Impulse response figures not comming up

[stavakoli]

Hi,

I have a small-open-economy RBC model in which the response of government investment to oil price fluctuations is a key transmission mechanism and the government saves its oil revenue in a sovereign wealth fund.
I solve the model. I have a problem that the figure for impulse response not coming up.
I checked my codes several times but i did not find the answer.
Codes are in the attached file.

Attachment was too big to be load. So I wright codes here

Can you help me?

As the unstable version says:

stoch_simul:: The simulations conducted for generating IRFs to e were explosive.
stoch_simul:: No IRFs will be displayed. Either reduce the shock size,
stoch_simul:: use pruning, or set the approximation order to 1.

How can I solve the problem and what is the meaning of :
use pruning, or set the approximation order to 1

[jpfeifer]

Use

Code: Select all

stoch_simul(order=1);

or

Code: Select all

stoch_simul(pruning);

You may want to consider the manual.
