Endogenous Stackelberg Leadership with Uncertain Information

摘要

In the Bayesian game models, the uncertainty is described with probability, but sometimes the uncertainty in practice is given by some fuzzy parameters, and the objectives of players may be not to maximize the expected payoffs. In this paper, a new subjective equilibrium is given for fuzzy games. We make a powerful comparison with Bayesian and equilibria for Stackelberg duopoly game with fuzzy costs. It is showed that endogenous Stackelberg leadership is related with not only marginal costs but also beliefs of the firms.
