内容摘要
Utility function and stochastic dominance are two fundamental devices in ranking risk prospects. The former evaluates prospects with a cardinal function, while the latter examines if one prospect could be preferred by all decision makers sharing certain qualitative properties. Each approach has its pros and cons: utility function delivers a complete order, but is sensitive to the functional specification; stochastic dominance is more robust, but is often found too partial to apply. Towards a balance, we employ a utility function as a benchmark, and meanwhile allow preferences to deviate from the benchmark to a prespecified extent. The resulting set of preferences is broader than a single specification but narrower than what underlies traditional stochastic dominance. The consensus of these preferences in ranking prospects, termed as benchmark stochastic dominance, combines the relative advantages of utility function and traditional stochastic dominance. We provide distribution conditions of the new criterion, demonstrate its relationships with existing variants of stochastic dominance, and illustrate its implementation with an empirical investigation of the attractiveness of bonds versus stocks.
