Coarse correlated Equilibria in Linear Duopoly Games

  • Indrajit Ray
  • Sonali Sen Gupta

For duopoly models, we analyse the concept of coarse correlated equilibrium using simplesymmetric devices that the players choose to commit to in equilibrium. In a linear duopoly game, we prove that Nash-centric devices, involving a sunspot structure, are simple symmetric coarse correlated equilibria. Any small unilateral perturbation from such a structure fails to be an equilibrium.
