This book covers the consolidation and merger of corporations and corporate divestiture in the United States.

Consolidation via merger both from hospital-to-hospital mergers and from hospital acquisitions of physician groups is changing the competitive landscape of the provision of health care delivery in the United States. This Article undertakes a legal and economic examination of a recent Ninth Circuit case examining the hospital acquisition of a physician group. This Article explores the Saint Alphonsus Medical Center-Nampa Inc. v. St. Luke's Health System, Ltd. (St. Luke's) decision -- proposing a type of analysis that the district court and Ninth Circuit should have undertaken and that we hope future courts undertake when analyzing mergers in the health care sector. First, the Article addresses the question of how best to frame the acquisition of a physician group by a hospital -- is the merger horizontal, vertical, or potentially both? In undertaking this analysis the Article examines the broader issue of the treatment of Accountable Care Organizations (ACOs) in antitrust law. ACOs are short of full integration and as such, a potential contractual alternative for hospitals and physician groups to an acquisition. A hospital acquisition of a physician practice also has implications for how to view competitive effects in the context of ACOs. Indeed, in St. Luke's the Ninth Circuit suggests that integration short of full merger was a possible alternative. Second, the Article examines the justification for integration as a way to address countervailing power in health care, the reduction of transaction costs, and potential cost and quality efficiencies. Third, the Article applies the economics of these issues to merger case law generally and specifically to the St. Luke's decision. Ultimately, the Article finds the economic analysis of the Ninth Circuit lacking. Finally, the Article offers policy implications of the decision and concludes with some suggestions to improve health care antitrust analysis in practice for litigated cases to make such analysis better follow economic principles.

Mergers And Efficiency: Changes Across Time focuses on one aspect of the corporate finance revolution that restructured Corporate America and led to the longest expansion in U.S. history - changes in rates of merger efficiency. Demystifying this most controversial and dynamic period of U.S. economic history is key to understanding the business, financial and economic innovations that defined the last two decades of the 20th century. In addition, it is important to create a careful empirical understanding of the conditions under which merger activity increased or decreased firm efficiency, industrial productivity, and overall improvements in aggregate output and economic performance.

Mergers and Productivity offers probing analyses of high-profile mergers in a variety of industries. Focusing on specific acquisitions, it illustrates the remarkable range of contingencies involved in any merger attempt. The authors clearly establish each merger's presumed objectives and the potential costs and benefits of the acquisition, and place it within the context of the broader industry. Striking conclusions that emerge from these case studies are that merger and acquisition activities were associated with technological or regulatory shocks, and that a merger's success or failure was dependent upon the acquirer's thorough understanding of the target, its corporate culture, and its workforce and wage structures prior to acquisition. Sifting through a wealth of carefully gathered evidence, these papers capture the richness, the complexity, and the economic intangibles inherent in contemporary merger activity in a way that large-scale studies of mergers cannot.
