Electric vehicles are declining in cost so rapidly that they may claim a large share of the vehicle market by 2030. This paper examines a set of practical regulatory design considerations for fuel-economy standards or greenhouse gas standards in the context of highly uncertain electric vehicle...

What do we know about the size of the rebound effect? Should we believe claims that energy efficiency improvements lead to an increase in energy use? This paper clarifies what the rebound effect is, and provides a guide for economists and policymakers interested in its magnitude. We describe how...

This study examines the uneven effects of air pollution from maritime ports on physical and mental health across racial groups. We exploit quasi-random variation in vessels in port from weather events far out in the ocean to estimate how port traffic influences air pollution and human health. We...

Will a carbon tax improve the welfare consequences of policies to promote electric vehicles? This paper examines when a complementarity could exist between carbon pricing and high electric vehicle adoption. We analyze electricity generation in recent years to show that in several regions, carbon...

Pricing greenhouse gases is widely understood as the most efficient approach for mitigating climate change, yet distributional effects hamper political acceptance. These distributional effects are especially important in transport, the fastest growing sector for greenhouse gas emissions. Using...
