This paper models the optimal allocation of research resources aimed at understanding the consequences of a marine invasion. The model assumes returns to research are uncertain. Furthermore there are joint returns to research ahead of the invasion frontier and within the already invaded area. Research ahead of the frontier helps define external damages by establishing the baseline ecosystem services and values; research in the invaded area determines restoration needs and costs associated with controlling the invaded area's population. Additionally, research in the invaded area may improve management of any commercial aspect of the invading species, which may warrant accommodation. In such a case, simple application of the precautionary approach to the invasion has direct quantifiable costs in foregone commercial benefits. Benefits of research thus may accrue either from improved information regarding the potential or actual damages of the invasion, or from improved information for solving the common property management challenges of a commercial species. In the latter case, improved management heightens expectations of foregone benefits ahead of the frontier. We use the Red King Crab (Paralithodes camtschaticus) invasion in Norway as a case study. The crab is a valuable global commodity whose invasive presence in the Barents Sea is impacting the benthos. Harvesting or controlling the crab reduces these impacts, but the net benefits of doing so are uncertain and require both baseline research and restoration research to ascertain. We distinguish the research for Red King Crab in different types based on the potential to reveal marginal external benefits from commercial harvesting. We illustrate how misallocation of research resources can be reduced when the uncertainties create incentives that promote research into tangible commercial benefits over less certain ecosystem benefits. Our analysis suggests that there is currently greater marginal benefit from directing more research resources toward baseline research at the frontier of the invasion instead of making additional investments in research that focuses on the commercial potential of the invasive yet valuable crab.

为商业上有价值的入侵分配研究资源:挪威的红帝王蟹渔业

本文对旨在理解海洋入侵后果的研究资源的最佳分配进行建模。该模型假设研究的回报是不确定的。此外,在入侵前沿之前和已经入侵的区域内,有联合的研究回报。前沿研究通过建立基线生态系统服务和价值来帮助定义外部损害;入侵地区的研究确定了恢复需求和与控制入侵地区人口相关的成本。另外,在被入侵地区的研究可以改善对被入侵物种的任何商业方面的管理,这可能需要妥善安置。在这种情况下,简单地将预防性方法应用于入侵会直接产生可量化的直接商业利益成本。因此,研究的好处可能来自有关入侵的潜在或实际损害的改进信息,或来自解决商业物种共同财产管理挑战的改进信息。在后一种情况下,改进的管理可以提高人们对前沿收益的期望。我们使用红色帝王蟹(桔梗)作为案例研究在挪威的入侵。螃蟹是一种宝贵的全球商品,其在巴伦支海的入侵活动正在影响底栖生物。收获或控制螃蟹可以减少这些影响,但是这样做的净收益尚不确定,需要确定基线研究和恢复研究。我们基于揭示商业性收获的边际外部利益的潜力,对不同类型的红帝蟹的研究进行了区分。我们举例说明了当不确定性产生激励因素时,可以减少研究资源的分配不当现象,这些激励措施可以促进研究取得有形的商业利益,而不是某些生态系统的利益。
