Dynare forums

Hi,I am a new learner. When I try estimated a model ,dynare warned me the error:

There are 11 eigenvalue(s) larger than 1 in modulus
for 13 forward-looking variable(s)

The rank conditions ISN'T verified!


You did not declare endogenous variables after the estimation/calib_smoother command.

what should I do next? Thank you for your help.I attached my codes and data file here.

You have to fix your model for simulation first. That the Blanchard-Kahn conditions are violated suggests a timing error. The model_diagnostics provides a hint:

The following endogenous variables aren't present at the current period in the model:
var_epi

thank you for you advise. I will try it again.

by the way,where can I see the hint in the program?

I fix my program. There are still a problem.

There are 10 eigenvalue(s) larger than 1 in modulus

Typically, this is a timing issue. Check your model. As you are the only one knowing your model, the forum will not provide help here.

Given the size of your model, start from a stripped down easier version and make sure that one runs before expanding it again.

thank you very much. I have checked my model ,and solve this problem.

And another problem:

"Error using chol
Matrix must be positive definite."

I solove this problem by add "mode_compute=6". If someoneelse have the same problem, you can solve it like me . I write here to help somebody else.

Thank you for your help again, you do not know what a fave you do for me.

by the way,"The following endogenous variables aren't present at the current period in the model:
var_epi",how can you find this? by examing the model, or there is a way by DYNARE?

See the manual for

model_diagnostics

Hi,

I'm newer here. I have a problem with my code - I'm trying to write the code for chapter 3 of Gali 2008, but I'm having successful.
Here my problems:

I'm sending the code for anyone that want to help see and give me a hint.

Thanks a lot.

See Pfeifer(2013): "A Guide to Specifying Observation Equations for the Estimation of DSGE Models" https://sites.google.com/site/pfeiferecon/Pfeifer_2013_Observation_Equations.pdf, Remark 3 (Variable Naming in Matlab and Dynare).
The naming of the parameter with mu conflicts with Matlab. Also see https://sites.google.com/site/pfeiferecon/Gali2008_chapter3.mod

Thanks, Pfeiter. Your material is awesome, I will review in a good moment, as soon as possible.
Your hint works to me, the naming mu wasn't good and so I renamed to mi.
But I still have problems with B-K conditions. I organized better my equations, included more than Gali2008_chapter3.mod (also, I included more variables, as wages, prices and prices that "maximized the market value of profits..."as described in Gali (2008, 44) - pstar.

I think I am adding some no necessary equation in place of a really necessary equation, but I don't see what, and a better way is understand better what Matlab is saying with:

is not clear to me, where I have to look for?
I am attaching a new file again.

Thank you very much for your reply.

You cannot consider wages, money demand and prices.
The reason is that under an interest rate rule nominal prices are indeterminate. You can determine relative prices but not the nominal ones. Hence, you can determine the real wage (w-p) and real money balances (m-p) but not their individual components.
