Using the approach of Tian (2009) which characterizes the existence of Nash equilibria in strategic form games, we give sufficient conditions for the existence of Pareto efficient Nash equilibria in games where discontinuities on payoffs are allowed.

In the recent paper by the author [Scalzo, V., 2010. Pareto efficient Nash equilibria in discontinuous games. Economics Letters 107, 364–365], a class of discontinuous games where efficient Nash equilibria exist has been defined. In the present paper, we complete the previous investigation and...
