Abstract

This paper introduces the possibility of signaling into a finite-depositor version of the Diamond-Dybvig model. More precisely, the decision to keep the funds in the bank is assumed to be unobservable, but depositors are allowed to make it observable by signaling, at a cost. Depositors consecutively decide whether to withdraw their funds or continue holding balances in the bank, and they choose if they want to signal the latter decision. If the cost of signaling is moderate, then bank runs do not occur. Moreover, in the unique outcome no signals are made, so the unconstrained-efficient allocation is implemented without any costs.

Keywords:
Bank run
Sequential game
Signaling
Iterated deletion of strictly dominated strategies

Resumen

El presente trabajo introduce la posibilidad de la señalización en una versión del modelo de Diamond y Dybvig con una número limitado de depositantes. Más concretamente, se presupone que la decisión de mantener los fondos en el banco no es observable, pero los depositantes pueden hacerlo mediante la señalización, que estaría sujeta a una coste. Los depositantes deciden de forma consecutiva si desean retirar sus fondos o seguir manteniendo saldos en el banco, así como si desean señalizar esta última decisión. Si el coste de señalización es reducido, no tiene lugar el pánico bancario. Por otra parte, no se emite ninguna señal en el único equilibrio, por ello se aplica la asignación eficiente sin restricciones sin que suponga ningún coste.
