Expected utility theory (EUT) is currently the standard framework which formally defines rational decision-making under risky conditions. EUT uses a theoretical device called von Neumann-Morgenstern utility function, where concepts of function and random variable are employed in their...

In this paper we provide choice-process experimental evidence that the attraction effect is a short-term phenomenon, that disappears when individuals are given time and incentives to revise their choices. The attraction (or decoy) effect is the most prominent example of context effects, and it...

In this study we introduce a new stochastic choice rule that categorizes objects in order to simplify the choice procedure. At any given trial, the decision maker deliberately randomizes over mental categories and chooses the best item according to her utility function within the realized...
