# Problem getting steady state values

Hello, I am trying to run the attatched dynare mod file and following matlab files for steady state. To get the steady state value, I used ‘fsolve’(‘solve_calibration.m’) while running ‘_steadystate.m’ file. I used the example code by JohannesPfeifer : “DSGE_mod/Gali_2010/Gali_2010_calib_target_steadystate.m at master · JohannesPfeifer/DSGE_mod · GitHub”. The ‘fsolve’ was done successfully(please refer to ‘_error.txt’) and I got my ‘deep parameters’ updated with no weird values. However, I got ‘The steadystate file did not compute the steady state’ message with the following result.

Residuals of the static equations:

I checked the equations for any typos or other mistakes but I could not find one. I would be really appreciated if anyone could help me handle the problem.

To add a short background, the model is a medium scale NK model(similar to NK baseline model but for labor market frictions and some policy structures). The labor market frictions come from Christiano et.al.(2016, Econometrica) and some notations(e.g. ump) from Ravenna and Walsh(2011). I did not make use of Omega as in Christiano et.al.(2016, Econometrica) for this prototype version.

Thank you so much.

Thank you for your comment. I now have the following result, which does not have NaN or Inf. However, some values on the residuals seem to be far from zero and it still shows ‘The steadystate file did not compute the steady state’. The result I see is as follows:

Thank you so much!

Now it’s a standard problem of steady state computations and model equations not matching. Debug your codes based on the equations with residuals.

Thank you so much for your help! I debugged my codes (changing some definitions at the mod file and equations on the steady state file as well as setting phif = 0 as in NK baseline.mod) and got the following result:

However, I still have a problem with a message that : “Error using print_info
Blanchard & Kahn conditions are not satisfied: indeterminacy.” (please refer to the “_error2.txt” attatched.)

It also says: “There are 19 eigenvalue(s) larger than 1 in modulus
for 20 forward-looking variable(s) The rank condition ISN’T verified!”

I attatched the updated .mod file and steadystate.m file. The _calibration.m file remains the same. Thank you for your help!! Your comments make my progress. Thank you.

This looks like a timing error. `ump` does not appear contemporaneously in the model.
