Extensive research on human cooperation in social dilemmas has shown that individuals condition their behaviour upon the behaviour of others. However, few attempts have been made to disentangle the motivations backing conditional cooperation. We try to assess the relative importance of three...

We experimentally investigate how proposers in the Ultimatum Game behave when their cognitive resources are constrained by time pressure and cognitive load. In a dual-system perspective, when proposers are cognitively constrained and thus their deliberative capacity is reduced, their offers are...

Previous research provides compelling evidence that defaults affect individual behaviour in several domains. However, evidence of their influence in strategic interaction is scant. We experimentally investigate the effect of defaults on contributions to a public good and attempt to shed light on...

Previous studies have shown that decision makers are less other-regarding when their own payoff is risky than when it is sure. Empirical observations also indicate that people care more about identifiable than unidentifiable others. In this paper, we report on an experiment designed to explore...

Contrary to the models of deterministic life cycle saving, we take it for granted that uncertainty of one's future is the essential problem of saving decisions. However, unlike the stochastic life cycle models, we capture this crucial uncertainty by a non-Bayesian scenario-based satisï¬cing...

This paper derives and justifies a procedurally fair bidding mechanism and reviews experiments that apply the mechanism to public projects pro- vision. In the experiments, not all parties benefit from provision, and the projects' costs can be negative. The experimental results indicate that the...

Bidding rules that guarantee procedural fairness may induce more equilibrium bidding and moderate other-regarding concerns. Here, we investigate procedural fairness as in Güth (2011). In our experiment, we assume commonly known true values and only two bidders to implement a best-case scenario...

We experimentally examine how group identity affects trust behavior in an investment game. In one treatment, group identity is induced purely by minimal groups. In other treatments, group members are additionally related by outcome interdependence established in a prior public goods game. Moving...

In one-shot investment games where each player's payoff is a convex combination of own and other's profit, we measure trust by the amount given to the trustee and trustworthiness by the amount returned to the trustor by the trustee. Does the degree of payoff interdependence increase both trust...

We define and experimentally test a public provision mechanism that meets three basic ethical requirements and allows community members to influence, via monetary bids, which of several projects is implemented. For each project, participants are assigned personal values, which can be positive or...
