We study Nash implementation by natural price-quantity mechanisms in pure exchange economies with free-disposal (Saijo et al., 1996, 1999) where agents have weak/strong intrinsic preferences for honesty (Dutta and Sen, 2012). Firstly, the Walrasian rule is shown to be non-implementable where all...

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...

The paper proposes necessary and sufficient conditions for the natural implementation of (efficient) social choice correspondences (SCCs) in pure finite exchange economies when some of the agents are partially honest. A partially honest agent is an agent who strictly prefers to tell the truth...

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...

We generalize the canonical problem of Nash implementation by allowing agents to voluntarily provide discriminatory signals, i.e. evidence. Evidence can either take the form of hard information or, more generally, have differential but non-prohibitive costs in different states. In such...

Noting that a full characterization of Nash-implementation is given using a canonical-mechanism and Maskin's theorem (Maskin, 1999) is shown using a mechanism with Saijo's type of strategy space reduction (Saijo, 1988), this paper fully characterizes the class of Nash-implementable social choice...

Two experts make yes/no predictions about whether an event, such as an economic crisis, will occur. They receive private signals about the likelihood of the event that are much more informative than the coarse recommendations they can ultimately convey. The experts may care about both absolute...

This paper discusses the implications of strategic voting for institutional design in environments where the only role of elections is to aggregate information. We adopt a mechanism design perspective, which assumes that prior to a standard voting game, a fictitious designer has to select the...
