(Weak) Correlation and Sunspots in Duopoly
AbstractFor duopoly models, we consider the notion of weak correlation using simple symmetric devices that the players choose to commit to in equilibrium. In a linear duopoly game, we prove that Nashcentric devices involving a sunspot structure are simple symmetric weak correlated equilibria. Any small perturbation from such a structure fails to be an equilibrium.
