New Nash Equilibrium Based on Generic Risk Element Transmission Theory
Nash equilibrium is the foundation of traditional game theory, while the benefits of game players under the Nash equilibrium are constant, so the core idea of generic risk transmission was applied to traditional static game. Accordingly a risk static game model, in which the benefits of players were subject to triangular distribution, was constructed. Then we obtained different equilibrium states under the different risk types of players. Furthermore, the classic Prisoners’ Dilemma was used to demonstrate the practice value of risk game. Through analyzing and solving the risk Prisoners’ Dilemma model which changed from the classic Prisoner's Dilemma model according to actual situation, the Pareto improvement strategy combination could be achieved. The new equilibrium result can give an appropriate explanation why there is always some prisoners conceal the corpus delicti in adventure
