利用选择实验数据估算统计物种的价值
Using Choice Experiment Data to Estimate the Value of a Statistical Species
摘要
Wildlife interactions influence the value of outdoor recreation, but little prior work links welfare to wildlife abundance. We use a choice experiment to estimate willingness to pay for recreation as a function of the probability of seeing a species. Our estimates are analogous to the value of statistical life, so we term them the Òvalue of a statistical speciesÓ (VSS). We provide empirical VSS estimates of common North American species that may be transferable to benefit-cost analyses of comparable recreational settings supporting similar wildlife. We then show how they help assess wildlife management benefits and costs using a case study.

野生动物互动会影响户外游憩的价值，但此前鲜有研究将福利与野生动物丰度联系起来。我们采用选择实验来估计游憩支付意愿，并将其表示为看到某一物种的概率的函数。我们的估计结果类似于统计生命价值，因此我们将其称为“统计物种价值”（VSS）。我们提供了北美常见物种的VSS经验估计值，这些估计值或可迁移用于支持类似野生动物的可比游憩环境的成本收益分析。随后，我们通过一个案例研究展示这些估计值如何有助于评估野生动物管理的收益与成本。
