Price and format competition with consumer confusion

Busy like a bee and still buzzing not so weakly

A very busy summer for me this year, after last year’s ban on conferences to focus on doing experiments. For me the summer started at the end of May with a research stay in Rennes, where I was invited by Eric Darmon and gave a talk about my research with Paolo Crosetto on how firms […]

Science Slam picture and video

Social preferences under uncertainty. An experiment

Every sixty nights, drawings are made and determine each citizen’s fate until the next drawing, and this with “incalculable consequences”. Like the narrator, one might end up a proconsul, or […]

Presentation of a new paper at the ESA in Cologne

  Paolo Crosetto was kind enough to make the above presentation on my behalf at the ESA European conference in Köln this year. I was not able to make it but was kept on the program so, learning this the day before, we jumped on the opportunity and I wrote the presentation in an afternoon. […]
