Keynes’s IS-LM model in the General Theory, defined in (r,Y) space and contained in chapter 21 in Part IV on pp. 298-299 of the General Theory, was derived from the underlying D-Z model of Chapter 20 that incorporated expectations and uncertainty into the P(expected economic profits-Z) and...

J M Keynes stated the following on p.xii of his General Theory on December 13,1935: “I have also had much help from Mrs. Joan Robinson….who have read the whole of the proof-sheets.” (Keynes,1936, p.xii).In the course of an extensive correspondence with J. Robinson in the months of...

Keynes’s very negative reaction to J. Robinson’s misuse of Keynes’s initial, beginning, introductory, preliminary exposition of liquidity preference in chapter 13 of the General Theory is explained by the fact that J. Robinson was repeating the same identical error made by R. Hawtrey, D....

J M Keynes could not respond to Ramsey’s 1922 Cambridge Magazine “article” because Keynes’s response would have required him to methodically show that every paragraph of Ramsey’s 3 page note didn’t make any sense at all due to the large numbers of errors of commission and omission....

The many, many myths created by Joan Robinson about J M Keynes and the General Theory, starting in the early 1930’s, have become embedded in the history of macroeconomics.These myths, such as the claim that Joan Robinson worked closely with Keynes on the writing of the General Theory, that R....

The first page of the 18 year old, F. P. Ramsey’s very short three page review, in the Cambridge Magazine issue of Jan., 1922, of Keynes’s A Treatise on Probability is comprised of claims about Keynes’s logical theory of probability that, to use L. J. Savage’s characterization of...

The mathematical equations Keynes wrote out in chapter 17, in explaining his generalization of his theory of liquidity preference, are simplifications of his conventional coefficient of weight and risk, c ,that were used by Keynes to integrate non additivity(V(a/h)=w)and non linearity{[1/(1+q)]}...

C. Misak’s 2020 biography of Ramsey has major errors in it, as regards the influence of Ramsey on Keynes with respect to the issue of probability, as well as her completely unsubstantiated retelling of the R B Braithwaite myth that an 18 year old Frank Ramsey showed up at Cambridge University...

Sraffa made a number of margin notes in chapter 17 in his copy of the General Theory .Contrary to Joan Robinson’s 1978 claim ,that Sraffa had uncovered logical and mathematical errors in Keynes’s liquidity preference theory of the rate of interest when he generalized his theory in chapter...

Teaching students about Keynes’s views on decision making ,expectations and rationality requires that the students have had a general introduction and overview of Parts II(interval valued probability), III(finite probabilities)and V(statistics, inexact measurement,and approximation, as...
