Unusual figures

[aliyeftn]

Can I consider this figures normal?

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.

Thank you.

I checked my model and did not find any timing issues, can I rely on it and make conclusion based on this model??

[jpfeifer]

No, there must be a mistake somewhere.
