We enrich the choice task of responders in ultimatum games by allowing them to independently decide whether to collect what is offered to them and whether to destroy what the proposer demanded. Such a multidimensional response format intends to cast further light on the motives guiding responder...

Based on an axiomatically derived provision rule allowing community members to endogenously determine which, if any, public project should be provided, we perform experiments where (i) not all parties benefit from provision, and (ii) the projects' costs can be negative. In the tradition of legal...

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...

Bidding rules that guarantee procedural fairness may induce more equilibrium bidding and moderate other-regarding concerns. In our experiment, we assume commonly known true values and only two bidders to implement a best-case scenario for other-regarding concerns. The two-by-two factorial design...

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...

We report on an experiment designed to explore the interrelation of otherregardingconcerns with attitudes towards risk and delay when the latterhave a social dimension, i.e., pertain to one's own and another person'spayos. For this sake, we compare evaluations of several prospects, eachof which...

In one-shot investment game experiments where each player's payo is a convexcombination of own and other's prot, trust remains unaected by the extent of interdependencewhereas trustworthiness reacts positively to it.

The present research experimentally examines the ininfluence of groupidentity on trust behavior in an investment game. In one treatment,group identity is manipulated only through the creation of artificial(minimal) groups. In other treatments group members are additionallyrelated by outcome...
