Welfare

Dear all,

I just started to used Dynare so I apoligize for my silly questions…
I am trying to replicate the EHL (2000) model in the version elaborated by Gali (2008).
Namely, I want to perform some evaluation of alternative monetary policy rules, and obtain the results in the form of welfare losses with respect to steady state consumption. Is it possible to write down welfare losses as a function of the variance of price inflation, wage inflation and the output gap, as it is done in the book?

You can read out the required variance along the lines of
[Simulated moments)
and
[Welfare cost of business cycles)
