The value of a statistical life (VSL) is a key parameter in the analysis of government policy. Most policy decisions are made under ambiguity. This paper studies the effect of changes in ambiguity perception on the VSL. We propose a definition of increases in ambiguity perception based on Ekern’s (1980) definition of increases in risk. Ambiguity aversion alone is not sufficient to lead to an increase in the VSL when the decision maker perceives more ambiguity. Our results highlight the importance of higher order ambiguity attitudes, particularly ambiguity prudence.

歧义变化下的统计生命的价值

统计寿命（VSL）的值是分析政府政策的关键参数。大多数政策决定都是模棱两可的。本文研究了歧义感变化对VSL的影响。我们基于Ekern（1980）对风险增加的定义，提出了歧义感增加的定义。当决策者意识到更多的模糊性时，仅模糊性厌恶是不足以导致VSL增加的。我们的结果强调了更高阶歧义态度的重要性，尤其是歧义谨慎。
