Characterizing core stability with fuzzy games
Shellshear, Evan - 2009
This paper investigates core stability of cooperative, TU games via a fuzzy extension of the totally balanced cover of a TU game. The stability of the core of the fuzzy extension of a game, the concave extension, is shown to reflect the core stability of the original game and vice versa....

Deriving belief operators from preferences
Asheim, Geir B. - 2000
A belief operator derived from preferences is presented. It generalizes ‘belief with probability1’ to incomplete preferences and satisfies minimal requirements for belief operators under weak conditions.

The semantics of preference-based belief operators
Asheim, Geir B.; Søvik, Ylva - 2003
We show how different kinds of belief operators derived from preferences can be defined in terms an accessibility relation of epistemic priority, and characterized by means of a vector of nested accessibility relations. The semantic structure is used to reconcile and compare certain non-standard...

Group Decision Making Under Risk: An Experiment with Student Couples
He, Haoran; Martinsson, Peter; Sutter, Matthias - 2011
In an experiment, we study risk-taking of cohabitating student couples, finding that couples' decisions are closer to risk-neutrality than single partners' decisions. This finding is similar to earlier experiments with randomly assigned groups, corroborating external validity of earlier results.

On the acceptability of the ambient tax mechanism: an experimental investigation
Boun My, Kene; Cochard, François; Ziegelmeyer, Anthony - 2007
Our objective in this paper is to assess the acceptability of the ambient tax. Concretely, we ask subjects to choose between (A) an ambient tax and (B) an individual tax system. In case (A), they actually participate in a game in which their payo depends on all participants' decisions and on...

Deciding to decide: gender, leadership and risk-taking in groups
Ertac, Seda; Gurdal, Mehmet Yigit - 2010
decision to take this responsibility in a group is endogenous in many contexts. In this paper, we experimentally study: (1) the … lower fraction of women being willing to make the group decision than men. The amount of risk taken for the group is … like to make the group decision and the women that do not are no different in terms of how much risk they take for …

Heuristic and exact solutions to the inverse power index problem for small voting bodies
Kurz, Sascha; Napel, Stefan - 2012
Power indices are mappings that quantify the influence of the members of a voting body on collective decisions a priori. Their nonlinearity and discontinuity makes it difficult to compute inverse images, i.e., to determine a voting system which induces a power distribution as close as possible...
