The unintended consequences of UN sanctions: A qualitative comparative analysis

Sanctions are widely used foreign policy tools in reaction to crises in world politics. Accordingly, literature on sanction effectiveness—their intended consequences—is abundant. Yet, fewer studies address the unintended consequences of restrictive measures. This is remarkable given that negative externalities are well documented. Our article explores this phenomenon by asking under which conditions sanctions yield negative externalities. We develop a theoretical conceptualization and explanatory framework for studying the unintended consequences of UN sanctions. Empirically, we draw on data from the rich, but scarcely used Targeted Sanctions Consortium and apply qualitative comparative analysis (QCA) to examine negative externalities of UN sanctions, complemented by illustrations from the cases Haiti and North Korea. The results document the existence of multiple pathways toward unintended consequences, highlighting the negative impact of comprehensive and long-lasting sanctions, as well as the ability of autocratic targets with economic means to persist unscathed from sanctions
