We examine the impact of Hurricane Harvey on retail businesses and consumers. Using granular data on flooding and card expenditures, we show that Harvey-induced flooding caused a modest increase in establishment exit. Using a model of consumer demand, we find that Harvey-induced exits reduced consumer welfare by less than 2% on average, but that welfare decreased by more than 12% in the hardest-hit census tracts. We discuss how to optimally allocate business aid after natural disasters.
