Dear all,
I am totally new with Dynare and I am trying to replicate in Dynare the DSGE model of Uribe (2018) from this article: Uribe (2019), The NeoFisher Effect, Econometric Evidence from Empirical and Optimizing Model.pdf (326.7 KB). I reported the parameter values (p.3334) as my starting values and I manage to complete my model block and my initval block. The problem is when I run the resid(1) command for the residuals of the static equations, one equation is not equal to zero. Maybe I have an error in my model block, but I can’t find it. I don’t know if it’s because of this but my results when i run the stoch_simul are far from Uribe (2019). Can you help me with this?

Thanks
Hello everyone,
I still have the same problem, I search in this forum and in the Dynare manual but could not find an answer.
Can anyone could help me with this?
Best regards
To aid debugging, I would suggest to make use of Dynare’s \LaTeXcapabilties and tagging the equations to see what you implemented.
Hi,
First of all thank you for your answer. With the use of the Latex command and with a steady state file I managed to solve my first problem (all resid(1) = 0 now and the steady state looks good).
However, my results (IRFs and variance decomposition) are still differents from Uribe (p.3738). I suspect errors in my shocks block since the direction of the IRFs is good but not the magnitude (see pictures) . I tried the relative_irf option without success. Do you have any idea what could be the problem?

You need to define auxiliary variables for:
 log output (to consider percent deviations)
 the annualized interest rate instead of the quarterly one
Hello professor,
thank you again for your help. I just want to clarify exactely what I need to do for each point.

I search in this forum for auxiliary variables to consider percent deviations and I found two way to do this. The first one is to do yhat = log(y) (as in https://github.com/JohannesPfeifer/DSGE_mod/blob/master/RBC_baseline/RBC_baseline.mod) and add yhat to my stoch simul.
The second method is to do yhat2 = log(y) log(steady_state(y)) (as in https://github.com/JohannesPfeifer/DSGE_mod/blob/master/Jermann_Quadrini_2012/Jermann_Quadrini_2012_RBC/Jermann_Quadrini_2012_RBC.mod) and add yhat2 to my stoch simul.
Wich one I should use?

For the interest rate and the inflation variables, to obtain the deviation from preshock level in percentage points per year should I only add auxiliary variables like: iratehat = irate * 4 and inflation = inflation * 4? Or should I do something more like: iratehat2 = log(irate) log(steady_state(irate)) * 4?
Finally I have some difficulties to implement the permanent interest shock. I need to insure that the initial shock increases the permanent component of the interest rate and inflation by 0.25 percent per quarter or 1 percent per year. Is there an easy way to do this in Dynare like the endval command in deterministic model?
Thank you again for your useful help!
