Conflicts and Choices in Biodiversity Preservation
用简单模型探讨如何将多样性纳入目标函数并制定成本效益排序标准，通过分析美国濒危物种保护数据检验理论与实践的契合度，指出目标函数模糊是当前核心问题。
The purpose of this article is to examine the preservation of biodiversity as an economic problem. Using a very simple prototype model, the authors discuss how to include diversity in the objective function and how to develop a simple cost-benefit ranking criterion for ordering priorities. Then they analyze data on endangered species preservation decisions in the United States to shed light on the conformity of theory with practice. A basic theme is that the core issue in biodiversity preservation today is the fuzziness of the objective function.
