Unlike previous attempts to implement cooperation in a prisoners’ dilemma gamewith an infinite horizon in the laboratory, we focus on extended prisoners’ dilemmagames in which a second (pure strategy) equilibrium allows for voluntary cooperationin all but the last round. Our four main...

We study interaction effects between intra-firm conflicts and interfirm competitionon a duopolistic market with seller firms employing one or more agents and imple-menting tournament incentives. We show that inter-firm competition leads to higherincentive intensity, higher efforts and output...

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...

The satisficing approach is generalized and applied to finite n-person games.Based on direct elicitation of aspirations, we formally define the conceptof satisficing, which does not exclude (prior-free) optimality but includesit as a border case. We also review some experiments on strategic...

On a heterogeneous experimental oligopoly market, sellers choose a price,specify a set-valued prior-free conjecture about the others' behavior, andform their own profit-aspiration for each element of their conjecture. Weformally define the concepts of satisficing and prior-free optimality...

Similar to welfare economics where with(out) interpersonal comparisonsone defines unique (set-valued) welfare (Pareto) optima, we present a frameworkfor one-person decision making where with(out) a prior probability distributionindividual optimality prescribes usually a unique (set of)...

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...

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...
