The distinctive feature of the different oligopoly models is the way they attempt to capture the interdependence of firms in the market. Oligopoly theory makes heavy use of game theory to model the behavior of oligopolies: Stackelberg’s duopoly.

Oligopoly – Model Specification Games and Decisions Jan Zouhar 4 to make the analysis simple, we’ll make several assumptions: 1. single-product model: oligopolists produce a single type of homogenous product 2. one strategic variable: firms decide about prices or output levels 3. static model: single-period analysis only in dynamic models, there are more diverse strategic options: stream The Bertrand duopoly model indicates that firm A maximizes profit by charging $64, and firm B maximizes profit by charging $56. The logic is simple: if the price set by both firms is the same but the marginal cost is lower, there will be an incentive for both firms to lower their prices and seize the market. <> 1. In the Bertrand model of duopoly, each firm sets its price, believing that the other's price will not change.When both firms have identical production functions and produce with constant returns to scale, the Bertrand equilibrium price is equal to marginal cost.
