We develop an inclusive wealth type index for natural capital in the Barents Sea that accounts for ecosystem services via trophic interactions. We consider three key fish species in the Barents Sea under stochastic growth dynamics. Compared to evaluation at market prices, the estimated wealth from the inclusive wealth approach is several times higher. Ecosystem wealth depends on the management scheme, and we consider both business as usual (BAU) and an optimized ecosystem-based management scheme (EBM). While BAU maintains wealth near its current level (5% increase in the long run), EBM increases wealth with almost 20% in the short run and more than 25% in the long run. Realized shadow prices suggest that prey species stocks are undervalued when evaluated at market prices.

巴伦支海的生态系统财富

我们为巴伦支海的自然资本开发了一个包容性财富类型指数，该指数通过营养相互作用考虑了生态系统服务。我们在随机生长动态下考虑了巴伦支海的三种主要鱼类。与以市场价格评估相比，普惠财富法估算的财富要高出数倍。生态系统财富取决于管理方案，我们同时考虑一切照旧 (BAU) 和优化的基于生态系统的管理方案 (EBM)。虽然 BAU 的财富保持在当前水平附近（长期增长 5%），但 EBM 增加了近 20% 的短期财富和 25% 以上的长期财富。已实现的影子价格表明，当以市场价格进行评估时，猎物种群的价值被低估了。
