Using georeferenced data on affiliates and headquarters of multinational enterprises together withg eoreferenced conflict data, this work is the first to establish a causal link between activities of multinational enterprises and violence. Results show that the activity of affiliates increasing locals' human capital significantly decreases conflict probability, while the activity of affiliates of exploitative sectors significantly increases conflict, in particular in the agriculture and forestry sectors. This increase in conflict likelihood is magnified in areas with politically unrepresented ethnic groups, and/or targeted for large-scale land acquisition.
