Oligopoly Theory

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.

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.

The separation between ownership and control has become common practice over the last century, in most medium and large firms across the world. Throughout the twentieth century, the theory of the firm and the theory of industrial organization developed parallel and complementary views on managerial firms. This book offers a comprehensive exposition of this debate. In its survey of strategic delegation in oligopoly games, An Economic Theory of Managerial Firms is able to offer a reinterpretation of a range of standard results in the light of the fact that the control of firms is generally not in the hand of its owners. The theoretical models are supported by a wealth of real-world examples, in order to provide a study of strategic delegation that is far more in-depth than has previously been found in the literature on industrial organization. In this volume, analysis is extended in several directions to cover applications concerning the role of: managerial firms in mixed market; collusion and mergers; divisionalization and vertical relations; technical progress; product differentiation; international trade; environmental issues; and the intertemporal growth of firms. This book is of great interest to those who study industrial economics, organizational studies and industrial studies.

Industrial production and consumption patterns rely heavily on the intensive use of both renewable and non-renewable resources and the consequences for the environment can be serious. Following a long period of time where the profit incentives of firms have prevailed over preservation of the environment and the world’s natural resources, a new consensus has emerged concerning the need to regulate firm behaviour, aimed at ensuring the sustainability of the economic system in the long run. This book offers an exhaustive overview of current economic debate about these topics, taking modern oligopoly theory as a benchmark. The first part of the book covers static models dealing with incentives for green research and development, Pigovian taxation, cartels, environmental quality and international trade, as well as the role of corporate social responsibility, public firms and consumer environmental awareness as endogenous regulatory instruments. Then, the author moves on to examine the role of time while drawing from optimal control and differential game theory. This opens the way to the discussion of fair discount rates to ensure the welfare of future generations, as well as the long run sustainability of production and consumption patterns.

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 book develops a theory that radically reconceptualizes the economic forces producing regional change and tests it empirically for a set of fifteen sectors in the U.S. It offers a pioneering approach which should enable planners and managers to better cope with baffling changes in the current economic viability of regions. The dramatic shifts in heartland regional economies in the U.S. and other advanced industrial countries have thrown into question the ability of capitalist development to produce permanent growth, economic well being, and balanced regional development. This book develops a theory that radically reconceptualizes the economic forces producing regional change and tests it empirically for a set of fifteen sectors in the U.S. It offers a pioneering approach which should enable planners and managers to better cope with baffling changes in the current economic viability of regions. Traditional theories of regional development have failed to account for innovation and longrun structural change. They have ignored the role of corporate strategy and the existence of market power. Markusen's profit-cycle theory provides a key to understanding how, why, and when a region's leading industries undergo major changes. The theory is synthetic, building upon Schumpeterian and Marxist work on innovation and capitalist dynamics, upon the product cycle theories of business economists, and upon theories of oligopolistic behavior. Markusen argues that changing sources of profitability along an industry's evolutionary path will first concentrate and later disperse production geographically, setting in motion a methodically destabilizing process for regional economies. The profit-cycle theory is tested in depth against the steel sector's experience over a century, and against the experiences of sectors in different stages of development, ranging from innovative ones like semiconductors and computers, to mature and troubled sectors like automobiles, textiles, and lumber. The temporal and crosssectional data drawn from the census of manufactures support the theory and its spatial hypotheses. In a final chapter Markusen explores the implications of the research for regional development.
