Smets&Wouters error

[sashe86]

Hi there,

I am trying to run the Smets and Wouters code which I downloaded from this site.

When i run the model, I get the following error;

Starting Dynare (version 4.2.5).
Starting preprocessing of the model file ...
ERROR: usmodel.mod:80.14: syntax error, unexpected ';', expecting EQUAL

??? Error using ==> dynare at 114
DYNARE: preprocessing failed

I've had a look through the code, but I'm not sure what needed to be amended?

Any ideas?

Check line 80, where the command ends. Or better, check if actually the command in line 79 ends with a ";"

Hi kyri82,

Yes, at line 80, there is a ';' - I have removed the ';' and re-ran the model and then get this error:

Starting Dynare (version 4.2.5).
Starting preprocessing of the model file ...
ERROR: usmodel.mod:84.8: syntax error, unexpected INT_NUMBER, expecting EQUAL

When I change it to an equal (which doesn't really make sense to me), I get this error:

tarting Dynare (version 4.2.5).
Starting preprocessing of the model file ...
ERROR: usmodel.mod:84.28: syntax error, unexpected EQUAL

??? Error using ==> dynare at 114
DYNARE: preprocessing failed

So, I wonder what it could be?

Can you send me the file? The original one, with the first error message.

The .mod file I'm using is attached.

Thanks for the help!

What does this command do? #usmodel_stst;
And why does it appear in the model block?

Any command in the model section of the form

#varname = expression ;

is a model local variable. Those are documented here: http://www.dynare.org/manual/index_15.h ... eclaration

Just delete that line since it isn't of the correct form in your file and then change the inv_gamma_pdf priors to inv_gamma2_pdf priors. The problem is that you are giving it values that it cannot use to solve for the hyperparameters. I did it in the attached file and it worked. You will next need a file for the data named usmodel_data. You didn't post that so I am not sure if you have it or from where to get it. It might be on whichever site you used to download the mod file.

@bkjecn,

Thanks, that solved the problem, really appreciate your help. Same to you @kyri82.

The original Smets/Wouters code was written for Dynare 3. What #usmodel_stst did is call a Matlab function that computed some of the parameters. You should not simply delete it. Note that there is a functioning version of the Smets/Wouters Model for Dynare 4 in the forum: http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=2588&p=5805#p5805

Hi jpfeifer ,

Just seeing your response now. I agree. It doesn't seem sensible to simple delete a line of code. I had a look at the functioning version of the SW model for Dynare 4 which you are referring to. Unfortunately, I seem to be getting an error when I run it:


Starting Dynare (version 4.2.5).

ERROR: usmodel_shock_decomp.mod:186.21-26: syntax error, unexpected NAME, expecting PARAMETER_SET

When I remove the line at 186 relating to the shock composition, I then get this error:

You did not declare endogenous variables after the estimation command.
This version of Dynare cannot estimate non linearized models!
