Abstract
This paper defines the global economic costs of conflict and suggests two key criteria, namely comprehensiveness and consistency, which are necessary for a valid calculation of such costs. A critical review of the literature reveals that most studies focus on national income losses, using counterfactual regression models, finding a negative impact on growth both for conflict countries themselves and for their neighbors. However, the debate is quite fragmented and the literature fails to combine these insights in a comprehensive and consistent manner. Furthermore, there is little work thus far on integrating aggregate and micro‐level estimates of the costs of conflict.
