A Nash equilibrium can also be seen as a Cournot-Nash equilibrium, though this is debated because Cournot provided a specific application, not a general formulation. In my view, another of Nash's fundamental contributions stands out when contrasting him to Cournot. Cournot treated economic...

A "dispersion" specifies the relative probability between any two elements of a finite domain. It thereby partitions the domain into equivalence classes separated by infinite relative probability. The paper's novelty is to numerically represent not only the order of the equivalence classes, but...

This paper provides a general model for the study of strategic knowledge sharing in any finite Bayesian game. Unlike earlier papers on strategic information revelation, higher-order uncertainties can be incorporated into the model. We propose an equilibrium concept, called knowledge equilibrium,...

The aim of this paper is to show the relation among equilibria in models with different levels of rationality. The different levels of rationality are defined in terms of the number of iterations that a player can perform with a simple rule for updating beliefs. It is shown that the rule...
