Agricultural, equilibrium models and WTO - For years, computable general equilibrium models have been extensively used for the promotion of the free trade ideology in international audiences and trade negotiations. Yet, presently, they totally ignore risk and mainly dynamic considerations. Thus, the strength of their conclusions can be challenged. After an overview of the models which have been in operation recently, the paper presents alternative specifications. They would explicitly incorporate risk and dynamics into the analysis, while keeping the multi- sectoral approach and market clearing conditions which constitutes the comparative advantage of these tools. Very different results are expected.
