There is an active debate about how to regulate electronic cigarettes, due to uncertainty about their health effects and whether they are primarily a quit aid or a gateway drug for combustible cigarettes. We model optimal e-cigarette regulation and estimate key parameters. Using tax changes and...

Governments often provide inconsistent guidance to the public. Does inconsistency affect how much people believe the latest recommendations? Using an incentivized online experiment with 1,900 US respondents in early April 2020, we present all participants with the latest official projection...

We study the U.S. rollout of eligibility expansions in the Supplemental Nutrition Assistance Program. Using administrative data from the U.S. Department of Agriculture, we show that expanding eligibility raises enrollment among the inframarginal (always-eligible) population. We use an online...

Transfer receipt is voluntary and costly, generating “self-targeting” through selective take-up among the eligible. How does self-targeting select on need, and what are its policy implications? We show self-targeting is advantageous in eight U.S. transfers: On average, recipients have lower...

This review paper provides an overview of the application of behavioral public economics to energy efficiency. I document policymakers' arguments for "paternalistic" energy efficiency policies, formalize with a simple model of misoptimizing consumers, review and critique empirical evidence, and...

"Site selection bias" can occur when the probability that a program is adopted or evaluated is correlated with its impacts. I test for site selection bias in the context of the Opower energy conservation programs, using 111 randomized control trials involving 8.6 million households across the...

Most US consumers are charged a near-constant retail price for electricity, despite substantial hourly variation in the wholesale market price. The Smart Grid is a set of emerging technologies that, among other effects, will facilitate "real-time pricing" for electricity and increase price...
