A partially-honest individual is a person who follows the maxim, "Do not lie if you do not have to" to serve your material interest. By assuming that the mechanism designer knows that there is at least one partially-honest individual in a society of n≥3 individuals, a social choice rule (SCR)...

Consider a society with two sectors (issues or objects) that faces a design problem. Suppose that the sector-2 dimension of the design problem is fixed and represented by a mechanism Γ², and that the designer operates under this constraint for institutional reasons. A sector-1 mechanism Γ¹...

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...
