Several foundational papers in theory are in OR or maths journals, Gale and Shapley is another exemple (but they probably did not try submitting to econ) and Myerson 1981 as well

France had a similar ruling for "vegetarian steaks" which can no longer be called steaks because of lobbying from the meat industry. But non alcoholic beer can still be called beer because these are the same companies making the alcoholic beers so hey 🤷‍♂️

The market design community (and I) is deeply missing him and we need more people like him promoting interdisciplinary collaborations to make papers with broad impact. I also learned about his humble backgroun from rural China and I felt even more impressed by him. So long my friend!

The workshop is now over thanks to all participants! This was a nice and moving tribute to Yinghua, many shared nice memories and stories about him. It showed how he had a deep impact on market design in Europe and especially in France and how broad his interests were from theory to empirics

Ca existe déjà aux US c'est probablement l'avenir, ils font des éco d'échelle sur les abonnements et mettent une limite en terme de crédit c'est ça la clé. Les 30€ donnent une limite de crédit à utiliser sur toutes les IA et après payer des paquets de requêtes ça devient un bien à consommer
