Error using print_info (line 32) The generalized Schur (QZ) decomposition failed

Stochastic simulations

Hi,

I’m getting a strange error when trying to run my mod.-file.

Error using print_info (line 32)
The generalized Schur (QZ) decomposition failed. For more information, see the documentation for Lapack
function dgges: info=29, n=27. You can also run model_diagnostics to get more information on what may
cause this problem.
Error in check (line 48)
print_info(info, 0, options);
Error in parsa.driver (line 568)
oo_.dr.eigval = check(M_,options_,oo_);
Error in dynare (line 293)
evalin(‘base’,[fname ‘.driver’]) ;

As I am new to Dynare the message gives me no kind of hint.
Some help would be appreciated.
Thanks in advance!

Check your timing, particularly the one for capital. See also Timing of capital in two sector economy

Thanks for the reply.
I will review the model again and announce the result.

I checked the model again and encountered the following error:

there are 13 eigenvalue(s) larger than 1 in modulus
for 15 forward-looking variable(s)

The rank condition ISN’T verified!

Error using print_info (line 32)
Blanchard & Kahn conditions are not satisfied: indeterminacy.
Error in stoch_simul (line 107)
print_info(info, options_.noprint, options_);
Error in parsa.driver (line 609)
[info, oo_, options_, M_] = stoch_simul(M_, options_, oo_, var_list_);
Error in dynare (line 293)
evalin(‘base’,[fname ‘.driver’]) ;

I HAVE CHECKED THE MODEL TIMING for several times and didn’t find any error.

“MODEL_DIAGNOSTICS: No obvious problems with this mod-file were detected.”

Pls Help!

Are you sure

//5//
L_F(+1)=rho_f*L_F+(1-rho_f)*(S_F+u);
//6//
L_I(+1)=rho_i*L_I+(1-rho_i)*(S_I+u);

is the correct timing?
