We consider a dynamic principal-agent problem, where the sole instrument the principal has to incentivize the agent is the disclosure of information. The principal aims at maximizing the (discounted) number of times the agent chooses the principal's preferred action. We show that there exists an...

Agents' valuations are interdependent if they depend on the signals of all agents. Previous literature has claimed that with interdependent valuations and multidimen-sional, but independent, signals, efficient auction design is impossible. This paper shows that, on the contrary, it is always...

This paper considers mechanism design problems in environments with ambiguity-sensitive individuals. The novel idea of the paper is to introduce ambiguity in mechanisms so as to exploit the ambiguity sensitivity of individuals. We prove a revelation principle for the partial implementation of...

This paper studies a mechanism design model where the players and the designer are nodes in a communication network. We characterize the communication networks (directed graphs) for which, in any environment (utilities and beliefs), every incentive compatible social choice function is partially...
