Hello everybody,
I need some advise for a problem with deterministic shocks. I am simulating a very basic NK model with no capital and rotemberg pricing. I am trying to reach the ZLB with a temporary shock to the discount factor. With a certain calibration I obtained complex simulated series, with others I get the error copied below. Does this happen for a mistake in my code (which I don’t find) or can it happen to have these problems with deterministic simulations?what should I do when facing this problems or in general also when I am told that the matrix is singular and I get no output?
Thank you for your reply
