Columbia. Friedman’s lecture notes to first Hotelling lecture in Mathematical Economics, 1933

 

 

On October 3, 2017, Antoine Missemer tweeted an image of an undated examination question by Harold Hotelling “Describe two mathematical contributions to economics published before 1910”. One should note that asking students to talk about work published at least a quarter century before the current academic year is not necessarily a deep dive into the history of economics, though of course Cournot, Bertrand and Edgeworth had achieved “historical” fame by 1933.

From Harold Hotelling’s course in Mathematical Economics taught in the first semester of 1933/34 at Columbia, Milton Friedman kept about forty-five 3 by 5 inch index cards worth of notes (both sides). From his first lecture, we can put together a convenient “short list” of Hotelling’s chosen greatest hits in mathematical economics. I have taken the liberty of expanding Friedman’s abbreviations, figuring the main purpose of transcribing archival material is to ease digital search down the road.

Earlier postings include a list of Hotelling’s courses and his class rolls at Columbia as well as an outline and exam for his course in mathematical economics offered at North Carolina (1946, 1950).

Milton Friedman’s student notes to Harold Hotelling’s first lecture in Mathematical Economics (1933)

9/2/33 (1)

Hotelling, Harold on Mathematical Economics

Has been stated that methodological difference between economics + natural sciences is that in former cannot + in latter do experiments

Not entirely true: in econonomics may experiment, + in some physical sciences (e.g. astronomy, meteorology etc.) do not experiment.

Better dividing line to be found in number of relevant factors
