A review of books by John Bonner, Politics, Economics and Welfare (Brighton: Wheatsheaf Books, 1986); Jon Elster & Aanund Hylland [Eds], Foundations of Social Choice Theory (Cambridge & New York: Cambridge U Press, 1986); & Michale Laver, Social Choice and Public Policy (Oxford & New York: Basil Blackwell, 1986 [see listings in IRPS No. 43]). Bonner's work introduces the main elements of social choice theory to undergraduates, & presents the concepts of social welfare, utility, rationality, interpersonal comparisons, &, especially, the issue of deriving aggregate or collective welfare functions. Laver's work is also directed toward undergraduates, but its somewhat novel approach should give it a wider audience. The problem of collective action is at the core of the text. A framework for a general comparative discussion of policy outcomes in different systems is developed. The Elster & Hylland work is a collection of essays addressing substantive issues in social choice theory. F. Rasmussen

Theory of social choice mechanisms is a comparatively new theory. The first results were obtained as early as the beginning of the seventies. The book contains the most important results of the theory. In two main topics the book describes what mechanisms allow equilibrium solutions at any agents` preference profiles, and what outcomes can be implemented. The answer depends on the equilibrium concept. Furthermore the four equilibrium concepts Nash equilibrium, strong Nash equilibrium, equilibrium in dominant strategies, and the core were described in detail

In this paper, we consider relationships between the collective preference and the non-cooperative game-theoretic approaches to positive political theory. In particular, we show that an apparently decisive difference between the two approaches - that in sufficiently complex environments (e.g. high dimensional choice spaces) direct preference aggregation models are incapable of generating any prediction at all, whereas non-cooperative game-theoretic models almost always generate predictions - is indeed only an apparent difference. More generally, we argue that there is a fundamental tension when modeling collective decisions between insuring existence of well-defined predictions, a criterion of minimal democracy and general applicability to complex environments: while any two of the three are compatible under either approach, neither collective preference nor non-cooperative game theory can support models that simultaneously satisfy all three desiderata.

Since World War II the subject of social choice has grown in many and surprising ways. The impossibility theorems have suggested many directions: mathematical characterisations of voting structures satisfying various sets of conditions, the consequences of restricting choice to certain domaines, the relation to competitive equilibrium and the core, and trade-offs among the partial satisfactions of some conditions. The links with classical and modern theories of justice and, in particular, the competing ideas of rights and utilitarianism have shown the power of formal social choice analysis in illuminating the most basic philosophical arguments about the good social life. Finally, the ideals of the just society meet with the play of self interest; social choice mechanisms can lend themselves to manipulation, and the analysis of conditions under which given ideals can be realised under self interest is a political parallel to the welfare economics of the market. The contributors to these volumes focus on these issues at the forefront of current research.

Many philosophers have regarded social choice theory as a technical discipline of limited relevance to substantive questions in moral & political philosophy. It is argued here, however, that it is concerned with questions of central philosophical importance, since it examines the consistency of various beliefs we may have about the desirable characteristics of philosophical theories about the good for society. Kenneth Arrow (Social Choice and Individual Values [see SA 13:5/64B6797]) showed that some apparently innocuous beliefs are inconsistent, & much of the subsequent literature has been concerned with finding ways out of the inconsistency. One fruitful way of doing so is to relax the requirement that theories be applicable to all conceivable combinations of individual preferences. Another is to accept the moral relevance of many aspects of society other than the welfare of individuals. Some of the literature has focused on rights, & has illuminated our understanding of the risk that the rights of different individuals may conflict. Social choice theory has been increasingly integrated into game theory. Recent developments in the field are noted, & suggestions offered regarding which topics will prove to be of philosophical significance in the future. Modified AA
