New technologies allow perfect detection of environmental violations at near-zero marginal cost, but take-up is low. We conducted a field experiment to evaluate enforcement of water conservation rules with smart meters in Fresno, CA. Households were randomly assigned combinations of enforcement...

The efficiency properties of price and non-price instruments for conservation in environmental policy are well understood. Yet, there is little evidence comparing the effectiveness of these instruments, especially when considering water resource management. We exploit a rich panel of residential...

Water suppliers are showing greater interest in using different mechanisms to promote conservation. One such mechanism is conducting home water audits, which involves assessing water use and providing tailored suggestions for conserving water for residential customers. Yet, very little is known...

Groundwater is a key resource for agricultural production globally. Increasingly rapid aquifer drawdowns--as well as the policies intended to increase their sustainability--increase costs to agricultural producers, with unknown consequences. This paper provides the first large-scale empirical...

This paper exploits the seasonal and annual changes in marginal prices for water to estimate the price elasticity of demand by residential households for water. It uses the changes in distributions of water using the census block group levels in response to changes in marginal prices of water...

We investigate the relationship between the extent of a city's subway network, its population and its spatial configuration. For the 632 largest cities in the world we construct panel data describing population, measures of centralization calculated from lights at night data, and the extent of...
