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...

Water suppliers are showing greater interest in using different mechanisms to promote conservation. One such mechanism is conducting home water audits, which involves assessing water use and providing tailored suggestions for conserving water for residential customers. Yet, very little is known...

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...

Increasing evidence indicates the importance of management in determining firms' productivity. Yet, causal evidence regarding the effectiveness of management practices is scarce, especially for high-skilled workers in the developed world. In an eight-month field experiment measuring the...

We study a large-scale (n=50,000) natural field experiment implemented by the U.S. Social Security Administration that was aimed at increasing the timely and accurate self-reporting of wages by Supplemental Security Income (SSI) recipients. Sending a letter reminding SSI recipients of their wage...

Little is known about individual beliefs concerning the Coronavirus Disease 2019 (COVID-19). Still less is known about how these beliefs influence the spread of the virus by determining social distancing behaviors. To shed light on these questions, we conduct an online experiment (n = 3,610)...

The value of time determines relative prices of goods and services, investments, productivity, economic growth, and measurements of income inequality. Economists in the 1960s began to focus on the value of non-work time, pioneering a deep literature exploring the optimal allocation and value of...

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...

Framing remains one of the pillars of behavioral economics. While framing effects have been found to be quite important in the lab, what is less clear is how well evidence drawn from naturally-occurring settings conforms to received laboratory insights. We use debt obligation to the UK...

Across many sectors, research has established that management explains a notable portion of productivity differences across organizations. A remaining question, however, is whether it is managers themselves or firm-wide management practices that matter. We shed light on this question by...
