Inventors’ Personal Experience of Natural Disasters and Green Innovation

Abstract

We show that inventors’ personal experiences of natural disasters lead to increased green innovation. We match patent records of French and German inventors and a survey of inventive firms to detailed information on natural disasters. This allows us to exploit exogenous variation in inventors’ exposure to natural disasters. In affected areas, exposure results in an average 8.2% increase in green patents, driven primarily by increased innovation in mitigation technologies that reduce emissions. Non-green innovation remains unaffected. We do not find significant spatial spillovers in patenting, underlining the importance of being personally affected. To get at the mechanism, we investigate how natural disaster exposure changes firms’ reasons for green innovation. Affected firms adjust their higher-order beliefs regarding consumers’ demand for green goods and more stringent environmental regulation. Our findings provide novel evidence that personal experiences affect higher-order beliefs and innovation.
