Hawtrey, Harvard, and the Origins of the Chicago Tradition
论证弗里德曼所宣称的芝加哥货币传统，除规则而非相机抉择这一点外，其余要素均可在霍特里、杨和柯里等人的早期著作中找到，且存在从霍特里经哈佛到芝加哥的直接影响链。
Milton Friedman has claimed that his monetary economics derives from a Chicago tradition that, in the 1930s, offered a monetary explanation of cyclical fluctuations in general and the Great Depression in particular, an optimistic view of the power of monetary policy, and a case for governing it by rules rather than discretion. It is argued that all the elements of this tradition except the last are to be found in earlier writings of Ralph Hawtrey, Allyn Young, and Lauchlin Currie and that there is much evidence to point to a direct influence running from Hawtrey, through Harvard, to Chicago.
