Coal heating in residential homes is an important source of indoor air pollution, leading to detrimental health effects. We conduct a randomized field experiment in northern China using three types of SMS campaigns targeting three potential biases that may hinder the adoption of electric...

After highly publicized lawsuits against McDonald's in 2002, 26 states adopted Commonsense Consumption Acts (CCAs) - aka 'Cheeseburger Bills' - that greatly limit fast food companies' liability for weight-related harms. We provide the first evidence of the effects of CCAs using plausibly...

We argue that in pharmaceutical markets, variation in the arrival time of consumer heterogeneity creates differences between a producer's ability to extract consumer surplus with preventives and treatments, potentially distorting R&D decisions. If consumers vary only in disease risk, revenue...

We study the impact of mandatory calorie posting on consumers' purchase decisions, using detailed data from Starbucks. We find that average calories per transaction falls by 6%. The effect is almost entirely related to changes in consumers' food choices--there is almost no change in purchases of...

This paper estimates the impact on consumer behavior of a firm's voluntary disclosure of information. Specifically, we study the impact of Starbucks' disclosure of calorie information on its menu boards in June 2013. Using data on over 250,000 consumers' visits to specific restaurant chains, we...

Media outlets often present diverging, even conflicting, perspectives on reality -- not only informing, but potentially misinforming audiences. We study the extent to which misinformation broadcast on mass media at the early stages of the coronavirus pandemic influenced health outcomes. We first...

The 2010 Patient Protection and Affordable Care Act (ACA) introduced a mandate requiring chain restaurants to post calorie counts on menus and menu boards. This paper investigates whether and why calorie posting laws work. To do so, we develop a model of calories consumed that highlights two...

Smoking is the leading preventable cause of death in the U.S. Because e-cigarettes do not involve the combustion of tobacco, vaping offers the potential to prevent most of the health consequences of smoking. We study the impact of an information shock created by an outbreak of lung injuries...

Genetic factors play a major role in the development of Alzheimer's disease and related dementias (ADRD). Observable genetic factors could impact household planning and medical care if they contain actionable information, meaning that they i) are associated with significant harms, ii) reflect...

Many environmental hazards produce health effects that take years to arise, but quasi-experimental studies typically measure outcomes and treatment over short time periods. We develop a new approach to overcome this challenge and use it to gauge the effect of exposure to air pollution on US life...
