Modeling International Relationships in Applied General Equilibrium (MIRAGE)

Jump to: navigation, search
MIRAGE is a multi-sector, multi-country computable general equilibrium model initially devoted to analysis of trade policies, but more recently applied to long-term growth and environmental issues.

Approach

In the MIRAGE model, each sector is modeled as a representative firm, which combines value-added and intermediate consumption. The demand side is modeled through a representative consumer from each region that maximizes its utility function under its budget constraint. This unique agent, which includes households and government, saves a part of his income and the rest is spent on commodities. The CEPII is also developing an updated version of the model, called MIRAGE-e, which includes a more detailed description of energy consumption and CO2 emissions, as well as a new baseline scenario at the 2100 horizon.
