Hello everyone,
I am not sure if I understand the Figure 6 in the forward guidance puzzle by Del Negro et al (2017, version 9, but older versions also work) correctly. I guess one way to produce these impulse responses is to modify the sample code by professor Pfeifer (RBC_news_shock_model.mod).

I think that the zero quarters ahead panel of the figure should correspond to the unexpected policy shock, which is the \epsilon^R_t in their equation (6). Is that right?

The four and eight quarters ahead panels should correspond to the anticipated policy shock, which is the \sum^K_{k=1} \epsilon^R_{k,tk} in their equation with K=4 or 8. However, I am not sure if they are the responses to the eps_z_news shock or the “pure” news shock in the professor Pfeifer’s code.
Many thanks for any suggestions, hints or helps.
