Erratic Managed But ... Still an Econometric Anlysis - Discussion (in Italian) of the R.G. Avesani and G.M. Gallo paper

The conclusions that can be drawn from reading the article are not univocal. This is essentially due to the fact that the analysis made by Avesani and Gallo is of a preliminary nature. From one side, the use of parametric and non-parametric tests (among them, why the Authors do not use the autocorrelograms?) provide some behavioural characteristics of the stochastic processes underlying the series. However, the Authors do not provide any direct synthetic information such as the structural econometric models underlying these series. Probably this were outside the scope of the analysis, but that aspect should be considered for completing the research. In conclusion, it is possible to affirm, by paraphrasing the title of the article, that their work seems "well managed but ... not yet an econometric analysis".
