The steadystate file did not compute the steady state

Cfarias · November 28, 2016, 8:41pm

Hi,

I’ve read other topics about this subject and i didn’t find a solution to my problem. So, when i try to compute the model i’m working on i get the following message from dynare:

The steady state equations are correct because when i compute separately it appears no error.

You need to be more careful. The last time I helped you write the steady state file, it was for a case where all variables are mean 0 and therefore the

NumberOfEndogenousVariables = M_.orig_endo_nbr; %auxiliary variables are set automatically for ii = 1:NumberOfEndogenousVariables varname = deblank(M_.endo_names(ii,:)); eval('ys(' int2str(ii) ') = ' varname ';']); end
part of the steady_state-file was not needed. Now you have a case where some variables are set in the steady_state-file. In that case, you need to use the above block and assign values to all endogenous variables

I put this block in the steady state file and i still get the following errors:

That tells you that your steady state does not match the entered equations. In one of the two, there must still be a mistake. Focus on the equations with a residual.

Cfarias · December 2, 2016, 11:58am

Thank you very much professor. Now I did worked.

Just one more question (maybe a silly one). As i wrote my model in the original form (not log-linearized), may i write the exogenous process in the following way?

ln(P_C) = (1 - rho_C)ln(Pss_C) + rho_Cln(P_C(-1)) + eps_C

or do i have to write in this way: ln(P_C) = rho_C*ln(P_C(-1)) + eps_C ?

The reason for that question is when i use the latter exogenous process and calibrate P_C at the steady state a value different from one, i get the same error as before. For the others exogenous processes, that is A_T, A_N, A_C i get no error. However, when i use the former one, the problem is solved.

jpfeifer · December 2, 2016, 8:13pm

The second one can only work if the steady state of P_C is 1. The other formulation is the actually correct one where the steady state of P_C is Pss_C

Hi…
That is make sense if I find all the value of my steady state variables to be zero? And what will be the implication.

Your model is linearized and therefore must have steady state 0, because in steady state, the deviation from steady state must be 0

eab · December 16, 2016, 5:34pm

Thank you very much Prof. Pfeifer for the clarification.

eab · January 12, 2017, 11:55am

If IRFs are not smooth is there any problem with it or with my model?

jpfeifer · January 17, 2017, 10:47am

What do you mean with

?

eab · February 7, 2017, 7:59am

What i meant was: The various IRFs show a zig-zag trend. The trajectories are not smooth.

jpfeifer · February 7, 2017, 5:57pm

If they oscillate this often indicates a timing error giving rise to a complex eigenvalue.

Bandel · January 2, 2023, 5:08pm

Dear Professor，
Dynare reports ”The steadystate file did not compute the steady state" when I solve my model.And the steady state value should be right but it still can not run.Could you help me~

jpfeifer · January 3, 2023, 4:36pm

You can see that there are big residuals in some equations, so either the entered equations or your steady state computations are wrong.

Bandel · January 3, 2023, 10:15pm

OK,I will try again.
And professor, can you recommend some robust methods to calculate the steady state of DSGE model?

jpfeifer · January 5, 2023, 11:43am

The only robust method is to carefully do the analytical computations.

Bandel · January 5, 2023, 1:34pm

Thank you professor!

Bandel · January 10, 2023, 12:43pm

Dear Professor,
I want to learn how to add other department such as innovation sector, real estate to DSGE.Could you recommend me some books or network resources~
The best wishes for you !

This seems like a case where you should use Google to find relevant articles.
