%J Journal of economic behavior & organization %R doi: 10.1016/j.jebo.2017.10.022 %X 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. %D 2018 %L eprints3870 %A Ennio Bilancini %A Leonardo Boncinelli %K Costly cognition; Costly signal acquisition; Pooling; Equilibrium refinements; Forward induction; Trembles %I Elsevier %V 145 %T Signaling with costly acquisition of signals %P 141-150
