We show that neither Peleg's nor Tadenuma's well-known axiomatizations of the core by non-emptiness, individual rationality, super-additivity, and max consistency or complement consistency, respectively, hold when only convex rather than balanced TU games are considered, even if anonymity is...

This study experimentally analyses traders' choices, with and without asymmetric information, based on the riding-bubble model. While asymmetric information has been necessary to explain a bubble in past theoretical models, our experiments show that traders have an incentive to hold a bubble...

In this paper we consider a model of an economy with a common pool resource. Under decreasing returns to scale, it is well-known that no Nash equilibrium attains Pareto efficiency. We examine whether it is possible to achieve Pareto efficiency and avoid the tragedy of the commons through...

We isolate strategic and non-strategic motivations of sanctioning in a repeated public goods game. In two experimental treatments, subjects play the public goods game with the possibility to sanction others. In the STANDARD sanctions treatment, each subject learns about the sanctions received in...

Some new axiomatic characterizations and recursive formulas of the Shapley value are presented. In the results, dual games and the self-duality of the value implicitly play an important role. A set of non-cooperative games which implement the Shapley value on the class of all games is given

One of the main issues in economics is the trade-off between marginalism and egalitarianism. In the context of cooperative games this trade-off can be framed as one of choosing to allocate according to the Shapley value or the equal division solution. In this paper we provide tools that make it...

Cooperative game theory addresses two problems: coalition formation and payoff distribution. We hypothesize that the existence of the core, which is a fundamental concept in cooperative game theory, affects coalition formation, and we examine this hypothesis through a laboratory experiment. In...

A situation in which a finite set of players can obtain certain payoffs by cooperation can be described by a cooperative game with transferable utility, or simply a TU-game. A one-point solution for TU-games assigns a payoff distribution to every TU-game. In this paper, we discuss a class of...
