The shape of Dynare figures

[Arwen]

Dear all, may anyone can help with my DSGE model
The figures to my models look very weird. Most of them have obvious angels like this

and this

The responses to some of the shocks are fine, i.e. the shape is beautiful and smooth
May anyone can tell me how to make my figures smooth ?
Does the problem come from my equations ? Or the linear equation is wrong ?
Please~ I will appreciate it you can help
Thank you very much

Irf is wired in the first periods?

There is no reason why an IRF cannot have a sharp turning point. It very much depends on the parameterization and the endogenous propagation mechanisms you put into the model. If you want to find out where it comes from, you need to simplify your by taking away features. At some point, the kink must go away.
