I consider the implementation problem under complete information and employ Nash equilibrium as a solution concept. A socially desirable rule is given as a correspondence from the set of states to the set of outcomes. This social choice rule is…

I consider a strategic game form with a finite set of payoff states and employ undominated Nash equilibrium (UNE) as a solution concept under complete information. I propose notions of the proximity of information according to which the continuity of…
