This book provides a methodology for the analysis of oligopolistic markets from an equilibrium viewpoint, considering competition within and between groups of firms. It proposes a well-founded measure of competitive toughness that can be used in empirically relevant applications. This measure reflects the weight put by each firm on competition for market share relative to competition for market size – two dimensions of competition involving conflicting and convergent interests, respectively. It further explores several applications, such as the effect of tougher competition on innovation and of output market power on the emergence of involuntary unemployment, as well as the importance of strategic interactions for investment decisions. Relative to the dominant model of monopolistic competition, The Economics of Competition, Collusion and In-between aims to explore an alternative tractable model of firm competition opening the application of oligopoly theory to many fields in economics where general equilibrium features are crucial. It will be relevant to those interested in applied industrial organization, trade, macroeconomics (in particular macrodynamics) and quantitative economics.

A review of the theoretical research on unlawful collusion, focusing on the impact and optimal design of competition law and enforcement. Collusion occurs when firms in a market coordinate their behavior for the purpose of producing a supracompetitive outcome. The literature on the theory of collusion is deep and broad but most of that work does not take account of the possible illegality of collusion. Recently, there has been a growing body of research that explicitly focuses on collusion that runs afoul of competition law and thereby makes firms potentially liable for penalties. This book, by an expert on the subject, reviews the theoretical research on unlawful collusion, with a focus on two issues: the impact of competition law and enforcement on whether, how long, and how much firms collude; and the optimal design of competition law and enforcement. The book begins by discussing general issues that arise when models of collusion take into account competition law and enforcement. It goes on to consider game-theoretic models that encompass the probability of detection and penalties incurred when convicted, and examines how these policy instruments affect the frequency of cartels, cartel duration, cartel participation, and collusive prices. The book then considers the design of competition law and enforcement, examining such topics as the formula for penalties and leniency programs. The book concludes with suggested future lines of inquiry into illegal collusion.

An examination of collusive behavior: what it is, why it is profitable, how it is implemented, and how it might be detected. Explicit collusion is an agreement among competitors to suppress rivalry that relies on interfirm communication and/or transfers. Rivalry between competitors erodes profits; the suppression of rivalry through collusion is one avenue by which firms can enhance profits. Many cartels and bidding rings function for years in a stable and peaceful manner despite the illegality of their agreements and incentives for deviation by their members. In The Economics of Collusion, Robert Marshall and Leslie Marx offer an examination of collusive behavior: what it is, why it is profitable, how it is implemented, and how it might be detected. Marshall and Marx, who have studied collusion extensively for two decades, begin with three narratives: the organization and implementation of a cartel, the organization and implementation of a bidding ring, and a parent company's efforts to detect collusion by its divisions. These accounts—fictitious, but rooted in the inner workings and details from actual cases—offer a novel and engaging way for the reader to understand the basics of collusive behavior. The narratives are followed by detailed economic analyses of cartels, bidding rings, and detection. The narratives offer an engaging entrée to the more rigorous economic discussion that follows. The book is accessible to any reader who understands basic economic reasoning. Mathematical material is flagged with asterisks.

By examining the issue of collusion in EU and US competition law, this book suggests possible strategies for improving the antitrust enforcement against parallelism, by exploiting the most advanced achievements of economic analysis. The book contains a suggested approach to collusion, in ex ante and ex post perspectives. By moving from the analysis of the state of art, in terms of law, case law, and scholarship, Marilena Filippelli analyses inconsistencies and failures in the current antitrust enforcement toward collusion and develops a workable parameter for the issue of collective dominance. The most innovative part of this work goes beyond the analysis itself of collective dominance and involves the interference of arts. 101 and 102. The conclusion is a re-definition of the relationship between those rulesÑfrom dichotomy to redundancy. Finally, the book highlights the antitrust significance of semi-collusion, as a strategy made of collusion and competition. The author considers economic models equaling, as for the effects, collusion and semi-collusion and the case law supporting the qualification of semi-collusion as a species of collusion. The analysis involves both US and EU systems, under the highly topical economic-oriented approach. It also contains an original view of European antitrust prohibitions. Because of its contents and its approach, this book will be attractive to every academic interested in antitrust law. Moreover, the well-documented research on parallelism, involving law, case law and scholarship, makes this book interesting also for competition authorities and antitrust lawyers.

Throughout the world, the rule against price fixing is competition law's most important and least controversial prohibition. Yet there is far less consensus than meets the eye on what constitutes price fixing, and prevalent understandings conflict with the teachings of oligopoly theory that supposedly underlie modern competition policy. Competition Policy and Price Fixing provides the needed analytical foundation. It offers a fresh, in-depth exploration of competition law's horizontal agreement requirement, presents a systematic analysis of how best to address the problem of coordinated oligopolistic price elevation, and compares the resulting direct approach to the orthodox prohibition. In doing so, Louis Kaplow elaborates the relevant benefits and costs of potential solutions, investigates how coordinated price elevation is best detected in light of the error costs associated with different types of proof, and examines appropriate sanctions. Existing literature devotes remarkably little attention to these key subjects and instead concerns itself with limiting penalties to certain sorts of interfirm communications. Challenging conventional wisdom, Kaplow shows how this circumscribed view is less well grounded in the statutes, principles, and precedents of competition law than is a more direct, functional proscription. More important, by comparison to the communications-based prohibition, he explains how the direct approach targets situations that involve both greater social harm and less risk of chilling desirable behavior--and is also easier to apply.

A theoretical and empirical study of the effects of competition across a broad range of industries. Policies to promote competition are high on the political agenda worldwide. But in a constantly changing marketplace, the effects of more intense competition on firm conduct, market structure, and industry performance are often hard to distinguish. This study combines game-theoretic models with empirical evidence from a "natural experiment" of policy reform. The introduction in the United Kingdom of the 1956 Restrictive Trade Practices Act led to the registration and subsequent abolition of explicit restrictive agreements between firms and the intensification of price competition across a range of manufacturing industries. An equally large number of industries were not affected by the legislation. Using data from before and after the 1956 act, this book compares the two groups of industries to determine the effect of price competition on concentration, firm and plant numbers, profitability, advertising intensity, and innovation. The book avoids two problems common to empirical studies of competition: how to measure the intensity of competition and how to unravel the links between competition and other variables. Because the change in the intensity of competition had an external cause, there is no need to measure the intensity of competition directly, and it is possible to identify one-way causal effects when estimating the impact of competition. The book also examines issues such as the industries in which collusion is more likely to occur; the effect of cartels and cartel laws on market structure and profitability; the links between competition, advertising, and innovation; and the constraints on the exercise of merger and antitrust policies.

Information Exchange Between Competitors in EU Competition Law Martin Gassler Competing firms often exchange information in order to make more informed market decisions which can help to overcome market inefficiencies. However, an abundance of legal and economic research as well as case law has shown that information exchange may also enable firms to engage in collusion more readily and sustain it longer. This book is the first to concentrate on this challenging topic of EU competition law in such depth. It focuses on ‘pure’ information exchanges – exchanges that are not ancillary to a wider pro-competitive or anticompetitive conduct – and thoroughly explains the characteristics of such information exchanges, their pro-competitive and anticompetitive effects and discusses all the relevant legal aspects for their assessment. The author provides a robust analytical framework for assessing information exchanges under Article 101 TFEU, focusing on the risk of collusive outcomes and what types of information exchange are particularly harmful. With detailed attention to the leading cases on information exchange, the analysis examines the most important aspects for assessing information exchange between competitors, in particular: the concept of a concerted practice; the concepts of a restriction by object and effect, including their similarities and differences; the importance of evidentiary issues; the issue of signalling via advance public announcements; factors that facilitate collusion; efficiencies of information exchange, including market transparency; the legal challenges of tackling mere parallel conduct; facilitative practices in the Commission Guidelines, including the Horizontal Cooperation Guidelines; and safe harbours for certain types of information exchange. The book offers clear guidance on how to identify and thus distinguish information exchange that restricts competition by its object and information exchange that restricts competition (only) by its effects. It offers practical solutions to some of the perceived issues when assessing information exchanges. With its wealth of analysis not available from other sources, this concise yet comprehensive review of a much-debated topic in competition law offers clear guidance for practitioners in assessing the issues surrounding information exchange. The book will also be welcomed by competition law academics, competition lawyers and competition authority officials throughout Europe.
