The public economic burden of shifting trends in population health remains uncertain. Sustained increases in obesity, diabetes, and other diseases could reduce life expectancy - with a concomitant decrease in the public-sector's annuity burden - but these savings may be offset by worsening...

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...

As policymakers consider expanding insurance coverage for HIV+ individuals, it is useful to ask if insurance has any affect on health outcomes; and, if so, whether public insurance is as efficacious as private insurance in preventing premature deaths among HIV+ patients. Using data from a...

A popular policy option for addressing the growth in weight has has been the imposition of a "fat tax" on selected foods that are deemed to promote obesity. Understanding the public economics of "fat taxes" requires an understanding of how or even whether individuals respond to changes in food...

The classic theory of moral hazard concerns the insurance of a single good and predicts that co-insurance is larger when the elasticity of demand is higher and when small risks are insured. We extend this analysis to the insurance of multiple goods; for example, the simultaneous insurance of...

Many companies have defined-contribution benefit plans requiring employees to pay the full cost (before taxes) of more generous health insurance choices. Research has shown that employee decisions are quite responsive to these arrangements. What is less clear is how the total compensation...

As health care costs continue to rise, medical expenses have become an increasingly important contributor to financial risk. Economic theory suggests that when background risk rises, individuals will reduce their exposure to other risks. This paper presents a test of this theory by examining the...

New medical technologies hold tremendous promise for improving population health, but they also raise concerns about exacerbating already large differences in health by socioeconomic status (SES). If effective treatments are more rapidly adopted by the better educated, SES health disparities may...

Nearly 30 percent of Americans age 65 and older supplement their Medicare health insurance through the Medigap private insurance market. We show that prices for Medigap policies vary widely, despite the fact that all plans are standardized, and even after controlling for firm heterogeneity....

Better-educated people are healthier, but the magnitude of the relationship between health and education varies substantially across groups and over time. We undertake a theoretical and empirical study of how health disparities by education vary over time and across the population, according to...
