Fairness is a strong concern as shown by dictator and ultimatum experiments. Efficiency, measured by the sum of individual payoffs, is a potentially competing concern in games such as the prisoners' dilemma. In our experiment participants can increase efficiency by gift giving. In the one-sided...

In the framework of expected utility theory, risk attitudes are entirely capturedby the curvature of the utility function. In cumulative prospect theory (CPT) riskattitudes have an additional dimension: the weighting of probabilities. With thismodication, one question arises naturally: since...

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...

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...

Charness et al. (2007b) have shown that group membership has a strong effect on individualdecisions in strategic games when group membership is salient through payoff commonality.In this comment I show that their findings also apply to non-strategic decisions, even when nooutgroup exists, and I...

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)...

In this paper we experimentally test skewness seeking at the individuallevel. Several prospects that can be ordered with respect to the third-degreestochastic dominance (3SD) criterion are ranked by the participants of theexperiment. We find that the skewness of a distribution has a...
