We examine how WTP for a reduction in road-mortality risk varies with different individual characteristics and how subjective mortality-risk estimates differ from objective (statistical) mortality-risk values. Using data from a Swedish contingent valuation study, we find some support that WTP declines with age and background risk, but we find no support that WTP varies with health status. Further, we find that respondents underassess their own mortality risks, both road- and total-mortality risks, compared to the objective risk measures for Sweden at the time of the survey.
我们研究了为降低道路死亡风险的支付意愿(WTP)如何随不同个体特征而变化,以及主观死亡风险估计与客观(统计)死亡风险值有何不同。利用瑞典一项条件价值评估研究的数据,我们发现有一定证据支持支付意愿随年龄和背景风险下降,但没有证据支持支付意愿随健康状况而变化。此外,我们发现与调查时瑞典的客观风险衡量标准相比,受访者低估了他们自身的死亡风险,包括道路死亡风险和总死亡风险。
