Dynare forums

Dear users,

I am struggeling with a mod-file.

First of all, I use Dynare 4 on a MacBook with Mac OS X 10.5.6 and MATLAB 7.4.0 (R2007a) Student Version.

I installed Dynare, using the instructions of Christophe Cahn (http://www.christophecahn.me/?p=12). And I ensured that in MATLAB I set path to "/Applications/dynare/" and all its subdirectories.

I tried the "example.mod" (that came with Dynare) and everything went perfectly right. Within 1 minute MATLAB produced results including a figure. Then I tried another mod-file from a lecture called "new_perspectives.mod". This file run on the instructors Windows machine absolute correctly, but failed to run on my machine. (Note that I tried to run the mod-file from the same directory as the "example.mod".)

I will state the error message below and attache the mod-file. Has anybody an idea, what went wrong?

Many thanks in advance,
Emanuel

Hi

The error message at the end (the one which begins with "ERROR:") means that in your mod file,
at line 43, between columns 0 and 16, you are using "n" as a parameter, while it is not a parameter...

Indeed at line 43 you are trying to assign a value to "n", which is an endogenous variable. Such initialization are only allowed for parameters (or for strictly Matlab variables, not used in the model).
