2. In the 1950’s and 1960’s, monetarists, led by Milton Friedman, proposed a different primary cause for the depression: contraction in the money supply caused by numerous simultaneous bank failures. They argued that increasing the money supply was the key to alleviating or reversing the depression. Even today, “[e]conomists and economic historians are almost evenly split as to whether the traditional monetary explanation that monetary forces were the primary cause of the Great Depression is right, or the traditional Keynesian explanation that a fall in autonomous spending, particularly investment, is the primary explanation for the onset of the Great Depression.” (https://en.wikipedia.org/wiki/Great_Depression#cite_note-in_JSTOR-19)

16. Mathematical Economics at Cowles, presented at The Cowles Fiftieth Anniversary Celebration, June 3, 1983, by Gérard Debreu The Wikipedia article says he started in January, 1942. However, the source cited (https://web.archive.org/web/20070615230712/http://cowles.econ.yale.edu/P/reports/1942-46b.htm) actually just says 1942. I suspect this is because this source only applies to the period starting in 1942. (“Biographies and brief surveys of the activities of research associates during 1942–1946”) For these reasons, I place more credence in the July, 1941, date.
