MIRAGE, a Computable General Equilibrium Model for Trade Policy Analysis

MIRAGE is a multi-region, multi-sector computable general equilibrium model, devoted to trade policy analysis. It incorporates imperfect competition, product differentiation by variety and by quality, 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 and to market structure changes. MIRAGE draws upon a very detailed measure of trade barriers and of their evolution under given hypotheses, thanks to the database MAcMaps. Simulations of a trade liberalisation between the European Union and its periphery illustrate the sensitivity to the main assumptions.
