摘要

萨缪尔森(P. Samuelson)在1952年清楚地表明，使用抽象符号的数学经济学分析也可以用清晰的英语(或任何其他语言)写出来。萨缪尔森对正确翻译成英语的数学分析的互换性的评估，显然是由凯恩斯在《通论》第21章第298-299页的第四部分中提出的IS-LM模型所完成的。1936年以来，除了凯恩斯最优秀的学生D. Champernowne之外，宏观经济学家在理解《通论》第21章第298-299页第四部分中提出的凯恩斯的is - lm模型方面的全面失败，唯一可能的两个结论是:(a)他们要么是非常糟糕的应用数学家，要么是(b)他们被伪凯恩斯主义者所误导，特伦斯·哈奇森认为这些伪凯恩斯主义者包括琼·罗宾逊、奥斯汀·罗宾逊、理查德·卡恩、和Roy Harrod在1977年霍巴特的一项研究中

Using P. Samuelson’s 1952 Assessment of the Role of Mathematics in Economics To Evaluate Keynes’s Is-Lm Model in Part IV on Pp. 298–299 in Chapter 21 of the General Theory

P. Samuelson showed clearly in 1952 that a mathematical economics analysis using abstract symbols can be written out in clear English(or any other language) as well.

Samuelson’s assessment of the interchangeability of a correctly translated mathematical analysis into English was clearly accomplished by Keynes in the presentation of his IS-LM model in Part IV on pp.298-299 in Chapter 21 of the General Theory.

The only two possible conclusions that explain the total failure of macroeconomists since 1936, excluding D. Champernowne, Keynes’s best student, to understand Keynes’s IS-LM model as presented in Part IV on pp.298-299 in Chapter 21 of the General Theory is (a) that they are either very poor applied mathematicians or (b) they have been misled by the Pseudo Keynesians, identified by Terrence Hutchison as consisting of Joan Robinson, Austin Robinson, Richard Kahn, and Roy Harrod in a 1977 Hobart study.
