Mass Population Displacement and Retail Activities in the Wake of Hurricane Katrina

Abstract

This week marks the 10th anniversary of Hurricane Katrina's tragic landfall near New Orleans, Louisiana, and the forced relocation of hundreds of thousands of families who lost their homes in the disaster. This mass population displacement boosted, for an extended period, population density and store frequentation in areas that were relatively spared by the storm. This note argues that supermarkets that weathered the hurricane raised prices little despite facing markedly higher store traffic and likely disruptions to their supply chains.
