Signaling with costly acquisition of signals

Abstract

In this paper we investigate the consequences of introducing a cost to observe the signal in an otherwise standard signaling game. Beyond identifying equilibria, which we contrast with those of a standard signaling game, we study their robustness to two important classes of refinements: acting through restrictions on out-of-equilibrium beliefs and through trembles. Our results suggest that more prominence should be given to the pooling outcome on the minimum signal.
