Peer Effects in Consideration and Preferences

This paper develops a general nonparametric model of discrete choice in which peers influence agents through two distinct channels: (1) the set of alternatives an agent considers (consideration set effects) and (2) the agent’s preferences over those alternatives (preference effects). The framework embeds these peer mechanisms in a continuous-time Markov process where agents revise choices at Poisson alarm-clock rates. A peer is classified as a consideration peer, a preference peer, or both, and the network is encoded as two directed edge sets rather than one.
