Rankings and university performance: A conditional multidimensional approach

Daraio, Cinzia; Bonaccorsi, Andrea; Simar, Léopold - In: European Journal of Operational Research 244 (2015) 3, pp. 918-930

University rankings are the subject of a paradox: the more they are criticized by social scientists and experts on methodological grounds, the more they receive attention in policy making and the media. In this paper we attempt to give a contribution to the birth of a new generation of rankings,...
