Research has shown a strong negative correlation between birth order and cognitive test scores, IQ, and educational outcomes. We ask whether birth order differences in health are present at birth using matched administrative data for more than 1,000,000 children born in Denmark between 1981 and...

We analyze interaction effects of birth weight and the business cycle at birth on individual cardiovascular (CV) mortality later in life. In addition, we examine to what extent these long-run effects run by way of cognitive ability and education and to what extent those mitigate the long-run...

It is a well known fact that economic development and distance to the equator are positively correlated variables in the world today. It is perhaps less well known that as recently as 1500 C.E. it was the other way around. The present paper provides a theory of why the 'latitude gradient'...

This paper investigates the economic returns to parental health. To account for potential endogeneity between parental health and child outcomes, we leverage longitudinal microdata from Indonesia to estimate individual fixed effects models. Our results show that the economic returns to parental...

We explore the effects of a child labor regulation that changed the legal working age from 14 to 16 over the health of their offspring. We show that the reform was detrimental for the health of the son’s of affected parents at delivery. Yet, in the medium run, the effects of the reform are...

This paper studies the effects of day care exposure on behavioral disorders and mental and physical health at various ages during childhood. We draw on a unique set of merged population register data from Sweden over the period 1999-2008. This includes merged information at the individual level...

The paper develops a theoretical framework, and a diagrammatic apparatus, for explaining the supply of child labour. It examines the effect of credit, insurance, and poverty (defined as more than just low income). It also explains bonded child labour, a modern form of slavery closely associated...

This paper studies the effects of day care exposure on behavioral problems and mental health as well as on various aspects of physical health, at various ages during childhood. We draw on a unique set of comprehensive individual-level out-patient and inpatient health care register data from...

We analyze data from the Minnesota Twin Registry (MTR), combined with the Socioeconomic Survey of Twins (SST), and new mortality data, and contribute to two bodies of literature. First, we demonstrate a beneficial causal effect of education on health and longevity in contrast to other twin-based...

Over the past decades, the share of very young children in daycare has increased significantly in many OECD countries, including Germany. Despite the relevance of child health for child development and later life success, the effect of early daycare attendance on health has received little...
