Multi-commodity price risk hedging in the Atlantic salmon farming industry
研究了大西洋鲑鱼养殖户如何利用多种商品（包括鲑鱼和三种饲料原料）进行价格风险对冲，发现多商品对冲在短期能降低风险，在长期能改善风险收益平衡。
Cost management has received limited attention in the aquaculture industry due to historically high profit margins. This trend, however, is not likely to continue. This creates a need for knowledge on optimally managing financial risks. In this study, we address the joint input-output price hedging problem of salmon farmers. Along with salmon, we consider three essential commodities used in fish feed mixtures. We use state-of-the-art copula models to examine multi-commodity hedging strategies. Our results show significant potential in reducing the joint price risk. Our key finding is that multi-commodity hedging improves hedging effectiveness for short horizons and risk-return trade-off for longer horizons. Salmon farmers face a trade-off where longer hedging horizons yield increased effectiveness and lower costs, yet require increased pre-planning of slaughtering volumes.
