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.

Suppose the industry has the following price structure: Simple models of competitionpage 6, Dept.
The market price is pushed to marginal cost level. The cost functions may be the same or different among firms. Revenue is the product of price and quantity and cost is given by the firm’s cost function, so profit is as described above: Economics models Non-cooperative games Competition economics Oligopoly.
From Wikipedia, the free encyclopedia. Views Read Edit View history. Topics in game theory. This section presents an analysis of the model with 2 firms and d marginal cost. However, as the number of firms increases towards infinity, the Cournot model gives the same result as in Bertrand model: It has been suggested that Complementary monopoly be merged into this article.
To calculate the Nash equilibrium, the best response functions of the firms must first be calculated. This article needs additional citations for verification.

The profit of firm i is revenue minus cost.
Price is a commonly known decreasing function of total output. This equilibrium is usually known as Cournot equilibrium with endogenous entry, or Marshall equilibrium.

These are the firms’ best response functions. Arrow’s impossibility theorem Aumann’s agreement theorem Folk se Minimax theorem Nash’s theorem Purification theorem Revelation principle Zermelo’s theorem. 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.
Discuss Proposed since January Each firm takes the quantity set by its competitors as a given, evaluates its residual demand, and then behaves as a monopoly.
It is named after Antoine Augustin Cournot — who was inspired by observing competition in a spring water duopoly.
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. This result can be generalized to the case of firms with different cost structures under appropriate restrictions and non-linear demand.
In Nash equilibria, both firms will be playing best responses so solving the above equations simultaneously. This page was last edited on 7 Decemberat Unsourced material may be challenged and removed.
The market price is set at a level such that demand equals the fuopolio quantity produced by all firms. With linear demand and identical, constant marginal couront the equilibrium values are as follows:. 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.
The state of equilibrium Equilibrium prices will be:. Retrieved from ” https:
