摘要

我们证明，当且仅当对每个加权效用函数而言，前者比后者更受青睐时，概率分布的似然比才会支配另一种分布。同样，当且仅当每个乐观（或悲观）的决策者都倾向于前者时，概率分布危险率（或反向危险率）才会支配另一种分布。(JEL D11, D83)

Weighted Utility and Optimism/Pessimism: A Decision-Theoretic Foundation of Various Stochastic Dominance Orders

We show that a probability distribution likelihood ratio dominates another distribution if and only if, for every weighted utility function, the former is preferred over the latter. Likewise, a probability distribution hazard rate (or reverse hazard rate) dominates another distribution if and only if, the former is preferred by every optimistic (or pessimistic) decision maker. (JEL D11, D83)
