Where do Personal Experience and Imitation Drive Choice?
This papers investigates the efficiency of aggregate choice in the long run when the individual decision is driven by both personal experience and imitation. Personal experience is represented by choice sets depending upon previous choices. Imitation is modeled first through popularity weighting and then through a network of social influences. Intuition suggests imitation can work as a source of variety, spreading behaviors among which memory can make selection. However inefficiencies will persist in the stochastically stable distribution whenever the length of memory is not sufficiently long to stop inferior behaviors from moving perpetually along periodic cycles of social influences.
