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)...

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

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...
