SOE DSGE HELP!!

[roara]

Hi DSGE solvers

I'm trying make SOE DSGE model. But, I cannot solve NaN/Inf problem..
I need your advice that how can I fix this.

thank you,,

Please try a calibrated version of the model first. See Remark 2 (Using stoch_simul before Estimation) in 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.
Focus on equation 17 and the model-local variables involved in it. If I understand it correctly, you have

Code: Select all

#rsss=1/(ebs*beta);
#rlss=(rsss*ebs)/ebbarl;


But ebs is an exogenous variable that is mean 0, so you are dividing by 0 and rsss will be infinity. rlss then has infinity divided by infinity, resulting in NaN

Thank you very much, Proffessor !

I made a easy mistake. And, fixed this.
But, I have new problem that colinear variables/equations.

I read much Q's in this forum, but I don't get it well.
How can I fix this problem for example?


many thanks,

That is hard to tell. Usually, there is one equation missing that needs to replace one of the redundant equations entered in the mod-file. Alternatively, there may still be a (timing) error in your model equations.

Thank you for your quick reply!
I try to revise my equations.
Best wishes,
