In view of the above research, this paper firstly establishes a game model for the telecom carrier and the third party payment company and obtains the Nash equilibrium by solving the model, secondly acquires the constraint conditions of mobile payment between the two parties through analysis of the influencing factors of the two parties, and finally draws the appropriate application model (Barkhordari et al.
The Nash equilibrium solution for the symmetric duopoly model recommends that two firms charge a price equal to the common marginal cost of production (Tirole 1988, 210).
According to Jury's stability criterion, conditions (16) can be got which shows that the stability of the Nash equilibrium is determined by adjusting parameters ([k.
A Nash equilibrium was originally formulated by Cournot (1838) in the context of an oligopoly model, so an equilibrium point might also be seen as a Cournot-Nash equilibrium.
In section three the regulated circular model is analysed in order to verify the equivalence of the games and concludes by seeking for the existence of Nash equilibrium in prices.
A Nash equilibrium occurs when both players are playing the best possible response they can, given the actions of the other player.
In this study the Nash equilibrium is achieved through the rational consideration of administrators and academic staff who fall into a prisoner's dilemma, one of the best known game strategies in which it is demonstrated that two people might not cooperate even if it is in both their best interests to do so (Osborne, 2003).
