Special Theme - Invited Paper


This article examines co-authorship networks of researchers publishing in Electronic Markets—The International Journal of Networked Business (EM). The authors visualize the co-authorship network and provide descriptive statistics regarding the degree to which researchers are embedded in the co-authorship network. They develop and test seven hypotheses associating the researchers’ embeddedness in the co-authorship network with the number of the researchers’ citations. Results indicate that author who publish co-authored articles in EM have their EM articles (whether co-authored or not) cited more frequently than those who publish EM articles only in their own names, and that the more they co-author the more they are cited because they are located in the center of a co-authorship network.
