I have a DSGE model with multiple shocks, two of which (called v_u and v_d) I allow to be correlated. When I do Bayesian IRFs, the responses if the endogenous variable to v_u incorporate effects of v_d as well because of the correlation. Is there some way to suppress that, so I can see the responses of the endogenous variables to v_u, holding v_d =0? I tried the irf_shocks = option, but that seems only to change what is reported, not the calculations. Thanks.
