Claussen, Jörg; Falck, Oliver; Grohsjean, Thorsten (2012): The strength of direct ties: Evidence from the electronic game industry. In: International Journal of Industrial Organization, Vol. 30, No. 2: pp. 223-230

We analyze the economic effects of a developer’s connectedness in the electronic game industry. Knowledge spillovers between developers are likely to be of special relevance in this knowledge-intensive and regionally concentrated industry. We calculate social network measures for a developer’s connectedness to other developers at multiple points in time. In a regression in which we exploit within-career variation in social network measures, we find that the number of direct ties a developer has to other developers has a strong effect on both a game’s revenues and critics’ scores. The quality of indirect ties makes no additional contribution to the game’s success.
