Observational learning is typically examined when agents have precise information about their position in the sequence of play. We present a model in which agents are uncertain about their positions. Agents sample the decisions of past individuals and receive a private signal about the state of...

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, an agent's payoff depends both on the state and...

We present a model of delegation with moral hazard. A principal delegates a decision to an agent, who affects the distribution of the state of the world by exerting costly and unobservable effort. The principal faces a trade-off between (i) granting the agent discretion, so he can adapt the...
