Indoor tanning beds (ITBs) emit UV light at high intensity and have been classified as carcinogenic to humans by the World Health Organization since 2009. We are the first to study the role of state laws prohibiting youths from indoor tanning using a difference-in-differences research design. We...

We provide novel evidence on the role of social comparisons in shaping adolescent body misperception. Using an instrumental variables approach leveraging variation in relative age generated by school entry cutoff months and data from the Health Behaviour in School-Aged Children study, we show...

We provide novel evidence on the role of negative social comparisons in population health behaviors by exploiting variation in Miss America and Miss USA beauty pageant winners. We show that there was more front-page newspaper coverage and more pageant-related internet search behavior following a...

Using a US nationally representative sample and a double list experiment designed to elicit views free from social desirability bias, we find that anti-transgender labor market attitudes are significantly underreported. After correcting for this concealment, we report that 73 percent of people...

We provide the first evidence on transgender earnings in the US using administrative data on over 55,000 individuals who changed their gender marker with the Social Security Administration and had gender-congruent first name changes on tax records. We validate and describe this sample which...

Over 20 states have adopted laws requiring youths to wear a helmet when riding a bicycle. We confirm previous research indicating that these laws reduced fatalities and increased helmet use, but we also show that the laws significantly reduced youth bicycling. We find this result in standard...

We provide the first comprehensive assessment of the effects of mandatory seatbelt laws on self-reported seatbelt use, highway fatalities, and crash-related injuries among high school age youths using data from the Centers for Disease Control's (CDC) national, state, and local Youth Risk...

Recent large-scale randomized experiments find that helping people form implementation intentions by asking when and where they plan to act increases one-time actions, such as vaccinations, preventative screenings and voting. We investigate the effect of a simple scalable planning intervention...

The use of incentives to encourage healthy behaviors is increasingly widespread, but we have little evidence about how best to structure these programs. We explore how different incentive designs affect behavior on the extensive and intensive margins through an experiment offering incentives to...

Financial incentives have been shown to have strong positive short-run effects for problematic health behaviors, but the effects often disappear once incentive programs end. This paper analyzes the results of a large-scale workplace field experiment to examine whether self-funded commitment...
