We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices.Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

In this paper we study information revelation on asset markets with endogenousand exogenous information. Our results indicate that superior informationcan only be exploited in the beginning of trading. Information disseminateson the market and informational advantages are counter-balancedover...

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...

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 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...
