Equilibrium selection through p_u -dominance

The paper introduces and discusses the concept of p_u-dominance in the context of finite games in normal form. It then presents the p_u-dominance criterion for equilibrium selection. The p_u-dominance criterion is inspired by and closely related to the p-dominance criterion originally proposed by Morris et al. (Econometrica 63:145–157, 1995). However, there are games in which the two criteria lead to different refinements. We provide sufficient conditions under which equilibrium selection through p_u-dominance is weakly finer (respectively, coarser) than equilibrium selection through p-dominance.
