Voluntary Disclosure and Perceptions of Fairness: A Research Note

Abstract

We conduct an experiment on voluntary disclosure within a simple bargaining setting wherein a proposer must choose one of two possible offers and a responder chooses whether to reject or accept that offer. In one treatment the proposer has the option to disclose whether a fairer (more equal) offer was available relative to the one chosen. Under standard economic theory, a responder will interpret no disclosure to mean the proposer’s offer was the less fair alternative, and so a proposer who is making the fairer offer will disclose. In consequence, voluntary disclosure should perform as well as mandatory disclosure in motivating proposers to make fair offers. Given their rejection rates, we find responders properly infer the meaning of non-disclosure. However, despite the correct inferences made by responders, proposers submit twice as many fair offers with mandatory disclosure than with voluntary disclosure. Our results suggest that the choice of voluntary versus mandatory disclosure has consequences for resource allocation within the firm even though under standard assumptions about preferences it should not.
