How should an agent (the sender) observing multi-dimensional data (the state vector) persuade another agent to take the desired action? We show that it is always optimal for the sender to perform a (non-linear) dimension reduction by projecting the state vector onto a lower-dimensional object...

We study the general problem of Bayesian persuasion (optimal information design) with continuous actions and continuous state space in arbitrary dimensions. First, we show that with a finite signal space, the optimal information design is always given by a partition. Second, we take the limit of...

We investigate how the level of strategic uncertainty affects the coordination power of publicly observed extrinsic signals in a controlled laboratory environment in the context of a bank-run game. We run three treatments featuring different levels of strategic uncertainty. Although theory...

Consider a competitive bank whose illiquid asset portfolio is funded by short-term debt that has to be refinanced before the asset matures. We show that in this setting maximal transparency is not socially optimal, and that the existence of social externalities of bank failures further lowers...

A core responsibility of a central bank is to ensure financial stability by acting as the "lender of last resort" through its Discount Window. The Discount Window, however, has not been effective because its usage is stigmatized. In this paper, we study experimentally how such stigma can be...
