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...

Although one may hope to achieve equality of stated profits withoutenforcing it, one may not trust in such voluntary equality seeking andrather try to impose rules (of bidding) guaranteeing it.[...]

Most research in economics models agents somehow motivated by out-comes. Here, we model agents motivated by procedures instead, whereprocedures are dened independently of an outcome. To that end, wedesign procedures which yield the same expected outcomes or carry thesame information on other's...

Different evaluators typically disagree how to rank different candidates since theycare more or less for the various qualities of the candidates. It is assumed that allevaluators submit vector bids assigning a monetary bid for each possible rank order.The rules must specify for all possible...

Why is it that well-intentioned actions can create persistent conflicts? While norms are widely regarded as a source for cooperation,this article proposes a novel theory in which the emergence of normscan be understood as a bargaining process in which normative conflicts explain the nally...

Unanimous voting as the fundamental procedural source of political legitimacy grants vetopower to each individual. We present an axiomatic characterization of a class of biddingprocesses to spell out the underlying egalitarian values for collective projects of a“productive state”. At heart...

The existing literature acknowledges that a mismatch between the experimenter'sand the subjects' models of an experimental task can adversely aect the interpretation ofdata from laboratory experiments. We discuss why the two common experimental designs(between-subjects and within-subjects) used...

The measurement of social norms plays a pivotal role in many social sciences.While economists predominantly conduct experiments, sociologistsrather employ (factorial) surveys. Both methods, however, suer from distinctweaknesses. Experiments, on the one hand, often fall short in themeasurement of...

The literature on social preferences provides overwhelming evidence of departuresfrom pure self-interest of individuals. Experiments show that people care about others’well-being and their relative standing. This paper investigates whether this type ofbehavior persists when risk comes into...

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...
