Valuing the Multiple Impacts of Pesticide Use in the UK: A Contingent Ranking Approach
采用条件排序法，以绿色消费品为支付载体，估计农药使用对人类健康和生物多样性影响的价值。结果显示，消费者平均只愿容忍6至8例人类疾病来拯救整个农田鸟类物种。
The contingent ranking method was used to estimate the value of the human health and biodiversity impacts associated with pesticide applications, using a “green” consumer product as a payment vehicle. Specification testing showed that the standard conditional logit model provides a representation of these data preferable to the rank‐ordered logit variant. The resulting estimates ‐ which perform well in terms of standard validity tests ‐ show that, on average, consumers are only willing to tolerate between six and eight cases of human illness to save an entire species of farmland birds.
