The Oligopoly Strategic Behaviour and the Nash Equilibrium

Abstract:

The economic level of the competition can be considered as a mechanism of resources allocation which allows, in many cases, the promotion of the economical efficiency. For this reason the notion of competition was and is related first to the behavior hypothesis of the economical agents and second to the relative hypothesis of the market operation. The economic actors have different behaviors on the real market. Starting with the signification of the rationality hypothesis when the agent’s contentment is directly affected by the other agents’ decisions, the theory of games defines solutions for solving different situations of conflict. Regarding the situation when we have an oligopoly competition, the companies make interdependent decisions in the environment affected by risk and uncertainty. For this reason it is an opportunity to study the structure of oligopoly aid the theory of games. The study of market structures represents a very important problem of the contemporary economy. Starting with the theoretical results that reside in literature regarding the game theory our interest for research was focused on the oligopoly market structure from the theory of game perspective. The oligopoly strategic behaviors were analyzed by Nah equilibrium. The conclusions of the work reveal that using the game theory as reference framework regarding the representation of the economic agents’ on different market structure, opens the way for an expansive field of investigation. The problem of the economic agents is no longer conducting studies for the operation of the perfect competition markets but to analyze the means in which they can coordinate the decisions, in dynamic configurations in a competitive environment affected by risk and uncertainty.
