Wenn der Nutzen von Gesundheitsleitungen bewertet wird, geht man davon aus, den Zusammenhang zwischen Ursache und Wirkung mit wissenschaftlichen Methoden belegen zu können. Generell wird die randomisierte kontrollierte Studie (RCT) als Goldstandard zur Gewinnung wissenschaftlicher Evidenz über Kausalzusammenhänge angesehen. Da zunehmend Daten erhoben(More)
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 treatment this is only possible for one of the two partners.(More)

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 research is strongly endorsed. But we also admit that it is(More)
