| 单词 | uncertainty |
| 释义 | uncertainty A consciousness of lack of knowledge about present facts or future possibilities. This is the normal condition of the human race, not only in economics. Some writers distinguish between risk and uncertainty: risk covers cases where while individual events are not known, people believe that they know the frequency distribution from which they are drawn at random; uncertainty covers cases where such beliefs are absent. Events of the type covered by risk, such as individual deaths, fires, or motor accidents, are potentially insurable, while events of the types covered by uncertainty are not. Many authors, however, simply use risk and uncertainty interchangably. |
