Selecting Equilibria using Best-Response Dynamics

نویسنده

  • Vincent Boucher
چکیده

I propose a simple simulation procedure for large games with multiple equilibria. The simulation procedure is based on a best-response dynamic. The implied equilibrium selection mechanism is intuitive: more stable equilibria are selected with higher probability. JEL Codes: C62, C72, C73

Statics and Dynamics of Selfish Interactions in Distributed Service Systems

We study a class of games which models the competition among agents to access some service provided by distributed service units and which exhibits congestion and frustration phenomena when service units have limited capacity. We propose a technique, based on the cavity method of statistical physics, to characterize the full spectrum of Nash equilibria of the game. The analysis reveals a large ...

Evolutionary network games: equilibria from imitation and best-response dynamics

We consider games of strategic substitutes and strategic complements on networks. We introduce two different evolutionary dynamics in order to refine their multiplicity of equilibria, and we analyse the system through a mean field approach. We find that for the best-shot game, taken as a model for substitutes, a replicator-like dynamics does not lead to Nash equilibria, whereas it leads to uniq...

Complexity of Game Dynamics

Complexity of Game Dynamics by Alexander Fabrikant Doctor of Philosophy in Computer Science University of California at Berkeley Professor Christos H. Papadimitriou, Chair What happens when independent agents interact based on their selfish interests? Game theory’s earliest and most natural simple model of such interaction is the best-response Nash dynamics, the process of agents making unilate...

Basins of Attraction and Equilibrium Selection Under Different Learning Rules

A deterministic learning model applied to a game with multiple equilibria produces distinct basins of attraction for those equilibria. In symmetric two-by-two games, basins of attraction are invariant to a wide range of learning rules including best response dynamics, replicator dynamics, and fictitious play. In this paper, we construct a class of three-by-three symmetric games for which the ov...

Local contraction-stability and uniqueness

This paper investigates the relationship between uniqueness of Nash equilibria and local stability with respect to the best-response dynamics in the cases of sum-aggregative and symmetric games. If strategies are equilibrium complements, local stability and uniqueness are the same formal properties of the game. With equilibrium substitutes, local stability is stronger than uniqueness. If player...
