Hey Lau,
Agreed with Johannes; check my answer in the other thread for further specifics: Problems in finding the steady state
I’ve tried using an external file linked to dynare, but never got it working. Although it’s ideal, I’ve found that a good steady state file that just gives “correct” values works if you initialize dynare at that point. If you figure out how to link an external steady state file, I’d like to learn too!
