In the context of recent California drought years, we investigate empirically whether consumers are willing to pay for more efficient water usage in the production of four California agricultural products. We implement an internet survey choice experiment for avocados, almonds, lettuce, and...

We explore Tinbergen's fundamental insight that policymakers need at least as many policy instruments as targets. We extend this idea using a large natural field experiment in water resource management. We use social comparisons and loss-framed messages to help achieve two goals of our partner...

Despite increasing calls for reform many countries continue to provide subsidies for gasoline and diesel. This paper quantifies the external costs of global fuel subsidies using the latest available data and estimates from the World Bank and International Monetary Fund. Under preferred...

Most regulations designed to reduce environmental externalities impose costs on individuals and firms. An active body of research has explored how these costs are disproportionately born by different sectors of the economy and/or across different groups of individuals. However, much less is...

DuPont, one of the most respectable U.S. companies, caused environmental damage that ended up costing the company around a billion dollars. By using internal company documents disclosed in trials we rule out the possibilities that this bad outcome was due to ignorance, an unexpected realization,...

Recent empirical work in several economic fields, particularly environmental and energy economics, has adapted the regression discontinuity (RD) framework to applications where time is the running variable and treatment begins at a particular threshold in time. In this guide for practitioners,...

Though over 90 percent of benefits from environmental quality improvements are attributed to long-term exposure, nearly all quasi-experimental evidence on the effects of pollution on health exploits changes in short-term exposure. Quantifying long-run exposure impacts requires a lasting,...

Using a unique dataset linking preschool blood lead levels (BLLs), birth, school, and detention data for 120,000 children born 1990-2004 in Rhode Island, we estimate the impact of lead on behavior: school suspensions and juvenile detention. We develop two instrumental variables approaches to...

We collect extensive data on worldwide trade by transportation mode and use this to provide detailed comparisons of the greenhouse gas emissions associated with output versus international transportation of traded goods. International transport is responsible for 33 percent of world-wide...

Has the expansion in exports affected pollution and health outcomes across different prefectures in China in the two decades between 1990 and 2010? We exploit variation in the initial industrial composition to gauge the effect of export expansion due to the decline in tariffs faced by Chinese...
