This section presents an analysis of the model with 2 firms and constant marginal cost. Please help improve this article by adding citations to reliable sources.

Suppose the industry has the following price structure: However, as the number of firms increases towards infinity, the Cournot model gives the same result as in Bertrand model: Nash equilibrium Subgame perfection Cohrnot equilibrium Bayesian Nash equilibrium Perfect Bayesian equilibrium Trembling hand Proper equilibrium Epsilon-equilibrium Correlated equilibrium Sequential equilibrium Quasi-perfect equilibrium Evolutionarily stable strategy Risk dominance Core Shapley value Pareto efficiency Gibbs equilibrium Quantal response equilibrium Self-confirming equilibrium Strong Nash equilibrium Markov perfect equilibrium.

The state of equilibrium The cost functions may be the same or different among firms. The market price is pushed to marginal cost level. Antoine Augustin Cournot first outlined his theory of competition in his volume Recherches sur les Principes Mathematiques de la Theorie des Richesses as a way of describing the competition with a market for spring water dominated by two suppliers a duopoly.

Price is a commonly known decreasing function of total output. The Cournot Theorem then states that, in absence of fixed costs of production, as the number of firms in the market, Ngoes to infinity, market output, Nqgoes to the competitive level and the price converges to marginal cost.
