Economic modelers or econometricians know that they have to control the accuracy of the computations, to get their results safe. Unfortunately, even if a few softwares allow to control it (especially in using an interval arithmetic), most of them are presented like black boxes, from an...

L'objet de ce papier n'est pas tant de présenter les principaux algorithmes utilisés en modélisation économique - nombre de manuels font des présentations de meilleure qualité et plus exhaustives - que d'en proposer une vision critique. Les modèles économiques, et plus particulièrement...

In this paper, we try to promote the building of a Quantitative Austrian Modelling (QAM). QAM must be viewed as a complementary quantitative prolongation of the Austrian methods and as a complementary approach to the already existing quantitative approaches - especially we would like here to...

The assumption we submit, because macroeconomic forcasts would be unperfect, is that behavioral equations doesn't enough describe economic behaviours through the capacity of reaction opposite to environment. Further, the forcaster belongs to his search-system, so that, may be, we must now...

The econometricians and the economic modelers have to know and use numerical analysis not only to have a good understanding of their results, but sometimes to built their own tools. The increasing tendency to the use of large-scale models leads the softwares to reach the limit of the saturation...

One can compare Econometrics with an Art which tries to minimize the lag between a quantitative law and a sample of data. Hence, the econometrics teaches us that before to built models, we must built data bank through strict procedures to prevent errors. Our paper presents classical methods to...
