Morphogenesis of Social Networks and Coexistence of Technologies
The aim of the article is to link the formation of influence networks with the long run coexistence of technologies. In the spirit of Plouraboue et al. (1998), we postulate that potential adopters of a technology are situated in a social network. In our model, initial relations are partly negative and all the expected utilities are revised in parallel. When we consider an exogenous network, the model can provide endlessly fluctuating opinions. Now, agents reallocate their relationships, reinforcing trust in agents whose opinion is close to their. As a result of this process, the network stabilizates in the long run, generating diversity in stable expected utilities.
