Analyse et mesure de l'incertitude en prevision d'un modele econometrique. Application au modele mini-DMS

This article describes the application to an operational medium-size econometric model, mini-DMS, of methods associating, to deterministic forecasts, a measure of the uncertainty due to the stochastic nature of behavioural equations. After having described the theoretical and practical foundations of the methods, we shal l analyze sequentially the deterministic bias, the uncertainty (standard error) of forecasts and of policy instruments, trying to look at the information from the point of view of the policy maker.
