thanks for answering me .my problem is that in the tfp shock irf .output can not return to the steady state and some variables also show this feature in IST shock.i want to know it is because of the fault of model or other reasons to produce this feature. thank you

All IRFs return, but it takes some time. Set
Code: Select all
stoch_simul(irf=1000);

to see this

It is not completely unusual. It very much depends on the frictions in the model and the parameterization.
