On the Existence of Nash Equilibria in Discontinuous and Qualitative Games

چکیده
We provide a unified approach to existence of Nash equilibria in (possibly) discontinuous and qualitative games. We combine the idea of a local continuous selection of each player’s strict upper contour set from the qualitative games literature with the “better reply security” idea (Reny [15]) of activating different players locally from the discontinuous games literature, together with a weak notion of convexity of preferences. The result generalizes a number of previous conditions in the literature.

متن کاملOn the Existence of Approximated Equilibria and Sharing-Rule Equilibria in Discontinuous Games∗
New relaxations of the Nash equilibrium concept are shown to exist in any strategic game with discontinuous payoff functions. The new concepts are used (1) to show the equivalence between Reny’s better-reply security condition [28] and Simon-Zame’s endogenous tie-breaking rule equilibrium concept [32], (2) to obtain conditions for the existence of approximated equilibria in a class of discontin...
متن کاملOn the existence of equilibria in discontinuous games: three counterexamples
We study whether we can weaken the conditions given in Reny [4] and still obtain existence of pure strategy Nash equilibria in quasiconcave normal form games, or, at least, existence of pure strategy ε−equilibria for all ε > 0. We show by examples that there are: 1. quasiconcave, payoff secure games without pure strategy ε−equilibria for small enough ε > 0 (and hence, without pure strategy Nash...

This paper generalises the approach taken by Dasgupta & Maskin (1986) and Simon (1989) and provides necessary and su¢ cient conditions for the existence of pure and mixed strategy Nash equilibrium in games with continuous strategy spaces and discontinuous payo¤ functions. The conditions can be applied widely, and examples for existence of pure strategy and monotonic equilibria in First-Price au...
متن کاملExistence of pure Nash equilibria in discontinuous and non quasiconcave games
In a recent but well known paper, Reny has proved the existence of Nash equilibria for compact and quasiconcave games, with possibly discontinuous payoff functions. In this paper, we prove that the quasiconcavity assumption in Reny’s theorem can be weakened: we introduce a measure allowing to localize the lack of quasiconcavity, which allows to refine the analysis of equilibrium existence.
