On a preference relation between random variables related to an investment problem
摘要
Related to a stochastic investment problem which aims to deter-mine when is it better to first invest a larger amount of money and afterwards asmaller one, in this paper we introduce a new preference relation between randomvariables. We investigate the link between this new relation and some well-knownstochastic order relations and present some characterization properties illustratedwith numerical examples.
