中文摘要 | 假設某人要將固定資源分配於 n 群團體,且其對不同的分配型態有某種偏好。若 此人的最理想分配為 y, 且其偏好為齊序、強可分,則我們証明:y 與任意分配 x 之間的 確實指標( exact index )即為熵族指標之一員。 給定前述偏好型態與熵族指標間一一對 應之關係,我們可以檢視:是否某些熵族指標背後存有不合理之偏好基礎?我們發現:確實 有些熵族指標對應著遞減、非凸的偏好型態。這些對應著不合理偏好型態的熵族指標,應予 以排除。 |
英文摘要 | Suppose the domain of preference ordering is the set of all possible allocations of a fixed amount of resources among n groups, and suppose y refers to a decision maker's most preferred point. If the decision maker's preferences are homothetic and strongly separable, we show that the exact index between y and a particular allocation x is a member of the well-known cross entropy class. Given that the entropy class has a one-to-one correspondence with the preference ordering of a decision maker, we are able to examine whether some of the entropy measures adopted in the literature have unreasonable underlying assumptions with regard to preferences. We find that some members of the entropy class correspond to the unreasonable assumption that the decision maker's marginal utility is negative and the corresponding preferences are nonconvex. These unreasonable measures should be ruled out, and only a subset of the generalized entropy indexes have a plausible micro foundation of individual preferences. |
