This year’s Colloquium on European Research in Retailing was held at University of Portsmouth Business School. The Institute for Retailing and Data Sience was represented in two sessions. Christina Holweg presented her research with Christoph Teller, Ina Marie Raible, and Gerald Reiner on “Returnable Package Systems in Retailing - Processes and Challenges”. Cordula Cerha gave a talk on “Consumer Stockpiling Motivation in Times of Ongoing, Multiple, Overlapping, and Compounding Crisis”. As usual CERR was an excellent opportunity to discuss research ideas with the European Retailing Community.
