Topics in game theory. 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. Discuss Proposed curnot January Each firm takes the quantity set by its competitors as a given, evaluates its residual demand, and then behaves as a monopoly.

Antoine Augustin Cournot cojrnot 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.

It has been suggested that Complementary monopoly be merged into this article.

Duopolio di Stackelberg – Wikipedia

In Nash equilibria, both firms will be playing best responses so solving the above equations simultaneously. This article needs additional citations for verification. It is named after Antoine Augustin Cournot — who was inspired by observing competition in a spring water duopoly. Equilibrium prices will be:. Arrow’s impossibility theorem Aumann’s agreement theorem Folk theorem Minimax theorem Nash’s theorem Purification theorem Revelation principle Zermelo’s theorem.


With linear demand and identical, constant marginal cost the equilibrium values are as follows:.

However, as the number of firms increases towards infinity, the Cournot model gives the same result as in Bertrand model: 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.

Hence with many firms a Cournot market approximates a perfectly competitive market. From Dduopolio, the free encyclopedia.

The profit of firm i is revenue minus cost. 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 equilibrium is usually known as Cournot equilibrium with endogenous entry, or Marshall equilibrium. 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 duopoilo revealed, no firm wants to change its output decision. Suppose the industry has the following price structure: Revenue is the product of price and quantity and cost is given by the firm’s cost function, so profit is as described above: Price is a commonly known decreasing function of total output.

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. The market price is set at a level such that demand equals the total quantity produced by all firms. October Learn how and when to remove this template message.
