Overview

The "oligopoly problem"—the question of how prices are formed when the market contains only a few competitors—is one of the more persistent problems in the history of economic thought. In this book Xavier Vives applies a modern game-theoretic approach to develop a theory of oligopoly pricing. Vives begins by relating classic contributions to the field—including those of Cournot, Bertrand, Edgeworth, Chamberlin, and Robinson—to modern game theory. In his discussion of basic game-theoretic tools and equilibrium, he pays particular attention to recent developments in the theory of supermodular games. The middle section of the book, an in-depth treatment of classic static models, provides specialized existence results, characterizations of equilibria, extensions to large markets, and an analysis of comparative statics with a view toward applied work. The final chapters examine commitment issues, entry, information transmission, and collusion using a variety of tools: two-stage games, the modeling of competition under asymmetric information and mechanism design theory, and the theory of repeated and dynamic games, including Markov perfect equilibrium and differential games.

What People are Saying About This

Jonathan H. Hamilton

The clearest presentation of new results on existence of equilibria using lattice theory. An advanced student in industrial organization will find this a great resource on recent developments in oligopoly theory. It really helps prepare a student for research.

Michael Riordan

The great accomplishment of Industrial Organization is the application of game theory to the study of industry conduct. Xavier Vives provides an up-o-date and appreciative guide to that accomplishment.

Joseph Harrington

An exceedingly careful and thorough treatment of the theoretical stock of knowledge on imperfect competition by one of the best oligopoly theorists of his generation. Its extensive use of the theory of supermodular games makes this book truly unique and on the cutting edge. Its comprehensive coverage and attention to theoretical foundations and to proving results rigorously and with utmost generality means that scholars, not just students, will benefit from reading it.
