Each firm chooses its quantity as the best response to the quantity chosen by the other(s). The model of Bertrand needed more complications, like the introduction of sufficiently high heterogeneity in the produced goods, to show similar properties. D. rivals will follow the learning curve. Ability to set price: Oligopolies are price setters rather than price takers. There are two primary types of duopolies: the Cournot Duopoly (named after Antoine Cournot) and the Bertrand Duopoly (named after Joseph Bertrand).

Bertrand’s equilibrium occurs when P 1 =P 2 =MC, being MC the marginal cost, yielding the same result as perfect competition. II.

Bertrand, who presented the model of price competition in a duopoly market in 1883. Cournot’s model of oligopoly is one of the oldest theories of the behaviour of the individual firm and relates to non-collusive oligopoly. Perhaps the best known is the Cournot model. The Bertrand duopoly model indicates that firm A maximizes profit by charging $64, and firm B maximizes profit by charging $56. When these firms get together and agree to set prices and outputs so as to maximise total industry profits, they are known as a cartel.
