• TITLE: Symmetric Stability in Symmetric Games

  AUTHORS: Andreas Hefti

  KEYWORDS: Symmetric Games, Symmetric Equilibrium, Stability, Uniqueness

  JOURNAL NAME: Theoretical Economics Letters, Vol.6 No.3, June 9, 2016

  ABSTRACT: The idea of symmetric stability of symmetric equilibria is introduced which is relevant, e.g., for the comparative-statics of symmetric equilibria with symmetric shocks. I show that symmetric stability can be expressed in a two-player reduced-form version of the N-player game, derive an elementary relation between symmetric stability and the existence of exactly one symmetric equilibrium, and apply symmetric stability to a two-dimensional N-player contest.
