Model of economic relations of exchange with agreed economic interests for analysis of competitive relations oligopolistic market subjects

The article presents a study of the application of the model of economic relations of exchange with the agreed economic interests of market entities developed by the author for the analysis of competitive relations in the oligopolistic market. The relations of exchange and competition of subjects of the oligopolistic market are the subject of classical models of market behavior of oligopolistic companies (A. Cournot, J. Nash, E. G. Chamberlin, G. Stackelberg, etc.). The model of metabolic processes proposed by the author for analyzing the equilibrium state and evaluating the optimal behavior of oligopolistic competition market entities in a system of coordinated economic interests supplements the analytical capabilities of classical models and makes the analysis more reasonable from the point of view of fairness of economic relations. On the example of a numerical experiment, the features of the behavior of oligopolistic companies for different cases are revealed: Cournot-Nash equilibrium in the system of interests of equivalent duopolists; balance according to the Stackelberg model in the system of interests of the duopolists, represented by the leader and followers; equilibrium according to the model of oligopolistic “limiting pricing” in the system of interests of oligopolists with a competitive environment and free entry...
