Analysis of patent citations is a core methodology in the study of knowledge diffusion. However, citations made by patent examiners have not been separately reported, adding unknown noise to the data. We leverage a recent change in the reporting of patent data showing citations added by examiners. The magnitude is high: two-thirds of citations on the(More)
To what extent do firms go abroad to access technology available in other locations? This paper examines whether and when state technical capabilities attract foreign investment in manufacturing from 1987-1993. We find that on average state R&D intensity does not attract foreign direct investment. Most investing firms are in lower-tech industries and locate(More)
Researchers studying innovation increasingly use indicators based on patent citations. However, it is well known that not all citations originate from applicants— patent examiners contribute to citations listed in issued patents—and that this could complicate interpretation of findings in this literature. In 2001 the US Patent and Trademark Office (USPTO)(More)
Learning processes lie at the heart of our understanding of how firms build capabilities to generate and sustain competitive advantage: learning by doing, learning by exporting, learning from competitors, users, and alliance partners. In this paper we focus attention on another locus of learning that has received less attention from academics despite(More)
We explore the impact of geographically bounded, intra-firm linkages (internal agglomerations) and geographically bounded, inter-firm linkages (external agglomerations) on firms’ location strategies. Using data from the Census Bureau’s Longitudinal Business Database, we analyze the locations of new establishments of biopharmaceutical firms in the U.S. in(More)
We explore the impact of geographically bounded intra-firm spillovers (internal agglomeration economies) and geographically bounded inter-firm spillovers (external agglomeration economies) on firms’ location strategies. Using data from the Census Bureau’s Longitudinal Business Database and the U.S. Cluster Mapping Project, we analyze organic expansions of(More)
This study looks at the role of internal linkages in highly competitive clusters. Besides serving as a mechanism to source knowledge, we argue that strong internal linkages also represent tighter control over local innovation and higher levels of technological interdependency across locations, which allow firms to increase internalization and reduce the(More)
Geographically concentrated industry activity creates pools of skilled labor and specialized suppliers, and increases opportunities for knowledge spillovers. The strategic value of these agglomeration economies may vary by firm, depending upon the relative value of each economy, and upon firm and agglomeration economy traits. To better determine when a firm(More)
