Over the past three decades, Meyer, Jepperson, and colleagues have contributed to the development of one of the leading approaches in social theory, by analyzing the cultural frameworks that have shaped modern organizations, states, and identities. Bringing together key articles and new reflections, this volume collects the essential theoretical ideas of 'sociological neoinstitutionalism.' It clarifies the core ideas and situates them within social theory writ large. Among other topics, the authors discuss the changing nature of the "actors" that have operated within contemporary social structure. The book concludes with the evolving frameworks that have structured social activity in the post-World War II period of 'embedded liberalism,' in the more recent neoliberal period, and in an emergent post-liberal period that appears to be a radical departure.
