From March 30th to April 1st 2022, Thomas Grebel and Xijie Zhang, together with Uwe Cantner and Nils Grashof (Friedrich-Schiller-University Jena), participated in a workshop within their DFG research group "Multiple Competition in the Higher Education System" in Kassel. Xijie Zhang and Nils Grashof presented the work progress of the project "(Autonomous) Universities in Dynamic Competition". One of the issues addressed was the question of scale efficiency of universities: are some universities possibly too small or too large to achieve their goals efficiently? The results so far provide some first insights. In the next phase of the project, the empirical analysis of university competition in Germany will be deepened.
