Promotion of Eco-Products and Environmental Regulation with Learning-by-Doing Promotion of Eco-Products and Environmental Regulation with Learning-by-Doing 小谷, 浩示 29 コタニ, コウジ 柿中, 真 28 カキナカ, マコト Kotani, Koji 31 Kakinaka, Makoto 30 ecoproduct environmental regulation product differentiation learning-by-doing optimal control ecoproduct environmental regulation product differentiation learning-by-doing optimal control This paper studies a dynamic model of eco-product planning, where an eco-product supplied by a single producer is differentiated from a conventional product generating negative externalities, and the production technology of the eco-product is characterized by learning-by-doing. The result states that the learning effect causes the eco-product to be more promoted and brings about more favorable outcomes on social welfare. This study also examines how the environmental regulation on the conventional product, associated with a price distortion, affects the promotion of the eco-product, consumer surplus, the single producer's profit, and negative externalities. It is shown that the impact of the environmental regulation is similar to that of a rise in the learning effect. Furthermore, whether or not the environmental regulation should be adopted is highly dependent on the degree of the learning effect. In the presence of a large learning potential, the environmental regulation may not only promote the eco-product effectively but also improve social welfare through intensifying the learning effect. departmental bulletin paper 2006-03-01 application/pdf Economics & Management Series https://iuj.repo.nii.ac.jp/record/380/files/EMS_2006_07.pdf https://iuj.repo.nii.ac.jp/records/380 eng
