The Exclusion Theorem in the Weberian Space
在韦伯空间下统一考察输入价格、输出价格、运输费率和技术不确定性对排除定理有效性的影响，利用二阶条件和比较静态分析推导新条件，部分结果推广了前人研究。
In this paper we employ a unifying approach to examine the exclusion theorem in a Weberian space under various types of uncertainty: input price or output price uncertainty, transport rate uncertainty, and technology uncertainty. The novelty of our approach is the usage of second‐order conditions and comparative static analysis in the derivation of conditions for thevalidity of the exclusion theorem. Our main results are new and some are generalizations of those obtained in prior studies.
