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...

This book gives a comprehensive survey and complete mathematical development of the theory of multi-product oligopolies. Existence and uniqueness of the Nash-Cournot equilibria as well as its stability are analysed for the multi-product Cournot model and for its variants such as labor-managed...

The effects of change in the market (inverse) demand function are systematically analysed for Cournot oligopoly without product differentiation. The general comparative-static results are stated using the original data on firms' cost functions and inverse demand function. Three special models...

Labor-managed Cournot oligopoly with or without product differentiation is analyzed. First, the existence of Cournot equilibrium which is not necessarily unique is proved under general conditions based on the Brouwer fixed point theorem, which does not provide a direct computer method for...
