Economic sanctions research suggests that sanctioned countries’ overall economic costs tend to be low. This article argues that, despite this, sanction costs can force the governments of these countries to reallocate budget resources from low-priority spending categories to other categories in an effort to minimize their political costs. One such low-priority category is disaster preparedness and mitigation. The authors show that economic sanctions lead to reduced disaster preparedness spending and, as a result, increase the scale of economic and human losses generated by natural disasters in sanctioned countries.
