How people develop beliefs about themselves (self-theories) plays an important role on motivation and achievement as shown by Carol Dweck’s life-long research. In this paper, we conduct a field experiment to investigate whether self-theories impact overconfidence and risk taking. Self-theories...

This article offers some economic insights for the debate on the reversible geological disposal of radioactive waste. Irreversibility due to large sunk costs, an important degree of flexibility and several sources of uncertainty are taken into account in the decision process relative to the...

We consider a firm that has to choose a technology to produce a given good. This technology drives a multiplicative large-scale risk of incident for Society: the total potential level of damage increases with the level of activity. Contrary to what is often argued in the literature, we show that...

In this paper, we analyze the choice of primary prevention made by individuals who bear a risk of being in bad health and an additive risk (of complications) that occurs after a disease has been diagnosed. By considering a two argument utility (depending on wealth and health), we show that the...

In this paper, we focus on the adverse selection issue that prevails in an economy when the regulator is not able to observe the type of the abate- ment costs of the firms. The regulator decides the total level of emission that minimizes the total social cost and he sells them to the firms at...

Recent surveys report the increasing number of muddy flows in many areas, and point out the fact that agricultural practices (among others) influence significantly the risk and severity of muddy flows. In this paper, we investigate the economic incentives that can be given to the farmer to adopt...

In this paper, we investigate an audit policy that allows a regulator to control past declarations of an agent who is caught to fraud in the current period or to adopt an action that is not desirable for Society. Coupled with redistribution effects due to the production of a public good, we show...

Dans cet article nous construisons un système de contrôle des émissions polluantes qui combine permis d’émission et taxes sur la base du modèle de Roberts et Spence (1976). Nous relâchons l’hypothèse de linéarité de la fonction de transferts monétaires entre le régulateur et les...
