I am trying to find the path in a deterministic Ramsey planner problem. The steady state exists for the parameters that I use (I have found the steady state in maple which change for different values of the parameters). The following message appears:
There are 8 eigenvalue(s) larger than 1 in modulus
for 10 forward-looking variable(s)
The rank conditions ISN'T verified!
The results are:
Residuals of the static equations:
Equation number 1 : 0
Equation number 2 : 0
Equation number 3 : 0
Equation number 4 : 0
Equation number 5 : 0
Equation number 6 : 0
Equation number 7 : 0
Equation number 8 : 0
Equation number 9 : 0
Equation number 10 : 0
Equation number 11 : 0
Equation number 12 : 0

I have done everything suggested in similar posts, but nothing seems to work. Any answers, comments, clues will be kindly seen!!!
I attach the mod file.
