This paper provides a new way to identify conditional cooperationin a real-time version of the standard voluntary contribution mechanism. Ourapproach avoids most drawbacks of the traditional procedures because it relieson endogenous cycle lengths, which are defined by the number of contributors...

We use a two-person public goods experiment to distinguish betweene±ciency and fairness as possible motivations for cooperative behavior.Asymmetric marginal per capita returns allow only the high-productivityplayer to increase group payo®s when contributing positive amounts....

The notion of choice inconsistency is widely spread in the literature on behavioraleconomics. Several approaches were used to account for the observation that peoplereverse their choices over time. This paper aims to explain the formation of resolutionsregarded as internal self-binding devices....

Costly signaling of commitment to a group has been proposed as an explanation forparticipation in religion and ritual. But if the signal’s cost is too small, freeriders willsend the signal and behave selfishly later. Effective signaling may then be prohibitivelycostly. If the average level of...

Unlike previous attempts to implement cooperation in a prisoners’ dilemma gamewith an infinite horizon in the laboratory, we focus on extended prisoners’ dilemmagames in which a second (pure strategy) equilibrium allows for voluntary cooperationin all but the last round. Our four main...

Which inequalities among individuals are considered unjust? This paper reportsthe results of an experiment designed to study distributive choices dealing with arbitrarilyunequal initial endowments. In a three-person distribution problem wheresubjects either know or do not know their endowments,...

Recent literature has questioned the existence of a learning foundationfor the partially cursed equilibrium. This paper closes the gap by showingthat a partially cursed equilibrium corresponds to a particular analogy-based expectation equilibrium.

In line with the widely applied principle of just deserts, we assume that the severityof the penalty on a contract offender increases in the harm on the other. Whenthis principle holds, the influence of the efficiency of the agreement on the incentivesto abide by it crucially depends on whether...

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...

In a two-person finitely repeated public goods experiment, we use intentionsdata to interpret individual behavior. Based on a random-utilitymodel specification, we develop a relationship between a player's beliefsabout others' behavior and his contributions' plans, and use this relationshipto...
