Experimental studies have shown that trust and reciprocity are effective in increasing efficiency when complete contracting is infeasible. One example is the study by Berg et al. (1995) of the investment game. In this game the person who receives the investment is the one who may reward the...

Principal-agent theory usually assumes that the players are perfectly rational. In contrast, real human decision makers are only boundedly rational. If a firm (principal) wants to design a work contract that maximizes profit, it should consider how workers (agents) will actually react rather...

Whether Individuals can build up and sustain mutually beneficial cooperation or, more generally, whether they comply with social norms, may depend crucially on the observability of their actions. If these cannot be monitored perfectly, the individual might be tempted to egoistically exploit this...

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...

Nach Einordung der Spieltheorie als Rationalverhalten bei interaktiven sozialen Entscheidungsproblemen in Volks- und Betriebswirtschaftslehre werden kurz die (Spiel-)Formen zur Abbildung sozialer Entscheidungssituationen und die wesentlichen Lösungskonzepte vorgestellt. Konkret verdeutlicht...

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...
