Diffusion in Social Networks with Competing Products [article]

Krzysztof R. Apt, Evangelos Markakis
2012 arXiv   pre-print
We introduce a new threshold model of social networks, in which the nodes influenced by their neighbours can adopt one out of several alternatives.  ...  We show that the problem of determining whether a given node has to adopt some (resp. a given) product in all final networks is co-NP-complete.  ...  Acknowledgement We would like to thank Berthold Vöcking for suggesting to us the first two problems in Section 6.  ...

An Agent-Based Competitive Product Diffusion Model for the Estimation and Sensitivity Analysis of Social Network Structure and Purchase Time Distribution

Keeheon Lee, Shintae Kim, Chang Ouk Kim, Taeho Park
2013 Journal of Artificial Societies and Social Simulation  
The diffusion dynamics of competing products emerge from the aggregation of consumers' decisions.  ...  To maximise the possibility of success for a new product and minimise the risk and opportunity cost of a failed product, firms must understand the diffusion dynamics of competing products.  ...  To test the performance of the model, we applied the model to the diffusion of netbook products competing in the online market in Korea.  ...
