We study the influence of natural disasters on technological innovation for a panel of 49 countries. After controlling for endogeneity issues and using several measures of natural disasters (occurrences, deaths, affected people, and economic damages) we find that natural disasters have a significantly negative effect on technological innovation. We also study the disaggregated effects of natural disasters and find that earthquakes, extreme temperatures, floods, and storms influence innovations most.

识别自然灾害对技术创新的影响

我们为49个国家/地区的小组研究了自然灾害对技术创新的影响。在控制了内生性问题并使用了几种自然灾害（发生，死亡，受影响的人和经济损失）的度量之后，我们发现自然灾害对技术创新具有显着的负面影响。我们还研究了自然灾害的分类影响，发现地震，极端温度，洪水和风暴对创新的影响最大。
