Each member of a group receives a signal about the unknown state of the world and decides upon a utility-maximizing recommendation on the basis of that signal. The individuals have identical preferences. The group makes a decision that maximizes the common utility function assuming perfect...

Financial decisions are among the most important life-shaping decisions that people make. We review facts about financial decisions and what cognitive and neural processes influence them. Because of cognitive constraints and a low average level of financial literacy, many household decisions...

Jeden Tag treffen Manager hunderte von Entscheidungen: die meisten davon in der Annahme, diese seien rational fundiert. Doch ein Großteil unserer Wahrnehmung ist implizit. So verwundert es nicht, dass auch der größte Teil unserer Entscheidungen in Wahrheit unbewusst abläuft. Implizite...

One of the most complex systems is the human brain whose formalized functioning is characterized by decision theory. We present a quot;Quantum Decision Theoryquot; of decision making, based on the mathematical theory of separable Hilbert spaces. This mathematical structure captures the effect of...

In a simple conceptual framework, we organize a multitude of phenomena related to the (mis)prediction of utility. Consequences in terms of distorted choices and lower wellbeing emerge if people have to trade-off between alternatives that are characterized by attributes satisfying extrinsic...

Game and decision theory start from rather strong premises. Preferences, represented by utilities, beliefs represented by probabilities, common knowledge and symmetric rationality as background assumptions are treated as “given.” A richer language enabling us to capture the process leading...

In a simple conceptual framework, we organize a multitude of phenomena related to the (mis)prediction of utility. Consequences in terms of distorted choices and lower wellbeing emerge if people have to trade-off between alternatives that are characterized by attributes satisfying extrinsic...
