Waldman's book is an extension of the work of George Homans, Social Behaviour: Its Elementary Forms and of Peter M. Blau, Exchange and Power in Social Life. The first chapters summarize the basic propositions of exchange theory as proposed by Homans, and add some exposition due to Blau. The remaining chapters are discussions of such topics as legitimacy, political culture, and conflict resolution in terms of the exchange model.
