In this paper, we reexamine Eliaz's results (2002) of fault tolerantimplementation 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 thek-no veto power condition, in conjunction with unanimity and...

In this work, we extend the concept of Fault Tolerant Implementation of Eliaz (2002) to the concept of Fault Tolerant Implementation in incomplete information environments. In particular, we work in a domain where information is non-exclusive by choosing a model of pure exchange economy. As 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)...

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...

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...

This paper belongs to the recent literature which explores the consequence(s) of allowing some player(s) to be minimally honest in the standard Nash implementation. In this literature, Dutta and Sen(2012) give sufficient conditions for the implementation of social choice correspondences in Nash...

In this paper we establish the link between strategy-proofness and unanimity in a domain of private good economies with single-peaked preferences. We introduce a new condition and we prove that if this new property together with the requirement of citizen sovereignty are held, a social choice...
