Starting from the traditional representations of the firm, this book discusses a variety of other industry organization models, looking not only at companies but also at groups and networks. It also discusses how industry organization impacts on our communities of people. Hence, the reading of industrial dynamics is always complemented with a discussion on policy implications and possible prescriptions. Emphasis is placed on the pluralism of theories, on links with current events, and on economic history. The book is addressed to students of economics and management but also - including the introductory chapters containing basic tools for economic analysis - to students of law, political and social studies, engineering, and the natural sciences.
