Problem in ramsey policy

Dear all:

  I use dynare 4.4.2 to replicate table 2 in SGU2004JET 'optimal fiscal and monetary policy under sticky prices'. But the all the variables' theoretical moments are NaN, and there is a few differences between the dynare results and that in paper.  The attachment is the mod file,  where is wrong.  

Thank you.

I will try to look into this, but I will take some time. Or did you figure out the issue?
