Abstract

Proposition 2 in Chandrasekhar et al. (2020) characterizes when imitation is optimal in a discrete-time setup where all agents are myopic Bayesian and this is common knowledge. In this note, we provide a correction to this result, where the condition for imitation to be optimal is stronger than in the original result.
