Government Assistance, Bank Screening, and Firm Investment: Evidence from a Natural Disaster

Abstract

Natural disasters dramatically affect firms, but they also provide an opportunity to start anew. We exploit the 15-16 October 2017 Portuguese wildfires and the ensuing official assistance that subsidized 85% of the losses and entailed bank screening, applying a differences-in-differences approach. Firms that received government assistance subsequent to the wildfires increase output, the book value of fixed assets, employment, productivity, borrow long-term credit, and hoard cash. Overall, the evidence supports the “build back better” effect, the “broken window” fallacy at the one-year horizon, and a Keynesian multiplier effect in a two- to three-year window.
