We experimentally explore individual and interactive decision making ina sequential search task and test whether generally accepted principles ofbounded rationality (aspiration formation, satisficing, and aspiration adjustment)adequately explain the observed search behavior. Subjects can, at...

In the Yes/No game, like in the ultimatum game, proposer and respondercan share a monetary reward. In both games the proposer suggests a rewarddistribution which the responder can accept or reject (yielding 0-payoffs). Thegames only differ in that the responder does (not) learn the suggested...

Even though decision-making in small teams is pervasive in business and in private life, littleis known about subjects’ preferences with respect to individual and team decision-making andabout the consequences of respecting these preferences. We report the results from anexperimental...

We examine the influence of team size on decision making in a beauty-contest experiment.Teams with four members outperform teams with two members and single personssignificantly, whereas the latter two types of decision makers do not differ.

Economics has devoted little attention so far as to whether the type of decision maker matters for economic decisions. However, many important decisions like those on monetary policy or a company’s business strategy are made by (small) groups rather than an individual. We compare behaviour of...

Many decisions in economics and finance have to be made under severe time pressure. Furthermore, payoffs frequently depend on the speed of decision-making, like, for instance, when buying and selling stocks. In this paper, we examine the influence of time pressure and time-dependent incentive...

We study the influence of gender on economic decision making in a two-person bargaining game. By testing hypotheses derived from evolutionary psychology and social role theory, we find that (1) gender per se has no significant effect on behavior, whereas (2) gender pairing systematically affects...

In this note we establish that rational demand expectations willtypically not evolve in an evolutionary model. In an evolutionarymodel beliefs act like a commitment device to more aggressive be-havior. This commitment effect has the same direction for strategicsubstitutes and complements and...

A cyclical network of indirect reciprocity is derived organizing 3- or6-person groups into rings of social interaction where the first individualcan help the second, the second the third, and so on till the last, who inreturn can help the first. Mutual cooperation is triggered by assuming...
