On strategic stability in discontinuous games

نویسنده

چکیده

We identify a class of discontinuous normal-form gameswhosemembers possess strategically stable sets, defined according to an infinite-game extension of Kohlberg and Mertens’s (1986) equilibrium concept, and show that, generically, a set is stable if and only if it contains a single Nash equilibrium. © 2011 Elsevier B.V.

On Equilibrium Refinement for Discontinuous Games

In moving from finite-action to infinite-action games, standard refinements of the Nash equilibrium concept cease to satisfy certain “natural” properties. For instance, perfect equilibria in compact, continuous games need not be admissible. This paper highlights additional properties of two standard refinement specifications that are not inherited by supersets of the set of finite games. The an...

Strategic Approximations of Discontinuous Games

An in…nite game is approximated by restricting the players to …nite subsets of their pure strategy spaces. A strategic approximation of an in…nite game is a countable subset of pure strategies with the property that limits of all equilibria of all sequences of approximating games whose …nite strategy sets eventually include each member of the countable set must be equilibria of the in…nite game...

Dynamic system of strategic games

Maybe an event can't be modeled completely through one game but there is more chance with several games. With emphasis on players' rationality, we present new properties of strategic games, which result in production of other games. Here, a new attitude to modeling will be presented in game theory as dynamic system of strategic games and its some applications such as analysis of the clash betwe...

A Note on the Existence of Nash Equilibrium in Games with Discontinuous

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...

A review on symmetric games: theory, comparison and applications

Game theory models decision makers' behaviors in strategic situations. Since the structures of games are different, behavior and preferences of the players are different in various types of game. This paper reviews various situations of games. Here, characteristics of some common games are discussed and compared. Specifically, we focus on a group of games called symmetric games including Prison...
