This paper examines the pathways by which individuals transition from healthy to disabled. Because of the high prevalence and costs associated with disability, understanding these pathways is critical to developing interventions to prevent or minimize disability. We compare two estimates of...

There is little empirical evidence to explain why disability declined among the elderly over the past 20 years. In this paper, we explore the role of improved medical care for cardiovascular disease on health status improvements over time. We show that the incidence of cardiovascular disease...

There is a pronounced gradient in disability across socioeconomic groups, with better educated and higher income groups reporting substantially less disability. In this paper, we consider why that is the case, focusing on impairments in basic physical and cognitive aspects of living for the...

During the past two decades, several public and private organizations have initiated programs to report publicly on the quality of medical care provided by specific hospitals and physicians. These programs have sparked broad debate among economists and policy makers concerning whether, and to...

Understanding how healthy lifespans are changing is essential for public policy. This paper explores changes in healthy lifespan in the U.S. over time and considers reasons for the changes. We reach three fundamental conclusions. First, we show that healthy life increased measurably in the US...

The question of whether morbidity is being compressed into the period just before death has been at the center of health debates in the United States for some time. Compression of morbidity would lead to longer life but less rapid medical spending increases than if life extension were...

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:...

Variation in HCC margins does not predict differences between an HCC's share of MA and TM enrollees, although one cannot a priori sign a relationship between margin and service-level selection. Margins are negatively associated with the importance of post-acute care in the HCC. Margins among...

US healthcare is undergoing a period of substantial change, with many hospitals vertically integrating with physician practices. Such integration could improve quality by promoting care coordination, but could also worsen it by impacting care delivery. Evidence on how physicians alter their...

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...
