The ripple effect: Citation chain reactions of a nobel prize

Abstract

This paper explores the possible citation chain reactions of a N obel P rize using the mathematician R obert J . Aumann as a case example. The results show that the award of the N obel P rize in 2005 affected not only the citations to his work, but also affected the citations to the references in his scientific oeuvre. The results indicate that the spillover effect is almost as powerful as the effect itself. We are consequently able to document a ripple effect in which the awarding of the N obel P rize ignites a citation chain reaction to A umann's scientific ouvre and to the references in its nearest citation network. The effect is discussed using innovation decision process theory as a point of departure to identify the factors that created a bandwagon effect leading to the reported observations.
