I am interested in Economic Theory, especially in information economics (the analysis of the strategic decisions of agents to acquire, share, and use information) and in how information asymmetries affect incentives.

Working Papers
This subsumes the first part of "Disclosure and Incentives in Teams". We are working on a second paper encompassing the incentive implications.
This paper introduces a model of group communication, in which a group of senders with conflicting interests collectively communicate with a receiver through the disclosure or non-disclosure of information about a relevant state. Collective disclosure decisions are reached via the aggregation of group members’ disclosure recommendations via a predetermined deliberation procedure. In contrast with classic results from single-agent disclosure, (sequential) equilibria of the group disclosure game typically do not involve full disclosure. We investigate the relation between the group’s deliberation procedure and features of equilibrium communication. In particular, we characterize changes in the deliberation procedure that increase a group’s informativeness; and show that the receiver interprets group messages less favorably for group members who have relatively more power.
The first part of this project is subsumed by the paper"Disclosure by Groups". We are working on a second paper encompassing the incentive implications, and while that is not ready, I am keeping the old project below.
We consider a team-production environment where all participants are motivated by career concerns, and where a team's joint productive outcome may have different reputational implications for different team members. In this context, we characterize equilibrium disclosure of team-outcomes when team-disclosure choices aggregate individual decisions through some deliberation protocol. In contrast with individual disclosure problems, we show that equilibria often involve partial disclosure. Furthermore, we study the effort-incentive properties of equilibrium disclosure strategies implied by different deliberation protocols; and show that the partial disclosure of team outcomes may improve individuals' incentives to contribute to the team. Finally, we study the design of deliberation protocols and characterize productive environments where effort incentives are maximized by unilateral decision protocols or more consensual deliberation procedures.
We study a continuous-time model of partnership, with persistence and imperfect state monitoring. Partners exert private efforts to shape the stock of fundamentals, which drives the pro ts of the partnership, and the profits are the only signal they observe. The near-optimal strongly symmetric equilibria are non-Markovian and are characterized by a novel differential equation that describes the supremum of equilibrium incentives for any level of relational capital. Imperfect monitoring of the fundamentals helps sustain incentives, due to deferred incentives, and increases the partnership's value (Sand in the wheels). Good profit outcomes rally the partners to further increase effort when relational capital is low, but lead them to coast and decrease effort when relational capital is high. Even partnerships with high fundamentals may unravel after a short spell of terrible signals (Beatles' break-up).
