A Replication and Extension of Goldenberg, Libai & Muller: A Complex Systems Look at the Underlying Process of Word-of-Mouth
ثبت نشده
چکیده
Goldenberg, Libai & Muller (2001) achieved two outcomes: empirical support for a fundamental theory of communications, known as the “strength of weak ties” (Granovetter 1973), and an explication of small-worlds simulations in marketing. Where Goldenberg et al found that weak-ties had as much or more effect on information dissemination than did strong ties, a near-exact replication, reported in this paper, found that weak-ties had less than one third of the influence of strong-ties. An exact replication and extension, to be presented at the conference and under review with the same journal as the Goldenberg study, leads us to be sceptical of the original findings.

We explore the effects of individualand network-level negative word-of-mouth on the firm’s profits using an agent-based model and specifically, an extended small world analysis. We include both permanent strong ties within the social network, and changing, often random, weak ties with other networks. The effect of negative word-of-mouth on the Net Present Value (NPV) of the firm was found to be...

This commentary builds on the paper by Goldenberg, Libai, and Muller (2009) and on the areas of the contribution it makes to the field: the distinction between word-of-mouth and network externality effects, agent-based simulations and extensions of the Bass model for aggregate models including word-of-mouth and network externalities. It reflects on some of the issues raised by this paper and pr...

Hence they fit well contagion processes amo...
