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.

In Role Compatibility as Socialization, Dorothée Vandamme examines Pakistan’s socialization process in terms of role compatibility in the 2008-2018 period. Adopting an Interpretative phenomenological analysis (IPA) method of analysis, Vandamme builds on role theory to develop a theory of socialization as role compatibility to explain the dynamics of Pakistan’s (dys)functioning position and its status-seeking process as a fully functioning member of the international system. Specifically, she focuses on how Pakistani civilian and military leaders define their country’s positioning towards India, the United States and China. In doing so, she traces the link between domestic role contestation at the country’s inception and the resulting domination of the military’s conception of their country, state identity, how it projects itself externally and how it is received by others. Departing from strictly structural or agent-oriented explanations, Vandamme expertly demonstrates Pakistan’s perceived role compatibility with significant others and underlines the causality between state identity, foreign policy behavior and socialization. Role Compatibility as Socialization will be of interest to graduate students and researchers who work on and with role theory and socialization theory, and for those with a research interest on South Asia.

In this monograph, noncooperative games are studied. Since in a noncooperative game binding agreements are not possible, the solution of such a game has to be self enforcing, i. e. a Nash equilibrium (NASH [1950,1951J). In general, however, a game may possess many equilibria and so the problem arises which one of these should be chosen as the solution. It was first pointed out explicitly in SELTEN [1965J that I not all Nash equilibria of an extensive form game are qualified to be selected as the solution, since an equilibrium may prescribe irrational behavior at unreached parts of the game tree. Moreover, also for normal form games not all Nash equilibria are eligible, since an equilibrium need not be robust with respect to slight perturba tions in the data of the game. These observations lead to the conclusion that the Nash equilibrium concept has to be refined in order to obtain sensible solutions for every game. In the monograph, various refinements of the Nash equilibrium concept are studied. Some of these have been proposed in the literature, but others are presented here for the first time. The objective is to study the relations between these refine ments;to derive characterizations and to discuss the underlying assumptions. The greater part of the monograph (the chapters 2-5) is devoted to the study of normal form games. Extensive form games are considered in chapter 6.
