Oligopoly Pricing : Old Ideas and New Tools Paperback / softback
Part of the The MIT Press series
Paperback / softback
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.
