How do people behave in different traffic situations? Are there general laws for mathematical modelling of decision dynamics? The answers, given at the first international workshop on "Human Behaviour in Traffic Networks", are presented in this volume. In 13 articles, well-known experts report about their current work on experiments and modelling in this area. The topics range from psychological behaviour in traffic situations, traffic simulations of various aspects and market analysis to experiments with human participants used in experimental economics. The articles filled with many illustrations are aimed at interested students as well as experts in this field.

"Modeling Bounded Rational Behavior in Experimental Games and Markets" was the general theme of the Fourth Conference on Experimental Economics, held from September 21 to 25, 1986 at the Zentrum fUr Interdisziplinare Forschung in Bielefeld, Germany. This volume contains the papers presented at this conference in a revised and condensed form. The discussed topics concern experimental economics in general, unilateral and bilateral decisions, auctions and markets, and the problem of coalition formation. A selective bibliograpghy of the participants' work in the field of experimental economics is added. On behalf of the Conference Board and of the Gesellschaft fur Experimentelle Wirtschaftsforschung we express thanks to the Zentrum fur Interdiszipl inare Forschung for organizing and financing the conference. We owe thanks also to an anonymous donor for additional financial support. We thank Ulrich Vossebein and Sigrid . Manthey for their help in preparing the conference and this publication.

There are two main approaches towards the phenotypic analysis of frequency dependent natural selection. First, there is the approach of evolutionary game theory, which was introduced in 1973 by John Maynard Smith and George R. Price. In this theory, the dynamical process of natural selection is not modeled explicitly. Instead, the selective forces acting within a population are represented by a fitness function, which is then analysed according to the concept of an evolutionarily stable strategy or ESS. Later on, the static approach of evolutionary game theory has been complemented by a dynamic stability analysis of the replicator equations. Introduced by Peter D. Taylor and Leo B. Jonker in 1978, these equations specify a class of dynamical systems, which provide a simple dynamic description of a selection process. Usually, the investigation of the replicator dynamics centers around a stability analysis of their stationary solutions. Although evolutionary stability and dynamic stability both intend to characterize the long-term outcome of frequency dependent selection, these concepts differ considerably in the 'philosophies' on which they are based. It is therefore not too surprising that they often lead to quite different evolutionary predictions (see, e. g. , Weissing 1983). The present paper intends to illustrate the incongruities between the two approaches towards a phenotypic theory of natural selection. A detailed game theoretical and dynamical analysis is given for a generic class of evolutionary normal form games.

The four volumes Game Equilibrium Models contain the results of an interdisciplinary research group on non-cooperative game theory. Volume II is mainly of interest for economists.

The four volumes of Game Equilibrium Models present applications of non-cooperative game theory. Problems of strategic interaction arising in biology, economics, political science and the social sciences in general are treated in 42 papers on a wide variety of subjects. Internationally known authors with backgrounds in various disciplines have contributed original research. The reader finds innovative modelling combined with advanced methods of analysis. The four volumes are the outcome of a research year at the Center for Interdisciplinary Studies of the University of Bielefeld. The close interaction of an international interdisciplinary group of researchers has produced an unusual collection of remarkable results of great interest for everybody who wants to be informed on the scope, potential, and future direction of work in applied game theory. Volume III Strategic Bargaining contains ten papers on game equilibrium models of bargaining. All these contributions look at bargaining situations as non-cooperative games. General models of two-person and n-person bargaining are explored.

Volume IV Social and Political Interaction contains game equilibrium models focussing on social and political interaction within communities or states or between states, i.e. national and international social and political interaction. Specific aspects of those interactions are modelled as non-cooperative games and their equilibria are analysed.

This book is a collection of essays in honor of John C. Harsanyi. Originally, we hoped that it would be ready in the year of his 70th birthday, but we did not quite succeed. It sometimes takes longer than anticipated to do things as well as one wants. I think that John Harsanyi will understand this. It is my desire to express our thanks to all those who helped to make the book possible, especially to the publishing house, the Springer Verlag. I am grateful to Hildegard Grober who assisted us in the organizational tasks connected to our editorial effort. I am deeply indebted to Horace W. Brock. His active support was extremely valuable. The results of my editorial efforts should partly be attributed to him. Reinhard Selten Table of Contents Introduction 1 I.

The papers collected in this volume relate to game theory. They aim at the elaboration and discussion of basic con­ cepts, at the analysis of specific applied models and at the evaluation of experimental evidence. A game is a mathematical model of a situation where several actors with different goals are engaged in strategic inter­ action. Game theory explores the nature and the consequence. s of rational behavior in games. With respect to several papers in this volume, it seems to be appropriate to comment on later developments. A list of some important references is given at the end of the intro­ duction. References already included in the collected pa­ pers are not repeated here. In casual conversation colleagues sometimes observe that the author on the one hand goes to extremes in the elabora­ tion of the consequences of Bayesian rationality and on the other hand strongly emphasizes the limited rationality of actual decision behavior. This seeming discrepancy is also expressed in the collection presented here. The author thinks that a sharp distinction should be made between nor­ ~ative and descriptive game theory. This position of "methodological dualism" has been expressed in a comment to Aumann's paper "What is game theory trying to accomplish?" (Aumann, 1985, Selten 1985) Normative game theory has the important task to explore the nature and the consequences of idealized full rationality in strategic interaction. This requires a thorough discuss­ ion of first principles. Empirical arguments are irrelevant here.
