Prospect theory is one of the most influential behavioral theories in the international relations (IR) field, particularly among scholars of security studies, political psychology, and foreign policy analysis. Developed by Israeli psychologists Daniel Kahneman and Amos Tversky, prospect theory provides key insights into decision making under conditions of risk and uncertainty. For example, most individuals are risk averse to secure gains, but risk acceptant to avoid losses (loss aversion). In addition, most people value items they already posses more than they value items they want to acquire (endowment effect), and tend to be risk averse if they perceive themselves to be facing gains relative to their reference point (risk propensity). Prospect theory has generated an enormous volume of scholarship in IR, which can be divided into two “generations”. The first generation (1990–1999) sought to establish prospect theory’s plausibility in the “real world” by testing hypotheses derived from it against subjective expected-utility theory or rational choice models of foreign policy decision making. The second generation (2000–present) began to incorporate concepts associated with prospect theory and related experimental literature on group risk taking into existing mid-level theories of IR and foreign policy behavior. Two substantive areas covered by scholars during this period are coercive diplomacy and great power intervention in the periphery as they relate to loss aversion. Both generations of prospect theory literature suffer from conceptual and methodological difficulties, mainly around the issues of reference point selection, framing, and preference reversal outside laboratory settings.
Psychology plays a key role in the success of strategy and is therefore important to the study of international security. There are four general approaches to the psychology of strategy. The first focuses on personality, and more specifically on individual differences, cognition, and the use of evolutionary psychology and neuroscience to investigate human nature. The second approach draws on deterrence theory, which considers how an actor can keep a target from doing something it would otherwise do. A political psychological perspective on deterrence consists of three elements. First, psychological approaches to deterrence reject stimulus–response models and instead lay emphasis on understanding cognition and emotion. Second, deterrence is a policy rather than a philosophy. Third, whereas normative theories explain how one ought to behave (and thus cannot be disconfirmed by evidence), psychological theories change in response to new evidence, such as with the development of prospect theory. The third aspect of strategic interaction involves learning and intelligence assessments. Based on this approach, how people learn, what they are likely to learn, and the problems of assessing the intentions and capabilities of others are central to strategy. The fourth and final approach is concerned with the strategy of group conflict, which has generated two waves of research: the first analyzed how material inequality or competition for resources gives rise to psychological forces that result in group cooperation and between-group competition, and the second added nonmaterial causes to explain group relations.
Public goods represent a particular challenge in international politics that has been linked to problems as diverse as alliance politics, environmental governance, and global currency systems. In many situations, some form of coordinated collective action is needed to produce public goods. Consequently, provision of public good often serves as a stand-in for theoretical questions related to cooperation in an anarchic system.
Public goods, which have elements of non-rivalness and non-excludability, are often desired by states but can be difficult to produce in the absence of a powerful state willing to provide public goods unilaterally. Non-rivalness refers to the ability of many actors to consume a good. Closely related to the concept of non-rivalness in public goods is the concept of jointness of supply. Jointness of supply means that all parties can enjoy the benefits of consumption with no additional cost required to provide the good to additional individuals.
By contrast, non-excludability implies that once a good has been produced, there are no efficient means of preventing consumption of a good. If both of these conditions are true, then a public good, such as asteroid defense or the elimination of smallpox, could be a benefit to all of humanity once produced. On the other hand, pure public goods are relatively rare. There are variations in which non-rivalness or non-excludability is imperfectly met. Club goods, such as security in alliances, offer viable mechanisms for excluding states from the benefits of a good but may produce goods that are non-rival within the club. Common-pool resources, such as ocean fish populations, are non-excludable but are rival, in that overfishing can reduce fish populations.
Ethnicity, nationalism, and migration are popular topics in many academic disciplines, but research on public opinion in these areas has suffered from a lack of good data, disciplinary fragmentation, and a dearth of studies that engage one another. This is evident in the case of public opinion survey research undertaken in the world’s hotspots of ethnic conflict. As a result, ethnic conflict scholars have had to rely on proxy measures or indirect studies to test “opinion” towards ethnicity and nationalism in the developing world. In the developed world, however, there is more to work with in terms of opinion measurements. A prominent example is the European Union’s “Eurobarometer” surveys, which gauge attachment to and identification with “Europe” and the individual nation. Research on national identity and ethnic conflict has often been the starting point for theories of public opinion regarding immigration. A common finding is that there is a weak connection (if any) between opinion and policy on the immigration issue. Several areas need to be addressed as far as research is concerned. For example, the picture of xenophobic hostility in rich countries must be understood in a context of general changes in word migration patterns, with some emerging economies also experiencing high levels of immigration, and concurrent anti-immigrant public opinion. Two shortcomings of the literature also deserve closer attention: a focus on developing-to-developed country migration; and a lack of analyses that combine push and pull factors, to measure their relative causal weight in terms of bilateral immigration flows.

The term “public” is predominantly used in International Relations (IR), often appearing as an attribute in collocations such as “public goods” or “public opinion.” The study of public spheres can be meaningfully situated within the scope of the emerging field of International Political Sociology (IPS). At the heart of the study of public spheres as an integral part of IPS is the challenge of theorizing the relations between public spheres and an emerging postnational political order. One perennial concern of IPS that can be addressed through the study of public spheres is the relation between empirical and normative inquiry. In addition, the study of public spheres constitutes an interdisciplinary arena that contributes to the process of opening up IR to the theoretical and methodological toolkit of adjacent intellectual fields. In this context, the study of social movements comes to mind, especially when it directly tackles processes of “contentious politics.” An analysis of the way in which the term “public” is used in IR can offer important insights into the social-theoretical presuppositions and implicit concepts of social and international order that go along with it. The study of public spheres is not confined to the study of a set of firmly delineated empirical phenomena, which may or may not be observed. It can also be used to elucidate the oft-neglected problem of how political authority is constituted in terms of both theoretical and empirical inquiry.

Security issues have long been linked to the study of international relations. The crucial issue which scholars and decision makers have sought to understand is how states can avoid being victimized by war while also being prepared for any eventuality of war. Particular attention has been devoted to alliances and armaments as the policy instruments that should have the greatest effect on state war experiences. Scholars have attempted to use balance of power theories to explain the interrelationships between arms, alliances, and international conflict, but the overwhelming lack of empirical support for such theories led the field to look for alternatives. This gave rise to new theorizing that recognized variance in national goals and an enhanced role for domestic politics, which in turn encouraged empirical tests at the nation state or dyadic level of analysis. Drawing from existing theoretical perspectives, more specific formal models and empirical tests were invoked to tackle particular questions about alliances and arms acquisitions. Despite significant advances in individual “islands of theory,” however, integrated explanations of the pursuit and effects of security policies have remained elusive. An important consideration for the future is to develop of theories of security policy that take into account the substitutability and complementarity of varying components. There have been two promising attempts at such integrated theorizing: the first explains the steps to war and the second is based on the assumption that states pursue two composite goods through foreign policy.

The term “race” refers to groups of people who have differences and similarities in biological traits deemed by society to be socially significant, meaning that people treat other people differently because of them. Meanwhile, ethnicity refers to shared cultural practices, perspectives, and distinctions that set apart one group of people from another. Ethnic differences are not inherited; they are learned. When racial or ethnic groups merge in a political movement as a form of establishing a distinct political unit, then such groups can be termed nations that may be seen as representing beliefs in nationalism. Race and ethnicity are linked with nationality particularly in cases involving transnational migration or colonial expansion. Anthropologists and historians, following the modernist understanding of ethnicity, see nations and nationalism as developing with the rise of the modern state system. They culminated in the rise of “nation-states,” in which the presumptive boundaries of the nation coincided with state boundaries. Thus, the notion of ethnicity, like race and nation, developed in the context of European colonial expansion, when mercantilism and capitalism were promoting global movements of populations at the same time that state boundaries were being more clearly and rigidly defined. Theories about the relation between race, ethnicity, and nationality are also linked to more general ideas about the impact of genomics on social life—ideas that often refer to the growing “geneticization” of social life.
Race(ing) International Relations: A Critical Overview of Postcolonial Feminism in International Relations
Geeta Chowdhry and L.H.M. Ling
Postcolonial feminism in international relations (PFIR) is a disciplinary field devoted to the study of world politics as a site of power relations shaped by colonization. PFIR combines postcolonial and feminist insights to explore questions such as how the stratum of elite power intersects with subterranean layers of colonization to produce our contemporary world politics; how these interrelationships between race, gender, sex, and class inform matrices of power in world politics; and how we account for elite and subaltern agency and resistance to the hegemonic sphere of world politics. PFIR is similar to Marxism, constructivism, and postmodernism in that they all posit that the masses underwrite hegemonic rule and, in so doing, ultimately have the means to do away with it. One difference is that PFIR emanates from the position of the subaltern; more specifically, the colonized’s colonized such as women, children, the illiterate, the poor, the landless, and the voiceless. Three major components are involved in PFIR in its analysis of world politics: culture, politics, and material structures. Also, eight common foci emerge in PFIR: intersectionality, representation, and power; materiality; relationality; multiplicity; intersubjectivity; contrapuntality; complicity; and resistance and accountability. PFIR gives rise to two interrelated projects: an empirical inquiry into the construction and exercise of power in daily life, and theory building that reflects this empirical base. A future challenge for PFIR is to elucidate how we can transform, not just alleviate, the hegemonies that persist around the world.

In 1969, the game theorist John Harsanyi wrote an article criticizing the two main postulates of the general theory of social behavior prevalent at the time: the functionalist approach to the explanation of social institutions and the conformist approach to the explanation of individual behavior. According to Harsanyi, functionalist and conformist theories overstated the degree of consensus in societies, could not account for change, and described observed behavior without explaining it. Harsanyi proposed an alternative approach provided by theories based on the concept of rational choice (rational behavior, or rational decision-making). His goal was to develop a hypothetico-deductive theory explaining (and possibly predicting) a large number of empirical facts from a few relatively simple theoretical assumptions or axioms. Among students of international politics, Harsanyi’s approach sparked a controversy about rationalism. However, some critics of rationalism do not distinguish clearly between the interest-based theories Harsanyi criticized and the rational choice methods he advocated, and some even confuse both with neoclassical economics. In order to understand the issues raised in the controversy about rationalism, it is helpful to look at interest-based theories of politics and their relation to neoclassical economics. Game theory has provided a useful framework for the intellectual agenda outlined by Harsanyi, especially in the area of international security.

Political Realism has been described as the “oldest theory” of international politics, as well as the “dominant” one. Central to the realist tradition is the concept of “security.” Realism sees the insecurity of states as the main problem in international relations. It depicts the international system as a realm where “self-help” is the primary motivation; states must provide security for themselves because no other agency or actor can be counted on to do so. However, realists offer different explanations for why security is scarce, emphasizing a range of underlying mechanisms and causal factors such as man’s innate desire for power; conflicts of interest that arise between states possessing different resource endowments, economic systems, and political orders; and the “ordering principle” of international anarchy. They also propose numerous factors that can intensify or ameliorate the basic security problem, such as polarity, shifts in the overall balance of power, the “offense–defense balance,” and domestic politics. Several alternative approaches to international relations have challenged the basic realist account of the security problem, three of which are democratic peace theory, economic liberalism, and social constructivism. Furthermore, realism outlines various strategies that states can pursue in order to make themselves more secure, such as maximizing power, international alliances, arms racing, socialization and innovation, and institutions and diplomacy. Scholars continue to debate the historical roots, conceptual foundations, and predictive accuracy of realism. New avenues of research cover issues such as civil war, ethnic conflict, mass violence, September 11, and the Iraq War.
Truth commissions are temporary institutions that are tasked with investigating patterns of political violence under a prior regime as part of a process of political change. In the past, truth commissions were generally seen as a “second best” alternative in contexts where prosecuting past abuses was deemed unrealistic. Today, they are regarded as important tools for pursuing a wide array of goals, from democratization and reconciliation to human rights protection and individual healing. Early scholarship on the development of truth commissions focused on comparative democratization and on typologies that could be used to predict various transitional justice outcomes. More recently, scholars in the field of international relations have undertaken qualitative and quantitative studies in hopes of understanding what is driving the development of truth commissions. However, opinions differ as to the causes, consequences, and moral implications of truth commissions. Some attribute the proliferation of truth commissions to the growing strength of human rights norms and advocacy, whereas others argue that they merely function to manage the balance of power in transitional contexts, or serve as a basis for advancing values such as justice, democracy, and peace. These debates seem to have only intensified as truth commission scholarship continues to grow. One interesting pattern is that a number of scholars, have questioned the effectiveness of truth commissions in satisfying their own claims to investigate the “truth” about past abuses.

Reciprocity refers to the character of the actions and reactions between two or more actors. This character is commonly one of responding in kind to the actions of another. As such, reciprocity is considered one of the fundamental processes observed by scholars in the study of international relations (IR). In the realm of international politics, the study of reciprocity typically encompasses formal/experimental and empirical research. Some scholars look at ethical dimensions and the propagation of norms such as the Golden Rule, while others undertake empirical analysis of patterns of reciprocity in search of answers to questions about the existence, predictability, and diffusion of reciprocity. As a concept, reciprocity has applications in a range of IR topics such as the basic ingredients of cooperation, the escalation and return of conflict, and the adherence to international law. Within the realm of conflict processes, the iterated Prisoner’s Dilemma (PD) and formal frameworks are often used to represent arms races and similar security concerns. Related to the iterated PD is the work of Robert Axelrod, who demonstrated the robustness of the reciprocal strategy known as tit-for-tat (TFT). One puzzle on reciprocity that deserves consideration in future research is that the expectation of a long time horizon for interaction should stimulate the incentive to cooperate, but long time horizons may also be associated with long pasts. One way to find the answer to this puzzle is to incorporate reciprocity into more general models of international interaction.

After years of communism and central planning, Russia and China embarked on broad transformations from planned to market economy and limited political liberalization reforms. Chinese reforms commenced in 1978, while those in the Soviet Union started in 1991. The two countries took contrasting paths to economic reform, and their experiences during economic transition have been viewed as polar opposites. The reform experiences of Russia and China sparked intense academic debates over a variety of issues surrounding transition from communism to market economy. The primary source of scholarly disagreement is whether the pace, the sequence, or country-specific initial conditions determines the success of economic and political reforms. The debates revolved around questions such as whether there is a relationship between economic processes and political reforms in the transitional states, or whether economic liberalization should pave the way for political liberalization. Two dominant approaches to transition from socialism to capitalism advanced in the literature are “shock therapy” and gradualism; the former was adopted by the Russians and the latter by the Chinese. Several lessons can be learned from the Russian and Chinese transition, such as the impact of structural forces on the leadership’s policy preferences and the importance of tenable development policies to ensure the success of economic reforms. Notwithstanding these lessons, there remain a number of questions that deserve further investigation, mainly in terms of the role of China and Russia in world politics.

The term “international regime” was originally used to describe formal agreements between states, but the concept has since evolved after going through considerable critique and reformulation. A universal agreement on the precise nature or elements of a regime has remained elusive, despite a general consensus on the definition. Nevertheless, the concept of regime offers a unique opportunity to better understand international relationships by underscoring the importance of specific attributes of international, multinational, and nongovernmental groups, sets of behavioral or epistemic practices, and processes of learning. As a heuristic device, regime theory helps to explain the rise of complex interaction between states, organizations, corporations, and other institutions as well as the potential for ideas or behavior to shape the international system. Regime theory has supplemented traditional explanations of international order, including hegemonic stability theory or neorealism, by explaining the emergence of cooperation and organization within what would traditionally be considered anarchical or highly unpredictable conditions. Common approaches to regime theory include realism, neoliberalism, cognitivism, and constructivism. Part of the strength of regime theory is that it has remained an elastic concept and has been used to analyze a huge diversity of issues, with many promising results. Regime theory should continue highlighting both the ideational and material dimensions of organization and bringing together positivist, inductive, and critical approaches to understanding power, interest, and identity so as to generate a series of new conversations or trajectories for exploring the creation of international order.

One of the most prevalent ideas in the international relations (IR) literature is that domestic political patterns are linked to foreign policy via the concept of political regime (democracy, anocracy, and autocracy). Over the past two decades, the regime type-foreign policy nexus has gained ample theoretical and empirical credibility in IR theory. There are four areas of research on regime type and foreign policy: the first considers the “democratic peace” literature focused on authoritarian and democratic foreign policies; the second deals with the “democratization and war” literature that highlights the foreign policies of anocracies; the third uses the common large-N data sets and research design and “unpacks” democratic and authoritarian regimes (separately) to identify subtypes of each regime type; and the fourth is the so-called “politics and war” literature. The politics and war literature is rather fragmented, with authors pursuing separate and evidently incomplete lines of argument. There are three steps for integrating the key insights of the politics and war literature. First, the intensification of domestic opposition to established elites. Second, the adoption of new ruling strategies as a means for leaders to cope with rising domestic political crises and/or control of their hold over the regime. Third, the occurrence of international crisis, in which larger aspects of domestic politics persist, or emerge, to affect decisions involving the threat of war.

Only recently has international environmental politics scholarship focused more explicitly on “regionalism” as a distinct phenomenon, one which has received much more sustained attention among specialists in international security and international political economy. By the early twenty-first century, regional environmental governance had become commonplace. Since the term “region” has had different connotations in different disciplines, the analytic and empirical scope of studies of regional environmental governance has varied considerably. As such, analyses of regional environmental cooperation have incorporated both constructivist views of regions that transcend the nation-state grid, and rescaling arguments placing greater emphasis on subnational governments, transboundary mobilization, and the importance of ecoregional initiatives. Regional agreements increasingly point to some sort of ecoterritoriality, state actors are increasingly complemented by nonstate or substate actors, and the thematic scope increasingly expands beyond purely environmental issues to encompass broader notions of sustainable development. There are three typical types of regional agreements: interstate regional environmental governance, ecoregional environmental governance, and ecoregional sustainable development governance. Interstate regional environmental governance is most typical of regional economic organizations with an environmental mandate that covers single or multiple environmental issues. Meanwhile, ecoregional environmental governance is widely seen in agreements for mountain ranges, regional seas, or river basins. Case studies on marine and mountain regional environmental governance illustrate that various regional arrangement remain in quite different states of institutionalization. Yet they also illustrate the growth of ecoregionalism in transnational environmental governance.
The terms “region,” “regionalism,” and “regional integration” are often used synonymously in the academe. For instance, one author refers to Pacific Asian regionalization, North American regionalism and regional integration in Europe. Some authors view “regionalism” as the analytically broader term. Since the mid-1990s, there has been a more general movement toward “economic regionalism or regional trade agreements,” building on the concept of “new regionalism” and coinciding with the notion of “preferential trading arrangements.” This implies only those integration schemes which have an economic purpose, are in geographical proximity to each other, and consist of more than two states qualify for inclusion. There are five stages in the deepening of formal regional integration: free trade area, customs union, common market, economic union, and political union. From the late-1950s to the late 1990s, two approaches have attempted to explain the process (rather than the origins) of regionalism: neofunctionalism and liberal intergovernmentalism. Scholars argue whether there is a causal connection between regional integration and Global Political Economy (GPE), or whether they are simply correlated. Three themes from the literature on regionalism and GPE can be identified. First, the numerous studies since the late 1990s that have taken a decidedly comparative approach, irrespective of their level of analysis, agree that there is some “logic” to regional arrangements. Second, confusion occurs with domestic causality. Third, large membership has become a concern for the European Union.
A proper understanding of the development of nationalism should incorporate the direct and indirect influences of religion. To focus on the current international order is to note that various aspects of international conflict have significantly changed in recent years, with frequent involvement of religious, ethnic, and cultural non-state actors. The type of religious nationalism affects what type of nation state develops. The stronger the religious influence on the national movement, the greater the likelihood that discrimination and human rights violations will occur. In addition, there are scholars who argue that the activities of transnational religious actors—such as the Roman Catholic Church, the Organisation of the Islamic Conference (OIC), and al Qaeda—can undermine state sovereignty. The premise here is that globalization facilitates the growth of transnational networks of religious actors. Feeding off each other’s ideas and perhaps aiding each other with funds, these actors and institutions are bodies whose main priority is the well-being and advance of their transnational religious community. But opinions about the current involvement of religion in international relations and its impact on international order tend to be polarized. On the one hand, the re-emergence of religion in international relations is often seen to present increased challenges to international order, especially from extremist Islamist organizations. On the other hand, some religious actors may help advance international order—for example the Roman Catholic Church and its widespread encouragement to authoritarian regimes to democratize—by significantly affecting international governments.

The term “refugee crisis” is used throughout the literature to refer to situations where large numbers of refugees or displaced persons more generally are present, whereas “humanitarian crisis” refers to situations where the lives, health, safety or well-being of a large number of people are at substantial risk. The term “complex emergency” is defined as “a humanitarian crisis typically characterized by extensive violence and loss of life, massive displacements of people, widespread damage to societies and economies, and hindrance of humanitarian assistance by security risks and political and military constraints.” A typical complex emergency consists of one or more humanitarian and refugee crises, regardless of their actual causes, and necessitates an international and United Nations system-wide response because of its complexity. Humanitarian and refugee crises have often generated international response efforts that were intended to help affected individuals, alleviate their suffering, and restore their situation from the plight of crisis to some level of normality. In addition to the UN and its specialized agencies, international responses bring together a large and diverse set of actors such as the International Committee of the Red Cross and its national societies, national and international nongovernmental organizations, and the governments of third states. Their responses have drawn scholarly interest, especially after World War II. However, the literature on international responses to humanitarian and refugee crises does not offer a comprehensive and exhaustive scholarly treatment of the issue. This is an obvious gap that needs to be addressed in future research.

The International Studies Association’s (ISA) Scientific Study of International Processes (SSIP) section is dedicated to the systematic analysis of empirical data covering the entire range of international political questions. Drawing on the canons of scientific inquiry, SSIP seeks to support and promote replicable research in terms of the clarity of a theoretical argument and/or the testing of hypotheses. Journals that have been most likely to publish SSIP-related research include the top three general journals in the field of political science: the American Political Science Review, American Journal of Political Science, and Journal of Politics. A number of more specialized journals frequently publish research of interest to the SSIP community, such as Conflict Management and Peace Science, International Interactions, International Organization, International Studies Quarterly, Journal of Conflict Resolution, and Journal of Peace Research. Together, these journals published a total of 1,024 qualifying articles between 2003 and 2010. These articles cover a wide range of topics, from armed conflict and conflict management to terrorism, international political economy, economic development or growth, monetary policy, foreign aid, sanctions, human rights and repression, international law, international organizations/institutions, and foreign policy attitudes and beliefs. Data users who are interested in conducting their own research must: choose the most appropriate data set(s), become familiar with what the data set includes and how its central concepts are measured, multipurpose data sources, investigate missing data, and assess robustness across multiple data sets.
