The critical mass in collective action

the long version

"People who have a common interest in a collective good do not necessarily find it easy to act collectively in pursuit of that interest. There is usually some mismatch between individual and group interests. There may be an efficacy problem, when no individual is able to provide enough common benefit to make acting worthwhile, or a free-rider problem, when most or all individuals hope that someone else will provide the good. Any attempt to overcome these problems through coordination and collaboration entails costs and problems of its own." "This book is a formal mathematical analysis of some of the processes whereby groups solve the problems of collective action. The authors break new ground in showing that the problem of collective action requires a model of group process and group heterogeneity, and cannot be deduced from simple models of individual behavior. They emphasize the role of small subgroups of especially motivated and resourceful individuals who form the "critical mass" that sets collective action in motion." "The book will be read with special interest by sociologists, social psychologists, economists, and political scientists. It will also be of concern to those in industrial relations, communications research, and other fields who are working on issues in collective action and rational choice."--BOOK JACKET.
