I tried to run the Dynare code on this website: sites.google.com/site/pkaradi696/research, for the paper “A Model of Unconventional Monetary Policy,” kept getting this error code…

Starting Dynare (version 4.2.0).
Starting preprocessing of the model file …
ERROR: FA_model.mod:1.1: syntax error, unexpected $end
Error using dynare (line 126)
DYNARE: preprocessing failed

can you post the exact file? I don’t know why but I cannot open it from the website. Anyhow, my guess is that the problem is related to an “end” that is given twice. You know in Dynara you close each “section” with the end command, like:

model ;
…
…
…
end ;

shocks;
…
…
end ;

So somewhere (I think line 126) there is an “extra” end.

Thanks so much. But the codes are all in a zip file and the zip file consists of many files, so I can’t post all of them here. I can email them to you directly if that’s ok…

Here are my codes. I kept getting the following error message:
ERROR: GKRepApril27.mod:7.12-35: Symbol varphi declared twice with different types!
I ran my codes a few months and it worked. But now it’s not working. Appreciate your help! Thanks!

Hi,
I also tried to run this model in dynare. I am a completely greenhorn with dynare and for me it is really a mess with all these .m files.
I had a slightly different error message (maybe it depends on the different version):

*Starting Dynare (version 4.3.0).
Starting preprocessing of the model file …
ERROR: FA_model.mod:1.1: syntax error, unexpected $end

Error using dynare (line 114)

Which “end” did you have to kick out in order to run the model properly or did you take another solution? I already searched the “useless” end but I did not find it…
