We model a boundedly rational agent who suffers from limited attention. The agent considers each feasible alternative with a given (unobservable) probability, the attention parameter, and then chooses the alternative that maximises a preference relation within the set of considered alternatives....

We consider a decision maker who enjoys choosing from a varied set of alternatives. Building on behavioral evidence, we propose testable axioms which characterize preference for variety, and provide a representation theorem. We go on to illustrate the potential effects of preference for variety...

While developing countries have made some progress in achieving human development since the turn of the century, many are still lagging behind in important human development goals such as education, health, nutrition and access to clean drinking water and improved sanitation. Moreover, gender...

Attitudes towards uncertainty have been indicated to be highly context-dependent, and to be sensitive to the measurement technique employed. We present data collected in controlled experiments with 2939 subjects in 30 countries measuring uncertainty attitudes through incentivized measures as...

We study the impact of loss-aversion and the threat of catastrophic damages, which we jointly call threshold concerns, on international environmental agreements. We aim to understand whether a threshold for dangerous climate change is as an effective coordination device for countries to overcome...

This paper studies the effects of social comparison on risk taking be- havior. In our framework, decision makers evaluate the consequences of their choices as changes with respect to both their own and their peers’ conditions. We test experimentally whether different positions in the social...

We conduct a modified dictator game in order to analyze the role self-image concerns play in other-regarding behavior. While we generally follow Konow (2000), a cognitive dissonance-based model of other-regarding behavior in dictator games, we relax one of its assumptions as we allow for...

Innerhalb der ersten Förderphase ist von den Forschungsdatenzentren der Statistischen Ämter des Bundes und der Länder eine Dateninfrastruktur geschaffen worden, die umfangreiche wissenschaftliche Analysen amtlicher Mikrodaten aus allen Bereichen zulässt. In diesem Aufsatz wird insbesondere...

In a less widely known contribution, Béla Martos (1966, Hungarian Academy of Sciences) introduced a generalized notion of concavity that is closely related to what is nowadays known as r-concavity in the operations research literature, and that is identical to what is nowadays known as...
