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...

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