Dear community,
I am trying to solve a modified version of the model in Iacoviello (2005). In the model, I introduce a preference shock to drive the economy to ZLB. I am having problems with getting OccBin to work though. When I introduce a preference shock of 0.05 which should drive the economy to the ZLB, I get an error message saying:
“Occbin: Simulation did not converge – infinite loop of guess regimes”
When the shock is only 0.01 and the ZLB is not binding, the model is running smoothly.
I have also tried using a negative interest rate shock of -5 (eR in the code), here the ZLB is binding as expected. However, when trying with a positive interest rate shock of 5, OccBin is again returning the error message.
Could anyone potentially nudge me in the right direction as to where the error is? Please, find attached the execution file and the mod file.
Thank you in advance.
Best regards
Thomas Jensen
