Collaborative Networks as Determinants of Knowledge Diffusion Patterns

  title={Collaborative Networks as Determinants of Knowledge Diffusion Patterns},
  author={Jasjit Singh},
  journal={IO: Productivity},
This paper examines whether interpersonal networks help explain two widely documented patterns of knowledge diffusion: (1) geographic localization of knowledge flows, and (2) concentration of knowledge flows within firm boundaries. I measure knowledge flows using patent citation data, and employ a novel regression framework based on choice-based sampling to estimate the probability of knowledge flow between inventors of any two patents. As expected, intraregional and intrafirm knowledge flows… 
The Percolation of Knowledge across Space
A dynamic network formation model predicts Pareto-distributed innovator sizes, as well as an increasing relationship between an innovator's size and the distance at which it cites, and finds these two predictions to hold remarkably well in the data.
The geography of knowledge spillovers: The role of inventors’ mobility across firms and in space
Spatial concentration of knowledge flows is often brought up as a key source of increasing returns to location, and a major explanation for the clusterization of innovation activities. While
Organizational knowledge networks and local search: The role of intra‐organizational inventor networks
Using the collaborations among all knowledge workers in a firm, it is shown that those who have higher reach to all others and those who form bridges to connect unconnected groups of workers tend to leverage not only more organizational knowledge, but also knowledge that is more dispersed in the organization.
Mobility of Skilled Workers and Co-Invention Networks: An Anatomy of Localized Knowledge Flows
This article illustrates the contribution of mobile inventors and networks of inventors to the diffusion of knowledge across firms and within cities or states. It is based upon an original data set
Examining patterns of scientific knowledge diffusion based on knowledge cyber infrastructure: a multi-dimensional network approach
Results show that social capital factors such as collaboration experience, credibility, and similarity in career length positively affect knowledge diffusion and researchers’ activity level affects knowledge co-creation positively, but not knowledge transfer.
A relational approach to knowledge spillovers in biotech. Network structures as drivers of inter-organizational citation patterns
In this paper, we analyze the geography of knowledge spillovers in biotech by investigating the way in which knowledge ties are organized. Following a relational account on knowledge spillovers, we
Geographic Constraints on Knowledge Spillovers: Political Borders vs. Spatial Proximity
Geographic localization of knowledge spillovers is a central tenet in multiple streams of research. However, prior work has typically examined this phenomenon considering only one geographic
Mobility of inventors and the geography of knowledge spillovers. New evidence on US data
In this paper we exploit new data on US inventors in Organic Chemistry, Pharmaceuticals, and Biotechnology to revisit the JTH test of the localization of knowledge spillovers (Jaffe, Trajtenberg, and


Complexity, Networks and Knowledge Flow
It is argued that the degree of information inequality across social boundaries will reach its peak when moderately complex knowledge underlies these differences, and the idea that moderate knowledge complexity drives a wedge between the transfer of information internally and its diffusion across social borders is supported.
To understand the role of MNCs in international knowledge diffusion, two questions need to be considered: (1) How actively do overseas subsidiaries of an MNC exchange knowledge with other players in
Overcoming Local Search Through Alliances and Mobility
It is suggested that two mechanisms--alliances and the mobility of inventors--can serve as bridges to distant contexts and, thus, enable firms to overcome the constraints of contextually localized search.
Patent Citations and the Geography of Knowledge Spillovers: A Reassessment
Adam B. Jaffe, Manuel Trajtenberg, and Rebecca Henderson (1993) developed a matching method to study the geography of knowledge spillovers using patent citations, and found that knowledge spillovers
Do alliances promote knowledge flows
Gone But Not Forgotten: Labor Flows, Knowledge Spillovers, and Enduring Social Capital
It is well known that patent citations occur disproportionately between patents issued to inventors living in the same location, which has been taken as evidence of geographically localized knowledge
Do alliances promote knowledge flows ? July 2004 2
We explore the role of inter-firm alliances as a mechanism for sharing technological knowledge. We argue that knowledge flows between alliance partners will be greater than flows between pairs of
Localization of Knowledge and the Mobility of Engineers in Regional Networks
Knowledge, once generated, spills only imperfectly among firms and nations. We posit that since institutions and labor networks vary by region, there should be regional variations in the localization
Collaboration Networks, Structural Holes, and Innovation: A Longitudinal Study
To assess the effects of a firm's network of relations on innovation, this paper elaborates a theoretical framework that relates three aspects of a firm's ego network—direct ties, indirect ties, and
How Well Do Patent Citations Measure Flows of Technology? Evidence from French Innovation Surveys
Patent citation data are used in a growing body of economics and business research on technological diffusion. Research in this area uses “backward” citations to measure technological knowledge
