This week's speaker at the Gov 3009 workshop is Lee Fleming from Harvard Business School. He will be speaking on "Small Worlds Enhance Innovation." This will be the final meeting of the year. Abstract: We'll first describe our data set of the collaboration networks of 2.1 million inventors from the last 30 years. We'll then present a short paper that looks at the influence of small world networks and indirect ties upon regional productivity (ie., is Silicon Valley really different than Boston and does it matter). Finally, we'll sketch a preliminary research design for doing analysis at the individual inventor level and open it up to a discussion of the potential and problems at this level of analysis. This is joint work with Charles King III and Adam Juda. The paper is available at: http://www.courses.fas.harvard.edu/~gov3009/handouts/SmallWorldEnhanceInnov… Seminar Information: The seminar meets at noon in Room 22, Center for Basic Research in Social Sciences (CBRSS, 34 Kirkland St., this is the yellow building across the street from William James Hall).
