Transport generates many externalities, some related to atmospheric pollution. In this paper, we focus on two: greenhouse gases, and local pollution. In the search for optimal transport policies, these two externalities have usually been analysed separately. Here, we study them jointly, in a...

Testing whether risk professionals (here insurers) behave differently under risk and ambiguity when they cover catastrophic risks (floods and earthquakes) and non-catastrophic risks (fires), this paper reports the results of the first field experiment in the United States designed to distinguish...

The aim of this paper is to illustrate the contribution that taking a psychological perspective can bring to the study of decision-making in economics. The article pursues the idea that it can be useful to combine a psychological analysis of judgment and decision-making with an economic analysis...

In this paper, we build on the emerging literature on group decision-making to study the so-called ‘group shift’ effect, i.e., groups are less risk-averse than individuals. Our study complements past research in two ways. First, we study the group shift effect under two sources of...

This article presents the results of an experiment designed to test theoretical predictions about the impact of public compensation schemes and ambiguity on insurance and self-insurance decisions. Consistent with theory, we find that government assistance significantly reduces willingness to pay...

L’objectif de ce travail est double. Premièrement, à l’aide de modélisations théoriques, nous proposons plusieurs prédictions liées au comportement d’assurance face à différents programmes d’intervention publique et à l’ambiguïté. Deuxièmement, nous testons ces prédictions...
