The quadratic scoring rule (QSR) is often used to guarantee an incentive compatibleelicitation of subjective probabilities over events. Experimentalists haveregularly not been able to ensure that subjects fully comprehend the consequencesof their actions on payoffs given the rules of the games....

Idiosyncratic risk attitudes are usually assumed to be commonly knownand restricted to own payos. However, the alternatives faced by a decisionmaker often involve risks for others' payos as well. Motivated by theimportance of other-regarding preferences in social interactions, this paperexplores...

We show that for many classes of symmetric two-player games, the simple decision rule \imitate-the-best" can hardly be beaten by any other decision rule. Weprovide necessary and sufficient conditions for imitation to be unbeatable and showthat it can only be beaten by much in games that are of...

The paper compares two models of evolution in symmetric twoplayergames with incomplete information. One model postulates thatthe type of a player is fixed, and evolution works within types. Inthe other model type-contingent strategies evolve. In the case of twotypes and two strategies it is...

Situations where independent agents need to align their activities to achieve individually and socially beneficial outcomes are abundant, reaching from everyday situations like fixing a time for a meeting to global problems like climate change agreements. Often such situations can be described...

Hierarchy plays an integral role in organizational structure and practices, as well as in society more generally. In Confucian-influenced cultures, and especially in South Korea, social hierarchies are often based on age, and age dynamics can therefore influence social decision-making and...

We study network formation with n players and link cost α 0. After the network is built, an adversary randomly deletes one link according to a certain probability distribution. Cost for player ν incorporates the expected number of players to which ν will become disconnected. We focus on...
