Generalized Expected Utility Analysis of Multivariate Risk Aversion
将Machina的广义期望效用分析扩展到多元分布偏好,定义了更风险厌恶的关系并刻画了递减风险厌恶,证明标准期望效用结果可推广到局部效用函数。
This paper extends M. J. Machina's generalized expected utility analysis to preferences over multivariate distributions. Within the extended framework, the relation more risk averse than is defined, characterized, and applied to the analysis of consumption-saving decisions under risk. The notion of decreasing risk aversion is also characterized. The paper shows that standard results obtained within the framework of expected utility theory can be extended if the restrictions imposed on the utility function in expected utility theory are imposed on the local utility functions in Machina's theory.
