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...

An agent is said to be partially honest if he or she weakly prefers an outcome at a strategy profile with his truthful strategy than an outcome at a strategy profile with his false strategy, then this player must prefer strictly the \true" strategy profille to the \false" strategy profile. In...

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 introduce the concept of payoff distortion in the standard prisoner's dilemma game when strategies are driven by psychological behaviors. This concept enables to take account each player's assessment of the other player's behavior and the asymmetry of information. We determine...

In this paper, we introduce the concept of payoff distortion in the standard prisoner’s dilemma game when strategies are driven by psychological behaviors. This concept enables to take account each player’s assessment of the other player’s behavior and the asymmetry of information. We...

In this paper we examine the relation between strategy-proofness and unanimity in a domain of private good economies with single-peaked preferences. We prove that, under a mild condition, a social choice function satisfies strategy-proofness if and only if it is unanimous. As implication, we...

The goal of this paper is to propose a comparison of four multi-winner voting rules, k-Plurality, k-Negative Plurality, k-Borda, and Bloc, which can be considered as generalisations of well-known single-winner scoring rules. The first comparison is based on the Condorcet committee efficiency...
