The main objective of this article is to examine econometric estimates of price elasticities of food trade functions. We investigate the relevance of the prominent gravity approach. This approach is based on the assumptions of symmetric, monotone, homothetic, Constant Elasticity of Substitution...

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...

The highly disputed effects of agricultural trade liberalisation are mostly simulated with static models. Our main objective in this paper is to evaluate the robustness of the static simulation results to the consistent modelling of dynamic behaviours and to the linked specification of...

[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

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...

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...

We revisit the question of choosing partial equilibrium or general equilibrium modeling in applied policy analysis in the context of evaluating the effects of a complete phase-out of the Common Agricultural Policy (CAP) of the European Union. We compare the results of three modelsï¾—two...

The main objective of the paper is related to the long standing issue of the econometric estimation of price elasticity of food trade functions. We investigate the relevance of the prominent gravity approach. This approach is based on the assumptions of symmetric, monotone, homothetic, CES...

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:...
