Joan Robinson had no idea about what Keynes was talking about in the General Theory with respect to (a) Keynes's Aggregate Supply Curve of Chapter 20,which is a locus of all possible, multiple equilibrium results (Full employment, underemployment, involuntary unemployment), his Liquidity...

J. Muth's 1961 article on rational expectations was written without any knowledge on Muth's part about what a subjective theory of probability entails and is based on, or what an objective theory of probability entails and is based on. Muth's disbelief, that the individual, subjective...

J. M. Keynes versus D. Robertson in 1936-37 pits two opponents, one, J. M. Keynes, a highly skilled, sophisticated, mathematically advanced thinker against another, D. Robertson, who doesn't have even an elementary background in mathematics at the grammar school level. Basically, the...

The theory of rational expectations has no foundation in any extant theory of probability. None of the five existing theories of probability (Logical, Subjective, Classical, Propensity, and Limiting (relative) Frequency) lend any support at all to the Muthian conjecture that the subjective...

O Lange's failure to read chapters 20 and 21 of the General Theory accounts for his failure to use Keynes already worked out simplifications for the case where the Aggregate Supply Curve was infinitely elastic or had a horizontal segment. Chapter 3 of the General Theory only presents an outline...

J. Muth published a paper in 1961 in Econometrica that was incoherent and inconsistent because it was based on a hybrid amalgamation of directly conflicting Subjective and Objective theories of probability. Muth's hybrid amalgamation did not exist before 1961, in 1961, or after 1961. Muth jumps...

Keynes provided an overwhelming argument in his letter of August 27th, 1935 to Harrod that convinced Harrod twice to acknowledge that Keynes had made a “radical reconstruction” of the theory of the rate of interest. Special significance can be given to Keynes's three point post script in...
