A puzzling feature of many medical innovations is that they simultaneously appear to reduce unit costs and increase total costs. We consider this phenomenon by examining the diffusion of percutaneous transluminal coronary angioplasty (PTCA) -- a treatment for coronary artery disease -- over the...

In this paper, we characterize the multi-faceted health of the elderly and understand how health along multiple dimensions has changed over time. Our data are from the Medicare Current Beneficiary Survey, 1991-2007. We show that 19 measures of health can be combined into three broad categories:...

The long-standing inverse relationship between education and mortality strengthened substantially later in the 20th century. This paper examines the reasons for this increase. We show that behavioral risk factors are not of primary importance. Smoking has declined more for the better educated,...

Prior studies suggest that, with elastically supplied inputs, free entry may lead to an inefficiently high number of firms in equilibrium. Under input scarcity, however, the welfare loss from free entry is reduced. Further, free entry may increase use of high-quality inputs, as oligopolistic...

Medical care is characterized by enormous inefficiency. Costs are higher and outcomes worse than almost all analyses of the industry suggest should occur. In other industries characterized by inefficiency, efficient firms expand to take over the market, or new firms enter to eliminate...

We develop a model of induced innovation where research effort is a function of the death rate, and thus the potential to reduce deaths in the population. We also consider potential social consequences that arise from this form of induced innovation based on differences in disease prevalence...

We analyze the incidence of public-employee health benefits. Because these benefits are negotiated through the political process, relevant labor market institutions deviate significantly from the competitive, private-sector benchmark. Empirically, we find that roughly 15 percent of the cost of...

Using Eurobarometer data, we document large variation across European countries in education gradients in income, self-reported health, life satisfaction, obesity, smoking and drinking. While this variation has been documented previously, the reasons why the effect of education on income, health...

A substantial literature has studied the influence of malpractice pressure on physician behavior. However, these studies generally focus on malpractice pressure stemming from state laws that govern liability exposure, which may be unknown or not salient to physicians. We test how physicians...

The introduction of Medicare in 1965 was the single largest change in health insurance coverage in U.S. history. Many economists and commentators have conjectured that the introduction of Medicare may have also been an important impetus for the development of new drugs that are now commonly used...
