Chicago. Theory and Measurement of Demand. Henry Schultz, 1934

The undated reading list and bibliography for Henry Schultz’s advanced course “Theory and Measurement of Demand” transcribed below, included in Milton Friedman’s papers at the Hoover Institution Archives, are almost certainly from the Autumn quarter, 1934. This was the academic year that Friedman worked as Henry Schultz’s research assistant at the University of Chicago and audited the course.


Friedman audited the Schultz course, Theory and Measurement of Demand

According to the draft of his Civil Service application Milton Friedman worked as personal assistant to Henry Schultz October 1934-August 1935 at a yearly salary of $1600. In his list of courses on a separate page, Friedman writes that he “visited”, i.e. did not take for credit, a course in the Theory of Demand given by Henry Schultz during the academic year 1934-35.

Friedman describes his work for Schultz

From a carbon-copy, presumably an attachment to the same Civil Service application in Box 5, Folder 4, Friedman writes:

“I lived in Chicago, Ill. from September, 1934 to August, 1935 while employed by the University of Chicago.

My educational training and experience gained while working with Professor Schultz this past year are most relevant to the position for which I am applying. I have aided Prof. Schultz on the theoretical questions underlying his forthcoming book on “The Theory and Measurement of Demand”, a subject intimately connected with consumption. In this connection I have had to survey the literature on demand and consumption. In addition to the theoretical work I have been in charge of related statistical studies and was largely responsible for the planning and direction of a statistical study of the demand for meats in the United States, on which study three statistical assistants were employed. In the course of the study I wrote several memoranda analyzing and interpreting the data and results. The results of the analysis are being published by Prof. Schultz in…[next page missing].”

    1. Excellent point. Just checked Chipman and Lenfant (2002) “Slutsky’s 1915 Article: How It Came to be Found and Interpreted” In page 4 of this reprint, they note “First published recognition of Slutsky’s important paper in America may be found in Schultz’s 1935 article: Interrelations of Demand, Price and Income.” Stigler’s notes for the course include a handout, with the heading: “Economics 405/The Theory and Measurement of Demand/Professor Henry Schultz/University of Chicago/December, 1934” and with the title: “Summary of Relations between Demand, Prices and Income”. On the last page of the handout, Schultz writes: “The foregoing development is, with the exception of Section 5, essentially that given by Eugene Slutsky in his “Sulla teori del bilancio del consummatore”, Giornale degli economisti, LI (1915), 1-26.” He points to the essential similarity of the equations to those derived by Hicks and Allen, then writes (underlined for emphasis): “They [the equations] are among the most important equations in the entire field of demand, although they are as yet comparatively unknown to economists.”

      1. My conclusion. The date of the handout is the end of the autumn quarter, 1934 at the University of Chicago, so Schultz was probably working this up during that quarter since the course syllabus and bibliography must have been prepared before the start of the quarter.

        1. Schultz learned about Slutsky’s paper in Europe in 1934. Back in Chicago he commissioned a translation dated December 1934, perhaps only typed. This translation is mentioned in a letter by Friedman to Hotelling in the spring of 1935. Stigler who edited (with Boulding) the 1952 volume with a translation of Slutsky (1915) hired another translator (Olga Ragusa), although one would think he would have had knowledge from Friedman of the 1934 translation.

          1. So I guess the mystery is who in Europe tipped Schultz to Slutsky. Schultz picked up on Konüs’ work via the Bortkiewicz review of Haberler’s Habilitationsschrift on index numbers. Recognizing the importance of Slutsky and Konüs, Schultz certainly did have a good nose for significant work.

          2. No, he didn’t have a good enough nose for significant work. He had worked on demand since the early 1920s without finding out that Slutsky (1915) had been on the shelves in the UChicago Library all the time. He even was in letter exchange with Slutsky in the early 1930s about translating Slutsky (1927), see the editorial footnote to Slutsky’s article in Econometrica 1937, without finding out about Slutsky (1915). Schultz was very depressed in the years before he died. Possibly this was due to poor marital relations but disappointment over not discovering Slutsky may have added to it.

  1. Henry Schultz is in in group picture from the Cowles Commission Research Conference in Colorado Springs in July 1938 along with Abba Lerner, Rene Roy, Alfred Cowles, Abraham Wald and many others.
