The 1994 discovery of arsenic in groundwater in Bangladesh prompted a massive public health campaign that led 20% of the population to switch from backyard wells to less convenient drinking water sources that had a higher risk of fecal contamination. We find evidence of unintended health...

Healthy teeth are a vital and visible component of general well-being, but there is little systematic evidence to demonstrate their economic value. In this paper, we examine one element of that value, the effect of oral health on labor market outcomes, by exploiting variation in access to...

We examine the impact of piped water on the under-1 infant mortality rate (IMR) in Brazil using a novel econometric procedure for the estimation of quantile treatment effects with panel data. The provision of piped water in Brazil is highly correlated with other observable and unobservable...

Assessing the impact of lead exposure is difficult if individuals select on the basis of their characteristics into environments with different exposure levels. We address this issue with data from when the dangers of lead exposure were still largely unknown, using new evidence on intelligence...

In this paper we consider how the dental industry responded to the addition of fluoride to public drinking water. We take advantage of the staggered introduction of fluoridation throughout the country to analyze the changes in numbers of within-county dentists relative to physicians in the years...

This paper provides estimates of the effects of in utero exposure to contaminated drinking water on fetal health. We examine the universe of birth records and drinking water testing results for the state of New Jersey from 1997 to 2007. Our data enable us to compare outcomes across siblings who...

Previous research in the US has found negative health effects of contamination when it triggers regulatory violations. An important question is whether levels of contamination that do not trigger a health-based violation impact health. We study the impact of drinking water contamination in...

While shale gas development can result in rapid local economic development, negative externalities associated with the process may adversely affect the prices of nearby homes. We utilize a triple-difference estimator and exploit the public water service area boundary in Washington County,...

Historically, improvements in municipal water quality reduced mortality substantially in wealthy countries. However, water disinfection has not produced equivalent benefits in developing countries today. We investigate this puzzle by analyzing a large-scale municipal water disinfection program...

In this paper, we examine the impact of poor water quality on avoidance behavior by estimating the change in bottled water purchases in response to drinking water violations. Using data from a national grocery chain matched with water quality violations, we find an increase in bottled water...
