Simulation of the perfect foresight model failed!

Perfect foresight simulations
1

Hi,
I’m trying to learn how dynare modeling works. I use the Smets model (aatached above). I hope all equationsare written correctly. However I faced two problems: 1)Simulation of the perfect foresight model failed! 2)Failed to find a solution to the linear system. Are these problemes caused by random data I used? or they are caused by incorrect equations I typed.
I would appreciate your advices and solutions for these problems!
thank you.

The equation

pepsilon(+1) = prho + peta - pmup * peta(-1);

does not contain a constant term prho that should not be there.Your model is linearized, so all steady states should be 0.

I changed this equation, there was a mistake . What should I do to get a 0 steady states?
These model has another equation, that explains endogenous var y, but in that case ve have 19 var and 20 equations.

Delete the initval-block. All initial values must be 0. Once you do this, you will see that your model does not satisfy the BK conditions. So there must be a mistake somewhere.
