In this letter to the editors of the Journal of the History of Economic Thought, I present my results on Ragnar Frisch’s rocking horse model, published in an earlier issue of the same journal, and detail why the comments by Jean-Marc Ginoux and Franck Jovanovic on my paper have no grounding. I explain the role of initial conditions on the amplitude of cycles and trend in Frisch’s solution, and emphasize that my contribution was to show that Frisch built a model where cycles and growth came from the same economic mechanism.

致编辑的信：皇帝没有衣服：对吉努和约万诺维奇的答复

在这封写给《经济思想史杂志》编辑的信中，我介绍了我对拉格纳·弗里施的摇马模型的研究结果，该模型发表在同一杂志的早期期刊上，并详细说明了让-马克·吉努克斯和弗兰克·约万诺维奇发表评论的原因我的论文没有任何基础。我解释了弗里希解决方案中初始条件对周期和趋势幅度的作用，并强调我的贡献是表明弗里希建立了一个模型，其中周期和增长来自同一经济机制。
