Replicating Smets-Wouters(2003)

Hello

I am trying the replicate Smets-Wouters(2003) paper.
I was first trying to solve the model for calibrated parameters before undertaking estimation. But I have already errors(below). Thank you in advance for anyone who will help me. Cyril

You have equations like

c_f = (1/(1+hab))*(hab*c_f(-1)+c_f(+1))-((1-hab)/((1+hab)*sig_c))*(r-pie(+1))+ (1-hab)/((1+hab)*sig_c);

At the end you have a constant term

(1-hab)/((1+hab)*sig_c)

Given this term, your steady states cannot be 0. My guess is that you need to drop all constants.

Thank you Professor Pfeifer.
I am trying your suggestion.
