Why might female leaders of democratic countries commit more money, equipment, soldiers, and other resources to interstate conflicts than male leaders? We argue that gender bias in the process of democratic election helps explain this behavior. Since running for office is generally more costly for women than for men, only women who place a higher value on winning competitions will choose to run. After

Conventional wisdom holds that open, collaborative, and transparent organizations are innovative. But some of the most radical innovations—satellites, lithium-iodine batteries, the internet—were conceived by small, secretive teams in national security agencies. Are these organizations more innovative because of their secrecy, or in spite of it? We study a principal–agent model of public-sector innovation

Across countries and over time, support for economic globalization is strongest among individuals with the highest levels of education. Yet despite long-lasting debates on the sources of this correlation, reliable evidence that isolates the causal effect of education from the nonrandom selection of individuals into education is lacking. To address this fundamental issue, I exploit compulsory-schooling

Human rights are a fundamental principle and purpose of the United Nations (UN). Yet, UN peacekeeping operations (PKOs) exhibit substantial variation in their ability to engage in human rights activities. While existing research has investigated deployment and mandates, we explain what peacekeepers can actually do on the ground. We argue that the UN Security Council’s permanent member states (the P5)

The notion of affinity among countries is central in studies of international relations: it plays an important role in research as scholars use measures of affinity to study conflict and cooperation in a variety of contexts. To more effectively measure affinity, I argue that it is necessary to utilize multidimensional data and take into account the network context of international relations. In this

Why do protests emerge and endure in some localities but not others? This study focuses on urban protests in the city of Tehran, Iran’s capital and largest city, during the 2022 uprising to explain why protests emerged and endured in some neighbourhoods but not others. Using an original geocoded dataset of 339 protest events at the neighbourhood level, I test two competing sets of demographic and spatial

What effect does the institutional design of international organizations (IOs) have on their domestic support? In this article, we focus on interactions between citizens’ social identity and institutional characteristics that may have the potential to polarize citizens’ IO attitudes. We argue that citizens’ cosmopolitan identity makes them react in diametrically opposed ways to IO settings on the authority

This study explores how race impacts the legitimacy of international organizations (IOs). Specifically, we examine whether the representation of Black people in IO leadership positions influences perceptions of IO legitimacy among Black and white individuals. To do so, we fielded seven survey experiments in two racially diverse countries, South Africa and the United States, and three experiments in

In 2014, Russia denied that its military was assisting separatists in eastern Ukraine, despite overwhelming evidence. Why do countries bother to deny hostile actions like this even when they are obvious? Scholars have argued that making hostile actions covert can reduce pressure on the target state to escalate. Yet it is not clear whether this claim applies when evidence of responsibility for the action

Why do rebel splinter groups emerge during peace processes, and who chooses to defect? Since Colombia's landmark peace agreement with the FARC in 2016, roughly half of the territory once controlled by the group has seen a resurgence of rebel activity by FARC splinter groups. I argue that the FARC's return to arms is a case of “middle-out fragmentation,” whereby opportunities for profit induce mid-

Powersharing institutions are often prescribed to enhance civil peace, democratic survival, and the equitable provision of public services, and these institutions have become more prevalent over time. Nonetheless, the past decade has seen a rise in democratic backsliding and competitive authoritarianism, raising questions about how the relationship between powersharing, democracy, and civil peace may

Processes that occasionally, but not always, produce extreme values are notoriously difficult to model, as a small number of extreme observations may have a large impact on the results. Existing methods for handling extreme values are often arbitrary and leave researchers without guidance regarding this problem. In this paper, we propose an extreme value and zero-inflated negative binomial (EVZINB)

Does economic deprivation fuel terrorist recruitment? A large empirical literature has explored this question, but the findings remain contradictory and inconclusive. We argue that this is due to inconsistencies in the way deprivation has been defined and measured. This article identifies these deficiencies and provides a roadmap toward more precise measurement of deprivation and consequently toward

There is a scarcity of systematic data regarding the military equipment of rebel groups engaged in intrastate conflicts. This empirical gap has impeded the rigorous evaluation of (formal) theories concerning militarized interactions between governments and rebel groups. To address this deficiency, we have developed the Rebels' Armament Dataset (RAD). This dataset provides detailed information on the

Why do countries mutually agree to constraints on their behavior? Why do they comply with such constraints in the absence of enforcement mechanisms? More specifically, why did NATO allies, with disparate geography and perceptions of the international security environment, agree to ‘aim to move towards’ increased defense spending (2% of GDP on defense and 20% of defense budgets on equipment modernization)

OpenAI’s ChatGPT language model has gained popularity as a powerful tool for problem-solving and information retrieval. However, concerns arise about the reproduction of biases present in the language-specific training data. In this study, we address this issue in the context of the Israeli–Palestinian and Turkish–Kurdish conflicts. Using GPT-3.5, we employed an automated query procedure to inquire

This article introduces the Issue Correlates of War Identity Claims Dataset. An identity claim occurs when two states diplomatically contest the treatment of an ethnic group that both states share. A state that advances such a claim (i.e. the challenger) demands that the other state (i.e. the target) either: (i) change its domestic treatment of the group, (ii) grant the group independence, or (iii)

Transnational surveillance is a powerful tool in the arsenal of autocrats the world over. Despite its pervasive use in extraterritorial coercion, the systematic study of surveillance of regime opponents beyond national borders remains underdeveloped in political science, primarily due to limited data availability. To help fill this gap, we constructed the Latin American Transnational Surveillance dataset

Studies of migration-related security concerns have focused on the emergence of these concerns through securitization or their potential dissolution through desecuritization. This paper challenges the conventional view of these processes—securitization and desecuritization—as oppositional and mutually exclusive. Instead, it argues that they are imbricated in complex ways in an arena of contestation

Are publics in great power democracies more likely to approve of foreign armed combatants that comply with international humanitarian law (IHL)? There is a wealth of evidence that armed combatants with an incentive to seek the support of outside compliance constituencies are more likely to adhere to IHL. Yet a key mechanism underlying these claims—that people in great power democracies are more likely

Why do contemporary states fortify their borders? Modern military advancements have made such fortifications obsolete for security, yet scholars have offered no satisfactory alternative theory. I propose a theory of fortifications with economic motivations using a game-theoretic model where states compete to extract wealth over a shared population around a border. Such competition generates inefficiency

This article explores who is likely to benefit from Internet propaganda in civil wars. It argues that the global reach of the Internet, its lack of regulation and its filtering tools are more likely to help transnational rebel groups with external support and radical aims than local groups with home-grown support and moderate aims. The paper then introduces a new dataset on rebel propaganda that includes

Transitional justice practices frequently involve public apologies where former combatants confess their wrongdoings and ask for forgiveness, with the underlying assumption that such displays facilitate the reintegration of ex-combatants into society. However, little is known about the public response to ex-combatant apologies. In this article, we investigate the causal effect of an armed group apology

This paper analyses how pre-pandemic levels of inequality across US counties have shaped the impact of the COVID-19 pandemic on the incidence of protests. The results from difference-in-differences and instrumental variable models using high-frequency weekly data show that more stringent measures to contain the pandemic increased the incidence of protests, but only in US counties with high levels of

New political issues and opportunities lead new actors into contentious politics. This article studies one such case: transnational migrants making claims and engaging in collective action when traversing state borders. As global migration flows and accompanying political backlash has grown since the mid-2010s, borders have increasingly become sites of contention between groups of migrants seeking

The COVID-19 crisis created, and continues to produce, unprecedented challenges globally. Marginalized and racialized families, communities, and nations are experiencing their worst impacts, and in particular, women and girls are the hardest hit. The most pressing concerns raised by COVID-19 include a surge in gender-based violence, a rise in care burden, the feminization of poverty, and growing unemployment

Can armed conflict amplify the societal impacts and humanitarian consequences of natural hazards? Given that these hazards affect millions of people worldwide and that climate change is expected to increase the frequency and intensity of extreme weather events, it is paramount that we advance our understanding of what makes societies vulnerable to these hazards. Existing research has focused mainly

The article argues that International Relations, and especially those approaches that are informed by the epistemological and methodological premises of reflexivity, would benefit from a more diversified range of comparative methodologies other than those deriving from the work of J.S. Mill and more recent developments within the neopositivist canon. While discussions of methodology in International

Are civil wars shaped by how they start? While existing literature points to the path-dependent nature of conflict, the link between the type of onset and wartime dynamics have been largely overlooked. Building on a recent typology capturing the dynamics of civil war onset (1944–2020), I analyze conflict trajectories, focusing on three macro-level wartime dynamics: warfare, intensity, and duration

Conflicts involving pastoralists have been on the rise in the past two decades in West, Central and East Africa. This article argues that land alienation is a major source of this type of violence. We employ a narrow identification strategy of relevant pastoral conflicts based on the Armed Conflict Location Event Dataset and create a unique indicator of land alienation comprised of three types of land

Relational scholarship is burgeoning across the social sciences and gaining ground in peace and conflict studies. But relationalism is prone to misunderstanding. This article demonstrates that the ‘relational’ is an ontological orientation, with foundational implications for how social scientists know the world, rather than a methodological stance oriented to relationships. It offers a threefold framework

In a world of accelerated movements, this article examines how infrastructures matter in international relations. We first show that the International Relations (IR) discipline has relegated infrastructures to the background of their studies and treated them as passive tools despite their forcible role in the establishment of the modern state system. By adopting a sociological definition of “the international

This paper is concerned with state capacity and autocrat survival. We argue that state strength in autocracies increases leader tenure but reduces the stability of the regime itself; stronger autocracies run a higher risk of transitioning to democracy. This trade-off arises as a result of how state capacity affects the behavior of elite challengers. A stronger state reduces the likelihood of the ruler

For years, scholars in international relations have addressed questions related to regime complexity and its effects. However, there is a lack of understanding of how individuals react to clashes of international law obligations when assessing domestic policies. In this article, we study the extent to which citizens are concerned with compliance and noncompliance with international law when their governments

The category of the nomad has gained a newfound salience in recent decades, ranging from public interest in “digital nomadism” to academic debates about “nomadic theory.” Faced with this upsurge of interest in nomadism, this collective discussion brings together five scholars of diverse theoretical and academic backgrounds to investigate the pasts, presents, and possible futures of the nomad category

This paper draws on fieldwork interviews with migrants who fled their home countries (Somalia, Eritrea, and Sudan) and irregularly traveled through Sudan, Sahara, Libya, and the Mediterranean Sea, eventually reaching Europe. It demonstrates how, throughout their journeys, migrants were targeted by various armed groups (particularly non-state) for purposes including recruitment, extortion, ransom, immobilization

This article explores the importance of what we call “decolonial deconstruction” for contemporary global politics and policy discourses and develops a critique of this approach. “Decolonial deconstruction” seeks to keep open policy processes, deconstructing liberal policy goals of peace, democracy, or justice as always “to come”. It emerged through a nexus of postmodern and decolonial framings, well

This article theorizes smartphone detoxing as a practice of sovereignty. The article begins by arguing that the smartphone enables the exercise of psychopolitical control, a new mode of neoliberal governmentality under which individuals are governed through the algorithmic modification of behavior. Against this background, smartphone detoxing can be seen as a practice of sovereignty in the sense that

s How does military experience change individual foreign policy preferences? Prior research on military service focuses on the effects of combat experience on political participation and policy preferences, but combat is not the only military experience that influences attitudes. Living overseas is a common military experience with the potential to shape foreign policy preferences. Using observational

Between 2017 and 2021, Vietnam saw the fastest annual proportional increase in renewables ever seen across the world. This was financially supported by the state-owned energy company, Vietnam Elect...

In this study, we experimentally test the theoretical results of a contest game between groups when the value of the prize is fixed and when it is endogenously determined. It can decrease with contest efforts of all groups as in the case of an armed conflict or a lawsuit. The value of the prize can also increase with contest efforts as in the case of a patent race. We also analyze the impact of different

The militarization of border control is a defining feature of contemporary international politics. Why do states flock toward these policies despite their questionable efficacy? We theorize that border militarization stems in part from public reactions to the threat of international and domestic decline. We test this argument with two conjoint experiments that randomize the implementing agency, strategy

It is often proposed that the young unemployed are more likely to engage in political violence, conflicts, and protests. One problem in studying the unemployed – especially in the Global South – are the blurred lines between the unemployed, the employed, and those working in the informal sector. Further, the employed are a heterogeneous group so employment quality might also play an important role

Many theories attempt to explain the determinants of preferential trade agreements (PTAs) and their design. Existing accounts, however, focus almost exclusively on structural or domestic factors and ignore individual leaders. In this paper, I develop and test novel theoretical claims regarding executive leaders’ prior career in business and their trade cooperation policy once in office. I construct

Many types of civil unrest, including protest, violent conflict, and rebellion, have been found to be subject to both inter- and intra-state contagion. These spillover effects are conventionally tested through the application of parametric structural models that are estimated using observational data. Drawing on research in methods for network analysis, we note important challenges in conducting causal

One of the most fundamental economic policy choices a society makes is how to order its global economic relations. What models do states use to structure this multifaceted decision, and how do they choose among these alternatives? We combine data on trade policies, foreign investment, exchange rates, capital flows, and international treaties to discover states’ strategies of global economic engagement

s Do military alliances promote human rights? Scholars and practitioners generally believe they do not because states form alliances largely to advance their strategic interests and thus are not interested in members' domestic policies. I claim that some states may care about their allies' human rights practices. Specifically, democracies are concerned that alliance relationships with rights-abusing

s The growth and success of right-wing populist movements globally has been remarkable since the early 2010s. Indeed, populist parties in Europe, Asia, Latin America, and North America have received tremendous electoral success, shaping a movement for the people and by the people within the political sphere. To what extent do populist movements influence other such programs across national borders

Offshore finance allows foreign banks to create US dollars under the laws of an offshore jurisdiction. How and why does this affect international monetary power? Conceptually, I argue that offshore finance bifurcates across borders the shared power of the state and banks to create money, combining the US dollar with mostly English law. Empirically, I demonstrate that more US dollars are created offshore

This article introduces a new phenomenon in the study of civil war: tribal wartime social order. The proposed theory of tribalocracy, or tribal rule, integrates insights from civil war studies, anthropology, and sociology to provide a nuanced account of social order and its transformation in tribal warzones. Drawing on extensive fieldwork in the Hauran region in southern Syria, the proposed theory

Critical methodologies in International Political Sociology (IPS) and its intersecting fields and research traditions have increasingly coalesced around the idea that research should be done in dialogue, and possibly cooperation, with people rather than only about them. Drawing together research under this theme and wider debates on participatory, activist, and action research, alongside our own research

This Collective Discussion aims to open up space for an international political sociology of the production of historical knowledge that interrogates the politics around benchmark dates and what becomes knowable and unknowable through them. Specifically, it examines 1492 as a historiographical device through which to unpack how the discipline of IR knows history. 1492 presents a relevant case for this

At the 1892 International Sanitary Conference in Venice, experts established international health politics as governing the flows of people, traffic, and information. This focus has remained ingrained in current health politics and shaped the international response to the COVID-19 pandemic. This paper focuses on the micropolitics among these experts to understand the emergence of such governance expertise

The archives of migration are piecemeal and scattered. This is both an epistemological problem, and a matter of political concern in an international order that forces people to migrate, racializes them, and renders them subject to violence. In response, we explore the potential of counter-archiving migration. First, we explain why archives matter politically, and consider which traces of migration

Women increasingly feature in nuclear diplomacy, both as participants and as subject matter. Research institutes report a steady increase in women's representation in large multilateral disarmament forums. Diplomats emphasize the importance of women in statements and working papers. The recent conversation on women in nuclear diplomacy forms part of a wider discourse on women in the nuclear weapons
