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.
Thank you professor, I really appreciate your reply~ your memory is really good hahaha!
I would like to further inquire about the result of my code running,

when this happens, what is the likely cause of the problem?
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?
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.
