This study estimates productivity gains and their distribution among inputs and outputs for American industries over the period 1987-2011 using the traditional surplus accounting method. Total Factor Productivity (TFP) change is traditionally defined as the growth rate of output minus the growth...

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 this paper, the Free Coordination Hull (FCH) approach developed by Green and Cook (2004) is combined with the Free Disposal Hull (FDH) model to detect potential gains from specialization. As a non-convex approach that allows both directly observed and summed decision making units (DMUs) to...

We focus on a simple framework on wheat producer behaviour in a context of price output uncertainty. More precisely, we establish a relationship between ex post output price level and allocative inefficiency that allows to characterize farmers’ risk preferences. Given this analysis, the...

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...

Policy makers as well as land users in developed countries are willing to promote new agricultural practices that are more environmentally friendly. This can be possible notably among several others by reducing chemical utilization. For instance in France, the agreement of the “Grenelle de...

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...
