In this paper, we examine the impact of the coal boom in the 1970s and the subsequent coal bust in the 1980s on local labor markets in Kentucky, Ohio, Pennsylvania, and West Virginia. We address two main questions in our analysis. How were non-mining sectors affected by the shocks to the mining sector? How did these effects differ between sectors producing(More)
In the Medicare program, increases in cost sharing by a supplemental insurer can exert financial externalities. We study a policy change that raised patient cost sharing for the supplemental insurer for retired public employees in California. We find that physician visits and prescription drug usage have elasticities that are similar to those of the RAND(More)
A series of influential papers by Christopher J. Ruhm (2000, 2003, 2005, 2008) documents that recessions are “good for your health”—or, more specifically, that state-level mortality rates are strongly procyclical. The magnitude of the correlation is economically meaningful: a typical estimate from the literature suggests that a 1 percentage point increase(More)
The quality of care received by Medicare beneficiaries varies across areas. We find that states with higher Medicare spending have lower-quality care. This negative relationship may be driven by the use of intensive, costly care that crowds out the use of more effective care. One mechanism for this trade-off may be the mix of the provider workforce: States(More)
Mounting malpractice liability costs might affect physician practice patterns in many ways, such as increasing the use of diagnostic procedures while reducing major surgeries. This paper quantifies the association between malpractice liability costs and the use of physician services in Medicare. We find that higher malpractice awards and premiums are(More)
A large literature in medicine documents variation across areas in the use of surgical treatments that is unrelated to outcomes. Observers of this phenomena have invoked "flat of the curve medicine" to explain these facts, and have advocated for reductions in spending in high-use areas. In contrast, we develop a simple Roy model of patient treatment choice(More)
We examine the relationship between large infrastructure spending, of the type implied by interstate highway construction, and the level of economic activity. By collecting historical data on interstate highway construction and economic activity in the United States at the county level we find that highways have a differential impact across industries:(More)
BACKGROUND Previous studies have documented racial disparities in treatment of acute myocardial infarction (AMI) among Medicare beneficiaries. However, the extent to which unobserved differences between hospitals explains some of these differences is unknown. OBJECTIVE The objective of this study was to determine whether the observed racial treatment(More)
There is enormous geographic variation in the use of cesarean delivery: For births over 2,500 grams, adjusted cesarean rates vary fourfold between low- and high-use areas. Even for births under 2,500 grams, high-use counties have rates that are double those of low-use ones. Higher cesarean rates are only partially explained by patient characteristics but(More)
Measuring consumer responsiveness to medical care prices is a central issue in health economics and a key ingredient in the optimal design and regulation of health insurance markets. We leverage a natural experiment at a large self-insured firm that required all of its employees to switch from an insurance plan that provided free health care to a(More)
