N2 - We define decreasing higher-degree Ross risk aversion and provide an intuitive interpretation for it. We show that all deteriorations of background risk in the sense of n -th risk increase raise risk aversion in the Arrow-Pratt sense if and only if decreasing ( n + 1 ) -th degree Ross risk aversion holds. Meanwhile, the utility functional form of the agent with decreasing ( n + 1 ) -th degree Ross risk aversion is specified. Our result also implies decreasing 3-rd degree Ross risk aversion can be used to characterize the sufficient condition of risk vulnerability. Moreover, our analysis shows the implication of decreasing n / m -th ( n > m ≥ 1 ) Ross risk aversion.
