Hello Dynare Community,

I'm trying to replicate the model and results in Ferroni (2011) "Trend agnostic one-step estimation of DSGE Models" that appear in the section 1 (Introduction) based in Chang, Doh, and Schorfheide (2007). Since the model includes trends in the observed variables, I include two observation equations. But I'm having problems in the estimation as this results are shown along the identification command (I include the rest of the log file as attachment):

I tried writing the log-linearized model in Dynare, but the same problem and the same errors appear.

What could be the source of this? How can I solve it?

Thanks for your help!

PS: I couldn't upload the .xlsx file, please check my code and later I'll upload the file with observed variables

I will try to have a look, but things like this take longer as they are more complicated. Could you please upload everything in one zip-file. This allows attaching data.

Hi, here's the zip file.

Danke, Johannes!
