[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 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...

For three decades a growing interest in the modeling of desirable and undesirable outputs has led to a theoretical and methodological debate in the nonparametric literature on production technology and efficiency. The first main discussion is about the way of modeling ‘bad/undesirables’ as...
