Keynes made it clear to Townshend in their 1937-38 exchanges that Townshend's assessment, that Keynes ‘s theory of liquidity preference in the General Theory was based on Keynes's non numerical probabilities and weight of evidence(argument)analysis from the A Treatise on Probability, was...

The SIPTA (Society for Imprecise Probability,Theory and Application) view of Keynes's contributions to imprecise probability and application form a one-to-one, onto mapping from the claims of Henry E. Kyburg to what is accepted as being what Keynes's contribution was. Thus, if one is familiar...

Adam Smith and J M Keynes were both practitioners of virtue ethics who rejected Benthamite Utilitarianism. Their axiomatic foundations consist of the following three axioms only. The first is that probabilities are nonadditive, in general. Additivity is a special case. The second is that...

Economists, working in the Heterodox schools of economics, have severely confused Keynes's interval valued probability–weight of the evidence approach to decision making from the A Treatise on Probability, that Keynes integrated into the General Theory by way of his definition of uncertainty...

Adam Smith rejected the use of the mathematical laws of the calculus of probabilities because the basic information-data-knowledge provided in the real world of decision making did not allow a decision maker to specify precise, definite, exact, numerical probabilities or discover the probability...

Both Smith and Keynes have very similar conceptual approaches to what probability is, how it is used and applied and the areas of application in which it can aid a decision maker. They both accept an interval approach to probability based on inequalities and bounds versus ordinal, subjectivist...

Eight centuries ago, Thomas Aquinas clearly differentiated between probability and uncertainty in decision making. He viewed probability eclectically as having elements that involved propositions about events, frequency of events, and single events. He found an important role in his approach for...

B. Hill’s work on the “Confidence approach “ to decision making under uncertainty is based on the use of interval valued probability that is categorized as being imprecise, in contrast to the standard Bayesian requirement that a probability assessment must be precise. This requirement is...
