Book on Rationality in Extensive Form Games
Between 1998 and 2001 I have been writing my book Rationality in Extensive Form Games. The book has appeared in 2001, and has been published by Kluwer Academic Publishers (Boston/Dordrecht/London). It is part of the Theory and Decision Library, Series C: Game Theory, Mathematical Programming and Operations Research.

Geir Asheim has written a review on this book, which has appeared in the Journal of Economics.
In this book, I discuss various concepts of rationality in dynamic games. Examples of such concepts are: backward induction, subgame perfect equilibrium, quasi-perfect equilibrium, sequential equilibrium, various notions of forward induction, stable sets of equilibria, weak sequential rationalizability, and extensive form rationalizability. For each of these concepts, I discuss its motivation, often by means of examples, provide a precise definition, investigate its properties, and analyze its relationship with other rationality concepts. For almost all results I provide a complete proof.
This book has been written for PhD-students and researchers who want to learn about the problem of rational behavior in dynamic games. Researchers within the area may also use the book to deepen their knowledge about some parts of the field. Parts of this book can be used for a PhD-course in game theory.
