Between 1960 and 1997, life expectancy at birth of Americans increased approximately 10% - from 69.7 to 76.5 years - and it has been estimated that the value of life extension during this period nearly equaled the gains in tangible consumption. We investigate whether an aggregate health...

The social value of an innovation is comprised of the value to consumers and the value to innovators. We estimate that for the HIV/AIDS therapies that entered the market from the late 1980's onwards, innovators appropriated only 5% of the social surplus arising from these new technologies....

Inefficiency in the U.S. health care system has often been characterized as quot;flat of the curvequot; spending providing little or no incremental value. In this paper, we draw on macroeconomic models of diffusion and productivity to better explain the empirical patterns of outcome improvements...

I study the channels through which health insurance influences medical innovation. Following Medicare and Medicaid's passage, I find that U.S.-based medical-equipment patenting rose by 40 to 50 percent relative to both other U.S. patenting and foreign medical-equipment patenting. Within the...

Cost-effectiveness analysis (CEA), despite its known limitations, continues as the primary method used for health technology assessment (HTA) both officially (UK, Australia and Canada) and less formally elsewhere. Standard CEA models compare incremental cost increases to incremental average...

Cost-effectiveness analysis (CEA) remains the de-facto method of choice to evaluate and compare medical interventions. Standard approaches to CEA use the average (mean) outcomes from clinical effectiveness studies such as randomized controlled trials. This paper generalizes standard methods to...

Increasing managed care activity could influence the adoption and diffusion of new medical technologies. This paper empirically examines the relationship between HMO market share and the diffusion of magnetic resonance imaging (MRI) equipment. Across markets, increases in HMO market share are...

Many questions about technology growth and development in health care call for a broad-based characterization of technology availability. In this paper, we explore the possibility of producing aggregated estimates of technology availability by constructing an index of technology availability in...
