Generalized schur (QZ) decomposition failed

Dynare help (legacy posts)

Hi,

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

[quote]Error using print_info (line 36)
The generalized Schur (QZ) decomposition failed. For more information, see the documentation for Lapack function
dgges: info=6, n=6

Error in check (line 76)
print_info(info, options.noprint);

Error in linearaak (line 176)
oo_.dr.eigval = check(M_,options_,oo_);

Error in dynare (line 120)
evalin(‘base’,fname) ;
[/quote]

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

You claim your model is linear, but in the equation

w=((1-alpha)*(k/n)^alpha*(a+alpha*k+alpha*n)-phil*n+phil*n(-1)+beta*phil*(n(+1)-n))/Wss;
k/n clearly is not linear.

Hi, I have the following error message.

Error using print_info (line 36)
The generalized Schur (QZ) decomposition failed. For more
information, see the documentation for Lapack function dgges:
info=30, n=28

Error in check (line 76)
print_info(info, options.noprint);

Error in ex_basic_12 (line 570)
check(M_,options_,oo_);

Error in dynare (line 120)
evalin(‘base’,fname) ;

I am wondering whether this message indicates parameterization error or equation error in the model.
Thank you.

Best regards,
