Abstract

Nous proposons d'étudier dans un modèle à deux secteurs de production, les effets d'une incertitude portant sur la qualité de l'environnement sur les comportements de choix de portefeuille et d'épargne des agents. Nous supposons que les individus investissent dans les firmes par l'intermédiaire de groupes d'investissement. Nous montrons, alors qu'à l'équilibre macroéconomique, un accroissement de risque peut conduire à une diminution du stock de capital et favoriser les firmes à effet certain sur l'environnement. Ces résultats dépendent des effets de la pollution sur la consommation et des comportements de précaution des individus
