In Old Chicago: Simons,Friedman, and the Development of Monetary‐Policy Rules

This paper examines the different policy rules proposed by Henry Simons, who, beginning in the mid‐1930s, advocated a price‐level stabilization rule, and by Milton Friedman, who, beginning in the late‐1950s, advocated a rule that targeted a constant growth rate of the money supply. Although both rules shared the objective of eliminating the policy uncertainty emanating from discretion, they differed because of the different views of Simons and Friedman about the stability of secular relationships. Simons’ rule relates to modern rules that emphasize the pursuit of price stability as representing optimal monetary policy.
