Applying conventional horizontal merger enforcement rules to mergers of nonprofit hospitals is controversial. Critics contend that the different objective function of not-for-profits entities should mitigate, and possibly eliminate, competitive concerns about mergers involving nonprofit hospitals. We provide evidence relevant to this debate by analyzing ex post a horizontal merger in a concentrated hospital market. Here, the transaction reduced the number of competitors (both nonprofit) in the alleged relevant market from three to two. We find that the transaction resulted in significant price increases; we reject the hypothesis that these price increases reflect higher post-merger quality. This study should help policymakers assess the validity of current merger enforcement rules, especially as they apply to not-for-profit enterprises.

The health care industry continues to undergo unprecedented consolidation. Health care providers and payors alike have pursued a wide variety of integrative strategies to achieve efficiencies or other business advantages. The Health Care Mergers and Acquisitions Handbook is designed to educate the practitioner about the antitrust analysis of mergers and acquisitions within the health care industry. Over the past two decades there has been an extraordinary amount of litigation related to challenges of hospital mergers. Each chapter identifies and analyzes important antitrust issues governing such consolidations. Accordingly, the first several chapters are devoted to a detailed treatment of substantive issues peculiar to such mergers: an introduction to hospital merger litigation, describing trends in litigation and the way in which such mergers are analyzed; issues unique to market definition, including product market definition and geographic market definition; the competitive effects of hospital mergers, assessing the evidence necessary to establish a prima facie case in a merger challenge and the rebuttal arguments offered by merging parties; a unique rebuttal argument offered by merging hospitals that is treated separately due to its prominent role in hospital merger litigation - the role and significance of efficiencies in determining the competitive merits of such mergers; the potential applicability of the state action doctrine to hospital mergers. In addition to a substantive treatment of hospital mergers, the Handbook also addresses; combinations of health care management organizations (HMOs) and physician practice groups; the analysis used by the enforcement agencies when reviewing mergers of HMOs; antitrust issues posed by physician practice consolidations. The appendix contains a chart summarizing litigated hospital mergers.--

Following a string of government losses in cases challenging hospital mergers in federal court, the Federal Trade Commission and the Department of Justice issued their report on competition in health care seeking to set the record straight on a number of issues that underlie the judiciary's resolution of these cases. One such issue is the import of nonprofit status for applying antitrust law. This essay describes antitrust's role in addressing the consolidation in the hospital sector and the subtle influence that the social function of the nonprofit hospital has had in merger litigation. Noting that the political and social context in which these institutions operate is never far from the surface, it takes issue with the proposal to cabin merger doctrine so as to deny the significance of nonprofit status in merger analysis. Given the dynamic change in the regulatory climate and heterogeneity of local health care markets, it advises courts not to accept the FTC's preemptive standard regarding the significance of hospitals' nonprofit status and keep open the possibility of fashioning new presumptive rules tailored to more complete economic accounts of nonprofit firm behavior.
