Sometimes, the timing just works out: Tomorrow, I’ll be discussing the concept of zero-sum and non-zero-sum games in a lecture. This article fits perfectly, so we’ll read it together. That probably means we’ll watch fewer videos of Hollywood movies featuring 'Chicken'—so, a bit less 🍿🍿 😉 #TeachEcon

Last week, Ariel Ezrachi was at our Düsseldorf law faculty as the 1st Visiting Professor 👨‍🏫 . We had several events, but what I loved most was his inspiring discussion with my students in the #antitrust class. (I was a bit proud of them.) Thanks, Ariel! @hhu.bsky.social
