Conceptual Index

Approaches to the study of international relations employ a wide variety of concepts and indicators. The interrelationships among these concepts often are specified in conceptual schemes, models, or theories. This supplementary issue of World Politics presents several approaches to international relations theory which utilize familiar concepts, such as decision-making, crisis, and interdependence, and also concepts (frequently borrowed from other disciplines) that are less familiar, e.g., entrepreneurial and consumer roles, free riders, and externalities. The diversity of approaches and the variety of models specified by the contributors led the co-editors to commission an index focusing on concepts and the variables used to tap the concepts (indicators) rather than a more traditional listing of names, places, and events.
