Cournot Oligopoly with Network Effects
The nature of competition is quite different in network industries as compared to the other, more traditional, ones. The purpose of the present paper is to thoroughly examine the implications of these differences as reflected in the dependence of equilibrium outputs, price and profits on industry concentration. We restrict the analysis to oligopolistic competition amongst firms in a market char...
متن کاملMultiproduct Cournot Oligopoly
We present a general model of oligopolistic quantity competition in which each firm is able to produce multiple quality-differentiated products. We identify a tight relationship between asymmetries in the technological capabilities of firms and the equilibrium structure of product lines. The qualities offered by a firm group naturally into brands, and the positions of such brands are determined...
متن کاملCommunication in Cournot oligopoly
We study communication in a static Cournot duopoly model under the assumption that firms have unverifiable private information about their costs. We show that cheap talk between the firms cannot transmit any information. However, if the firms can communicate through a third party, communication can be informative even when it is not substantiated by any commitment or costly actions. We exhibit ...
متن کاملInformation Advantage in Cournot Oligopoly
-----------------------------We model an oligopolistic industry where a number of firms that are asymmetrically informed about the environment compete via quantities, and we study how the information available to a firm affects its equilibrium profits. Indeed we find that if all firms have access to the same constant returns to scale technology, in any Bayesian equilibrium the information advan...
متن کاملCournot Oligopoly and Concavo-Concave Demand
The -firm Cournot model with general technologies is reviewed to derive generalized and unified conditions for existence of a pure strategy Nash equilibrium. Tight conditions are formulated alternatively (i) in terms of concavity of two-sided transforms of inverse demand, or (ii) as linear constraints on the elasticities of inverse demand and its first derivative. These conditions hold, in pa...
