摘要

对自然资源的过度开发是一个主要问题,全世界都在向可持续收获过渡。为了确定最佳收获策略,包括向可持续收获过渡的最佳速度和方法,政策制定者需要估计自然资源的净现值。先前的研究表明,贴现降低了自然资源的未来价值,但其价格的长期增长可能会部分补偿贴现。然而,自然资源的价格和未来价值也可能受到从过度采收到可持续采收的过渡的影响。在这里,我们提出了一个模型,该模型内化了不可持续收获对可再生自然资源价格的影响。我们表明,向可持续收获的过渡预计将显著提高资源的价格,其速度大于其长期增长。考虑到这一影响,提供可再生自然资源的生态系统的估计净现值就会增加。

Global non-sustainable harvest of renewable resources reduces their present price but increases their net present value

Over-exploitation of natural resources is a major problem, and transitions to sustainable harvest are taking place worldwide. To determine the optimal harvesting strategy, including the optimal speed and approach to transition toward sustainable harvest, policymakers need to estimate the net present values of natural resources. Previous studies have shown that discounting reduces the future value of natural resources, but the long-term increase in their price may partially compensate for discounting. However, the price and future values of natural resources may also be affected by the transition from over-harvesting to sustainable harvest. Here we present a model that endogenizes the effect of non-sustainable harvest on the price of a renewable natural resource. We show that the transition to sustainable harvest is expected to increase the resource’s price significantly, at a rate that is greater than its long-term increase. Incorporating this effect increases the estimated net present value of ecosystems providing renewable natural resources.
