Help! generalized Schur (QZ) decomposition failed.

Postby GOODLUCK » Mon Dec 30, 2013 7:57 pm

Hello everyone,
I am greenhand on DYNARE. And the tool just stopped running by displaying error information starting with"The generalized Schur (QZ) decomposition failed. For more information, see the documentation for Lapack function dgges: info=47, n=47".Could anyone kindly help me find the reason or the solution? I've upload my .mod file below. I am apprieciated for your suggestions and help. Many thanks in advance. Happy New Year, by the way.

Please upgrade to Dynare 4.4, which would tell you
STEADY: numerical initial values or parameters incompatible with the following equations
27

Check whether your model in truly linear

Equation 27 should be
Code: Select all
theta_F*(1-nu_F_o)^2*M_ss*mu_P_ss*mu_P=alpha*A_o^alpha*k^(alpha-1)*n^(1-alpha)*pi_ss^2/(1+r_F_ss)*(A(+1)+(alpha-1)*k+(alpha-1)*A+(1-alpha)*n(+1))-(pi_ss-2*theta_F*(1-nu_F_o)*mu_P_ss*M_ss)*nu_F_o*nu_F(+1)-theta_F*(1-nu_F_o)^2*M_ss*mu_P_ss*M-(theta_F*(1-nu_F_o)^2*mu_P_ss*M_ss+nu_F_o*pi_ss)*r_F_ss/(1+r_F_ss)*r_F+(nu_F_o*pi_ss+2*theta_F*(1-nu_F_o)^2*mu_P_ss*M_ss)*pi(+1);                                                 

The part
Code: Select all
k^(alpha-1)*n^(1-alpha)

for example is clearly not linear in k and n.
