Journal ArticleDOI
An Existence Result for Discontinuous Games
TL;DR: It is shown that higher semicontinuity, together with a weak form of payoff security, is enough to guarantee the existence of Nash equilibria in compact, quasiconcave normal form games.
Journal ArticleDOI
On the existence of pure-strategy equilibria in large games
TL;DR: In this paper, it was shown that all the above existence results are equivalent and therefore cannot rank the different formalizations of large games, and that all of them are equally strong.
Journal ArticleDOI
Repeated games with one-memory
TL;DR: The extent to which equilibrium payoffs of discounted repeated games can be obtained by 1-memory strategies is studied to establish the following in games with perfect (rich) action spaces: when the players are sufficiently patient, the subgame perfect Folk Theorem holds with 1- memory.
Journal ArticleDOI
Understanding some recent existence results for discontinuous games
TL;DR: In this paper, it was shown that every compact, locally convex, metric, quasiconcave and weakly better-reply secure game has a Nash equilibrium, which is equivalent to the result of Barelli and Soza (On the Existence of Nash Equilibria in Discontinuous and Qualitative Games, University of Rochester, Rochester, 2009).
Journal ArticleDOI
Existence of Nash equilibrium in ordinal games with discontinuous preferences
TL;DR: In this article, the existence of Nash equilibria in games in which players' preferences can be arbitrary binary relations was shown to be true for games with non-ordered preferences.
