Background : Seasonal influenza concerns the worldwide population every year, whilst pandemic influenza is an unpredictable threat. Due to an important socioeconomic impact, mitigation measures must be specified. Governments elaborate vaccination policy based on scientific evidence. However,...

We study the influence of risk and time preferences on trust and trustworthiness by conducting a field experiment in Vietnamese villages and by estimating the parameters of the Cumulative Prospect Theory and of quasi-hyperbolic time preferences. We find that while probability sensitivity or risk...

We experimentally manipulate two aspects of the cognitive environment — cognitive depletion and recent sugar intake — and estimate their effects on individuals’ time preferences in a way that allows us to identify the structural parameters of a simple (α,β,δ) intertemporal utility...

We study the attitudes of junior and senior employees towards strategic uncertainty and competition, by means of a market entry game inspired by Camerer and Lovallo (1999). Seniors exhibit higher entry rates compared to juniors, especially when earnings depend on relative performance. This...

We investigate how different forms of scrutiny affect dishonesty, using Gneezy’s (2005) deception game. We add a third player whose interests are aligned with those of the sender. We find that lying behavior is not sensitive to revealing the sender’s identity to the observer. The option for...

This article analyses belief updating when agents receive a signal that restricts the number of possible states of the world. We create an experiment on individual choice under uncertainty. In this experiment, the subject observes an urn, containing yellow and blue balls, whose composition is...

Le taux de préférence pour le présent est un facteur important qui conditionne la durée des épisodes de chômage. Les transitions du chômage sont analysées par l’estimation d’un modèle à hasard proportionnel à temps discret avec trois sorties à risques concurrents : contrat à...
