摘要:
The class of mean-independent incremental risks defined with respect tfr an initial risk, or status quo, is shown tu coincide with the vector space of incremental risks generated from risks that are individually independent of the status quo. Using this characterization of mean independence, aversion toward independent risk increases, together with diversification preference for mean-independent risk increases, implies aversion toward mean-independent risk increases. By contrast, a nondiversifier who is averse ro independent risk increases may nonetheless strictly prefer certain mean-preserving increases in risk.
