Error on impulse responses!

Dear Dr Pfeifer,

I try to reproduce some results of News Shocks and Labor Market Dynamics in Matching Model (september 2014). The model contains a non-stationary TFP shocks, so I wrote the full set of detrended equations on dynare. The problem that the impulses response obtained does not match these one reported by authors (in paper and in the appendix).
Here is the link to the home page where you find the appendix and the paper. I joint codes on dynare. Is there any suggestion to solve this problem? … e/research

I am not familiar with the model, but if you have permanent TFP shocks, you might have to integrate the trend back in. See
