Hans Kwint writes "The European Commission's enterprise and industry department has just released the final draft of what could be the biggest academic interdisciplinary study on the economic / innovative impacts of free/libre/open source software (1.8-MB PDF). The study was done by an international consortium led by the United Nations University / University of Maastricht. The lead researcher, Rishab Aiyer Ghosh, has overseen a large volume of FLOSS studies in the last few years, including ones on FLOSS policies and worldwide FLOSS adoption. This academic-grade study has a very broad scope and has collected real-world information that is valuable for both companies and government bodies thinking about migration. The study is about the economic impact of FLOSS, not excluding the hidden indirect impact. It compares scenarios of open and proprietary software futures of Europe. The study looks at the FLOSS's competitiveness compared to proprietary software and also provides a few TCO comparison case-studies.
