Table 1: Mnemonics for the estimated models

models, together with the degrees of freedom as reported in the following scheme:

The possible restrictions are indicated by an arrow connecting the two boxes:
in particular, if a box connects model Mt
(U for unrestricted') to model Mh (R
for restricted), we say that model Mh is nested in model Mσ. Therefore, we
can test all the restrictions through a Likelihood Ratio test;15 in particular, if
we indicate by Ljy the log-likelihood of the unrestricted model and by the
log-likelihood of the model obtained after constraining some of the parameters,
the Likelihood Ratio test consists in calculating the statistic

2 ∙ (Lb - Lσ).

This statistic is asymptotically distributed as a where p is the number of pa-
rameters constrained in the restricted model. The results are reported in Table
3 and show that all the restrictions are refused at any conventional significance
level (90%, 95%, 99%). Clearly this procedure is not able to discriminate be-
tween two models that are not directly linked by a restriction, and therefore, we
cannot say whether U2 fits the data better than Si, since they are
non-nested.
Therefore, in order to select a model, we calculate two widely used criteria for
the comparison of non-nested models: the AIC (Akaike Information Criterion)
and the BIC (Bayesian Information Criterion, due to Schwarz, 1978); in both
cases the model maximizing the criterion is selected. The formulas are the
