| Summary/Abstract |
This research note extends the Bara and Hultman (2020) study on the effectiveness of non-UN peacekeeping missions in terms of curbing one-sided violence (OSV) against civilians. In particular, we employ two novel instruments to address the two-way causality between the number of non-UN peacekeepers and OSV measures. For each panel year, our instruments involve the interaction between the sum of various designated peacekeepers contributed and the inverse distance between the capitals of contributor and conflict countries. As required, the instrument satisfies the necessary inclusion and exclusion (exogeneity) requirements. The instrument-based results establish a robust reduction in government OSV stemming from the number of non-UN peacekeepers deployed. That reduction also holds for propensity-score matching and the inclusion of UN peacekeepers in the same regression. Non-UN peacekeepers did not have a robust influence on rebel OSV.
