Summary and Keywords
The study of international organizations (IOs) has been described as lacking theoretical depth. However, the field actually has a more solid theoretical foundation than some of its critics allege. Moreover, the variety of approaches has entailed multifaceted knowledge of the internal workings as well as the global effects of IOs. Three theoretical traditions have emerged, dealing with institutions, organization, and governance. Institutional analysis has a central position in political science. In the study of domestic institutions, three major schools—rational choice institutionalism, historical institutionalism, and sociological institutionalism—have emerged. Organization theory represents a change of focus from the ideational structures studied by institutionalists to more material and human structures. Whereas both institutional and organizational approaches were originally formulated for domestic structures, institutionalists have been more receptive to exploring domestic-international analogies and contrasts. Even if both institutional and organization theories pay attention to process— institutionalizing rules and practices as well as organizing collective entities are long-term processes— IO studies inspired by these approaches tend to focus on relatively stable structures, asking questions concerning the establishment, persistence or change, and impact of international institutions and organizations. A third, more recent perspective focuses on continuous processes of governance, involving international organizations as well as other types of actors.
