hi everyone, I’m attempting to replicate the IRFs in the [Debortoli and Gali](https://www.nber.org/system/files/chapters/c14991/c14991.pdf) paper (Figure 11). However, even I tried the original equilibrium (instead of log-linear forms), applied higher order and pruning command. I was still unable to reproduce the results as seen in the paper: 1. for the monetary policy shock, my results are consistently smaller than those reported by Debortoli and Gali’s 2. for the technology shock, my results display no kinks/turning points. What could be the reason for the discrepency between my results and the correct ones? Is it possible that because I do not include the wage markup? (However, if I include the wage markup in the model, I can not solve the problem or have the indeterminacy problem.) I have attached the codes for TANK models. Thank you very much for your help!
