"The steadystate file did not compute the steady state"

[jefbref]

I have written the steady state file of my .mod file and I received this message.

I followed the process described by the authors and I made sure that the tolerance limit is under e-10.

Is it sure that I have done some mistake computing it or could it be something else?

[jefbref]

I just used the option "solve_algo=2" of the steady command in my .mod file. I get 0 residuals for all my equations but I still get the same error "The steadystate file did not compute the steady state".

Is it normal to get 0 residuals for all my equations but still get that my steadystate file did not compute the steady state?

[jpfeifer]

No, it's not normal and usually happens if you do not set info correctly in the steady state file

[jefbref]

Thank you jpfeifer. I don't know what I have missed in my steadystate file, but I just copied the steady states of all my variables into my .mod and it worked.

I am having another problem now, I am trying to get the irf but I get the following error message:

Error using chol
Matrix must be square.
Error in irf (line 80)
VC_epschol = chol(VC_eps)';

I found on the forum that if I use two different but correlated shocks, Dynare performs a Cholesky decomposition. In my .mod file, I have several shocks but they are not correlated.

I looked into the error message, it seems that the matrix that is the source of problems is the covariance matrix of reduced-form residuals. Is my problem in my shocks declaration or could it be something else?

[jpfeifer]

Without the mod-file, one cannot tell.

[jefbref]

Sorry about that.

I don't know if it helps but I have noticed that if I use the "partial_information" option I can use the PCL_Part_info_irf.m instead of the irf.m in the stoch_simul.m file. I have tested it and I got the irf, but I still don't understand my mistake.

[jpfeifer]

Using Dynare 4.3.3

Code: Select all

stoch_simul(order=1, irf=20) Yz c Inv w H Re piCMR n bTot Rk kBar m mB dM;


works without problems.

[jefbref]

I wasn't using the 4.3.3 version, it is working now. Thank you jpfeifer.

Dear All,

I have model about interaction monetary and macroprudential policy, but when I execute the model, I get message error :

Loading 114 observations from data.xlsx


ESTIMATION_CHECKS: There was an error in computing the likelihood for initial parameter values.
ESTIMATION_CHECKS: You should try using the calibrated version of the model as starting values. To do
ESTIMATION_CHECKS: this, add an empty estimated_params_init-block with use_calibration option immediately before the estimation
ESTIMATION_CHECKS: command (and after the estimated_params-block so that it does not get overwritten):

I hope your help about my code and here I attached the mod.file. Thank you very much.

First off, never name your data-file "data"

The error message means that you have stochastic singularity, because there are more observables than shocks with non-zero variance.

[yuliaindrawati]

Thank you jpfeifer. I'll try again to run my model.

Greetings:

I am attempting to compute the steady state of a labor search model with monetary frictions. Given the complicated nature of the steady state, I use an external file. Specifically, the file analysis_392016 defines the parameter values and calls the mod file. The external steady state file OBC_DSCES_392016 runs the function roolz.m through nonlinear least squares to compute the steady state.

Unfortunately, I run into the error "The steadystate file did not compute the steady state." The residuals on static equations are as follows:

The static equations are zero, except for two equations, 15 and 16, which read:


Equation number 15 : -0.00046174
Equation number 16 : -6.5804e-05

This suggests a potential error, but with a mild TolFun should nevertheless meet the convergence criterion. Yet, this does not happen. I suspect there is some other problem. By the way, for some reason I get an error in the external steady state file assigning one of the parameters "eps" to a structure, i.e. param.eps=eps, and have to resort to directly assigning the number, param.eps=0.1. Not sure if this issue has any bearing on the primary problem.

Any help would be most appreciated!

First off:

WARNING: you are using a function (max, min, abs, sign) or an operator (<, >, <=, >=, ==, !=) which is unsuitable for a stochastic context; see the reference manual, section about "Expressions", for more details.

Second, your exitcode from the solver is

3
Change in the residual was less than the specified tolerance.

This does not mean you arrived at a solution and might explain the slight difference.

Third, eps is the Matlab command for the machine epsilon. You should never use it as a variable name (as is the case with i)
