The generalized Schur (QZ) decomposition failed. For more information, see the documentation for Lapack function dgges: info=30, n=69. You can also run model_diagnostics to get more information on what may cause this problem

I have received the error message given above.
The code is given below.
I am new in dynare and I really appreciate your help.


I am getting an error message that the steady state cannot be computed. But equations like

log(z(+1)) = rhoz*log(z)+epsz(+1); % page 9(appendix), stochastic aggregate productivity level, following the autoregressive process (8)

clearly do not conform to Dynare’s timing convention.
