Hi,
I am trying to replicate Sim and Wu “Evaluating Central Banks’ Tool Kit” paper. Before dealing with the OCCbin, I was hoping I could solve in dynare the model without the ZLB constraint. I solved the non-stochastic steady-state functions by hand and entered them in the steady_state.m file (see attached). I then entered the 50 equations as provided by the authors in model block.
My challenge is I keep getting several non-zero Residuals of the static equations. Any help would be greatly appreciated.paramfile_sm1.m (636 Bytes) sm.mod (14.5 KB) sm1_steadystate.m (3.5 KB)
Hi,
in Dynare 4.5.7 I get
ERROR: sm.mod: line 179, cols 1-1017: nSS has wrong type or was already used on the right-hand side. You cannot use it on the left-hand side of a pound ('#') expression
Hi Jpfeifer,
I have fixed all my steady state values and all 50 residuals of the static equations are zero or almost zero. But i still get the “The steady state file did not compute the steady state” error. Your help once again will be appreciated.
Please see attached files.

Your computation is too imprecise given the tolerance. Use
options_.dynatol.f=1e-4;
before steady to reduce it. After that, you will get a BK violation that is most probably due to a (timing) error in your model.
Hi Jpfeifer,
Thank you very much for your assistance so far. Your prompt responses have been very helpful to me. I have also resolved the BK violation.
I have yet another issue. I am trying to produce impulse responses for a negative Monetary policy shock with hit the economy in the 7th period (See Blue lines in the attached fig1 picture). After following your previous discussions on the use of “simult_” function. The impulse response I get clearly indicate I am not doing the right thing with the simult_ function. Please, are you able to help me with my current challenge? See attached files.paramfile_sm1.m (664 Bytes) smnl.mod (14.0 KB) smnl_steadystate.m (2.8 KB)
Where can I see the problem? I don’t know what you are expecting to get.
My impulse responses. For example output is decreasing with a negative policy rate shock.
That’s very hard to debug. Maybe you made a timing mistake when you fixed the BK error. I can only recommend rechecking all equations again.
Hi jpfeifer,
I checked my equations and there were some typos. The models works fine for now. Your comments have to very resourceful. Thank you.
