We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...

We assess the robustness of previous findings on the determinants of terrorism. Using extreme bound analysis, the three most comprehensive terrorism datasets, and focusing on the three most commonly analyzed aspects of terrorist activity, i.e., location, victim, and perpetrator, we re-assess the...

Can religiosity sway a society's propensity for violence against outgroups? We first introduce two state-year-level religiosity measures for several pre-Enlightenment European states with the frequencies of (i) religious language in book publications and (ii) Christian names of newborns. To...

Many experts claim that the incidence of suicide attacks is driven by religious cleavages. To test this hypothesis, we investigate whether the total number of suicide attacks per violent conflict or the annual number of suicide attacks per country is associated with simmering religious...

This study examines the causal joint effect of a new political regime and war against Iraq on life expectancy of Iranians for the period 1978–1988 during the revolution and war. I use a synthetic control approach to construct a synthetic Iran based on a weighted average of other Middle East...

What is the strategic role of membership in an intergovernmental group with unanimity requirements if the group negotiates with an external player in a setting with incomplete information? Being in such a group has a strategic effect compared to negotiating as a stand-alone player and reduces...

We analyze how trade openness matters for interstate conflict over productive resources. Our analysis features a terms-of-trade channel that makes security policies trade-regime dependent. Specifically, trade between two adversaries reduces each one’s incentive to arm given the opponent’s...

In an interconnected world, economic and political interests inevitably reach beyond national borders. Since policy choices generate external economic and political costs, foreign state and non-state actors have an interest in inflencing policy actions in other sovereign countries to their...

We investigate the effects of US-imposed trade sanctions on the global trade patterns of sanctioned countries by employing a gravity model that incorporates data spanning from 1980 to 2020 across 79 nations. The results reveal that both partial and complete US sanctions lead to significant...
