Essential equilibria.
The connected uniformly hyperstable sets of a finite game are shown to be precisely the essential components of Nash equilibria.
متن کاملOn essential, (strictly) perfect equilibria
It is known that generic games within certain collections of infinite-action normal-form games have only essential equilibria. We point to a difficulty in showing that essential equilibria in generic games are (strictly) perfect, and we identify collections of games whose generic members have only essential and (strictly) perfect equilibria. © 2014 Elsevier B.V.

متن کاملEssential equilibria in normal-form games
A Nash equilibrium x of a normal-form game G is essential if any perturbation of G has an equilibrium close to x. Using payoff perturbations, we show that for games that are generic in the set of compact, quasiconcave, and generalized payoff secure games with upper semicontinuous sum of payoffs, all equilibria are essential. Some variants of this result are also established. © 2009 Elsevier Inc...
متن کاملFurther results on essential Nash equilibria in normal-form games
A Nash equilibrium x of a normal-form game G is essential if any perturbation of G has an equilibrium close to x . Using payoff perturbations, we identify a new collection of games containing a dense, residual subset of games whose Nash equilibria are all essential. This collection covers economic examples that cannot be handled by extant results and subsumes the sets of games considered in the...
متن کاملAdministrative rationing and multiple equilibria
In this paper, we introduce non-interest profit/loss sharing (PLS) banks into a three-period overlapping generations model. Two types, (low- and high quality) investments are assumed and capital accumulation and level of output in the steady state is considered. Then, administrative rationing is introduced to the model. It is shown that the level of capital accumulation and output in equilibriu...
