Dynare forums

Hello,

I am trying to estimate the Gali & Monacelli, NBER w.p. 8905 model using CPI data from Fred, but I keep getting these errors(see below). I have read the forms, but I had no luck resolving the issue. If someone could be so kind to point me in the right direction it would be greatly appreciated.
Thank you in advance.

Regards,
Richard

Hello,

Here is the data file I am using.

Hello,

I have read more of the forums to try to solve my problem, and modified the original code to match some of these posting. But, I am still not able to get it to work. Any help would be appreciated.

Regards,
Richard

There are several issues. A general one is that you are not taking the parameter dependence in steady state into account. Please take a look at 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. You are performing a fundamental mistake by having lambda depend on estimated parameters and not using either model local variables or a steady_state_model-block to update lambda when beta changes.

Moreover, your data and the model are inconsistent. The model assumes a zero inflation steady state while your CPI is ever increasing. Use demeaned growth rates for the CPI as your observed variable. Again, refer to my Guide to Observation equations.

Hello,
I have the same kind of error.
Could you help me? Maybe, could I try to change some parameters?
But, what? And, how much? Is there a command to have this kind of answers?

Or, Would it be better to increase the number of observed variables (increasing also the number of shocks)?

Thank you so much,
Regards,
Chiara

Sorry, but the data file is missing.

Sorry, I upload immediately.
I have cleaned SMETS & WOUTERS data (2007) according to my single observable variable.

There must be a timing error in your model. Please put

Code: Select all

check;

after the shocks-block and then try to find the mistake that makes the indeterminacy problem in the calibrated model go away.
