Opening the black box of link formation: Social factors underlying the structure of the web

Sandra Gonzalez-Bailona (2009), Social networks

Links play a twofold role on the web: they open the channels through which users access information, and they determine the centrality of sites and their visibility. This paper adds two factors to the analysis of links that aim to draw a parallel between the web and other offline interorganisational networks: the resources that the organisations publishing online are able to mobilise, and the status or public recognition of those organisations. Exponential random graph models (ERGMs) are used to analyse a sample of the web of about one thousand sites, showing that both the economic resources of the producers of the sites (a proxy to their wider pool of resources) and their presence in traditional news media (a proxy to their status) significantly increase their probability of receiving more links, and therefore, their centrality. This adds a sociologically relevant dimension to the analysis of the web that has been disregarded so far but that is crucial to understand the way it distributes visibility.

Abstract

Links play a twofold role on the web: they open the channels through which users access information, and they determine the centrality of sites and their visibility. This paper adds two factors to the analysis of links that aim to draw a parallel between the web and other offline interorganisational networks: the resources that the organisations publishing online are able to mobilise, and the status or public recognition of those organisations. Exponential random graph models (ERGMs) are used to analyse a sample of the web of about one thousand sites, showing that both the economic resources of the producers of the sites (a proxy to their wider pool of resources) and their presence in traditional news media (a proxy to their status) significantly increase their probability of receiving more links, and therefore, their centrality. This adds a sociologically relevant dimension to the analysis of the web that has been disregarded so far but that is crucial to understand the way it distributes visibility.

Intraorganizational Networks, Interorganizational Networks, and the Impact of Central Inventors: A Longitudinal Study of Pharmaceutical Firms.

Srikanth Paruchuri (2009)Organization science, Published online before print January 22, 2009.

This paper proposes that a mechanism through which a firm’s location in the interorganizational network influences the firm’s internal innovation activities is modifying the amount of information flowing within the firm. Exploring a firm’s internal innovation activities, I hypothesized that structural centrality of an inventor in the intrafirm co-inventing network is associated with her impact on her firm’s innovation activities in an inverted-U-shape relation. I further hypothesized that this relationship is moderated by the firm’s centrality and span of structural holes in the interfirm network. I found strong support for these hypotheses in a longitudinal study of eight large pharmaceutical firms. The findings in this paper, apart from having managerial implications, have implications for research on alliances, network studies, and innovation processes.

Firm Scope Experience, Historic Multimarket Contact with Partners, Centrality, and the Relationship Between Structural Holes and Performance.

Andrew V. Shipilov (2009), Organization Science, January-February 2009; 20: 85 – 106.

This study investigates characteristics that affect the relationship between firms’ positions in a network of collaborative ties with other firms and their performance. Firms located in similarly structured networks rich in structural holes may obtain different performance results depending on their (1) capacity to absorb heterogeneous information, (2) ability to protect against partner noncooperation, and (3) bargaining power.
