In this study we provide evidence that historical migration flows impact present-day global health differences. The underlying theory is based on three physiological facts. First, vitamin D deficiency is directly associated with increased risk of premature death. Second, the ability of humans to...

The shared response to the COVID-19 crisis demonstrates that the vast majority of society believes human wellbeing — not economic growth — should be at the centre of policy. COVID-19 exposes the foundational role of care work, both paid and unpaid, to functioning societies and economies....

Exposure to extreme shocks in early life is found to have lasting impact in adulthood. Exploiting the variation in exposure measured by age and intensity of earthquake, we evaluate the impact of a 7.7 MW earthquake in Gujarat, India, on the health stock of children who were in utero or below...

The response of governments to the COVID-19 outbreak was foremost oriented to two objectives: saving lives and limiting economic losses. However, the effectiveness and success factors of interventions were unknown ex-ante. This study aims to shed light on the drivers of countries' performances...

In a model on population and endogenous technological change, Kremer combines a short-run Malthusian scenario where income determines the population that can be sustained, with the Boserupian insight that greater population spurs technological change and can therefore lift a country out of its...

This study critically reviews quantitative methods that have been employed and evidence that has been gathered to assess the benefits of marriage and consequences of other family structures. The study begins by describing theoretical models of the determinants of different well-being outcomes...

Most labor scarce overseas countries moved decisively to restrict their immigration during the first third of the 20th century. This autarchic retreat from unrestricted and even publiclysubsidized immigration in the first global century before World War I to the quotas and bans introduced...

In a model on population and endogenous technological change, Kremer combines a short-run Malthusian scenario where income determines the population that can be sustained, with the Boserupian insight that greater population spurs technological change and can therefore lift a country out of its...

The Easterlin paradox" suggests that there is no link between a society's economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive...
