The effect of competition on the quality of health care remains a contested issue. Most empirical estimates rely on inference from non experimental data. In contrast, this paper exploits a pro-competitive policy reform to provide estimates of the impact of competition on hospital outcomes. The...

The impacts of choice in public services are controversial. We exploit a reform in the English National Health Service to assess the impact of relaxing constraints on patient choice. We estimate a demand model to evaluate whether increased choice increased demand elasticity faced by hospitals...

The literature on mergers between private hospitals suggests that such mergers often produce little benefit. Despite this, the UK government has pursued an active policy of hospital merger. These mergers are initiated by a regulator, acting on behalf of the public, and justified on the grounds...

The model developed in this paper is a model of internal non-price competition among members of a cooperative firm. Members take price arid income distribution method as given, but perceive a positive relationship between their own production of quality and the flow of consumers to them, when...

The goal of this paper is to identify key issues concerning the nature of competition in health care markets and its impacts on quality and social welfare and to identify pertinent findings from the theoretical and empirical literature on this topic. The theoretical literature in economics on...

What is the nature of the industrial organization of the market for physician services? Is the market 'competitive?' Are there pareto-relevant market failures, such that there is room for welfare improving policies? Economists have devoted a great deal of attention to this market, but it remains...

Recent work has shown that, in the presence of moral hazard, balanced budget Nash equilibria in groups are not pareto-optimal. This work shows that when agents misperceive the effects of their actions on the joint outcome, there exist a set of sharing rules which balance the budget and lead to a...

We examine HMO participation and enrollment in the Medicare risk market for the years 1990 to 1995. We develop a profit- maximization model of HMO behavior, which explicitly considers potential linkages between an HMO's production decision in the commercial enrollee market and its participation...

In this paper we review issues relating to antitrust and competition in health care markets. The paper begins with a brief review of antitrust legislation. We then discuss whether and how health care is different from other industries in ways that might affect the optimality of competition. The...

Despite the continuing US hospital merger wave, it remains unclear how mergers change, or fail to change, hospital behavior and performance. We open the "black box" of hospital practices through a mega-merger between two for-profit chains. Benchmarking the merger's effects against the acquirer's...
