million births in 72 countries, we...

Twin births are often used to instrument fertility to address (negative) selection of women into fertility. However recent work shows positive selection of women into twin birth. Thus, while OLS estimates will tend to be downward biased, twin-IV estimates will tend to be upward biased. This is...

Twin births are often construed as a natural experiment in the social and natural sciences on the premise that the occurrence of twins is quasi-random. We present new population-level evidence that challenges this premise. Using individual data for more than 18 million births (more than 500,000...

We analyze the impact on schooling outcomes of growing up in a family headed by a single mother. Growing up in a non-intact family in Germany is associated with worse outcomes in models that do not control for possible correlations between common unobserved determinants of family structure and...
