[fre] Comparaison des différentes mesures d'efficacité technique : une application aux centres hospitaliers français . par Hervé Leleu et Benoît Dervaux . L'engouement pour les techniques non paramétriques d'estimation de frontières de production dans le domaine hospitalier tient à leur...

This paper extends the recent work by Frei and Harker on projections onto efficient frontiers (1999) in three ways. First, we provide a formal definition of the production set as the intersection of a finite number of closed halfspaces. We emphasize the necessity of a complete enumeration of the...

The paper addresses the decomposition of firms’ profit inefficiency (i.e. the difference between the observed profit and the maximal profit that could have been earned) in a context of output price uncertainty. More precisely, we separate this inefficiency into price expectation error,...

The duality between measures of economic and technical efficiency has been extensively studied in the productive efficiency analysis. This duality ensures a meaningful interpretation of technical efficiency as economic efficiency evaluated at the most favourable shadow prices. This paper...
