This paper estimates the effect of early lead exposure on academic achievement and adult earnings. We analyze longitudinal information from individuals attending primary and secondary schools in the city of Arica (in northern Chile). Between 1984 and 1989, Arica received more than 20,000 tons of...

This paper examines the influence of health conditions on academic performance during adolescence. To account for the endogeneity of health outcomes and their interactions with risky behaviors we exploit natural variation within a set of genetic markers across individuals. We present strong...

An open question in the literature is whether families compensate or reinforce the impact of child health shocks. Discussions usually focus on one dimension of child investment. This paper examines multiple dimensions using household survey data on Chinese child twins whose average age is 11. We...

This paper investigates the role of pain in determining self-reported work disability in the US, the UK and The Netherlands. Even if identical questions are asked, cross-country differences in reported work disability remain substantial. In the US and the Netherlands, respondent evaluations of...

Unlike most countries, Korea did not implement a lockdown in its battle against COVID-19, instead successfully relying on testing and contact tracing. Only one region, Daegu-Gyeongbuk (DG), had a significant number of infections, traced to a religious sect. This allows us to estimate the causal...

A large literature has documented links between harmful early life exposures and later life health and socioeconomic deficits. These studies, however, are typically unable to examine the possibility that these shocks are transmitted to the next generation. Our study traces the impacts of in...

Almond (2006) argues that in utero exposure to the 1918 influenza pandemic lowered socioeconomic status in adulthood, whereas Brown & Thomas (2018) find that the effect disappears after controlling for parental characteristics of the 1919 birth cohort. We link microdata from the 1920 and 1930...

We leverage a natural experiment, where a large national automotive racing organization switched from leaded to unleaded fuel, to study how ambient lead exposure and nutrition impact learning in elementary school. This provides quasi-experimental evidence linking measured quantities of lead...
