متن کاملCoarse correlated equilibria in linear duopoly games
For duopoly models, we analyse the concept of coarse correlated equilibrium using simple symmetric 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.
متن کاملOn rational belief equilibria
We study equilibria in which agent's belief are rational in the sense of Kurz 1-1994]. The market is formulated by specifying a stochastic demand function and a continuum of producers, each with a quadratic cost function who must select their output before knowing prices. Holding Rational Beliefs about future prices, producers maximize expected profits. In a Rational Belief Equilibrium (RBE) ag...
متن کاملUniqueness of Nash equilibria in a quantum Cournot duopoly game
A quantum Cournot game whose classical form game has multiple Nash equilibria is examined. Although the classical equilibria fail to be Pareto optimal, the quantum equilibrium exhibits the following two properties: (i) if the measurement of entanglement between strategic variables chosen by the competing firms is sufficiently large, the multiplicity of equilibria vanishes, and (ii) the more str...
متن کاملAmbiguity and rational expectations equilibria∗
This paper proves the existence and robustness of partially-revealing rational expectations equilibria (REE) when this equilibrium concept is expanded to allow for some agents to have preferences that display ambiguity aversion. Furthermore, the generic existence of fullyrevealing REE is proven for a commonly-used subset of the class of ambiguity averse preferences. This finding illustrates tha...
