On March 27-28, 2012, the American Association for the Advancement of Science (AAA) will host the “International Symposium on Assessing the Economic Impact of Nanotechnology.” The Working Party on Nanotechnology (WPN) of the Organization for Economic Cooperation and Development (OECD), in collaboration with the U.S. National Nanotechnology Initiative (NNI), organized the Symposium. Lynn L. Bergeson is on the Steering Committee and will speak at the Symposium. The objective of the Symposium is to explore systematically “the need for and development of a methodology to assess the economic impact of nanotechnology across whole economies, factoring in many sectors and types of impact, including new and replacement products and materials, markets for raw materials, intermediate and final goods, and employment and other economic impacts.” Participants will address the scope of economic impacts of nanotechnology; input and output factors; metrics for other technological assessments; consideration of the appropriateness of these metrics for nanotechnology materials and products; the role of research funding portfolios; intellectual property frameworks; venture capital; public-private partnerships; state and local initiatives; international cooperation; and metrics such as private sector and industry investments, patents and publications, and the development of a technologically-educated workforce as metrics for nanotechnology. Attendees are being invited from a broad spectrum of backgrounds and expertise, including technology leaders, key decision makers, economists, investors, policy analysts, scientists and engineers from industry, business, government, academia, and the general public. Registration will open February 10, 2012, and will be on a first-come, first-served basis until the capacity is met. Positions are expected to fill quickly.
