Economics of the Endangered Species Act
探讨经济学家如何帮助评估保护濒危物种的社会收益是否超过私人成本，以提高保护措施成功的概率，对政策制定者和土地所有者有参考价值。
The Endangered Species Act of 1973 is one of our most far-reaching and controversial environmental laws. While the benefits of protecting endangered species accrue to the entire nation, a significant fraction of the costs are borne by the private landowners who shelter about 90 percent of the nearly 1,000 listed species. The pressure to know whether the social benefits of preservation exceed the private costs has thrust economics into ongoing reauthorization debate. This paper examines how economists can help better the odds that when society imposes and bears costs to protect endangered species, it will be more likely to succeed.
