Scientific knowledge is believed to be the wellspring of innovation. Historically, firms have also invested in research … to fuel innovation and growth. In this paper, we document a shift away from scientific research by large corporations … innovation. Large firms appear to value the golden eggs of science (as reflected in patents) but not the golden goose itself (the …

This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the … conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data …, industrial diversity) that theoretical and empirical work link to innovation, and we discuss factors that help sustain these …

The rate of university patenting increased dramatically during the 1980s. To what extent did the knowledge flow patterns associated with public sector inventions change as university administrators and faculty seemingly became more commercially oriented? Using a Herfindahl-type measure of patent...

This paper is an attempt to assess the existence and magnitude of local research spillovers in France. We rely on the model of an extended production function (Cobb-Douglas and Translog) with both local and neighborhood Ramp;D capital stocks. We estimate this model on 312 employment areas as of...

The empirical analysis in quot;International Ramp;D Spilloversquot; (Coe and Helpman, 1995) is first revisited by applying modern panel cointegration estimation techniques to an expanded data set that we have constructed for the purpose of this study. The new estimates confirm the key results...

Are scientific knowledge flows embodied in individuals, or "in the air"? To answer this question, we measure the effect of labor mobility in a sample of 9,483 elite academic life scientists on the citation trajectories associated with individual articles (resp. patents) published (resp. granted)...

This paper studies how corporate research and development (R&D) investment affects labor mobility. We use employer-employee matched data in ordinary least squares and instrumental variables analyses to assess four hypotheses. R&D has no effect on worker retention, exit from employment, or...
