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.

Duopolik Proposed since January Views Read Edit View history. The state of equilibrium Price is a commonly known decreasing function of total output.

It is named after Antoine Augustin Cournot — who was inspired by observing competition in a spring water duopoly. Nash equilibrium Subgame perfection Mertens-stable 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 profit of firm i is revenue minus cost. The consequence of this is that in equilibrium, each firm’s expectations of how other firms will act are shown to be correct; when all is revealed, no firm wants to change its output decision.

Cournot competition is an economic model used to describe an industry structure in which companies compete on the amount of output they will produce, which they decide on independently of each other and at the same time.

Topics in game theory. To calculate the Nash equilibrium, the best response functions of the firms must first duo;olio calculated. Each firm takes the quantity set by its competitors as a given, evaluates its residual demand, and then behaves as a monopoly.

When the market is characterized by fixed costs of production, however, we can endogenize the number of competitors imagining that firms enter in the market until their profits are zero. Please help improve this article by adding citations to reliable sources.

Normally the cost functions are treated as common knowledge. Arrow’s impossibility theorem Aumann’s agreement theorem Folk theorem Minimax theorem Nash’s theorem Purification theorem Revelation principle Zermelo’s theorem. In Nash equilibria, both firms will be playing best responses so solving the above equations simultaneously.

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.

The cost functions may be the same or different among firms. This equilibrium is usually known as Cournot equilibrium with endogenous entry, or Marshall equilibrium. This section presents an analysis of the model with 2 firms and constant marginal cost. Revenue is the product of price and quantity and cost is given by the firm’s cost function, so profit is as described above: Hence with many firms a Cournot market approximates a perfectly competitive market.

Equilibrium prices will be:. An essential assumption of this model is the “not conjecture” that each firm aims to maximize profits, based on the expectation that its own output decision will not have an effect on the decisions of its rivals.

This result can be generalized to the case of firms with different cost structures under appropriate restrictions and non-linear demand.

The market price is pushed to marginal cost level. However, as the number of firms increases towards infinity, the Cournot model gives the same result as in Bertrand model: Unsourced material may be challenged and removed.

It has been suggested that Xuopolio monopoly be merged into this article. The market price is set at a level such that demand equals the total quantity produced by all firms.
