The Directorate for Science, Technology and Industry (STI) leads OECD research and policy work on knowledge-based sources of economic and social growth and, more specifically, on the translation of science and technology into innovation. It works in the subject areas of science, innovation, biotechnology, nanotechnology and industry, among others. OECD Science, Technology and Industry Working Papers cover this broad range of issues and consist of studies, both technical and analytical in nature, prepared by staff or outside consultants. It includes working papers, which are meant to share early knowledge and elicit feedback, and occasionally policy reports, which are officially declassified by an OECD Committee.
