摘要：We perturb the bilateral bargaining model by introducing small ambiguity (via the epsilon contamination model) about the agents' types. We assume that the preferences are characterized by ambiguity aversion (Gilboa-Schmeidler). The rest of the setup is exactly as in Myerson and Satterthwaite [10]. And we show that in this environment, it is possible to design a mechanism that
generates almost-efficient trade. Crucially, the mechanism has to be extensive-form; standard (normal form) direct revelation mechanism can only generate outcome that is continuous with respect to the amount of ambiguity.
