OK, thanks. Looking at the
"simplest" model
(https://gennaro.zezza.it/software/eviews/glch03.php), there is no
econometrics involved, it is "just" about simulation. It would be
interesting to see whether the dynamic accounting relationships could be
specified in gretl's system block as (dynamic) identities. It's not
clear to me whether that is supported by gretl. (Also noting that the
doc in ch. 34 says that identities only matter for FIML estimation, so
another question is about their role in forecasting.)
let me also add the personal page of Alessandro Caiani. Under
/teaching/, you can find models written in R
https://sites.google.com/view/alessandro-caiani/home
Actually, while the first entry there is with R code, further down you
have Python codes and a Java-based toolkit (and also Mathematica, but
that is again closed source, of course).
My original point is that an SFC model at the end of the day is a
system of dynamic backward-looking equations (similar to a svar or a
reduced form DSGE model) . I think that Gretl in principle can handle
that as long as you have some numerical solver available. Of course,
you have to build your own program but it can be done.
Right. The relatively recent
addition of lpsolve support (linear
programming) might also be relevant here. (See Help / gretl + lpsolve).
