      By: Shunyuan Zhang, Dokyun Lee, Param Singh and Tridas Mukhopadhyay
      We examine whether and how ride-sharing services influence the demand for home-sharing services. Our identification strategy hinges on a natural experiment in which Uber/Lyft exited Austin, Texas, in May 2016 due to local regulation. Using a 12-month longitudinal...  View Details

      Canary Categories

      Past customer spending in a category is generally a positive signal of future customer spending. We show that there exist “Canary Categories” for which the reverse is true. The more customers purchase in these categories, the less likely these customers are to return...  View Details
