I present a model of observational learning with payoff interdependence. Agents, ordered in a sequence, receive private … signals about an uncertain state of the world and sample previous actions. Unlike in standard models of observational learning … unbounded strength there is learning in a strong sense: agents' actions are ex-post optimal given both the state of the world …
