[...]... 1 Introduction This chapter is divided into three sections In the first section the different kinds of cooperative games are discussed A verbal description of the contents of this book is given in the second section and, finally, Section 1.3 describes one of the main goals of this book and comments on some related aspects 1.1 Cooperative Games This book is devoted to a study of the basic properties of. .. characterization of the set of all games with a nonempty core (the balanced games) ; (2) a characterization of market games as totally balanced games; and (3) an axiomatization of the core on the class of balanced games Various bargaining sets are studied in Chapter 4 We provide an existence theorem for bargaining sets which can be generalized to NTU games Furthermore, it is proved that the Aumann-Davis-Maschler... Remarks The analysis of solutions of cooperative games emphasizes the axiomatic approaches which do not rely on interpersonal comparisons of utility Moreover, we comment on the Nash program 1.3.1 Axiomatizations One of our main goals is to supply uniform and coherent axiomatizations for the main solutions of cooperative games Indeed, this book is the first to include axiomatizations of the core, the prekernel,... They occur in many applications of game theory to political science The last section is devoted to a detailed discussion of properties of solutions of coalitional games We systematically list all the main axioms for solutions, consider their plausibility, and show that they are satisfied by the core, which is an important solution for cooperative games 2.1 Coalitional Games Let U be a nonempty set of. .. set of subsets of N satisfying: N ∈ W ∅ ∈ W / S ⊆ T ⊆ N and S ∈ W ⇒ T ∈ W (2.2.1) (2.2.2) (2.2.3) The collection W of coalitions is the set of winning coalitions Property 2.2.3 is the monotonicity property of simple games Intuitively, a simple game g = (N, W) represents a committee: The coalition N is the set of members of the committee and W is the set of coalitions that fully control the decision of. .. market games, cost allocation games, and simple games Games in the foregoing families frequently occur in applications Finally, we systematically list the properties of the core These properties, 1.2 Outline of the Book 3 suitably modified, serve later, in different combinations, as axioms for the core itself, the prekernel, the prenucleolus, and the Shapley value Chapter 3 is devoted to the core The main... Families of Games 15 Example 2.2.4 (Airport games) Consider an airport with one runway Suppose that there are m different types of aircrafts and that ck , 1 ≤ k ≤ m, is the cost of building a runway to accommodate an aircraft of type k Let Nk be the set of aircraft landings of type k in m a given time period, and let N = k=1 Nk Thus, the “players” (the members of N ) are landings of aircrafts The cost... considered in Section 2.2 The first class of games that is discussed is that of market games They model an exchange economy with money Then we proceed to describe cost allocation games We give in detail three examples: a water supply problem, airport games, and minimum cost spanning tree games Finally, we examine the basic properties of simple games These games describe parliaments, town councils, ad hoc... prove that the kernel of a convex game coincides with its nucleolus Chapter 6 mainly focuses on: (1) Sobolev’s axiomatization of the prenucleolus; (2) an investigation of the nucleolus of strong weighted majority games which shows, in particular, that the nucleolus of a strong weighted majority game is a representation of the game; and (3) definition and verification of the basic properties of the modiclus;... Owen’s value of games with a priori unions and his formula relating the Shapley value of a game to the multilinear extension of the game Chapter 9 is devoted to continuity properties of solutions All our solutions are upper hemicontinuous and closed-valued The core and the nucleolus are actually continuous The continuity of the Shapley value is obvious In Chapter 10 dynamic systems for the prekernel . of this volume.
