Occbin_estimation: BK conditions are not satisfied

[jpfeifer]

1. Does a normal OccBin simulation work in your model? If yes, you may not have correct set all the options for estimation.
2. Usually, the problem with periodic solutions is with the specification. See

Occbin: "increase maxit or check_ahead_periods" with very high maxit and check_ahead_periods

Part of the problem is a bug that will crash Occbin whenever something goes wrong. See Provide error handling to piece-wise linear Kalman filter (#1854) · Issues · Dynare / dynare · GitLab The other issue is your specification. You had occbin_constraints; name 'ELB'; bind iT - 1e-06*vr_s1*Ups < 0.001247663; relax iT - 1e-06*vr_s1*Ups > 0.001247663; end; So the ZLB exactly binding will fall between the two regimes, creating oscillations. Using % load OccBin occbin_constraints; name…
