大多数可以被称为风险厌恶的比较静态的结果是在只有一个不确定性来源的情况下获得的。最主要的例子（它最初推动了风险厌恶的定义）是，更多的风险厌恶者愿意为防范风险支付更高的保费。众所周知，当存在另一个不确定性来源时，结果通常不会延续下去。本文发展的条件下，比较静力结果是稳健的，对引入额外的不确定性来源。
Most results in what can be termed the comparative statics of risk aversion are obtained when there is only one source of uncertainty. The primary example (which originally motivated the definition of risk aversion) is that more risk averse people are willing to pay a higher premium for insuring against risk. It is known that the results do not generally carry over when there is another source of uncertainty. The paper develops conditions under which comparative statics results are robust against the introduction of additional sources of uncertainty.
