If communication involves some transactions cost to both sender and recipient, what policy ensures that correct messages - those with positive social surplus - get sent? Filters block messages that harm recipients but benefit senders by more than transactions costs. Taxes can block positive...

We consider the mechanism design problem when agents' types are multidimensional and continuous, and their valuations are interdependent. If there are at least three agents whose types satisfy a weak correlation condition, then for any decision rule there exist balanced transfers that render...

This article develops a Bayesian persuasion model examining a manager's incentives to gather information when the manager can disseminate this information selectively to interested parties (“users”) and when the objectives of the manager and the users are not perfectly aligned. The model...

In Bayesian environments with private information, as described by the types of Harsanyi, how can types of agents be (statistically) disassociated from each other and how are such disassociations reflected in the agents’ knowledge structure? Conditions studied are (i) subjective independence...

When there is strategic complementarity and all agents have access to public information, but only a subset of them has access to private information, strategic complementarity within the subset of privately-informed agents enhances the focal power of public information. This results to an...

This article analyzes under which conditions a manager can motivate a junior worker by verbal communication, and explains why communication is often tied up with organizational choices as job enlargement and collaboration. Our model has two important features. First, the manager has more...
