GIRFs when using a stochastic extended path model


Dear all,

If you solve a model using the stochastic extended path, I understand that when the order is set to 0, then the model is simply solved using a perfect foresight algorithm. Then the IRFs would be identical to what you have in the deterministic case. (As

However, with higher order, there is uncertainty for the number of periods specified, hence there can be an interaction of the shocks similar to when solving the model using a higher order perturbation method. Then, should we calculate GIRFs that are different from the perfect foresight IRFs? Does simult_ work after using extended_path?

Thanks for clarifying,
