摘要：We analyze the economic impacts of floods using new data on 3,184 large flood events in 118 countries between 1985 and 2008. We use panel vector auto-regressions to trace the dynamic response of output to three types of flood shocks. Our results robustly indicate that flood shocks tend to have a positive average impact on GDP growth, that this impact is limited to developing countries, that the effect is not confined to the agricultural sector, and that it is stronger when it is accompanied by an increase in gross fixed capital formation.
