It is well-known that the ability of the Vickrey-Clarke-Groves (VCG) mechanism to implement efficient outcomes for private value choice problems does not extend to interdependent value problems. When an agent's type affects other agents' utilities, it may not be incentive compatible for him to...

I analyze private value auction design and assume only that bidders are risk averse and have positive wealth effects (i.e. the good is normal). I show removing the standard quasilinearity restriction leads to qualitatively different solutions to the auction design problem with respect to both...

Different evaluators typically disagree how to rank different candidates since they care more or less for the various qualities of the candidates. It is assumed that all evaluators submit vector bids assigning a monetary bid for each possible rank order. The rules must specify for all possible...

We claim that the emergence of trust is best explained by relation-based arguments. After brie fly surveying alternative explanations which concentrate on material payoffs both with self-centered and with other-regarding preferences, we examine theoretical discussions of cooperative and trust...

We study the process of equilibrium selection in games when players have social preferences of the type discussed, among others, by Rabin (1993) and Segal and Sobel (2007). To this end, we employ a standard noisy version of the best response dynamics. We obtain several results concerning some...

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

We claim that the emergence of trust is best explained by relation-based arguments. After briefly surveying alternative explanations which concentrate on material payoffs both with self-centered and with other-regarding preferences, we examine theoretical discussions of cooperative and trust...

There is robust experimental evidence that in the ultimatum game real players often prefer a fair allocation which seems to be in contrast to rational decision making. In this paper rational maximizing behavior as well as norm-guided fair behavior are two possible behavioral rules. It is argued...
