We study ultimatum and dictator experiments where the first moverchooses the amount of money to be distributed between the playerswithin a given interval, knowing that her own share is fixed. Thus, thefirst mover is faced with scarcity, but not with the typical trade-off betweenher own and the...

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...

This paper revisits and extends the experiment on the solidarity gameby Selten and Ockenfels (1998). We replicate the basic design of the solidaritygame and extend it in order to test the robustness of the fixed totalsacrifice' effect and the applied strategy method. Our results only...

A unique indivisible commodity with an unknown common value is owned bygroup of individuals and should be allocated to one of them while compensating theothers monetarily. We study the so-called fair division game (Güth, Ivanova-Stenzel,Königstein, and Strobel (2002, 2005)) theoretically and...

Norms play an important role in establishing social order. Thecurrent literature focuses on the emergence, maintenance and impactof norms with regard to coordination and cooperation. However, theissue of norm-related conict deserves more attention. We develop ageneral theory of \normative...

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...

During the last three decades the ascent of behavioral economics clearly helped tobring down artificial disciplinary boundaries between psychology and economics.Noting that behavioral economics seems still under the spell of the rational choicetradition – and, indirectly, of behaviorism – we...

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,...

This paper examines the occurrence and fragility of information cascades in laboratory experiments.One group of low informed subjects make predictions in sequence. In a matchedpairs design, another set of high informed subjects observe the decisions of the first group andmake predictions....
