Stochastic simulation as a validation tool for econometric models

The complete validation of an econometric model is a process which involves a formidable number of activities in the various steps of model building, like economic structure specification, test of hypothesis and parameter estimation, simulation behaviour and decision making. Our attention will be mainly focussed on some aspects related to simulation and decision making; in particular, the purpose of this paper is to analyze some problems of the validation process for which stochastic simulation can be profitably used.
