Large organizations, particularly corporations, possess considerable resources, and with that comes considerable power, often extending beyond a single community or nation-state. Networks among large corporations enhance that power to the point that they exert a major impact on national and multinational economies and policies, influencing decision-making to achieve their own goals. Networks of Power applies interorganizational analysis to the study of power in three main areas: national policy domains, community influence structures, and national corporate structures. The main body of the text is comprised of original research by the leading authorities in the field and covers such areas as national policy decisions in health and energy, corporate structure, innovative theoretical and methodological approaches, and a critical review of network analysis of interorganizational relations and power. Also presented is an agenda for future research.
