I have tried to build a model based on a few equations from another model in which I have added some others.When I run my Dynare file, it seemed to be able to find the steady states,But I get some error messages from Dynare.

Error in print_info (line 54)

One of the eigenvalues is close to 0/0 (the absolute value of numerator and denominator is smaller than 1e-06!

If you believe that the model has a unique solution you can try to reduce the value of qz_zero_threshold.

Error in check (line 76)

print_info(info, 0, options);

Error in biyelunwen2 (line 314)

oo_.dr.eigval = check(M_,options_,oo_);

Error in dynare (line 235)

evalin(‘base’,fname) ;

When I use model_diagnostics(M_,options_,oo_),I encountered the error message below.

MODEL_DIAGNOSTICS: The presence of a singularity problem typically indicates that there is one redundant equation entered in the model block, while another non-redundant equation is missing.

But I couldn’t find which equation is redundant.

This is my modfile:biyelunwen2.mod (2.8 KB)

Thank you

Are you sure your steady state makes sense? How is

Y | 0.00595901 | |
---|---|---|

C | 12006.9 |

possible?

thank you.I will modify my model first.

Dear Professor jpfeier,I modify my model,but there are still some problems.This time,I can get the STEADY-STATE RESULTS(I think my steady state make sense this time),but Residuals of the static equations contain NAN and INF.I try to fix these equations,but failed.

Also,MODEL_DIAGNOSTICS: No obvious problems with this mod-file were detected.

Thanks again (2.8 KB)

Sorry, I don’t understand. The residuals are before steady state computation. As long as the steady state has been found and the file runs, there is nothing to worry.

Ok.Thank you again,Professor jpfeifer.
