You did not provide an initial values. Also, the steady states of the exogenous variables cannot be endogenously determined. You need to set them. A similar problem will appear for the interest rate. See

> You are confusing something. If collinearity arises after using the steady\_state operator, what you have done is exactly to remove the capability of the model to determine the steady state of that variable as a function of the parameters. Take again the example of the Fisher equation and steady state inflation. If you exogenously provide the steady state inflation pibar (which cannot be endogenously determined), you can endogenously compute the steady state nominal interest as the product of re…
