Neorealism or structural realism is a theory of international relations that emphasizes the role of power politics in international relations, sees competition and conflict as enduring features and sees limited potential for cooperation. The anarchic state of the international system means that states cannot be certain of other states' intentions and their security, thus prompting them to engage in power politics.
Hegemony is the political, economic, and military predominance of one state over other states. In Ancient Greece, hegemony denoted the politico-military dominance of the hegemon city-state over other city-states. In the 19th century, hegemony denoted the "social or cultural predominance or ascendancy; predominance by one group within a society or milieu" and "a group or regime which exerts undue influence within a society".
International relations (IR), international studies (IS) or international affairs (IA) is the scientific study of interactions between sovereign states. It examines all activities between states—such as war, diplomacy, trade, and foreign policy—as well as relations with and among other international actors, such as intergovernmental organisations (IGOs), international nongovernmental organisations (INGOs), international legal bodies, and multinational corporations (MNCs).
In international relations, multilateralism refers to an alliance of multiple countries pursuing a common goal.
Hegemonic stability theory (HST) is a theory of international relations, rooted in research from the fields of political science, economics, and history. HST indicates that the international system is more likely to remain stable when a single state is the dominant world power, or hegemon. Thus, the end of hegemony diminishes the stability of the international system. As evidence for the stability of hegemony, proponents of HST frequently point to the Pax Britannica and Pax Americana, as well as the instability prior to World War I and the instability of the interwar period.
Regime theory is a theory within international relations derived from the liberal tradition that argues that international institutions or regimes affect the behavior of states or other international actors. It assumes that cooperation is possible in the anarchic system of states, as regimes are, by definition, instances of international cooperation.
Stephen David Krasner is an American academic and former diplomat. Krasner has been a professor of international relations at Stanford University since 1981, and served as the Director of Policy Planning from 2005 to April 2007 while on leave from Stanford.
Robert Owen Keohane is an American academic working within the fields of International Relations and International Political Economy. Following the publication of his influential book After Hegemony (1984), he has become widely associated with the theory of neoliberal institutionalism in international relations, as well as transnational relations and world politics in international relations in the 1970s.
An international regime is the set of principles, norms, rules and procedures that international actors converge around. Sometimes, when formally organized, it can transform into an intergovernmental organization.
Polarity in international relations is any of the various ways in which power is distributed within the international system. It describes the nature of the international system at any given period of time. One generally distinguishes three types of systems: unipolarity, bipolarity, and multipolarity for three or more centers of power. The type of system is completely dependent on the distribution of power and influence of states in a region or globally.
New institutional economics (NIE) is an economic perspective that attempts to extend economics by focusing on the institutions that underlie economic activity and with analysis beyond earlier institutional economics and neoclassical economics. Unlike neoclassical economics, it also considers the role of culture and classical political economy in economic development.
Reflectivism is a broad umbrella label, used primarily in International Relations theory, for a range of theoretical approaches which oppose rational-choice accounts of social phenomena and, perhaps, positivism more generally. The label was popularised by Robert Keohane in his presidential address to the International Studies Association in 1988. The address was entitled "International Institutions: Two Approaches", and contrasted two broad approaches to the study of international institutions. One was "rationalism", the other what Keohane referred to as "reflectivism". Rationalists — including realists, neo-realists, liberals, neo-liberals, and scholars using game-theoretic or expected-utility models — are theorists who adopt the broad theoretical and ontological commitments of rational-choice theory.
Robert Gilpin was an American political scientist. He was Professor of Politics and International Affairs at the Woodrow Wilson School of Public and International Affairs at Princeton University where he held the Eisenhower professorship.
In international relations theory, anarchy is the idea that the world lacks any supreme authority or sovereign. In an anarchic state, there is no hierarchically superior, coercive power that can resolve disputes, enforce law, or order the system of international politics. In international relations, anarchy is widely accepted as the starting point for international relations theory.
The English School of international relations theory maintains that there is a 'society of states' at the international level, despite the condition of anarchy. The English school stands for the conviction that ideas, rather than simply material capabilities, shape the conduct of international politics, and therefore deserve analysis and critique. In this sense it is similar to constructivism, though the English School has its roots more in world history, international law and political theory, and is more open to normative approaches than is generally the case with constructivism.
Complex interdependence in international relations and international political economy is a concept put forth by Robert Keohane and Joseph Nye in the 1970s to describe the emerging nature of the global political economy. The concept entails that relations between states are becoming increasingly deep and complex. These increasingly complex webs of economic interdependence undermine state power and elevate the influence of transnational non-state actors. These complex relationships can be explored through both the liberal and realism lenses and can later explain the debate of power from complex interdependence.
Liberal institutionalism is a theory of international relations that holds that international cooperation between states is feasible and sustainable, and that such cooperation can reduce conflict and competition. Neoliberalism is a revised version of liberalism. Alongside neorealism, liberal institutionalism is one of the two most influential contemporary approaches to international relations.
Liberalism is a school of thought within international relations theory which revolves around three interrelated principles:
Lisa Martin is an American political scientist. She is a professor of political science at the University of Wisconsin, Madison. She studies political institutions in international relations, including economic sanctions and cooperation between states. Martin was the first female editor of International Organization, where she also currently serves as a senior advisor to the journal's editorial board. In 2021, she was elected as president of the American Political Science Association for 2022-2023.
Rational choice is a prominent framework in International Relations scholarship. Rational choice is not a substantive theory of international politics, but rather a methodological approach that focuses on certain types of social explanation for phenomena. In that sense, it is similar to Constructivism, and differs from Liberalism and Realism, which are substantive theories of world politics. Rationalist analyses have been used to substantiate realist theories, as well as liberal theories of international relations.
