Dear Prof. Jpfeifer,
Professor, I have a problem with ramsey policy of second order approximation. I would very much appreciate any help I could get on this subject.
My situation is, my original basic model(not applying ramsey policy) is running well(every equation number =0).
And the steady state values for the lagrangian multipliers parameters are also correct.
My problem is, my original model is correct and ramsey parameters are correct, but after summing up these two parts, there are error messages like below.
----------------
Residuals of the static equations:
Equation number 1 : 0
......
Equation number 46 : 0
Equation number 47 : 0
Equation number 48 : -0.091696
Equation number 49 : 0
Equation number 50 : 0
Equation number 51 : 0
Equation number 52 : 0
Equation number 53 : 0
Equation number 54 : 0.5212
Equation number 55 : 0
Equation number 56 : 0
Equation number 57 : -0.089634
Equation number 58 : 0
Equation number 59 : 0
Equation number 60 : 0
Equation number 61 : -0.095088
Equation number 62 : 0
Equation number 63 : 0
Equation number 64 : -0.092314
Equation number 65 : 0
Equation number 66 : 0
.....
Equation number 75 : 0

**Impossible to find the steady state. Either the model doesn't have a steady state, there are an infinity of steady states, or the guess values**
are too far from the solution

I am not sure I had a wrong steady states values?
-
Or, I have heard sometimes Dynare can’t get the steady state for the ramsey policy technically, so I am wondering wheather my case is the one or not. If mine is this case, there is no way, I will give up.(so sad, I spent lots of time to reach this step)
-
Or if not, is there any solution to make all equation zero? because only 5 equations’ residuals are non zero, so i feel like I can fix it. If you knows the method or any suggestions, would you please let me know?
I look forward to hearing from you. Thank you so much Professor!
Best,
Esther
