Despite increasing calls for value-based payments, existing methodologies for determining physicians' "value added" to patient health outcomes have important limitations. We incorporate methods from the value added literature in education research into a health care setting to present the first...

Chay, Guryan and Mazumder (2009) found substantial racial convergence in AFQT and NAEP scores across cohorts born in the 1960's and early 1970's that was concentrated among blacks in the South. We demonstrated a close tracking between variation in the test score convergence across states and...

This paper estimates the effects of friends' health behaviors, smoking and drinking, on own health behaviors for adolescents while controlling for the effects of correlated unobservables between those friends. Specifically, the effect of friends' health behaviors is identified by comparing...

To American and European economists in 1945, the countries of Asia were unpromising candidates for high economic growth. In 1950 even the most prosperous of these countries had a per capita income less than 25 percent of that of the United States. Between the mid-1960s and the end of the...

While there is a well-established, large positive correlation between mental and physical health and education outcomes, establishing a causal link remains a substantial challenge. Building on findings from the biomedical literature, we exploit specific differences in the genetic code between...

The escalating rate of obesity in the US highlights the importance of understanding the causes for this rise. In this paper I employ the First, Second, and Third National Health and Nutrition Examination Surveys to estimate a structural model of the determinants of adult obesity. To control for...

Birth weight has emerged as the leading indicator of infant health and welfare and the central focus of infant health policy. This is because low birth weight (LBW) infants experience severe health and developmental difficulties that can impose enormous costs on society. But would the prevention...

We examine the effects of total suspended particulates (TSPs) air pollution on infant health using the air quality improvements induced by the 1970 Clean Air Act Amendments (CAAA). This legislation imposed strict regulations on industrial polluters in nonattainment' counties with TSPs...

Cost savings associated with increased gasoline prices and lower levels of urban sprawl have been cited in terms of personal savings, environmental awareness, reduced costs through lower travel times and congestion, and reduced income inequality. Cost savings in terms of improved health,...

Over the past three centuries there has been a rapid accumulation of physiological capital in OECD countries. Enhanced physiological capital is tied to long-term reduction in environmental hazards and to the conquest of chronic malnutrition. Data on heights and birth weights suggests that...
