J Smithin’s recent June, 2012 draft article, titled “A Rehabilitation of the Model of Effective Demand from Chapter 3 of Keynes’s General Theory (1936)”, provides an excellent summary of the error filled Post Keynesian D-Z model, as well as focusing on Patinkin’s partially correct...

Paul Davidson and his Post Keynesian-Institutionalist supporters have erred egregiously in basing their Ergodic-Non Ergodic theory of uncertainty and risk on the inductive fallacy of Conditional A priorism (Long Runism). The claim, made by Paul Davidson and his Post Keynesian-Institutionalist...

Backhouse and Bateman attempt to evaluate Keynes’s written words in the General Theory concerning his view of how useful mathematical analysis is in economics. They simply lack the basic tools needed to accomplish the task. This failure , however ,is not an isolated one. The same failure is...

J M Keynes engaged in correspondence over the IS-LM model contained in chapter 15 of the General Theory with R. Harrod and J Hicks in 1937. Keynes had no major objections. How could he? How could Keynes object to interpretations concerning his own model of IS LM in the General Theory, as laid...

Keynes’s concept of uncertainty from his 1908 Cambridge Fellowship dissertation to his death in 1946 was a range concept like probability-it could be measured on the unit interval between 0 and 1[0,1]. Uncertainty was an inverse function of what Keynes defined to be the evidential weight of...

In 1990,J. Runde presented a formal, mathematical representation of Keynes’s theory of evidential weight, as presented in chapters 6 and 26 of Keynes’s A Treatise on Probability ,as V(a/h)=V = K/(K+I).In 1999,A. Vercelli revised this to read as V =V(a/h) = K/(K+I), 0≤V≤1.We can identify...

All of J .M .Keynes's earlier 1933-1935 versions of his IS-LM(LP) model contained a serious inconsistency. These earlier models all incorporated both actual and expected outcomes in the same model. The units did not match up. Keynes solved this problem by himself by splitting off the D-Z model...

Shackle's attempt to completely redefine Keynes's definition of uncertainty in chapter 12 of the General Theory, which was that uncertainty is an inverse function of the weight of the evidence as discussed in chapters 6 and 26 of the A Treatise on Probability, as unknowledge (no knowledge of the...
