In-group favoritism in social dilemma situations is one of the main findings of studies in Social Identity Theory. We investigate what causes the in-group bias: is it due to mere group affiliation or, alternatively, is guilt-aversion a possible explanation? We induce group membership in a...

In our experiment, a dictator game variant, the reported outcome of a die roll determines the endowment (low/high) in a subsequent dictator game. In one treatment the experimenter is present and no cheating is possible, while in another subjects can enter the result of the roll themselves. Moral...

The satisficing approach is generalized and applied to finite n-person games.Based on direct elicitation of aspirations, we formally define the conceptof satisficing, which does not exclude (prior-free) optimality but includesit as a border case. We also review some experiments on strategic...

On a heterogeneous experimental oligopoly market, sellers choose a price,specify a set-valued prior-free conjecture about the others' behavior, andform their own profit-aspiration for each element of their conjecture. Weformally define the concepts of satisficing and prior-free optimality...

We experimentally investigate how affective processes influence proposers’and responders’ behaviour in the Ultimatum Game. Using a dualsystemapproach, we tax cognitive resources through time pressure andcognitive load to enhance the influence of affective processes on behaviour.We find that...

Contrary to the models of deterministic life cycle saving, we take itfor granted that uncertainty of one's future is the essential problem ofsaving decisions. However, unlike the stochastic life cycle models, we capturethis crucial uncertainty by a non-Bayesian scenario-based...
