摘要
对于决策问题中的两个行动（a 和 b），每个行动都会产生与具体情况相关的货币奖励，我们研究如何稳健地使行动 a 更有吸引力。如果 a 比 b 更受青睐的信念集合是 a' 比 b 更受青睐的信念集合的子集，而不管风险规避者的效用函数（以金钱为单位）如何，那么行动 a' 就会以这种方式改进 a。我们对这一关系进行了全面描述，并讨论了它在双边贸易和保险中的应用。
For two actions in a decision problem, a and b, each of which that produces a
state-dependent monetary reward, we study how to robustly make action a more
attractive. Action a' improves upon a in this manner if the set of beliefs at
which a is preferred to b is a subset of the set of beliefs at which a' is
preferred to b, irrespective of the risk-averse agent's utility function (in
money). We provide a full characterization of this relation and discuss
applications in bilateral trade and insurance.
