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...

A large body of research documents that the 2010 dependent coverage mandate of the Affordable Care Act was responsible for significantly increasing health insurance coverage among young adults. No prior research has examined whether sexual minority young adults also benefitted from the dependent...

We examine the effects of state health insurance mandates requiring coverage of screening mammograms. We find robust evidence that mammography mandates significantly increased mammography screenings by 4.5-25 percent. Effects are larger for women with less than a high school degree in states...

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...

Twenty-one states and the District of Columbia require youths to wear helmets when riding a bicycle, and there has been a push to extend such laws to adults. We provide new evidence on helmet laws by studying Canada using difference-in-differences models and restricted area-identified public...

We study the direct and spillover effects of state requirements that middle school youths obtain a tetanus, diphtheria, and pertussis (Tdap) booster prior to middle school entry. These mandates increased vaccine take-up by 29 percent and reduced pertussis (whooping cough) incidence in the...

We provide the first analysis of the relationship between economic conditions and the use of illicit drugs other than marijuana. Drawing on US data from 2002-2013, we find mixed evidence with regard to the cyclicality of illicit drug use. However, there is strong evidence that economic downturns...

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 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...
