Control by social influence: durables vs. non-durables

1 POLARIS - Performance analysis and optimization of LARge Infrastructures and Systems

Individual behavior such as the adoption of new products is influenced by taking account of others' actions. We study social influence in a heterogeneous population and analyze the behavior of the dynamic processes. We distinguish between two information regimes: (i) agents are influenced by the adoption ratio, (ii) agents are influenced by the usage history. We identify the stable equilibria and long-run frequencies of the dynamics. We then show that the two processes generate qualitatively different dynamics, leaving characteristic 'footprints'. In particular, (ii) favors more extreme outcomes than (i). This has direct implications for the control of policy interventions.
