My quick question is related to the moments of a DSGE:
once I have estimated a standard DSGE model, I have the option to compare either the theoretical moments or the empirical moments (periods>0 in stoch simul).
What is the rationale for using either the theoretical or the empirical moments ?
Is there a sound reason why one should go for either case, given that they are different … or should the pragmatic reason prevail to use whichever fits best to the data ?
Many thanks in advance ?
