Dear all,
I am learning Dynare to solve DSGE problems. Now I am trying to use external Matlab file to compute steady state, with the help of the example “NK\_baseline\_steadystate.m”.
I have try my best to linearized the .m file. But the mod file failed to run with error message"Error using print\_info (line 90) The steady state contains NaN or Inf Error in steady (line 104) print\_info(info,options\_.noprint, options\_); Error in DynareStudystochastic (line 147) steady; Error in dynare (line 235) evalin(‘base’,fname) ;".
However, when I try to use the equations to compute steady state by another .m file, it works.
I have no idea what’s wrong with my ‘DynareStudystochastic.m’ file.
Could anyone here help me with that?[DynareStudystochastic\_seadystate.m](https://forum.dynare.org/uploa!%5BDynareStudy_model%7C387x500%5D(upload://aePwTPxzKwUHDFOdfHekVfWut8r.png)%20ds/default/original/2X/e/e1b4ef759ae5aa46ee4f1a741e2e4c8e096d34fc.m) (1.5 KB)

The model I am using is attached. Thanks!

You have a typo in the naming of the steady state file. If you do not obey the naming convention, Dynare will not be able to detect it.

Thank you Prof. Pfeifer! 😀
This mistake is stupid. haha

sorry to bother, may I ask how you resolved it?

`seadystate` must be `steadystate`.

For starters, you should initialize all variables.

Thanks for your reply, but I don’t quite understand. I assigned initial values to endogenous variables in the “initval” block. Do I need to assign initial values to all types of variables in the “initval” block?

You have 30 endogenous variables, but way fewer lines in `initval`.

What I think is that once the values of some endogenous variables are determined, the values of the remaining endogenous variables can be determined using the formula in the “model” block. I don’t know if this understanding is correct ?

No, Dynare takes initial values as the pure numbers you put in. It does not fill in the gaps from the `model`-block. After all, the model is a simultaneous equation system.

Thank you Professor. Based on the problem you pointed out, I have also assigned values to the remaining endogenous variables according to the equation in the “model” block. However, dynare is currently unable to calculate the steady-state value. Can you help me see where the problem lies?

None of the solvers seems to be able to find the steady state. Are you sure there is a unique steady state that can be computed analytically? Have you tried computing the steady state analytically? Often that is the only way to properly debug the model.
