about impulse response

[chenlili8315]

Hi, all:

When graphing the impulse response, how to set a positive shock or negative shock?
I have drawn the impulse responses before, it seems that the response of GDP to all monetary polices are rising in general, but the shock can be either positive or negative. Does the rats have the default value to make the a positive response all the time?

Thanks.
