Could you please advise how to write the steady-state equation for the formula in the image within the steady_state_model block? In the steady state, the terms lnYbar on both sides of the equality will cancel out. Waiting for your reply, thank you all.
\ln \bar Y_t-\ln \bar Y_{t-1} = (1-\rho)(g+n)+ \rho(\ln \bar Y_{t-1}-\ln \bar Y_{t-2})
I am not sure I understand. The equation clearly shows that Y_t grows by g+n per period. It does not have a steady state. That is why the equation is expressing in growth rates. The variable with a steady state is \Delta \ln Y with steady state g+n.
