Welcome to the MIRAGE Wiki #

This website is under construction, moving away from its old plateform to a brand new one. If you need some information you can’t find yet, please contact mirage at cepii.fr. Thank you for your understanding!

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.

MIRAGE Users include CEPII and the following institutions: IFPRI, INRAE, ITC, UNECA, DG Enterprise and DG Trade at the European Commission.

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.

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

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.

MIRAGE Team at CEPII #

Since the built of the MIRAGE model, a team of economists constituting the Department of Trade Policy Modelling has been actively using the CGE for various studies, bringing through year technical improvements to the model.

The team is today composed of:

• Cecilia Bellora
• Houssein Guimbard
• Cristina Mitaritonna
• Leysa Maty Sall
• Yu Zheng

Analyses and papers benefit also from contributions by scientific advisors working closely with the team, in particular:

• Antoine Bouët
• Lionel Fontagné

Former members of the MIRAGE team at CEPII include: Mohamed Hedi Bchir, Yvan Decreux, Jean Fouré, Christophe Gouel, Jean-Louis Guérin, David Laborde, Maria Priscila Ramos, Sebastien Jean, Hugo Valin

MIRAGE team at IFPRI #

The International Food Policy Research Institute (IFPRI) has become one of the main users and developers of the MIRAGE model. Click here to see the recent developments and team members.

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 1.1 #

Technical Documentation #

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)
