Who's Who in Patents. A Bayesian approach

This paper proposes a bayesian methodology to treat the who's who problem arising in individual level data sets such as patent data. We assess the usefullness of this methodology on the set of all French inventors appearing on EPO applications from 1978 to 2003.Patents; homonymy; Bayes rule

The determinants of co-inventor tie formation: proximity and network dynamics

This paper investigates the determinants of co-inventor tie formation using micro-data on genomic patents from 1990 to 2006 in France. We consider in a single analysis the relational and proximity perspectives that are usually treated separately. In order to do so, we analyse the determinants of network ties that occur within existing components and between two distinct components (i.e. bridging ties). We test the argument that formation of these two different types of ties results from distinct strategies in accessing resources. Doing so, we contrast network and proximity determinants of network formation and we investigate if social network allows economic actors to cross over geographical, technological and organizational boundaries.Social networks, relational perspective, proximity, co-patenting, network formation

Social networks and innovation: concepts, tools and recent empirical contributions

JEL classification: A12, O31, Z13This paper reviews the most recent empirical literature dealing on social networks, knowledge diffusion and the innovative performance of firms. It aims to understand the extent to which the empirical literature on network and innovation addresses the key question of how social relations affect inter-firm knowledge flows. Reviewing the most recent and most significant empirical contributions in the field, we examine how social relations have been measured and defined and whether they affect inter-firm knowledge flows

The evolution of knowledge and trade networks in the global wine sector: a longitudinal study using social network analysis

Throughout the last two decades or so the global pattern of wine production has undergone fundamental changes. New players have emerged and technological and organizational changes have reshaped the way wine is produced and marketed. The aim of this study is to increase our understanding into these processes. We map and compare trade and knowledge networks using social network techniques in order to show how globalization has affected this particular sector, and how the main actors of this industry have responded to these challenges. We are able to give account of the structural changes that have characterised the industry at global level over more than three decades and relate them to the features of the main trade and knowledge blocks.trade network, knowledge network, social network analysis, wine sector

Proximity, network formation and inventive performance: in search of the proximity paradox

This paper investigates how network relations, proximity and their interplay affect collaboration and their inventive performance. Using patent citations as a proxy for patent quality, we investigate how the network and proximity characteristics of co-inventors enable them to access different sources of knowledge, in different geographical and organizational contexts, and finally affect the quality of inventive collaboration. Our findings enable to address the proximity paradox, which states that proximity facilitates collaboration and knowledge sharing, but it does not necessarily increase innovative performance, too much proximity may even harm innovation (Boschma and Frenken, 2009; Broekel and Boschma, 2011)

Research collaboration in co-­inventor networks: combining closure,bridging and proximities

This paper investigates the determinants of co-inventor tie formation using micro-data on genomic patents from 1990 to 2006 in France. In a single analysis, we consider the relational and proximity perspectives that are usually treated separately. In order to do so, we analyse various forms of proximity as alternative driving forces behind network ties that occur within existing components (i.e. closure ties) as well as those between two distinct components (i.e. bridging ties). In doing so, we contrast network and proximity determinants of network formation and we investigate to what extent social networks allow economic actors to cross over geographical, technological and organizational boundaries
