Over 2 billion people lack clean drinking water. Existing solutions face high costs (piped water) or low demand (point-of-use chlorine). Using a 60,000 household cluster-randomized experiment we test an increasingly popular alternative: decentralized treatment and home delivery of clean water to...

Using data from an 18-month randomized trial, we estimate large and sustained impacts on water purification and child health of a program providing monthly coupons for free water treatment solution (diluted chlorine) to households with young children. The program is more effective and much more...

The recent drinking water crisis in Newark, New Jersey's largest city, has renewed concerns about the lead-in-water crisis becoming a persistent and widespread problem owing to the nation's aging infrastructure. We exploit a unique natural experiment in Newark, which exogenously exposed some...

Urban water conservation is typically achieved through prescriptive regulations, including the rationing of water for particular uses and requirements for the installation of particular technologies. A significant shift has occurred in pollution control regulations toward market-based policies...

Localities in developed countries often restrict construction and population growth through regulations governing land usage, lot sizes, building heights, and frontage requirements. In developing countries, such policies are less effective because of the existence of unregulated, informal...

We estimate the price elasticity of water demand with household-level data, structurally modeling the piecewise-linear budget constraints imposed by increasing-block pricing. We develop a mathematical expression for the unconditional price elasticity of demand under increasing-block prices and...

Rather than allowing water prices to reflect scarcity rents during periods of drought-induced excess demand, policy makers have mandated command-and-control approaches, like the curtailment of certain uses, primarily outdoor watering. Using unique panel data on residential end-uses of water, we...
