Hi everybody.

Guys, I really need you help. I have estimated VAR model on oil supply shocks. Now I would like to built impulse response functions (IRFs) and interpret them. However, these IRFs show me the response of a particular variable to the positive shock in oil supply, but I have to look at response to negative shock. For example, Eviews shows me that GDP increases if there is more oil produced (positive shock). But I would like to look at the reverse relation: decrease of GDP as a response to decrease in oil supply.

Does anybody know whether Eviews is able to do this or not?

P.S. I want to use Cholesky dof adjusted.

Just change the sign of your result.

I tried to change signs in Cholesky ordering, impulses, responses, but got the message "Error in specification of innovations or responses". Could you please explain more exlicitly where exactly I have to change sign?

I do understand what you have written before and now. I just wanted to get nicer picture... Thanks anyway.
