本文提出了一种混合Logit方法来评估高山道路上死亡风险的降低。除了常见的道路事故外，这些道路的使用者还面临着雪崩和崩塌等自然灾害的风险。此外，道路使用者的个人风险随其接触频率的不同而不同。根据来自山区的频繁暴露的受访者和来自瑞士城市的较少暴露的受访者的选择实验数据，我们能够估计统计寿命(VSL)的价值。此外，我们还探讨了受访者在个人支付意愿上的差异，这取决于他们的风险敞口和其他个人特征。在阿尔卑斯山道路发生致命事故的情况下，我们对VSL的估计在600万至780万瑞士法郎(390万至510万欧元)之间。我们发现VSL依赖于社会经济和感知因素，但不会因危险的类型而显着改变。这些发现表明，VSL可能会进行调整，以考虑到不同社会群体的不同风险偏好，但没有证据表明，对自然危害存在“恐惧”溢价。
This paper presents a mixed logit approach to the valuation of reductions in mortality risk on Alpine roads. In addition to common road accidents, users of these roads face risks from natural hazards such as avalanches and rockfalls. Moreover, the individual risk of road users varies with the frequency of their exposure. Drawing on choice experimental data of frequently exposed respondents from a mountainous region and less frequently exposed respondents from a city in Switzerland, we are able to estimate the value of statistical life (VSL). Furthermore, we explore how respondents differ in their individual willingness-to-pay depending on exposure and other individual characteristics. Our estimates of the VSL in the context of fatal accidents on Alpine roads are in the range of CHF 6.0–7.8 million (€3.9–5.1 million). We find the VSL to be dependent on socio-economic and perceptional factors but to be not significantly altered by the type of hazard. These findings imply that the VSL might be adjusted to account for heterogonous risk preferences of different societal groups, but there is no evidence of a ‘dread’ premium for natural hazards.
