The Millennium Development Goals call for reducing by half the proportion of people without sustainable access to safe drinking water. This goal was adopted in large part because clean water was seen as critical to fighting diarrheal disease, which kills 2 million children annually. There is...

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...

We estimate the impact of piped water and sewers on property values in mid-19th century Chicago. The cost of sewer construction depends sensitively on imperceptible variation in grade, and such variations in grade delay water and sewer service to part of the city. This delay provides...

The Clean Water Act (CWA) significantly improved surface water quality, but at a cost exceeding the estimated benefits. We quantify the effect of the CWA on a direct measure of health and incorporate health benefits into a cost-benefit analysis. Using a difference-in-differences framework, we...

Agricultural producers make investment decisions based on beliefs about future returns. This article investigates how changes in beliefs about input availability affects the adoption of conservation practices. We develop a theoretical model to examine how a producer's beliefs about water...

U.S. cities invested heavily in water and sewer infrastructure throughout the late 19th and early 20th centuries. These investments improved public health and quality of life by helping U.S. cities control typhoid fever and other waterborne diseases. We show that segregated cities invested in...

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...

Behavioral constraints may explain part of low demand for preventive health products. We test the effects of two light-touch psychological interventions on water chlorination and related health and economic outcomes using a randomized controlled trial among 3750 women in rural Kenya. One...

In the half century since the founding of the U.S. Environmental Protection Agency, public and private U.S. sources have spent nearly $5 trillion ($2017) to provide clean rivers, lakes, and drinking water, or annual spending of 0.8 percent of U.S. GDP in most years. Yet over half of rivers and...

Property rights are widely prescribed for addressing overextraction of common pool resources, yet causal evidence of their effectiveness remains elusive. We develop a model of dynamic groundwater extraction to demonstrate how a spatial regression discontinuity design exploiting a...
