Abstract

Un cadre d'analyse dans lequel les consommateurs sont imparfaitement informés sur le contenu des produits est utilisé pour étudier les effets d'un système d'information publique. Bien qu'un label avec les mentions "contient des organismes génétiquement modifiés" (OGM) ou un label "ne contient pas d'OGM" informent les consommateurs, ces labels n'ont pas nécessairement d'effets similaires sur le surplus des consommateurs. Il est montré que le label "contient des OGM" devrait être utilisé quand le ratio des consommateurs opposés à la consommation d'OGM par rapport aux consommateurs indifférents aux OGM est élevé, alors que le label "ne contient pas d'OGM" devrait être utilisé si ce ratio est bas.
