Use the steady_state operator. See e.g.

Exp() substitution with steady_state operator

Dear all, How do perform an exp() -substitution of gov rule correctly G/STEADY_STATE(G)=((G(-1)/STEADY_STATE(G))^(gammaG))((BPI*STEADY_STATE(Y)/(Y(-1)*STEADY_STATE(B))))^((1-gammaG)*phiG)*eps_G; I tried to: exp(G)/(STEADY_STATE(G))=((exp(G(-1))/STEADY_STATE(G))^(gammaG))((exp(B)exp(PI)(STEADY_STATE(Y))/(exp(Y(-1))(STEADY_STATE(B)))))^((1-gammaG)*phiG)*eps_G; I understand that the steady state of G is not log-linearized form, but could not figured out how to change it. Could you please give …
