Bertrand’s (1883) review of Cournot (1838) Bertrand suggested a model in which symmetric price-setting duopoly firms produce a homogenous product at constant marginal cost The resulting (Nash) equilibrium in which price equals marginal cost seems unreasonable As stated
The Cournot and Bertrand Models of Industry Equilibrium Now we’re going to remove the assumption of price-taking behavior by rms We’ll begin with the elementary theory of the rm and then we’ll apply the theory to the case of a monopoly Then we’ll move on to strategic behavior and equilibrium when there are multiple rms in a market
Cournot Versus Bertrand: A Dynamic Resolution 1: Introduction Formal analysis of oligopoly has focussed on two basic models: Cournot and Bertrand Cournot analysis assumes that a Þrm determines its sales while price is determined by some unspeciÞed agent so that market demand equals the total amount o?ered Bertrand ana-
(i e Cournot dominates Bertrand behavior and Cour-not-Bertrand behavior) More recently Tremblay et al [2] show how different institutional and technological conditions can change firm payoffs so that Bertrand be-havior or Cournot-Bertrand behavior becomes optimal 1 Given that there are many theoretical possibilities
This study examines and compares output and R&D subsidy policies between Cournot and Bertrand competitions with R&D activities We show that (i) firms invest more (less) in R&D and the government grants more (less) subsidies under Cournot than Bertrand competition with output (R&D) subsidy policies
theoretical analysis of Bertrand and Cournot competition in two-sided markets having both consumers and producers Our results can help explain and predict the real-world performance of similar mechanisms 1 2 Theoretical motivation By analyzing Bertrand and Cournot competition we address our main question which is theoretical At the most
I Introduction For decades the convergence properties of Bertrand and Cournot oligopolies have been themes of continuing interest among economists In Bertrand markets price choices are strategic complements meaning that high expected rival prices induce high optimal seller price responses
