MIRAGE is a multi-region, multi-sector computable general equilibrium model, devoted to trade policy analysis. It incorporates imperfect competition, horizontal and vertical product differentiation, and foreign direct investment, in a sequential dynamic set-up where installed capital is assumed to be immobile. Adjustment inertia is linked to capital stock reallocation. MIRAGE draws upon a very detailed measure of trade barriers and of their evolution under given hypotheses, thanks to the MAcMap database. The most recent version, presented in this paper, offers improvements in the modelling of agriculture policy and dynamics.
