Calculation of optimal initial values for a steady state

Hello! Can anyone help me to find the optimal initial values ​​for the steady state of my model? Or at least hint how to implement this, thanks

My model: first_variant.mod (15.4 KB)

No matter how strange it may seem now, but in this specification, the model is launched and everything is calculated, but this is only under the condition that the persistence of shocks is equal to 1…

Model: first_variant.mod (15.8 KB)

I can only recommend trying to compute the steady state analytically or to start from a smaller model. The steady state for the model with unit root shocks does not make any sense.
