We reexamine Maskin's Theorem by proposing slight modifications on Maskin's conditions of monotonicity and no veto power. We show that any social choice correspondence (SCC) that satisfies strict monotonicity, strict no veto power and unanimity can be implemented in Nash equilibria.

In exchange economies with single-peaked preferences, we find that: (1) several solutions satisfy Theorem 1 of Doghmi and Ziad [Doghmi, A., Ziad, A., 2008-this issue. Reexamination of Maskin's theorem on Nash implementability. Economics Letters.], (2) strict monotonicity is equivalent to Maskin...

In this paper, we reexamine Eliaz's results (2002) of fault tolerant implementation on one hand and we extend theorems 1 and 2 of Doghmi and Ziad (2008a) to bounded rationality environments, on the other. We identify weak versions of the k-no veto power condition, in conjunction with unanimity...

Abstract: In this paper we explore the problem of Nash implementation providing new sufficient conditions called I-monotonicity and I-weak no-veto power. Firstly, we show that these conditions together with unanimity are sufficient for the implementation of social choice correspondences (SCCs)...

In this paper we explore the problem of Nash implementation providing two new properties called I-monotonicity and I-weak no-veto power. These properties form together with unanimity a new sufficient condition for a social choice correspondence to be implementable in Nash equilibria with at...

In this paper, we study the Nash implementation in an allocation problem with single-dipped preferences. We show that, with at least three agents, Maskin monotonicity is necessary and sufficient for implementation. We examine the implementability of various social choice correspondences (SCCs)...
