New Institutionalism is currently one of the most prominent approaches in political science. In this innovative collection, top scholars in the field offer substantial theoretical and analytical contributions to new institutionalist scholarship, engaging in debates about structure and agency, state-society relations, institutional creation and change, preference formation, and the complicated web of relationships between institutions, culture, ideas, identity, rationality, and interests. From an analytical point of view, the contributors examine how the state and political institutions shape a variety of political phenomena and outcomes, namely, nationalism, democratic transition, party aggregation, policy networks, war and peace, international recognition, sovereignty, and selected public policies. They offer thorough theoretical reflections on the relationship between institutions and society as well as on the role of institutions in political analysis. Featuring discussions of comparative politics, public policy, and international relations, as well as the institutionalist traditions of English and French Canadian political science, this collection from editor Andr Lecours is a comprehensive examination of the subject, making it a crucial addition to any political scientist's library.
