@jpfeifer @stepan-a @MaximeBouter thank you all for your responses. I have been working on the MXN model for 5 months and I am stuck… What would you recommend me to check? I believe the problem is not a drift? Is it the calibration? Or the model equations? Since the model has a steady state in Matlab and Uribe toolbox, I must have made a mistake somewhere… Any idea would be really appreciated.
Here is my earlier question where I explained the model and my problem.
