Dear all,

I built a two sector model and try to simulate the model under the deterministic case. The model run well under the stochastic case. However, perfect_foresight_solver always fail under various parameter specifications. The results show that,

"

There are 15 eigenvalue(s) larger than 1 in modulus

for 15 forward-looking variable(s)

The rank condition is verified.

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

Perfect foresight solution found.
