The phenomenon of predating predators requires at least three specimens to whom we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well fed but must also avoid being hunted by player 3. One major...

This paper raises the question of whether differential regularity in the repetition of a set of items would elicit a differential regularity in the repetition of a set of items would elicit a differential liking for those items. Two experiments are reported. In the first, 120 participants either...

In plausible theories of bounded rationality actors are not stimulus-response machines but human beings. As such they are guided by theories that predict the course of the world and prescribe how they should try to intervene in that course. Since boundedly rational human beings cannot only...

Many consumption prices are highly volatile. It would certainly overburden our cognitive system to fully adjust to all these changes. Households therefore often rely on simple heuristics when deciding what to consume, e.g. in the form of a constant budget share for a specific consumption...

This paper brings together views on choice making as have been developed in philosophy, psychology, and economics. Starting from specific examples the relative merits of different approaches are discussed. The conclusion that models of boundedly rational behavior are the future of social science...

In phase 1 of our experiment every participant plays the ultimatum game with each of the other five group members, each taking the role of proposer and responder. For each of the offers one learns how many participants would have accepted it. The pie is 30 times larger in phase 2. It thus pays...

The general framework of decision emergence (Güth, 200a) is applied to the specific decision task of a proposer in ultimatum bargaining, i.e. to choosing how much the responder should be offered. For this purpose the "Master Module" as well as its submodules "New Problem Solver", "Adaption...
