Public recognition is a frequent tool for motivating desirable behavior, yet its welfare effects are rarely measured. We develop a portable money-metric approach for measuring the direct welfare effects of shame and pride, which we deploy in a series of experiments on exercise and charitable...

Although fake online customer reviews have become prevalent on platforms such as Amazon, Google, and Facebook, little is known about how these reviews influence consumer behavior. This paper provides the first experimental estimates of the effects of fake reviews on individual demand and...

We develop novel estimates of peak and off-peak price elasticities for urban mass transit demand in San Francisco using a large natural experiment with 3.6 million trip sessions and a natural field experiment that both have exogenous price subsidies. We then estimate the welfare impacts for...

A growing body of empirical work shows that social recognition of individuals' behavior can meaningfully influence individuals' choices. This paper studies whether social recognition is a socially efficient lever for influencing individuals' choices. Because social recognition generates utility...

Economic theory suggests that energy subsidies can lead to excessive consumption and environmental degradation. However, the precise impact of energy subsidies is not well understood. We analyze a large energy subsidy: the California Alternate Rates for Energy (CARE). CARE provides a price...

Heat pumps have been proposed as the leading technology in the electrification of domestic heat and therefore could play a crucial part in the transition to low-carbon energy systems. However, there is very little causal evidence of the impact of heat pumps on energy demand and the impact of...

What are the most effective ways to address climate change? This paper extends and applies the marginal value of public funds (MVPF) framework to help answer this question. We examine 96 US environmental policy changes studied over the past 25 years. These policies span subsidies (wind,...
