We analyze exclusive contracts between health care providers and insurers in a model where some consumers choose to stay uninsured. In case of a monopoly insurer, exclusion of a provider changes the distribution of consumers who choose not to insure. Although the foreclosed care provider remains...

We provide a modeling framework to think about selective contracting in the health care sector. Two health care providers differ in quality and costs. When buying health insurance, consumers observe neither provider quality nor costs. We derive an equilibrium where health insurers signal...

This paper compares the welfare effects of three ways in which health care can be organized: no competition (NC), competition for the market (CfM) and competition on the market (CoM) where the payer offers the optimal contract to providers in each case. We argue that each of these can be optimal...

We present a model of optimal contracting between a purchaser and a provider of health services when quality has two dimensions. We assume that one dimension of quality is verifiable (dimension 1) and one dimension is not verifiable (dimension 2). We show that the power of the incentive scheme...

The determinants of the dramatically rising expenditures on health care in general, and on hospital care in particular, have been of prior concern to policy and to research. Using a rich panel data set this paper contributes to this literature by investigating factors determining the demand for...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities), using a Hotelling framework, in the presence of sluggish demand. We take a differential game approach, and derive the open-loop solution (providers commit to an...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities) taking a differential game approach, in which quality is a stock variable. Using a Hotelling framework, we derive the open-loop solution (providers commit to an...

Extending choice in health care is currently popular amongst English, and other, politicians. Those promoting choice make an appeal to a simple economic argument. Competitive pressure helps make private firms more efficient and consumer choice acts as a major driver for efficiency. Giving...

The Paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

We develop a model of waiting lists for public hospitals when physicians deliver both private and public treatment. Public treatment is free but rationed, i.e., only cases meeting some medical criteria are admitted for treatment. Private treatment has no waiting time but entails payment of a...
