We summarize and extend the existing frontier literature by outlining proper ways of decomposing efficiency using both radial and nonradial efficiency measures when using nonparametric, deterministic frontier models. Our contribution relates to a recent paper of Viton (Transportation Research-B...

This note illustrates the potential impact of the specification of a convex production technology on establishing minimal costs compared to the use of a non-convex technology when benchmarking electricity distributors. This methodological reflection is mainly motivated by recent engineering...

This paper proposes a nonparametric efficiency measurement approach for the static portfolio selection problem in mean-variance-skewness space. A shortage function is defined that looks for possible increases in return and skewness and decreases in variance. Global optimality is guaranteed for...

This empirical application investigates the eventual presence of credit constraints using a panel of French farmers. The credit-constrained profit maximization model proposed by Färe, Grosskopf, and Lee is extended in three ways. First, we rephrase the model in terms of directional distance...

This paper proposes a pragmatic, discrete time indicator to gauge the performance of port-folios over time. Integrating the shortage function (Luenberger, 1995) into a Luenberger portfolio productivity indicator (Chambers, 2002), this study estimates the changes in the relative positions of...

The present study fills a gap between the benchmarking literature and multi-output based efficiency and productivity studies by proposing a benchmarking framework to analyze total factor productivity (TFP). Different specifications of the Hicks-Moorsteen TFP index are tailored for specific...

Successive CAP reforms have increased the exposure of European agriculture to market forces. As a result, farmers have become preoccupied with their competitiveness and have progressively adopted best practices. However, these longrun technological adjustments could be slowed down by eventual...

[fre] Rationalisation de l'offre de soins en chirurgie. Réduction des surcapacités et réallocation sectorielle. . Dans cette étude, nous tentons d'apporter un éclairage quantitatif au débat sur la réorganisation de l'offre de soins chirurgicaux. Nous recourons à un modèle de...
