Abstract

This paper introduces a two-stage model to extend the modeling of social influence in the context of sequential stated adaptation experiments, where an individual is requested to complete the same choice task twice, once before and once after knowing the choice of a social network member. The magnitude of social influence is made a function of individuals’ socio-demographics and the nature of the relationship with a certain social network member. To eliminate the influence of the structure of sequential experiments, two effects, labeled “choice consistency” and “similarity” are singled out. Choice consistency says individuals exhibit the tendency to make consistent choices in sequential choice tasks, while similarity says individuals are more likely to adopt the alternative chosen by the social network member if it shares a high degree of similarity with the one chosen by the individuals in the first stage. Choice of city trip itinerary is taken as an example to investigate the model validity. Results support the assumptions underlying the model.
