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! Angelos [model.mod](https://forum.dynare.org/uploads/default/original/2X/9/997820907d3c4feff0363080333fca67c8aaa2e6.mod) (1.87 KB) ---

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, Sung Ho [ex\_basic\_12.mod](https://forum.dynare.org/uploads/default/original/2X/c/c374dce738d911705965f56691c527a31df2ac6c.mod) (10.1 KB) ---
