Cause and Cure of the Crisis (ctnd)

February 2013 already gave a weblog entry Cause and Cure of the Crisis and November 2013 a YouTube video – though with a rather slow speed of presentation.

Now in September 2014 there is a short paper (MPRA  58592) with the same title. The paper gives a review of the books DRGTPE and CSBH that are at the core of this weblog – apart for our admiration for Art Buchwald and attention to the education of mathematics.

This may be occasion to pay a small tribute to John Maynard Keynes (1883-1946) and Jan Tinbergen (1903-1994). The analysis on the cause and cure of the crisis is based upon their work, and thus the world can only cure the crisis by properly reading up on Keynes and Tinbergen as well. It requires an understanding not only on economic theory but also econometric methods, with a role for mathematics.

There is another storyline that links up to mathematics education.

Tinbergen studied physics and wrote his thesis with Paul Ehrenfest (1880–1933). As a student he walked in Leiden, saw the poverty, decided to study economics, and doing so he created econometrics.

Ehrenfest’s wife Tatyana Afanasyeva (Kiev, 1876 – Leiden, 1964) wrote on math education too. Her work was hotly debated in small circles. One of the discussants was Hans Freudenthal (1905-1990), another German immigrant to Holland. Freudenthal became the promotor of Pierre van Hiele (1909-2010), which makes the circle round, see this entry on this weblog.
