Dynare forums

Hi everybody

I've been trying to estimate a DSGE model with Dynare but I keep getting the following error message:

Many thanks!!!

Hi,

One of the message lines says the rank condition is not verified.

Best regards,

Hi,

ur rank conditions r not satisfied, means u have to check either the timing of ur variables or the value of some parameters in ur model. Also, if u add the instruction "resid(1)" just before "steady" you'll see that too many equations have non-zero residuals, especially eq.7 showing a residual of 6.41 . Maybe you should try to change ur initial guesses in order to get residuals close to 0.

Hope this helps.

Hi,

Thanks for your advice.

I re-specified the model and now the model itself seems ok.


Again, thanks.
Kaz

//////////////////////////////////////////////////////////////////////////
i am running the similar model . my question is about parameter calibration
given the steady state equilbrium, (see in Christensen and Dib 2007), i find that if parameters(in the paper)--thet ,alpha ,S ,beta-,delta are calibrated. we can get the steady value of i/y. here is the problem . in the code attached , the steay value of i/y is also calibrated (maybe form data) and not consistent with other calibrated parameters. How to solve it?
i am a newbie. many thanks for your help

Kaz: Could you post the final codes, the ones that run?

Hi kwaner,

I don't keep the file. But, I remember I just gave soft touch to it.
Sorry.

Best,
Kaz
