The incidence of Cesarean deliveries (CDs) has been on the rise. The procedure's cost and benefits are discussed controversially; in particular, since non-medically indicated cases seem widespread. We study the effect of CDs on subsequent fertility and maternal labor supply. Identification is...

In this study we examine the passage of a reform to in-vitro fertilization (IVF) procedures in Sweden in 2003. Following publication of medical evidence showing that pregnancy success rates could be maintained using single rather than multiple embryo transfers, the single embryo transfer (SET)...

We provide a novel interpretation of the estimated treatment effects from evaluations of parental leave reforms. Accounting for the counterfactual mode of care is crucial in the analysis of child out-comes and potential mediators. We evaluate a large and generous parental leave extension in...

Tougher immigration enforcement has been responsible for approximately 1.8 million deportations between 2009 and 2013 alone. Children enter the foster care system when their parents are apprehended, deported and unable to care for them. We find that the average increase in interior immigration...

We model the bargaining process of parents over custody at the time of divorce. First we assume an institutional setting where only sole custody is available. In a second step we reform this institutional setting and introduce the possibility of joint custody. We show that some parents, who...

Maternity leave policies are presumed to be essential to ensure the health of pregnant workers and their unborn children. However, little is known about the optimal duration of prenatal maternity leave and existing policies are not evidence-based. We evaluate a substantial maternity leave...

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...

We evaluate three policy reforms targeted at older unemployed people: (i) an hourly wage subsidy, (ii) an in-work credit, and (iii) a subsidy of social security contributions on low wages. The work incentive, labour supply and welfare effects of these hypothetical reforms are analysed on the...
