We consider the partitioning of a society into coalitions in purely hedonic settings; i.e., where each player's payo is completely determined by the identity of other members of her coalition. We rst discuss how hedonic and non-hedonic settings di er and some su cient conditions for the existence of core stable coalition partitions in hedonic settings. We then focus on a weaker stability condit...

I suggest that there is a basic incompatibility between this qualitative notion of preference and the decision-theoretic notion of utility. I demonstrate that while reasoning and decision making in the former can f...

Even though the interaction of intrinsic motivation and concerns for social approval has important implications both for crowding out of intrinsic motivation through incentives and for producer choices, little is known about this interaction empirically. We present a laboratory experiment that provides evidence of a relevant interaction effect in the context of ethical consumption. We elicit a ...
