In this book a rigorous, systematic, mathematical analysis is presented for oligopoly with multi-product firms in static as well as dynamic frameworks in the light of recent developments in theories of games, oligopoly and industrial organization. The general results derived in this book on oligopoly with multi-product firms contain, as special cases, all previous results on oligopoly with single product as well as oligopoly with product differentiation and single product firms. A constructive nu- merical method is given for finding the Cournot-Nash equilibrium, which may be extremely valuable to those who are interested in numerical analysis of the effects of various industrial policies. A sequential adjustment process is also formulated for finding the equilibrium. Dynamic adjustment processes have two versions, one with a discrete time scale and the other with a continuous time scale. The stability of the equilibrium is thoroughly investigated utilizing powerful mathematical results from the stability and linear algebra literature. The methodology developed for analyzing stability proves to be useful for dynamic analysis of economic models.

James Friedman provides a thorough survey of oligopoly theory using numerical examples and careful verbal explanations to make the ideas clear and accessible. While the earlier ideas of Cournot, Hotelling, and Chamberlin are presented, the larger part of the book is devoted to the modern work on oligopoly that has resulted from the application of dynamic techniques and game theory to this area of economics. The book begins with static oligopoly theory. Cournot's model and its more recent elaborations are covered in the first substantive chapter. Then the Chamberlinian analysis of product differentiation, spatial competition, and characteristics space is set out. The subsequent chapters on modern work deal with reaction functions, advertising, oligopoly with capital, entry, and oligopoly using noncooperative game theory. A large bibliography is provided.

This state-of-the-art collection of papers on the theory of Cournotian competition focuses on two main subjects: oligopolistic Cournot competition and contests. The contributors present various applications of the Cournotian Equilibrium Theory, addressing topics such as equilibrium existence and uniqueness, equilibrium structure, dynamic processes, coalitional behavior and welfare. Special emphasis is placed on the aggregative nature of the games that are relevant to such theory. This contributed volume was written to celebrate the 80th birthday of Prof. Koji Okuguchi, a pioneer in oligopoly theory.

The theory of price and quality decision-making in industries with a few firms which recognize their mutual interdependence is of increasing interest to economists and policy makers. This book introduces a novel theory of that decision-making, based upon the notion of the industry as a community of agents who are involved in both competitive and cooperative relationships. It develops theories and illustrates methodological approaches to the analysis of price and quality decision-making in such instances of a 'rivalrous consonance of interests' among firms.

This paper develops a general equilibrium model of oligopolistic multiproduct firms conducting trade between asymmetric countries, in which heterogeneous entrants choose their product ranges and outputs. We show that there are fewer exporters in the larger country, and each produces a wider range of products but exports fewer varieties. We also show that while trade liberalization increases the total number of consumed varieties, it decreases the total number of firms and may reduce the product range of each firm.

Applies a modern game-theoretic approach to develop a theory of oligopoly pricing. The text relates classic contributions to the field of modern game theory and discusses basic game-theoretic tools and equilibrium, paying particular attention to developments in the theory of supermodular games.

This is the first book to comprehensively examine the asymptotic behavior of dynamic monopolies, duopolies, and oligopolies where firms face information and implementation delays. It considers discrete and continuous timescales, continuously distributed delays, as well as single and multiple delays. It also discusses models with linear and hyperbolic price functions in three types of oligopolies: Cournot competition with quantity-adjusting firms, Bertrand competition with price-adjusting firms, and mixed oligopolies with both types of firms. In addition to the traditional Cournot-Nash equilibria, it introduces cases of partial cooperation are also introduced, leading to the analysis of cartelizing groups of firms and possible governmental actions against antitrust behavior. Further, the book investigates special processes for firms learning about the uncertain price function based on repeated market information. It addresses asymptotic properties of the associated dynamic systems, derives stability conditions, identifies stability switching curves, and presents in global analyses of cases of instability. The book includes both theoretical results and computer studies to illustrate and verify the theoretical findings.

This book outlines the core concept of the theory of mixed oligopoly and presents recent results that have arisen in a mixed oligopolistic market. The wave of privatization since the 1980s has taken the development of the theory of mixed oligopoly in several directions. Although the main concern of the theory of mixed oligopoly focuses on the effect of regime change—especially privatization of a public firm—on social welfare, existing studies have not considered the difference in economic environments. With drastic changes in economic environments along with economic development in recent years, the domestic and foreign markets have become more and more integrated, firms have become concerned about corporate social responsibility, and governments or politicians have had various interests and preferences. Against that background, this book revisits the question of how privatization affects social welfare by incorporating regional and international interdependency and investigates how firms’ activities for corporate social responsibility, governments’ preferences, and political economic situations affect the market circumstance in a mixed oligopoly. The dynamic aspect of privatization is also investigated.
