Abstract:  We study a multidimensional Sender-Receiver game in which Receiver can acquire limited information after observing the Sender's signal. Depending on the parameters describing the conflict of interest between Sender and Receiver, we characterise optimal information disclosure and the information acquired by Receiver as a response. We show that in case of partial conflict of interests (aligned on some dimensions and misaligned on others) there is negative value of information in the sense that Receiver would be better off if she could commit not to extract private information or to have access to information of less quality. We present applications to optimal bonus policies in academia and to the optimal funding allocation between the projects.​

Abstract:  We propose the first class of simultaneous voting mechanisms in which each Nash equilibrium is coalition-proof. These mechanisms hence prevent the coordination failures which arise when some (coalition of) voters could have induced an outcome that they all prefer to the equilibrium outcome had they agreed on a common strategy. In each of these mechanisms, some voter(s) has the right to veto a list of alternatives. For each specification of the veto rights, each of these mechanisms implements a Veto by random priority rule introduced by Moulin [1981]. We then discuss necessary conditions for arbitrary mechanisms to implement a Pareto efficient rule ensuring that each equilibrium is coalition-proof. We show that the presence of veto rights in the mechanism is unavoidable to achieve this demanding implementation notion.

Abstract:  We design a mechanism, Majority voting with random checks, that fully implements the majority rule for binary social decisions. After a simultaneous vote over the two options, the winner must be confirmed by at least one agent from a random sample of agents voting sequentially. The mechanism incentivizes agents to act truthfully as a lottery is held if no agent confirms the outcome. Our mechanism also reduces by almost half the number of stages required for implementation. Furthermore, we extend our results to incomplete information and abstention and introduce additional implementation mechanisms based on the concept of network formation.
