Health care providers may vertically integrate not only to facilitate coordination of care, but also for strategic reasons that may not be in patients' best interests. Optimal Medicare reimbursement policy depends upon the extent to which each of these explanations is correct. To investigate, we...

This paper examines the efficiency and equity implications of alternative health care system financing strategies. Using data across the OECD, I find that almost all financing choices are compatible with efficiency in the delivery of health care, and that there has been no consistent and...

This article describes the anatomy of health insurance. It begins by considering the optimal design of health insurance policies. Such policies must make tradeoffs appropriately between risk sharing on the one hand and agency problems such as moral hazard (the incentive of people to seek more...

This paper is concerned with the economics of mental health. We argue that mental health economics is like health economics only more so: uncertainty and variation in treatments are greater; the assumption of patient self-interested behavior is more dubious; response to financial incentives such...

The main goal of this paper is to put forward a methodology for the measurement of product innovations using a value metric, i.e., equating the "magnitude" of innovations with the welfare gains that they generate. This research design is applied to the case of Computed Tomography (CT) Scanners,...

We develop an economic framework for valuing improvements to health and life expectancy, based on individuals' willingness to pay. We then apply the framework to past and prospective reductions in mortality risks, both overall and for specific life-threatening diseases. We calculate (i) the...

In health economics applications involving outcomes (y) and covariates (x), it is often the case that the central inferential problems of interest involve E[y|x] and its associated partial effects or elasticities. Many such outcomes have two fundamental statistical properties: yò0; and the...

This paper provides a theoretical and empirical investigation of the positive complementarities between disease-specific policies introduced by competing risks of mortality. The incentive to invest in prevention against one cause of death depends positively on the level of survival from other...

In this survey of recent research in health economics, I concentrate on studies that have appeared since 1971 or are in progress. The survey reflects in part my own research interests and biases and is not meant to be comprehensive. Four topics are covered: (1) demand for adults' health and...
