The paper outlines various measures of profitability and considers what role they can play in competition law. We argue that profitability measures can provide a good answer to the wrong question and a much less good answer to the question we really want to answer. Using appropriate definitions...

Provider competition is a currently popular healthcare reform model. A necessary condition for greater competition to improve quality is that providers will face higher demand if they improve their quality. We test this crucial assumption in an important part of the health care market using data...

In this paper we focus on the implications of consumer heterogeneity for whether competition will improve outcomes in health care markets. We show that competition generally favours the majority group as higher quality for the majority is an effective way to increase the quality signal and...

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...

Payer-driven competition has been widely advocated as a means of increasing efficiency in health care markets. The 1990s reforms to the UK health service followed this path. We examine whether competition led to better outcomes for patients, as measured by death rates after treatment following...

In this paper we examine the causal impact of competition on management quality. We analyze the hospital sector where geographic proximity is a key determinant of competition, and English public hospitals where political competition can be used to construct instrumental variables for market...

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 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...
