Nash Equilibria on Soft Information Control Games--Based on Banking Industry in China

Abstract

In the competition of banking sector in China, to maximize the amount of soft information control is an important goal. In an n-dimensional Euclidean space, there exists Nash equilibrium for two different banks in the competition of soft information control. Keeping the same competitive strategy is the best response to each other's actions of the two banks. Further analysis is based on the incomplete information dynamic game between various branches of the same bank. The Nash equilibrium solution for the first mover is to design strategy based on market information, while the followers’ optimal strategy is to imitate the first mover’s policy, whatever knowledge that they may obtain.
