Back in the 1990s I studied economics at the University of Lausanne (HEC Lausanne), and one of my fellow students was José Anson. We both later received our doctorates at HEC, and he went on to be the chief economist of the United Nations Universal Postal Union. I went on to pursue an academic career. Now, many years later, we have published a joint paper in which we study how industry change was framed in the postal sector in the aftermath of the financial crisis. What a pleasure to collaborate with old friends.
