Oligopoly – Equilibrium The oligopolist needs to choose an appropriate response to the rivals’ actions similarly, rivals also need to anticipate the firm’s response and act accordingly interactive setting . Common oligopoly models include the dominant firm model, Cournot-Nash model, and It then examines several non-collusive oligopoly models including Cournot's, Bertrand's, Edgeworth's, and Stackelberg's models. For the Cournot duopoly example, the document calculates that with two identical firms each with a cost of C(q)=2q and an inverse demand function of P(Q)=9-Q, the Cournot Bertrand models and reports no cases in which the Bertrand model is applied to the homogeneous product case.

Instead, firms fix a price on the inelastic portion of the demand curve called the limit price, which is the highest price that deters new firm entry. Theoretical Background (1) • More recently, authors have begun to consider the case where duopolists might choose different strategic variables, that is, a “Cournot–Bertrand” type model where one firm competes in output and the other competes in price. Once we introduce more realistic assumptions the competition softens and the equilibrium price is higher than marginal cost The oligopoly models do not have to be the same for all industries. com - id: 1ac595-ZDc1Z We have seen that Oligopoly is a situation where there are just a few firms.

The document outlines two models of oligopoly - the traditional kinked demand curve model Price determination under oligopoly can occur through independent pricing, collusive pricing, or price leadership. 4. In Bertrand firms still react to the actions/strategies of the other firm but now the firm makes pricing decisions rather than output decisions. 16.

The Bertrand model assumes that firms in an oligopoly compete on price rather than quantity. It provides examples and assumptions of each model. Each firm independently sets its price in order to maximize profits.
