NAN for theoretical moments by dynare 4.6.4s

The theoretical moment is NaN,but Simulation moment exists in the model。Why is there such a situation

From what I can see, the issue is a unit root that makes theoretical moments non-existent. You can check that many IRFs do not return to 0 after a shock.

Professor, what is the cause of the unit root? Can I continue to analyze my results?

I don’t know what the reason is. You need to carefully debug your model. Whether you can rely on your model depends on whether the unit root is a feature or a bug.

Professor, the endogenous variable of this model is the nominal value. Is this a reason for the unit root?

That may explain it due to the price level often having a unit root.

Because of the unit root of the price level, will it not affect the results of the analysis?

As long as you keep in mind that everything is nominal, no. But you may be mostly interested in the real variables.

ok,thank you!
