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 [[http://www.cepii.fr|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: [[http://www.ifpri.org/book-748/node/5075|IFPRI]], [[http://www.intracen.org/|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 [[mailto:info@mirage-model.eu|MIRAGE information]].

As a member of the Consortium, you can request a user account from the [[mailto:webmaster@mirage-model.eu|Webmaster]]. Consult the [[wiki:welcome|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 [[mailto:webmaster@mirage-model.eu|Webmaster]] by e-mail. The content of MIRAGE wiki will be enhanced accordingly.
