Welcome to the MIRAGE Wiki

MIRAGE is a multi-sector, multi-country Computable General Equilibrium model initially devoted to trade policy analysis and more recently applied to long term growth and environmental issues. It has been developed since 2001 by the CEPII. In 2007 the CEPII decided to create a consortium of institutions aiming at “fostering technical discussions around MIRAGE, extending its dissemination and maintaining its consistency and transparency”: the MIRAGE consortium.

Consortium’s membership includes CEPII and parties linked to it through 3-year bilateral conventions: IFPRI, ITC, UNECA, DG Enterprise and DG Trade at the European Commission… A Scientific Advisory Board (MIRAGE SAB) validates the new developments of the model.

On behalf of MIRAGE consortium, MIRAGE wiki is designed to provide up-to-date information on the model concerning its structure and its programmation features and aims to be a gateway for the dissemination of its policy applications. All members of MIRAGE Consortium are invited to contribute to this website.

For any information on the MIRAGE model or the MIRAGE Consortium, please contact MIRAGE information.

As a member of the Consortium, you can request a user account from the Webmaster. Consult the DokuWiki user's guide for information on using the wiki software.

If some useful information was missing or you encounter some bug, please contact the Webmaster by e-mail. The content of MIRAGE wiki will be enhanced accordingly.

The documentation is organized as follows:

• Structure overview
• Final demand
• The supply side
• Trade
• Imperfect competition
• Capital and investment dynamics
• Transport sector
• Macroeconomic closure
• Baseline
• Energy and GHG emissions

Before entering into the detail, the first entry can be:

• What is MIRAGE made of

Below is a step-by-step guide on how to conduct a simulation from start to finish:

1. Using GTAP aggregation (AggreGAMS) with MIRAGE-e
2. Other (optional) data preparation
3. How to parameterize MIRAGE-e
4. Running the baseline exercise
5. Running a simulation with GAMS
6. Managing results

MIRAGE-e, developed at CEPII since 2010, takes the core features of the MIRAGE model and put emphasis on longer term issues:

• Energy and CO2 emissions (1.1)
• Long-term Baseline (1.1) using output from the open source MaGE model
• Regular updates following the GTAP database

The documentation is organized as follows:

1. Structure overview (1.1)
2. Final demand (1.1)
3. The supply side (1.1)
4. Trade (1.1)
5. Imperfect competition (1.1)
6. Capital and investment dynamics (1.1)
7. Transport sector (1.1)
8. Macroeconomic closure (1.1)
9. Baseline (1.1)
10. Energy and CO2 emissions (1.1)
