Small open economy model

Please I am trying to solve my Small Open Economy Model but the following message keep appearing, "Impossible to find the steady state. Either the model doesn’t have a steady state, there are an infinity of steady states, or the guess values are too far from the solution"
Kindly assist me on the way out.


There is no obvious advice, except for: recheck your model (use the resid-command as a guidance) and ideally, provide an analytical steady state.

Thank You.
