Floods, earthquakes and hurricanes cause significant loss of life and destruction of property in many countries. The incidence of such disasters has increased in recent years. There is a growing consensus, however, that being better prepared against natural disasters can be equally or more effective than immediate aid and relief.
Several studies have shown that migrants send additional remittances after severe shocks. However, there is little evidence of whether and how they help households prepare for natural disasters. In a recent paper for a forthcoming World Bank-UN assessment of the economics of disaster risk reduction, we analyze cross-country macroeconomic data as well as a number of household surveys to examine the "ex-post" response of remittances to natural disasters and their contribution to "ex-ante" preparedness.
