How Mathematical Economics Became (Simply) Economics: The Mathematical Training of Economists during the 1940s, 1950s, and 1960s in the United States by Camila Orozco Espinel CHOPE Working Paper No. 2020-11 November 2020 How mathematical economics become (simply) economics. The mathematical training of economists during the 1940s, 1950s and 1960s in the United States. Camila Orozco Espinel*
[email protected] Abstract Before the use of mathematics in economics was generalized, mathematical and non- mathematically trained economist lived together. This paper studies this period of cohabitation. By focusing on the communication challenges between these two groups during the 1940s, 1950s and 1960s, a watershed moment, this paper analyzes the entrance of mathematics into economists’ training. The paper explores the development of teaching material specific for the mathematical training of social scientists, the entrance of mathematics to economics curriculum and the role of the Social Science Research Council in this delivered process. All these elements are integral to understand how the mathematical methods and tools introduced by a small group of economists during the mid-Twentieth Century come to be adopted by the entire discipline within a couple of decades and thus effected a permanent transformation of economics.
