The agglomeration of R&D labs

Abstract: This paper has been superseded by WP 15-03. We study the location of more than 1,000 research and development (R&D) labs located in the Northeast corridor of the U.S. Using a variety of spatial econometric techniques, we find that these labs are substantially more concentrated in space than the underlying distribution of manufacturing activity. Ripley’s K-function tests over a variety of spatial scales reveal that the strongest evidence of concentration occurs at two discrete distances: one at about one-quarter of a mile and another at about 40 miles. We also find that R&D labs in some industries (e.g., chemicals, including drugs) are substantially more spatially concentrated than are R&D labs as a whole. ; Tests using local K-functions reveal several concentrations of R&D labs that appear to represent research clusters. We verify this conjecture using significance maximizing techniques (e.g., SATSCAN) that also address econometric issues related to “multiple testing” and spatial autocorrelation. ; We develop a new procedure for identifying clusters – the multiscale core-cluster approach, to identify labs that appear to be clustered at a variety of spatial scales. Locations in these clusters are often related to basic infrastructure such as access to major roads. There is significant variation in the industrial composition of labs across these clusters. ; The clusters we identify appear related to knowledge spillovers: Citations to patents previously obtained by inventors residing in clustered areas are significantly more localized than one would predict from a (control) sample of otherwise similar patents. ; This paper supersedes Working Papers 10-33 and 11-42.
