The impacts of disaster on international trade

How democracy levels affect trade flows if a country is struck by a disaster

This paper examines the impact of major disasters on international trade flows using a gravity model. The analysis is based on data of more than 170 countries for the years 1962-2004 yielding approximately 300,000 observations.

The paper finds that the driving forces determining the impact of such events are the democracy level and, to a lesser extent, the area of the affected country:

  • the less democratic and the smaller a country the more are its trade flows reduced in case it is struck by a disaster
  • this result is stable across different countries and the most conservative estimate implies that, for a given democracy level, an additional major disaster reduces imports on average by 0.3% and exports by 0.1%
  • there are also differences in impact on an importing and an exporting country, with production capacity in small exporting countries being particularly vulnerable to external shocks.
