Pollution-adjusted productivity change in french suckler cow farms: The use of a generalized multiplicatively complete färe-primont index
Résumé
The generalized multiplicatively complete Färe-Primont index is used here to assess pollution-adjusted total factor productivity (TFP) change and its components in French suckler cow farms. The results reveal that, when pollution (from greenhouse gases) is not considered in the model, productivity has stagnated over the whole period studied (1990 to 2013). Although some technological progress is recorded, it is totally offset by technical efficiency decrease. By contrast, there is a decrease in pollution-adjusted TFP, due to technological regress for more than one third, and to technical efficiency decrease for almost two third. This suggests that farmers did not have the right incentives to implement actions that would reduce such emissions during the period studied. An investigation of the characteristics of farms that have experienced an increase or stagnation of TFP vs. those that have recorded a decrease, indicates that rooms for improvement mainly relate to changing the feed system of the farms.
