Poor water quality and sanitation are leading causes of mortality and disease in developing countries. However, interventions providing toilets in rural areas have not substantially improved health, likely because of incomplete coverage and low usage. This paper estimates the impact of an...

Cities generate negative, as well as positive, externalities; addressing those externalities requires both infrastructure and institutions. Providing clean water and removing refuse requires water and sewer pipes, but the urban poor are often unwilling to pay for the costs of that piping....

We study the extent to which collusion can explain the under-provision of clean sanitation technologies in developing countries. Using desludging services in Dakar as a case-study, we document that prices are 66% higher in areas where prices are likely coordinated by a large trade association,...

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...

Fresh water supplies increasingly are under stress in many parts of the world due to rising populations, higher per capita incomes and corresponding consumption, greater environmental concerns, and the effects of climate change. Water rights and markets are part of the institutional menus for...

The construction of municipal water systems was a major event in the history of American cities -- bringing relief from disease, providing resources to combat fires, attracting business investment, and promoting development generally. Although the first large-scale municipal water system in the...

Providing clean water requires maintenance, as well as the initial connections that are typically measured. Frequently, the water supply fails in the developing world, especially when users don't pay the marginal cost of water. This paper uses the timing of frequent, unexpected water service...

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...
