Realism and constructivism are often viewed as competing paradigms for understanding International Relations, but a number of scholars are now arguing that the two are compatible. This volume, from one of the leading proponents of realist constructivism, combines both exposition and critique of realist constructivist approaches with a series of international case studies to show what realist constructivist research can look like in practice.

This comprehensively revised and updated edition offers an introduction to international organizations (IO) theory in the field of IR. It looks at the different ways in which IOs are studied and then applies these different modes to a variety of specific case studies. The book is written as a primer for students studying global governance and IR theory. It highlights analytic tools available to understand what IOs are designed to do, how they work, what effects they have, and how to design them better. It goes beyond simple questions of whether IOs matter, and looks at the ways in which the different analytical tools developed within the rubric of IO theory are useful for answering different questions about the role of IOs in international politics.

Countering the growing divide between positivists who embrace quantitative, numerical approaches and post-positivist scholars who favor qualitative, interpretive approaches, J. Samuel Barkin and Laura Sjoberg argue that both methods are more widely adaptable than is commonly assumed by either camp. In Interpretive Quantification, ten highly regarded scholars in the field of International Relations apply quantitative methods and formal models to specific constructivist and critical research questions. In this way, each chapter serves not only as evidence that methods can productively be applied across paradigms, but also as a guide as to how this may be done. In sum, the contributors make a compelling case that when researchers cordon off particular methods for merely ideological reasons, they circumscribe their own paradigms and hinder their own research agenda.

Sovereignty is the subject of many debates in international relations. Is it the source of state authority or a description of it? What is its history? Is it strengthening or weakening? Is it changing, and how? This book addresses these questions, but focuses on one less frequently addressed: what makes state sovereignty possible? The Sovereignty Cartel argues that sovereignty is built on state collusion - states work together to privilege sovereignty in global politics, because they benefit from sovereignty's exclusivity. This book explores this collusive behavior in international law, international political economy, international security, and migration and citizenship. In all these areas, states accord rights to other states, regardless of relative power, relative wealth, or relative position. Sovereignty, as a (changing) set of property rights for which states collude, accounts for this behavior not as anomaly (as other theories would) but instead as fundamental to the sovereign states system.

Realism and constructivism, two key contemporary theoretical approaches to the study of international relations, are commonly taught as mutually exclusive ways of understanding the subject. Realist Constructivism explores the common ground between the two, and demonstrates that, rather than being in simple opposition, they have areas of both tension and overlap. There is indeed space to engage in a realist constructivism. But at the same time, there are important distinctions between them, and there remains a need for a constructivism that is not realist, and a realism that is not constructivist. Samuel Barkin argues more broadly for a different way of thinking about theories of international relations, that focuses on the corresponding elements within various approaches rather than on a small set of mutually exclusive paradigms. Realist Constructivism provides an interesting new way for scholars and students to think about international relations theory.

This book moves scholarly debates beyond the old question of whether or not international institutions matter in order to examine how they matter, even in a world of power politics. Power politics and international institutions are often studied as two separate domains, but this is in need of rethinking because today most states strategically use institutions to further their interests. Anders Wivel, T.V. Paul, and the international group of contributing authors update our understanding of how institutions are viewed among the major theoretical paradigms in international relations, and they seek to bridge the divides. Empirical chapters examine specific institutions in practice, including the United Nations, International Atomic Energy Agency, and the European Union. The book also points the way to future research. International Institutions and Power Politics provides insights for both international relations theory and practical matters of foreign affairs, and it will be essential reading for all international relations scholars and advanced students.
