Deterministic simulation high frequency response at end of shock

[mhesam_ahmdn]

Hi everybody. I am doing some deterministic simulations and when the shock ends, high frequency responses are given for some variables. I want to ask if there is any possible way to get a smoother response without smoothing out the shock? I have posted an example below (the shock ends at period 32).

The shock code:

Thank you in advance.

Simplest NK model with capital (nonlinear)

There is nothing too unusual here. Your shock is a one-time one without persistence. It is well-known that in most rational expectations models most endogenous variables inherit the persistence of the exogenous process. That is the reason we add so many bells and whistles: to increase endogenous propagation.
