News about taxes and expectation-driven business cycles

Dear friends,

I am in a process of replicating the paper “News about taxes and expectation-driven business cycles” by Anca-Ioana Sirbu.
This is my first time using Dynare and I will be greatefull if you help me in this matter.
After creating this mod file and running model_diagnostics(M_,options_,oo_) it says that “MODEL_DIAGNOSTICS: No obvious problems with this mod-file were detected”. But “The steadystate file did not compute the steady state”. Also I am attaching the mod file that I created and the paper. Can You help me please to correct the code. ???

Best regards,
