## Duopolio di Stackelberg

The profit of firm i is revenue minus cost. These are the firms’ best response functions.

Unsourced material may be challenged and removed. Duopooio 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. Each firm takes the quantity set by its competitors as a given, evaluates its residual demand, and then behaves as a monopoly.

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 article needs additional citations for verification. The state of 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.

However, as the number of firms increases towards infinity, the Cournot model gives the same result as in Bertrand model: Discuss Proposed since January This equilibrium is usually known as Cournot equilibrium with endogenous entry, or Marshall equilibrium. To calculate the Nash equilibrium, the best response functions of the firms must first be calculated.

Please help improve this article by adding citations to reliable sources. 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.

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. Views Read Edit View history. The market price is set at a level such that demand equals the total quantity produced by all firms. The market price is pushed to marginal cost level.

Normally the cost functions are treated as common knowledge.

It is named after Antoine Augustin Cournot — who was inspired by observing competition in a spring water duopoly.

Suppose the industry has the following price structure: In Nash equilibria, both firms will be playing best responses so solving the above equations simultaneously. Cooperative game Determinacy Escalation of commitment Extensive-form game First-player and second-player win Game complexity Graphical game Hierarchy of beliefs Information set Normal-form game Preference Sequential game Simultaneous game Simultaneous action selection Solved game Succinct game.

It has been suggested that Complementary monopoly be merged into this article. 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. Hence with many firms a Cournot market approximates a perfectly competitive market.

Euopolio cost functions may be the same or different among firms. This section presents an analysis of the model with 2 cournnot and constant marginal cost.
