The theory of full implementation has been criticized for using integer/modulo games which admit no equilibrium (Jackson (1992)). To address the critique, we revisit the classical Nash implementation problem due to Maskin (1977, 1999) but allow for the use of lotteries and monetary transfers as...

We assess the strength of the different conditions identified in the literature of robust mechanism design. We focus on three conditions: ex post incentive compatibility, robust monotonicity, and robust measurability. Ex post incentive compatibility has been shown to be necessary for any concept...

We consider the robustness of extensive form mechanisms to deviations from common knowledge about the state of nature, which we refer to as information perturbations. First, we show that even under arbitrarily small information perturbations the Moore-Repullo mechanism does not yield (even...

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 UNE concept is considered as the robustness...

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 said to be implementable in Nash equilibrium if...

Maskin and Tirole [Maskin, E., Tirole, J., 1999. Unforeseen contingencies and incomplete contracts. Review of Economic Studies, 66, 83-114] show that indescribability does not matter for contractual incompleteness when there is symmetric information both at the contracting stage and at the...

We consider the robustness of extensive form mechanisms to deviations from common knowledge about the state of nature, which we refer to as information perturbations. First, we show that even under arbitrarily small information perturbations the Moore-Repullo mechanism does not yield (even...
