In this paper, we question the definition of a financial technology that results from the application of a traditional methodology with DEA to the analysis of portfolios of financial assets. We acknowledge the previous applications and show how two approaches have been adopted until now in the...

The model used, GAMEDE, is a “whole-farm” dynamic model composed of 6 biophysical modules and a management system (Vayssières et al, 2009). This simulation model gives accurate predictions for various sustainability indicators (labor, energy consumption, production, nitrogen leaks to the...

Livestock supply must challenge the growth of final demand in the developing countries. This challenge has to take into account its ecological effects since the dairy and livestock sectors are clearly pointed out as human activities which contribute significantly to environmental deterioration....

Grâce aux avancées méthodologiques sur la prise en compte des outputs indésirables dans la modélisation des technologies de production, cet article permet d’évaluer l’éco-efficience de 51 exploitations laitières de La Réunion selon le point de vue de trois acteurs : l’éleveur, la...

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,...

In a recent article, Briec, Kerstens and Vanden Eeckaut (2004) develop a series of nonparametric, deterministic non-convex technologies integrating traditional returns to scale assumptions into the non-convex FDH model. They show, among other things, how the traditional technical input...

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...
