Much of the evidence supporting the EllsbergÕs paradox comes from experiments on individual choice and judgement.In this study, we address the issue whether, in market experiments, there is a tendency for anomalous behaviour to disappear or to be reduced as a consequence of market experience...

This paper presents four incentivised experiments analysing jointly the separate role of immediate integral emotions and knowledge in individual decision making under ambiguity. Reactions to a natural source of uncertainty (i.e., forthcoming real-world election results) were measured using both...

Several well-established surveys ask questions in order to measure subjective well-being. In some questionnaires, questions relate to happiness, in others, to individual well-being or satisfaction or to both happiness and satisfaction.

In this work we use data from two sets of midterm exams and question-by-question evaluations of confidence levels and construct different indicators in order to study predictive ability and overconfidence. Our results show that (1) there is a significant evidence of a good ability of...

In this paper we examine the performance of theories of decision making under uncertainty/ambiguity from the perspective of their descriptive and predictive power, taking into account the relative parsimony of the various theories. To this end, we employ an innovative experimental design which...

The purpose of this paper is to deepen the knowledge of consumer behaviour in information goods markets, taking as a reference the sound recording market. In particular, its aim is twofold: on the one hand it attempts to get new insights on consumers paying special attention to their willingness...
