MIRAGE is a multi-region, multi-sector computable general equilibrium (CGE) model, initially devoted to trade policy analysis and more recently applied to long-term growth and environmental issues. It incorporates energy, carbon pricing, imperfect competition, and rigid investment allocation, in a sequential dynamic setup where installed capital is assumed to be immobile. The model provides trade analysis with detailed treatment of trade costs and Armington specifications, drawing upon a detailed measure of trade barriers through the MAcMap-HS6 database. Production features nested CES functions with capital-energy bundles under both perfect and imperfect competition frameworks, while final demand follows a LES-CES utility function. The sequential dynamic framework enables longterm simulations by combining total factor productivity calibration with macroeconomic projections from the MaGE model. The most recent version offers significant improvements in electricity sector modeling with renewable energy representation, base-load and peak-load dinstinctions, and detailed greenhouse gas (GHG) emissions accounting with carbon market mechanisms. This documentation provides complete technical specifications, calibration procedures, and implementation guidelines for researchers and policymakers using MIRAGE for economic policy analysis.
