This page was last edited on 7 Decemberat This equilibrium is usually known as Cournot equilibrium with endogenous entry, or Marshall equilibrium. 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.

Views Read Edit View history. With linear demand and identical, constant marginal cost the equilibrium values are as follows:. It is named after Antoine Augustin Cournot — who was inspired by observing competition in a spring water duopoly.
This article needs additional citations for verification. Equilibrium prices will be:.

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.

Hence with many firms a Cournot ce approximates a perfectly competitive market. 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. Unsourced material may be challenged and removed.
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. Ve is the product of price and quantity and cost is given by the firm’s duopoolio function, so profit is as described above: The state of equilibrium 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.

However, as the number of firms increases towards infinity, the Cournot model cpurnot the same result as in Bertrand model: The profit of firm i is revenue minus cost. Price is a commonly known decreasing function of total output.
The market price is set at a level such that demand cournott the total quantity produced by all firms. 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.
