The Two Faces of Opposition to Chemical Weapons: Sincere Versus Insincere Norm-Holders

Prominent research holds that the use of weapons of mass destruction is taboo. But how strong are these norms? Investigating this question among the mass public, we argue that some citizens actually support taboo policies in private but are unwilling to express counter-normative opinions openly due to fear of social sanction. These insincere norm-holders are difficult to identify empirically because they are observationally equivalent to sincere norm-holders in direct-question surveys. To overcome this challenge, we use a list design, which allows survey respondents to indirectly express sensitive opinions. The results from three list experiments show that between 10% and 17% of Americans falsify their preferences over chemical weapons use when asked directly. In an extension, we explore our framework in the realm of nuclear weapons and elite behavior. Our findings advance a specific debate on the strength of weapons taboos, while our conceptualization of insincere norm-holders and methodological application have broader implications for how scholars might think about and measure norms in international politics.

Sanctioning the Homeland: Diasporas’ Influence on American Economic Sanctions Policy

Why do some immigrant groups succeed in influencing the U.S. government to impose economic sanctions on their former dictators, while others do not? This paper begins by noting that the president is the pivotal player in sanctions policy and that presidents cater to voters in swing states. Therefore, a diaspora’s proportion of the swing-state electorate should determine whether the American government imposes sanctions on their former homeland. Considering dictatorships from 1946 to 2005, this paper finds that a one-percentage-point increase in the diaspora’s proportion of the swing-state electorate increases the probability of regime-change sanctions by 11 percentage points. It then calculates causal estimates of the effectiveness of these sanctions on regime change. Using the diaspora’s proportion of the swing-state electorate as an instrumental variable for the presence of economic sanctions, it finds that sanctions do not have a positive, statistically-significant impact on regime change while a negative impact is plausible.

Oil Price Shocks and Conflict Escalation: Onshore versus Offshore

We reconsider the relationship between oil and conflict, focusing on the location of oil resources. In a panel of 132 countries over the period 1962-2009, we show that oil windfalls escalate conflict in onshore-rich countries, while they de-escalate conflict in offshore-rich countries. We use a model to illustrate how these opposite effects can be explained by a fighting capacity mechanism, whereby the government can use offshore oil income to increase its fighting capacity, while onshore oil may be looted by oppositional groups to finance a rebellion. We provide empirical evidence supporting this interpretation: we find that oil price windfalls increase both the number and strength of active rebel groups in onshore-rich countries, while they strengthen the government in offshore-rich ones.

Does Insurgent Selective Punishment Deter Collaboration? Evidence from the Drone War in Pakistan

Scholars of civil wars have long argued that non-state actors can use selective punishment to reduce collaboration with state adversaries. However, there is little systematic evidence confirming this claim, nor investigation into the mechanisms at play. In this paper, we provide such evidence from the drone war in Pakistan. Militants in Pakistan’s tribal areas engaged in a brutal counterespionage campaign with the aim of reducing collaboration with the United States. Our analysis combines a novel dataset of collaborator killings with data on drone strike outcomes. We find that strikes killed half as many militant leaders and fighters following collaborator killings and that this suppressive effect likely works by deterring spying in the future. Beyond providing an empirical confirmation of the selective punishment hypothesis, our paper suggests an unacknowledged vulnerability of the drone program to reprisals against local allies and collaborators that limits its effectiveness as a long-term tool of counterterrorism.

A Liberal Peace?: The Growth of Liberal Norms and the Decline of Interstate Violence

How have understandings of fundamental norms of international society changed over time? How does this relate to the decline of interstate violence since 1945? Previous explanations have focused on regime type, domestic institutions, economic interdependence, relative power, and nuclear weapons, I argue that a crucial and underexplored part of the puzzle is the change in understanding of sovereignty over the same period. In this article, I propose a novel means of examining change in these norms between 1970 and 2014 by analyzing the content of UN Security Council resolutions. This analysis is then utilized in quantitative analysis of the level of violence dispute participants resorted to in all Militarized Interstate Disputes in the period. I find that as liberal understandings of fundamental norms have increased, that the average level of violence used has decreased. This points to a crucial missing component in the existing literature: that institutions can only constrain when political actors share the right norms.

What’s Fair in International Politics? Equity, Equality, and Foreign Policy Attitudes

How do concerns about fairness shape foreign policy preferences? In this article, we show that fairness has two faces—one concerning equity, the other concerning equality—and that taking both into account can shed light on the structure of important foreign policy debates. Fielding an original survey on a national sample of Americans, we show that different types of Americans think about fairness in different ways, and that these fairness concerns shape foreign policy preferences: individuals who emphasize equity are far more sensitive to concerns about burden sharing, are far less likely to support US involvement abroad when other countries aren’t paying their fair share, and often support systematically different foreign policies than individuals who emphasize equality. As long as IR scholars focus only on the equality dimension of fairness, we miss much about how fairness concerns matter in world politics.

Quick on the Draw: American Negativity Bias and Costly Signals in International Relations

States signal their intentions to domestic and foreign audiences but are not always believed. Why do people believe some state signals but not others? Using a survey experiment on a representative sample of the US public, this study finds that individuals have a negativity bias when assessing the credibility of state signals. They take other states’ aggressive actions as evidence of deep hostility but are skeptical of the credibility of conciliatory gestures. The experimental result shows that the mobilization of a small proportion of an army is perceived credible enough as an aggressive action, while the removal of even a large proportion is not perceived as conciliatory. The psychological mechanism found here is a strong foundation for theorizing about how individuals process information embedded in state signals and can improve our understanding of signaling.

Measuring Human Rights Abuse from Access to Information Requests

Existing measures of human rights abuses are often only available at the country-year level. Several more fine-grained measures exhibit spatio-temporal inaccuracies or reporting biases due to the primary sources upon which they rely. To address these challenges, and to increase the diversity of available human rights measures more generally, this study provides the first quantitative effort to measure human rights abuses from textual records of citizen-government interactions. Using a dataset encompassing over 1.5 million access-to-information (ATI) requests made to the Mexican federal government from June 2003 onward, supervised classification is used to identify the subset of these requests that pertain to human rights abuses of various types. The results from this supervised machine learning exercise are validated against (i) gold standard ATI requests pertaining to past human rights abuses in Mexico and (ii) several accepted external measures of sub-national and sub-annual human rights abuses. In doing so, we demonstrate that the measurement of human rights abuses from citizen-submitted ATI request texts can provide measures of human rights abuse that exhibit both high validity and notable spatio-temporal specificity, relative to existent human rights datasets and variables.
