There are 5 eigenvalue(s) larger than 1 in modulus
for 4 forward-looking variable(s)

The rank conditions ISN’T verified!

Error using print_info (line 39)
Blanchard Kahn conditions are not satisfied: no stable equilibrium
How to solve this ? i am a newer.

Check your timing. In particular, if

is an Euler equation, the return to capital might be forward-looking.

Thanks very much! I have a try ,but it doesn’t work . would you like give me more help ?

4

As I said: check your timing. Only you know your model, so you are the only one who can do it. You must help yourself.

5

Thanks! but what principle shoud i follow when checking timing？

I have tried again and again ，but it always said Blanchard Kahn conditions are not satisfied

You have to correctly enter the variables with their respective timing as is standard in economics. Predetermined variables in Dynare must be entered using the end of period stock notation. Economic theory will precisely tell you what the correct timing for each variable is.
