Identify the problematic equations by putting
resid;before steady. Then check these equations.
For example, your Taylor rule shows a problematic residual:
R=rhor*R(-1)+(1-rhor)*(phipi*pi+phiy*(y-y(-1)))+er;Basically, the constant seems to be missing. I think it should be along the lines of
R=rhor*R(-1)+(1-rhor)*(R_bar + phipi*pi+phiy*(y-y(-1)))+er;
