We have started the new calendar year and the Spring 2026 semester with our annual workshop! Thanks for all speakers and participants for making it an interesting workshop. @ubeconomics.bsky.social

We have wrapped up the Fall seminars with a session of two talks on voting theory. Hector Hermida (Budapest University of Technology and Economics) presented “Self-equivalent voting rules” and Dimitrios Xefteris (UCyprus) presented “Efficiency in collective decision making via quadratic transfers”

Today we had Alexey Kushnir (Moroccan Game Theory Center) at our seminar series. Together with his co-author, they propose a pseudo-market mechanism w/ relevant properties to solve course allocation problem. Moreover, their simulation suggests that it outperforms the benchmark model. #econsky
