This is an important and timely contribution from a prominent antitrust economist and policy advisor. It has been many decades since questions about antitrust enforcement have been so prominent in political, economic, and scholarly debate. Mergers in countless industries, rising concentration throughout the economy, and the dominance of tech giants have brought renewed attention to the role and the responsibility of antitrust policy.

A comprehensive analysis of merger outcomes based on all empirical studies, with an assessment of the effectiveness of antitrust policy toward mergers. In recent decades, antitrust investigations and cases targeting mergers—including those involving Google, Ticketmaster, and much of the domestic airline industry—have reshaped industries and changed business practices profoundly. And yet there has been a relative dearth of detailed evaluations of the effects of mergers and the effectiveness of merger policy. In this book, John Kwoka, a noted authority on industrial organization, examines all reliable empirical studies of the effect of specific mergers and develops entirely new information about the policies and remedies of antitrust agencies regarding these mergers. Combined with data on outcomes, this policy information enables analysis of, and creates new insights into, mergers, merger policies, and the effectiveness of remedies in preventing anticompetitive outcomes. After an overview of mergers, merger policy, and a common approach to merger analysis, Kwoka offers a detailed analysis of the studied mergers, relevant policies, and chosen remedies. Kwoka finds, first and foremost, that most of the studied mergers resulted in competitive harm, usually in the form of higher product prices but also with respect to various non-price outcomes. Other important findings include the fact that joint ventures and code sharing arrangements do not result in such harm and that policies intended to remedy mergers—especially conduct remedies—are not generally effective in restraining price increases. The book's uniquely comprehensive analysis advances our understanding of merger decisions and policies, suggests policy improvements for competition agencies and remedies, and points the way to future research.

GIULIANO MUSSATI Why do mergers occur, which are their effects on social welfare and which is the best economic policy toward them? These three questions have been puzzling industrial economists since the end of the last century when the first great merger wave has come about in the US. They have returned at the centre of the stage of the theoretical and empirical economic research during the last decade when merger and acquisition activity became one of the most evident firms' activities in all industrialised countries, being fostered by some general and country specific facts. These facts have been identified in the appearance of new financial instruments facilitating fund raising by firms, in the benevolent behaviour of the authorities in charge of competition policy during the Reagan administration in the US, while inter nal market completion has become a strong incentive for European firms to reach a true continental dimension in the UE through external growth. However a robust and univocal answer to these questions has not yet been found in spite of its importance not only from the theoretical point of view, but also from the normative one. In fact the correct identification of firms' motivations in pursuing merger and acquisition operations and of their consequences on social welfare would help the choice by administra tive authorities of different possible options in competition and industrial policies.

This book provides a comprehensive overview of the economic and competition policy issues that buyer power creates. Drawing on economic analysis and cases from around the world, it explains why conventional seller side standards and analyses do not provide an adequate framework for responding to the problems that buyer power can create. Based on evidence that abuse of buyer power is a serious problem for the competitive process, the book evaluates the potential for competition law to deal directly with the problems of abuse either through conventional competition law or special rules aimed at abusive conduct. The author also examines controls over buying groups and mergers as potentially more useful responses to risks created by undue buyer power.

This book is a collection of 18 essays that discuss recent major competition policy cases in both the United States and Europe covering mergers, monopolistic practices, and price fixing over the last years.

The most important book on antitrust ever written. It shows how antitrust suits adversely affect the consumer by encouraging a costly form of protection for inefficient and uncompetitive small businesses.
