Evaluations of changes to the Medicaid program have focused on increases in the generosity of income cutoffs for Medicaid eligibility. Previous research shows that despite dramatic increases in the number of births paid for by the Medicaid program, women often enroll in Medicaid at the point of...

Decades of evidence reveal a complicated relationship between mammograms and mortality. Mammograms may detect deadly cancers early, but they may also lead to the diagnosis and potentially fatal treatment of cancers that would never progress to cause symptoms. I provide a brief history of the...

Using randomized methodologies, we study a common community HIV/AIDS program that seeks to promote HIV testing by improving knowledge and reducing stigmatizing attitudes. Contrary to expectations, the program has a substantial negative effect on HIV testing rates. We provide evidence of likely...

We study whether vouchers with and without value information encourage completion of already free follow-up appointments in a low-income minority population in Baltimore City referred for possible eye disease. Between May 2017 and September 2018, 821 individuals referred for free follow-up from...

We study impacts of a cash transfer program with no means-test and no work restrictions: the US Department of Veteran Affairs (VA) Disability Compensation program. Our empirical strategy leverages quasi-random assignment of veterans claiming mental disorder disability to examiners who vary in...

In the past few decades, some measures of population risk have improved, while others have deteriorated. Understanding the health of the population requires integrating these different trends. We compare the risk factor profile of the population in the early 1970s with that of the population in...

High-value preventive care is often underutilized. We study persuasion regarding the medical benefits of influenza vaccination by experimentally varying race concordance between sender and receiver, and, among Black respondents, a discordant sender's acknowledgement of historical injustice and...

Adverse behavioral risk factors contribute to a large share of deaths. We examine the effects on life expectancy (LE) and quality-adjusted life expectancy (QALE) of changes in six major behavioral risk factors over the 1960-2010 period: smoking, obesity, heavy alcohol use, and unsafe use of...

There is growing evidence on the importance of sleep for productivity, but little is known about the impact of interventions targeting sleep. In a field experiment among U.S. university students, we show that incentives for sleep increase both sleep and academic performance. Motivated by...

We project the effects of declining smoking and increasing obesity on mortality in the United States over the period 2010-2040. Data on cohort behavioral histories are integrated into these projections. Future distributions of body mass indices are projected using transition matrices applied to...
