Approximations and inference for nonparametric production frontiers

Daraio, Cinzia; Simar, Léopold - 2022

Nonparametric methods have been widely used for assessing the performance of organizations in the private and public sector. The most popular ones are based on envelopment estimators, like the FDH or DEA estimators, that estimate the attainable sets and its efficient boundary by enveloping the...

Rankings and university performance: a conditional multidimensional approach

Daraio, Cinzia; Bonaccorsi, Andrea; Simar, Leopold - Dipartimento di Ingegneria Informatica, Automatica e … - 2014

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,...
