Cournot's model of competition is typically presented for the case of a duopoly market structure; the following example provides a straightforward analysis of the Cournot model for the case of Duopoly. Therefore, suppose we have a market consisting of only two firms which we will call firm 1 and firm 2.
A Cournot duopoly is a model of strategic interaction between two firms where they simultaneously choose their output levels, assuming the rival's output level is fixed. The firms compete on quantity, and each firm attempts to maximize its profit given the other firm's output level.
The Cournot duopoly model developed in his book also introduced the concept of a (pure strategy) Nash equilibrium, the reaction function and best-response dynamics. Cournot believed that economists must utilize the tools of mathematics only to establish probable limits and to express less stable facts in more absolute terms.
In 1838, Antoine Augustin Cournot provided a model of competition in oligopolies. Though he did not refer to it as such, he presented a solution that is the Nash equilibrium of the game in his Recherches sur les principes mathématiques de la théorie des richesses ( Researches into the Mathematical Principles of the Theory of Wealth ).
Cournot quantity competition, one of the first models of oligopoly markets was developed by Augustin Cournot in 1835. In Cournot’s model, there are two firms and each firm selects a quantity to produce, and the resulting total output determines the market price. [9]
The first use of the Nash equilibrium was in the Cournot duopoly as developed by Antoine Augustin Cournot in his 1838 book. [4] Both firms produce a homogenous product: given the total amount supplied by the two firms, the (single) industry price is determined using the demand curve.
Solutions to the Paradox attempt to derive solutions that are more in line with solutions from the Cournot model of competition, where two firms in a market earn positive profits that lie somewhere between the perfectly competitive and monopoly levels. Some reasons the Bertrand paradox do not strictly apply: Capacity constraints. Sometimes ...
