This paper investigates the potential of an infant intervention to improve life expectancy, contributing to emerging interest in the early life origins of chronic disease. We analyse a pioneering program trialled in Sweden in the 1930s, which provided information, support and monitoring of...

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)...

Twin births are often construed as a natural experiment in the social and natural sciences on the premise that their occurrence is quasi-random. We present new population-level evidence challenging this premise. Using data on about 18 million births in 72 countries, we find that maternal...

We investigate the importance of subjective expectations of returns to and effort costs of the two main investments that mothers make in newborns: breastfeeding and stimulation. We find heterogeneity across mothers in expected effort costs and expected returns for outcomes in the cognitive,...

We evaluate the long-term impact of treating maternal depression on women’s financial empowerment and parenting decisions. We leverage experimental variation induced by a cluster-randomized control trial that provided psychotherapy to perinatally depressed mothers in rural Pakistan. It was one...

Raising women's political participation leads to faster maternal mortality decline. We estimate that the introduction of quotas for women in parliament results in a 9 to 12% decline in maternal mortality. In terms of mechanisms, it also leads to an 8 to 11% increase in skilled birth attendance...

Raising women's political participation leads to faster maternal mortality decline. We estimate that the introduction of quotas for women in parliament results in a 9-12 per cent decline in maternal mortality. In terms of mechanisms, it also leads to an 8-11 per cent increase in skilled birth...

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 investigate universalization of access to health in Brazil. We find large reductions in maternal, foetal, neonatal and post-neonatal mortality, a reduction in fertility and, possibly on account of selection, no change in the quality of births. Using rich administrative data, we investigate...
