The econometric estimation of zero censored demand system faces major difficulties. The virtual price approach pioneered by Lee and Pitt (1986) in an econometric framework is theoretically consistent but empirically feasible only for homothetic demand system. It may even fail to converge...

[paper in French] The stabilization of agricultural markets and incomes is, with the support of farm income, one of the initial objectives of the Common Agricultural Policy (CAP). These two objectives have long been reached simultaneously thanks to price support mechanisms. However, the...

This poster presents a random parameter multicrop production choice models and its parameter estimates with a panel data set of 111 French crop producers from 2004 to 2007

With the Green Deal roadmap, the European Union aims to half the uses and risks of pesticides by the end of this decade. The European Commission (EC) claims that the proposal for pesticides will not disrupt European agri-food production and price. The EC argues that previous assessments of the...

The various assessments of the effects of a liberalization of world sugar markets are inconsistent with each other. One cause seems to be the modeling of the EU supply response. We investigate three possible linkages between sugar production under quota and the out-of-quota or "C" sugar supply:...

The European Union decided in June 2003 a new reform of its farm policy with a new step toward the decoupling of farm income support instruments. Available impact studies find that this reform will reduce production incentives, substantially for beef and to a lesser extent for arable crops. All...

In relation to the growing debate around multifunctionality, this paper attempts to classify alternative measures of agricultural income support according to their ability in achieving three policy objectives (supporting agricultural income, promoting positive externalities and reducing negative...

Recent reforms of agricultural policies in developed countries introduced direct payments to the detriment of traditional production enhancing instruments. Whereas these new instruments can influence production through several effects, current empirical studies do not show any significant impact...
