This paper examines the effects of introducing compulsory attendance laws on the schooling of U.S. children for three overlapping time periods: 1880-1927, 1890-1927, and 1898-1927. The previous literature finds little effect of the laws, which is somewhat surprising given that the passage of...

This paper studies the immediate and long-run mortality effects of the first community-based health intervention in the world, which had a particular focus on controlling tuberculosis - the so-called Framingham Health and Tuberculosis Demonstration. Comparing death and TB-mortality rates between...

The paper reconsiders the nature of mining districts and property rights during the California gold rush. According to a widely accepted view advanced by Umbeck (1977, 1981), in the absence of effective legal authority, district codes established secure property rights in mining claims. Drawing...

Surface soil contamination has been long recognized as an important pathway of human lead exposure, and is now a worldwide health concern. This study estimates the causal effects of exposure to lead in topsoil on cognitive ability among 5-year-old children. We draw on individual level data from...

This paper constructs new estimates of the air pollution and greenhouse gas costs from long-distance movement of petroleum products by rail and pipelines. While crude oil transportation has generated intense policy debate about rail and pipeline spills and accidents, important externalities –...

We explore the rise and fall of pellagra, a disease caused by inadequate niacin consumption, in the American South, focusing on the first half of the twentieth century. We first consider the hypothesis that the South's monoculture in cotton undermined nutrition by displacing local food...

This paper draws on a new state-level panel dataset and a model of domestic Dutch disease to examine the short-run and long-run effects of oil & natural gas, coal, and agricultural land endowments on state economies during 1936-2015. Using a flexible shift-share estimation approach, where the...

Using U.S county level data on lead in air for 1978-1988 and lead in topsoil in the 2000s, this paper examines the impact of lead exposure on a critical human function with societal implications – fertility. To provide causal estimates of the effect of lead on fertility, we use two sets of...

Using U.S county level data on lead in air for 1978-1988, this paper provides the first causal evidence on the effects of airborne lead exposure on the general fertility rate and the completed fertility rate in the broad population. Instrumental variable estimates show the increase in completed...
