This note generalizes analytical relationships among activity variables of DEA models previously derived by Boussemart, Briec and Leleu (2007). We relax the asumption of constant returns to scale by showing that the key results hold under a weaker asumption of homogeneity. We use the notion of...

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 favorable shadow prices. This paper...

The impact of the transition from a global budget payment to an activity-based financing system on public hospitals financial equilibrium is analyzed in this paper. To do so, we develop a theoretical model where patients? demand is related to joint decisions made by hospital managers and...

Dans ce papier, nous proposons deux nouveaux indicateurs pour mesurer la performance opérationnelle et la performance financière des réseaux d’agences bancaires. Nous développons une approche alternative aux mesures classiques de productivité pour prendre en compte des effets de taille,...

Dans ce papier nous discutons l’adaptabilité des indicateurs de performance opérationnelle à l’environnement organisationnel, décisionnel et stratégique des entités évaluées. L’application empirique est réalisée sur une population de 1585 agences bancaires à partir de données...

In this paper, we apply a standard model of performance evaluation to the retail banking industry. In this framework, the global economic performance is broken down into technical efficiency related to the optimal use of resources and price efficiency related to the optimal choice of a...

Hospital financing systems determine ma jor decisions made by physicians and managers within hospitals. This paper examines the impact of the transition toward an activity-based reimburse- ment system that has emerged in most OCDE countries. We consider two initial situations, one for a private...

In this paper, we estimate a lower bound for the sum of firms' allocative efficiencies in the absence of information on prices. For this purpose, we only estimate technical efficiency at both the firm and the industry level using a directional distance function and choosing a relevant direction....

This paper analyzes the relationship between the comparative advantages of bank branches and the trade area environment. Bank branches are points of sale whose trade environment influences their activities and performance. Comparative advantages are defined, for each output mix, by the strict...
