Extensive Form Games

Abstract

The most profound reason why the Nash equilibrium concept has to be refined lies in the fact that a Nash equilibrium of an extensive form game may prescribe irrational behavior at unreached parts of the game tree. Until now, however, we have Mainly studied games in normal form. This comprehensive study yielded a deeper insight into the relations between various refinements of the Nash equilibrium concept. Our goal in this chapter is to investigate to what extend this study has yielded results which are also relevant for extensive form games. It will turn out that the insights we obtained are valuable, but that many results we proved for normal form games cannot be generalized to extensive form games.
