We study the relationship between two-agent implementation problems and the notionof interim efficiency due to Holmström and Myerson (1983) in Bayesian environmentswith private values and independent types. We present a general property, Bayesianefficiency, and show that it is sufficient for...

We study Nash implementation by natural price-quantity mechanisms in pure exchange economies when agents have intrinsic preferences for responsibility. An agent has an intrinsic preference for responsibility if she cares about truth-telling that is in line with the goal of the mechanism designer...

This paper investigates the robustness of Dutta and Sen's (2012) Theorem 1 to weaker notions of truth-telling. An individual honesty standard is modeled as a subgroup of the society, including the individual herself, for which she feels truth-telling concerns. An individual i is honest when she...
