The macroeconomic costs of conflict

Abstract

Macroeconomic costs of conflict are generally very large, with GDP per capita about 28 percent lower ten years after conflict onset. This is overwhelmingly driven by private consumption, which falls by almost 25 percent ten years after conflict onset. Conflict is also associated with dramatic declines in official trade, with exports (imports) estimated to be 58 (34) percent lower ten years after conflict onset. The onset of conflict often also induces significant refugee outflows to neighboring non-advanced countries in the short run, and relatively small but very persistent refugee outflows to advanced countries over the long run. To alleviate reverse causality concerns between GDP and conflict onset, we control for pre-conflict GDP forecasts from the IMF World Economic Outlook and show that similar results are obtained with and without pre-conflict GDP forecasts.
