The xistence of definitional economics--Stigler's and Leibenstein's war of the words
分析了斯蒂格勒与莱本斯坦关于X效率理论的争论，指出定义分歧导致经济分析陷入无效争论，并探讨了这种策略对经济讨论的影响。
The inability to agree on definitions ultimately can condemn economic analysis and debate to fruitless argumentation. The sharp interchange between Stigler and Leibenstein did little to clarify the issues surrounding the controversial theory of X-efficiency. Given their conflicting agendas, discussion between these two opponents consisted largely of talking at cross purposes. This paper examines the motivations of the two protagonists as well as considering the impact such tactics have on economic debate and discussion. Copyright 2002, Oxford University Press.
