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...

We study the 420 US drone strikes in Pakistan from 2006-2016, isolating causal effects on terrorism, anti-US sentiment, and radicalization via an instrumental variable strategy based on wind. Drone strikes are suggested to encourage terrorism in Pakistan, bearing responsibility for 16 percent of...

We analyze the effects of Russia's invasion of Ukraine, the partial military mobilization, and the Wagner Group rebellion on a broad set of sentiments in the Russian population, using the exogenous timing of surveys from Gallup World Poll and the Levada Center. Our results show strong rally...

Persecution, pogroms, and genocide have plagued humanity for centuries, costing millions of lives and haunting survivors. Economists and economic historians have recently made new contributions to the understanding of these phenomena. We provide a novel conceptual framework which highlights the...

In the context of a global security framework that mitigates interstate conflicts, nation-states establish a reputation for resolve by supporting foreign insurrections. Our theoretical predictions indicate that states with a greater number of co-ethnic groups abroad are more inclined to endorse...
