Group selection and social preferences
Weibull, Jörgen (contributor);  … - 2005 - [Elektronische Ressource], Rev. September 27, 2005
A large number of individuals are randomly matched into groups, where each group plays a finite symmetric game. Individuals breed true. The expected number of surviving offspring depends on own material payoff, but may also, due to cooperative breeding and/or reproductive competition, depend on...

Collectively ranking candidates : an axiomatic approach
Güth, Werner - 2011
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...

Collusion-Proof and Fair Auctions
Hagen, Martin - 2019
In the standard auction model, we provide a necessary and sufficient condition on the value domain under which non-trivial mechanisms exist that satisfy group strategy-proofness and symmetry. In particular, this condition is satisfied (violated) if values are drawn from a finite set (an interval)

Lotteries vs. all-pay auctions in fair and biased contests
Epstein, Gil S.; Mealem, Yosef; Nitsan, Shemuel - 2012
The form of contests for a single fixed prize can be determined by a designer who maximizes the contestants' efforts. This paper establishes that, under common knowledge of the two asymmetric contestants' prize valuations, a fair Tullock-type endogenously determined lottery is always superior to...

Voting on a sharing norm in a dictator game
Vanberg, Christoph - 2007
I conduct an experiment to assess whether majority voting on a nonbinding sharing norm affects subsequent behavior in a dictator game. In a baseline treatment, subjects play a one shot dictator game. In a voting treatment, subjects are first placed behind a 'veil of ignorance' and vote on the...

Gender Differences in Moral Judgment and the Evaluation of Gender-Specified Moral Agents
Capraro, Valerio - 2017
Whether, and if so, how exactly gender differences are manifested in moral judgment has recently been at the center of much research on moral decision making. Previous research suggests that women are more deontological than men in personal, but not impersonal, moral dilemmas. However, typical...
