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 test the effectiveness of an entertainment education TV series, MTV Shuga, aimed at providing information and changing attitudes and behaviors related to HIV/AIDS. Using a simple model we show that "edutainment" can work through an individual or a social channel. We conducted a randomized...

During health crises, like COVID-19, individuals are inundated with messages promoting health-preserving behavior. Does additional light-touch messaging by a credible individual change behavior? Do the features of the message matter? To answer this, we conducted a large-scale messaging campaign...

Sedentary lifestyles, obesity, and obesity-related chronic diseases have become increasingly common among U.S. adults, posing a major health policy challenge. While individuals may be interested in exercising more to reduce these health risks, they often have difficultly forming long-term...

Public technology assessments in general and Comparative Effectiveness Research (CER) in particular have been justified by offsetting benefits of improving patient health and reducing health care spending. However, little conceptual and empirical understanding exists concerning the quantitative...

In 1975, 50 year-old Americans could expect to live slightly longer than their European counterparts. By 2005, American life expectancy at that age has diverged substantially compared to Europe. We find that this growing longevity gap is primarily the symptom of real declines in the health of...

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...

We study spillover effects of the largest ever increase in Medicaid primary care reimbursement rates on behavioral health and healthcare outcomes; mental illness, substance use disorders, and tobacco product use. Much of the variation in Medicaid reimbursement rates we leverage is attributable...

This paper examines the impacts of the Affordable Care Act (ACA) - which substantially increased insurance coverage through regulations, mandates, subsidies, and Medicaid expansions - on behaviors related to future health risks after three years. Using data from the Behavioral Risk Factor...

Screening interventions can produce very different treatment outcomes, depending on the reasons why patients had been unscreened in the first place. Economists have paid scant attention to these complexities and their implications for evaluating screening programs. In this paper, we propose a...
