Regularity and Stability in Monotone Bayesian Games

  • Alan Beggs
  • A.W. Beggs

This paper defines regular and weakly regular equilibria for monotone Bayesian games with one-dimensional actions and types. It proves an index theorem and provides applications to uniqueness of equilibrium. It also provides analyses of stability with respect to perturbations and dynamic stability.
