Description:This 1987 book offers a critique of the liberal theory of the state, focusing on a detailed study of cooperation in the absence of the state and of other kinds of coercion. The discussion includes an analysis of collective action and of the Prisoners' Dilemma supergame. It is a revised and expanded edition of the author's classic work of rational choice theory Anarchy and Cooperation, originally published with John Wiley in 1976. The analysis has been recast and developed here to make it more accessible to non-mathematical readers and to provide a more comprehensive and self-contained treatment of the theory of collective action. The book will be of interest to a range of readers in political and social philosophy and in economics.
