Defining Risk
从历史视角出发，利用20世纪的思想，论证了风险概念难以被正式定义，并揭示了其本质局限，对金融和风险管理领域有启发意义。
The financial literature frequently mentions risk, but it lacks a widely accepted definition of risk. This omission is no coincidence. Risk is an intuitive notion that resists formal definition. Adopting a largely historical perspective, this article draws on ideas that emerged during the 20th century and uses them to formalize specific limits to our ability to ever define the notion of risk. In doing so, it offers insights into the nature of risk.
