This paper studies the social value of public information in environments without common knowledge of the data-generating process. We show that the stronger the coordination motive behind agents' behaviour is, the more they use private or public signals in the way that they suspect others are...

We examine whether belief-based preferences - caring about what transgressors believe - play a crucial role in punishment decisions: Do punishers want to make sure that transgressors understand why they are being punished, and is this desire to affect beliefs often prioritized over distributive...

A central assumption of the canonical cheap talk literature is that people misreport their private information if this is to their material benefit. Recent evidence from laboratory experiments with student subjects suggests, however, that while many people do report the payoff-maximizing...

We consider a Bayesian persuasion problem where the persuader and the decision maker communicate through an imperfect channel that has a fixed and limited number of messages and is subject to exogenous noise. We provide an upper bound on the payoffs the persuader can secure by communicating...

We compare the optimal trading strategy of an informed speculator when he can trade ahead of incoming news (is "fast"), versus when he cannot (is "slow"). We find that speed matters: the fast speculator's trades account for a larger fraction of trading volume, and are more correlated with...

Mere observation of others' choices can be informative about product quality. This paper develops an individual-level dynamic model of observational learning, and applies it to a novel data set from the U.S. kidney market where transplant candidates on a waiting list sequentially decide whether...

Informational interventions have been shown to significantly change behavior across a variety of settings. Is that because they lead subjects to merely update beliefs in the right direction? Or, alternatively, is it to a large extent because they increase the salience of the decision they...
