Why my IRFs graphs are not smooth

[dsang]

Hello everyone, I constructed a DSGE model and try to study the IRFs graph. However, the graphs dynare produced based on my model is very strange, unlike smooth curves they are kinked. Is there anything I did wrong wit hthe model? I attached my mod. file below. Thank you for your help.

Did you upload the correct file? I get the message

ERROR: There are 35 equations but 36 endogenous variables!

See

Oscilating or alternating IRFs

It means that there is a complex eigenvalue leading to oscillations. Usually, when people have this problem in the forum, it comes from them ignoring the Dynare timing convention and then torturing the timing until the BK conditions are satisfied. When doing so, the correct economic timing is ignored and oscillating IRFs result.

Copy that. I will check it. Thank you, professor！
