The present research experimentally examines the influence of group identity 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 additionally related by outcome...

Die menschliche Art ist eine Spezies, die durch Einsatz von Institutionen undNormensystemen kollektive Güter (oder Übel) bereitzustellen vermag.1 Kollektive Güterbilden typischerweise Antworten auf Kollektivgut-Probleme. Eine besonders wichtige Klassesolcher Kollektivgut-Probleme entsteht im...

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...

Relying on the specific example of ultimatum bargaining experiments this paperexplores the possible role of empirical knowledge of behavioural “norm(ative)facts” within the search for (W)RE – (Wide) Reflective Equilibria on normativeissues. Assuming that “pro-social” behaviour...

Human decision making is a process guided by different and partly competing mo-tivations that can each dominate behavior and lead to different effects depending on strength and circumstances. “Over-stylizing” neglects such competing concerns and context-dependence, although it facilitates...

One may hope to capture the behavioral and emotional eects of downsizingthe labor force in rather abstract settings as an ultimatum game (see Fischeret al. (2008)), or try to explore downsizing in its more natural principalagentscenario with a labor market background. We pursue the latter...

In the experimental scenario several agents repeatedly invest in n (n _ 2)state-specic assets. The evolutionarily stable and equilibrium (Blume andEasley, 1992) portfolio for this situation requires to distribute funds accordingto the constant probabilities of the various states. The dierent...

We experimentally test how acceptance thresholds react to the decisionof the proposer in a three party ultimatum game to exclude oneof two responders with veto power from the game. We elicit responderacceptance thresholds in case the proposer decides to exclude one ofthem, what increases the...

Theoretically and experimentally, we generalize the analysis of acquiringa company (Samuelson and Bazerman 1985) by allowing for competition ofboth, buyers and sellers. Naivety of both is related to the idea that higherprices exclude worse qualities. While competition of naive buyers...

Economic theory has evolved without paying proper attention to behavioral approaches,especially to social, economic, and cognitive psychology. This has recently changed byincluding behavioral economics courses in many doctoral study programs. Although thisnew development is most welcome, the...
