my colleague is OK to distribute it under the GPL with (c) to DYNARE Team. For me it's the same for all other routines. In either cases, there will be something like csminwel1?

% Copyright (C) 1993-2007 Christopher Sims % Copyright (C) 2006-2011 Dynare Team
Where until 2011 the copyright is of the original author?
Here the two lines mean that we took the original file from Sims, and that we modified it; we added our copyright because Sims is not in Dynare Team.
For GSA, I think it makes more sense to have either only Dynare Team or only you as the copyright holder.
Both solutions are perfectly fine, as long as the license is GPL.
So I suggest to put your files as "Copyright Marco Ratto", and the one of your colleague "Copyright {his name}", all of them distributed under the GPL.
Do you want to adjust headers, or do you want to let me do it?
What about the documentation? My suggestion is "Copyright Marco Ratto", and licensed under the GFDL (GNU Free Documentation License).
We can also add some paper reference in the preamble if we think useful?
Sure, it is always useful to add more references. This is more of an informative nature; only the copyright information is legally binding.
