How to construct a DSGE model with two steady states before and after a structural break

Steady state
1

Dear Johannes,
Thank you very much for your helpful guidance, I am grateful.
I have a question, we plan to construct a DSGE model given a structural break in 2020 Q1, the steady state prior to 2020 Q1 is different from the steady state on/after 2020 Q1, is there any type of model to capture this shift in steady state values due to a structural break?
Thank you very much and look forward to hearing from you.
Best regards,
Jesse

Without more context on what exactly you are trying to model, it’s hard to tell.
