Abstract

Le contrôle est l'un des instruments majeur de répression des activités illégales. Cette dimension est intégrée aux analyses économiques du crime sous la forme d'une probabilité de détection et fondée seulement sur l'aversion au risque. La psychologie cognitive montre que la perception des probabilités peut elle-même varier d'un individu à l'autre. Cet article propose une analyse expérimentale de ce type d'erreur de perception, qualifiée de biais d'optimisme, à partir d'une série de choix entre une activité légale et une activité illégale. Les traitements expérimentaux évaluent la mesure dans laquelle les modalités de contrôle peuvent, à probabilité donnée, influencer les biais d'optimisme. Les résultats suggèrent que les politiques de communication de lutte contre les activités frauduleuses doivent favoriser la perception idiosyncrasique du risque.
