After Hegemony (full title: After Hegemony: Cooperation and Discord in the World Political Economy) is a book by Robert Keohane first published in 1984. It is a leading text in the liberal institutionalist international relations scholarship. The book challenges neorealist claims that meaningful international cooperation is not possible, as well as hegemonic stability theory claims that international cooperation is only possible under hegemony. The book applies insights from new institutional economics to international relations. The book shows how realist assumptions about actors and the international system can logically lead to the conclusion that meaningful cooperation is possible. Source: Wikipedia (en)
