In this article we analyze whether markets for organic and conventional salmonids are integrated and to what extent the price premium is reduced when organic supply grows. Increased organic supply reduces prices if organic and conventional markets are independent, while price premiums remain unchanged with perfect interdependency, since conventional supply is large. With imperfect interdependency, price premium flexibility evolves. Cointegration is identified at the farm-level trout and retail-level salmon markets, while the Law of One Price (LOP) only holds in the trout market when tested without trend. Relative inverse demand indicates price premiums could decline by approximately one-quarter when the organic market share doubles. The results show organic and conventional salmonid prices are tied together and that price premiums might be reduced when organic supply increases. Price premiums might prevail when investing in organic salmonid farming, but not at the current level in the long run.

有机供应增长会导致价格溢价降低吗?丹麦的鲑鱼案例

在本文中,我们分析了有机和传统鲑鱼市场是否整合,以及当有机供应增加时价格溢价降低的程度。如果有机市场和传统市场是独立的,那么增加的有机供应会降低价格,而价格溢价保持不变,完全相互依赖,因为传统供应量很大。由于不完全的相互依赖,价格溢价的灵活性不断发展。协整在养殖场级别的鳟鱼和零售级别的三文鱼市场被确定,而一价定律 (LOP) 仅在没有趋势的情况下测试时才适用于鳟鱼市场。相对逆向需求表明,当有机市场份额翻倍时,价格溢价可能会下降约四分之一。结果显示有机和传统鲑鱼的价格是联系在一起的,当有机供应增加时,价格溢价可能会降低。在投资有机鲑鱼养殖时,价格溢价可能占优势,但从长远来看不会达到目前的水平。
