Dynare forums

HI,

I am a beginner of dynare.
my model raised an error which were posted many times in our forum:

??? Error using ==> print_info at 52
One of the eigenvalues is close to 0/0 (the absolute value of numerator and denominator is smaller than 1e-6)

>> model_diagnostics(M_,options_,oo_)
model_diagnostic: the Jacobian of the static model is singular
there is 4 colinear relationships between the variables and the equations

...
Relation 1
Colinear equations
1 5 13 18 19 44 46 47 48 49 50 62 65 75 76
....


my question is :

Where is the Colinear equations 1? Is it the first equation in the code?

Thanks very much,I am appreciated your generous help.

Could someone please help me? I would appreciate it.

In general, the equation numbers refer to equations as entered in your model-block. Things are a bit complicated by auxiliary variables and equations created in Dynare. How about posting your mod-file for me being able to look at it?

Thanks very much ,I have sent it to you. I doubt that the trouble may come from the newly added equations.

Hello jpfeifer I hope that I don't annoy you in fact I have the same problem (One of the eigenvalues is close to 0/0) when I tried to understand the problem with model diagnostics I have this message
This warning will become an error in future releases.

In fact I don't understand why dynare consider these equations colinear even I consider each one for two different countries seperately.Thank you for answering me

Most probably because they are interdependent via the current account.

Thank you for your answer yes you have reason .Sorry for the late
