Harry Markowitz passed on June 22, 2023; some four years short of reaching 100 years old. Dr. Markowitz was not a traditional economist. That fact was well- established and documented from his thesis defense at the University of Chicago. When Milton Friedman uttered lines to the effect that Harry’s thesis has nothing wrong with it, but is not an economics dissertation, Dr. Friedman applied a very narrow definition of economics. Harry is acknowledged as a (the) creator of Portfolio Theory. His dissertation was its genesis.

哈里·马科维茨：欣赏

哈里·马科维茨 (Harry Markowitz) 于 2023 年 6 月 22 日去世；距离100岁还有大约四年的时间。马科维茨博士不是传统的经济学家。这一事实在他在芝加哥大学的论文答辩中得到了充分证实和记录。当米尔顿·弗里德曼大意说哈利的论文没有任何问题，但不是经济学论文时，弗里德曼博士应用了非常狭隘的经济学定义。哈利被公认为投资组合理论的创造者。他的论文就是它的起源。
