🚨🚨🚨🚨 New WP (with @benckrick.bsky.social @austinlw.bsky.social) available at the ESOC working paper series: esoc.princeton.edu/wp39
Title: Refugee Repatriation and Conflict: Evidence from the Maximum Pressure Sanctions

Abstract: How does refugee return shape conflict in migrants’ destination communities? We argue that conditions inducing repatriation bear critically on the consequences of return. When refugees return because of worsening conditions in host countries, they are often marginalized and destitute. In this setting, mass return risks amplifying conflict in returnee-receiving communities. We test this theory leveraging the Trump administration’s sudden re-imposition of sanctions on Iran in 2018. These “Maximum Pressure” sanctions decimated the Iranian economy and spurred mass return of Afghan refugees from Iran. Exploiting historical returnee settlement patterns and the plausibly exogenous timing of the sanctions, we estimate the causal effect of large-scale refugee repatriation on violence. We find that the returnee influx increased insurgent violence in returnees’ destination communities. We find suggestive evidence for an opportunity cost mechanism. Sanctions-induced currency depreciation reduced household incomes in returnee-receiving areas, lowering reservation wages and driving up insurgent recruitment. We also find evidence that Iran retaliated against the sanctions by escalating support for Afghan insurgent factions. While insurgent violence increased in repatriation communities, there was no effect on communal conflict.
