Les relations fonctionnelles entre les couts et la decision de poursuivre un investissement dans un projet de recherche et de developpement sont examinees avec 407 etudiants en commerce. Les sujets lisent un scenario dans lequel 10%, 30%, 50%, 70% ou 90% d'un budget de 10 millions de dollars ont ete investis. Un groupe doit indiquer s'il est souhaitable d'investir les fonds restants pour finir le projet.
