First to Market is not Everything: an Analysis of Preferential Attachment with Fitness (0710.4982v1)
Published 26 Oct 2007 in math.PR and cs.SI
Abstract: In this paper, we provide a rigorous analysis of preferential attachment with fitness, a random graph model introduced by Bianconi and Barabasi. Depending on the shape of the fitness distribution, we observe three distinct phases: a first-mover-advantage phase, a fit-get-richer phase and an innovation-pays-off phase.
