Contributions to the Theory of SolutionConcepts for Strategic GamesInauguraldissertationzur Erlangung des akademischen Gradeseines Doktors der Wirtschaftswissenschaftender Universität MannheimAlexander Zimpervorgelegt im Sommersemester 2003Referent: Prof. Martin Hellwig, Ph.D.Korreferent Prof. Itzhak Gilboa, Ph.D.Dekan: Prof. Dr. Christoph BuchheimTag der mündlichen Prüfung: 21. Juli 2003 Acknowledgments My thesis consists of 3 ¼ self-contained papers of which older versions had been circulating around for some time. ‘Circulating around’ means: I bothered some people to read them and surprisingly many took their time to give me valuable comments. I would like to thank the following people for their contributions: Tilman Börgers, Eddie Dekel, Christian Ewerhart, Itzhak Gilboa, Bertrand Koebel, and Ulrich Schmidt. As a member of the Mannheimer Graduiertenkolleg ''Allokation auf Finanz-und Gütermärkten'' I received financial support from the Deutsche Forschungsgemeinschaft. Furthermore, while I stayed three months at the University College of London, a Marie-Curie-scholarship by the European Union payed for my rent. Thanks to these institutions. Special thanks to my supervisor, Martin Hellwig, for his guidance and patience. iiiContents1 Introduction 12 Uniqueness Of Rationalizable Solutions 162.1 Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 162.2 De…nitions . . . . . . . . . . . . . . . . . . .
