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
