Twenty-four scholars from the U.S., Canada, and Europe contribute 13 chapters which advance the integration of social scientific knowledge about change and innovation within and across different levels of organizations and across a range of disciplines. The text focuses on key constituents of organizations-individual members, groups, organizational systems, and organizational and institutional fields-and explores the most popular current theories-including evolutionary perspectives, institutional theories, life-cycle models, and models of planned change-and emerging theoretical perspectives, such as coevolutionary theory, dialectical theory, and complexity theory. For researchers, teachers, and students in organizational studies.
