Abstract: In this paper the authors show how potential output can be estimated and projected through an approach derived from the structural vector autoregression methodology. This approach is applied to the Mexican economy. To identify demand, supply and world oil shocks, the authors assume that demand shocks do not have a permanent effect on output and that the international price of oil is exogenous to the Mexican economy in the long term. They then calculate potential output by adding the world oil and supply components to the drift in output. They find that world oil shocks have been an important source of both actual and potential output fluctuations over a sample period extending from 1965 to 1994. However, they also find occurrences of important gaps between actual and potential output. Dans la presente etude, les auteurs montrent qu'il est possible d'estimer et de prevoir le niveau de production potentielle en utilisant une approche derivee de la methode structurelle d'autoregression vectorielle. Cette approche est appliquee dans la modelisation de l'economie mexicaine. Pour identifier les chocs de demande et d'offre et les chocs de prix mondiaux du petrole, les auteurs font l'hypothese que les chocs de demande n'ont pas d'effet permanent sur la production et que les cours mondiaux du petrole sont exogenes a l'economie mexicaine a long terme. Ils calculent la production potentielle en ajoutant les composantes des prix petroliers et de l'offre a la derive de la production. Les auteurs constatent que les chocs de prix mondiaux du petrole ont ete une cause importante de variations de la production observee et potentielle au cours de la periode 1965-1994, mais decouvrent egalement d'importants ecarts entre la production observee et potentielle.
