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 paper presents experimental evidence that information feedback dramatically increases the price elasticity of demand in a setting where signals about quantity consumed are traditionally coarse and infrequent. In a randomized controlled trial, residential electricity customers are exposed to...

Imperfect information about product attributes inhibits efficiency in many choice settings, but can be overcome by providing simple, low-cost information. We use a randomized control trial to test the effect of high-frequency information about residential electricity usage on the price...

We provide the first at-scale estimate of electric vehicle (EV) home charging. Previous estimates are either based on surveys that reach conflicting conclusions, or are extrapolated from a small, unrepresentative sample of households with dedicated EV meters. We combine billions of hourly...
