A flexible policy instrument to encourage externality abatement technologies in salmon aquaculture
本文提出将上网电价补贴（一种动态庇古补贴）作为监管工具，借鉴西班牙和德国可再生能源经验，促进挪威鲑鱼养殖业投资海虱减排技术。
Aquaculture has been identified as a food sector with potential to provide protein and essential micronutrients to a growing global population, with salmon aquaculture often viewed as a leader in innovation and adoption of new technologies. Despite a broad range of negative externalities in salmon aquaculture, sea lice infestations remain the most harmful of environmental issues within the industry. In response to these challenges and driven by the need for a higher degree of control over the production conditions, salmon producers in Norway have been investing in new technologies that are often perceived as the last resort for sea lice abatement. The challenge is to design a regulatory regime that encourages innovation toward a sustainable mix of production technologies in the future. In this paper, we propose to use feed-in tariffs (FITs), a dynamic Pigouvian subsidy, as a regulatory instrument that can promote investments in abatement technologies by the salmon farming industry. We ground our discussion of FITs for aquaculture in experiences from the renewable energy sector in Spain and Germany.
