WebModel misspecification is a critical issue in many areas of theoretical and empirical economics. In the specific context of misspecified Markov Decision Processes, Esponda and Pouzo (2024) defined the notion of Berk-Nash equilibrium and established its existence in the setting of finite state and action spaces. However, many substantive applications … http://people.tamu.edu/~gtian/Nash-Strong-Nessah-Tian-11-02.pdf biography waylon jennings

On the existence of pure-strategy Nash equilibrium

WebThis paper studies the existence of strong Nash equilibrium (SNE) in general economic games. SNE introduced by Aumann [1959] is deﬁned as a strategic proﬁle for which no subset of players has a joint deviation that strictly beneﬁts all of them, while all other players are expected to main- tain their equilibrium strategies. WebNash (1950)’s celebrated existence theorem asserts that every ﬂnite normal- form game has a mixed strategy equilibrium. However, in many contexts mixed strategies are unappealing and hard to interpret, leading naturally to the question of the existence of pure strategy Nash equilibria. Web1 de mar. de 2007 · Becker and Damianov (2006) proved the existence of symmetric mixed strategy equilibria by using the fixed point theorem of Fan-Glicksberg. In this paper, we utilize the unity partition theorem and a fixed point theorem due to Górniewicz (1975) to guarantee the existence of pure-strategy Nash equilibrium in non-cooperative games. 2. daily dumbell workouts
