Stylized Facts in the Geography of Innovation (2010, methodology): “The reassessment concludes that in principal the JTH methodology is capable of indentifying the localization of knowledge spillovers, but only if controls are carefully selected based on the suggested detailed technology subclass classification (Thompson and Fox-Kean, 2005).”
Innovation and the evolution of industries (2006, methodology): “The analyses by Jaffe and Trajtenberg (2002) and by Thompson and Fox-Kean (2005) show that patent citations are a noisy signal of the presence of spillovers, and that aggregate citations flows can be used as a proxy for knowledge spillover intensity.”
Do non‐competition agreements lead firms to pursue risky R&D projects? (2014, background): “In particular, I focused on patented inventions whose first inventor resides in a U.S. state; similar to prior work (Thompson, 2005), I assigned each patent to the state of residence of the first inventor.”
Patent citation data in social science research: Overview and best practices (2017, neutral): “In response, Henderson, Jaffe, and Trajtenberg (2005) agree that it is possible that finer technological controls might be appropriate, but they point out that slicing things too finely minimizes the possibility for identifying knowledge flows across subclasses.”
Spreading the Word: Geography, Policy and University Knowledge Diffusion (2010, background): “This concern was originally raised by Thompson and Fox-Keene (2005) in the context of the classic paper by Ja¤e, Trajtenberg and Henderson (1993).”
The knowledge spillover theory of entrepreneurship (2005, positive): “…by the historically developed stock of scientific-technological knowledge.2 In addition to facilitating technological change, knowledge also generates opportunities for third-party firms (Jaffe et al. 1993; Thompson and Fox-Kean 2005), which are often entrepreneurial start-ups (Shane 2001).”
Frontier Knowledge and Scientific Production: Evidence from the Collapse of International Science (2018, background): “Previous research has shown that city, state, and country borders are important barriers to knowledge ows, as measured by patent citations (e.g. Ja e et al., 1993; Thompson and Fox-Kean, 2005; Peri, 2005; Belenzon and Schankerman, 2013; Head et al., 2015).”
Gone but not Forgotten: Knowledge Flows, Labor Mobility, and Enduring Social Relationships (2006, positive): “4 Thompson and Fox-Kean (2005) recently proposed a method for enhancing the selection of control patents by matching on a primary and secondary six-digit classification rather than the three-digit primary classification of the citing patent.”
Breakthrough Inventions and Migrating Clusters of Innovation (2009, background): “…example, Arzaghi and Henderson (2008), Carlino et al. (2007), Carlino and Hunt (2007), Delgado et al. (2008, 2009), Ellison et al. (2009), Glaeser and Kerr (2009), Jacobs (1970), Ja¤e et al. (1993), Marshall (1920), Rosenthal and Strange (2003), Thompson (2006), and Thompson and Fox-Kean (2005).”
Local Industrial Conditions and Entrepreneurship: How Much of the Spatial Distribution Can We Explain? (2009, background): “…by any existing industry within city c, (4) will take its lowest possible value of negative two. in the transfer of ideas, and studies of patent citations highlight the importance of local proximity for scientific exchanges (e.g., Jaffe et al., 1993; Thompson and Fox-Kean, 2005; Thompson, 2006).”
Entrepreneurial practices in research-intensive and teaching-led universities (2016, background): “Related to this is the academic discourse on the economic and geographical dimensions of university–industry links, which tends to focus on tangible, easy to quantify, knowledge transfer mechanisms such as patenting, licensing and knowledge-intensive spinouts (Agrawal and Henderson 2002; Di Gregorio”
