Econometrics Laboratory Software Archive (ELSA)
This site at UC Berkeley is partially funded by the NSF. It is
designed to " facilitate the interchange of computational
algorithms that have economic applications. In addition to serving
as a central location for experimental software, we want to work
with developers of algorithms, at Berkeley and elsewhere, to
produce standards for documentation and testing that will
facilitate the exchange of new methodologies and solutions to
complex computational problems. Authors of software that have
potential applicability in economics are encouraged to submit
algorithms that conform to our documentation and testing paradigm."
One unique aspect of ELSA is that where possible, code is tested,
so users have some assurance of quality. Researchers can easily
submit their code to the archive; they have detailed instructions
on how to do so. The archive also includes some data, and they
round out their collection with a section on "Manuals, FAQs, and
Working Papers" in the field.
