Your model is in logs, so it must be

PI = (P - P(-1));

When I run the model I get the steady-state but NaNs appear at theoretical moments.
I don’t know what this means!! does this cause problem?


Please provide the most recent version of the file.

here it is professor.

You can verify via


that these variables have a unit root so that the theoretical moments do not exist.
