Some footnotes for economists
Economics as a science
Whether economics is a science is a question that would appear to a layman to economics to be esoteric and semantic, but it is of considerable interest to its professionals. It was claimed to be a science by John Stuart Mill, [1] - a claim that was later challenged by Lionel Robbins [2] and critically examined by Paul Samuelson [3]. It has been pointed out that many economic theorems do not satisfy Karl Popper’s criterion that, for a proposition to be considered scientific, it must be falsifiable [4]. The economic theory of utility, for example, yields tools that can be used in economic analysis rather than testable propositions. However, such tools can be used in the scientific analysis of economic activity, just as Euclid’s theorems can be used in the scientific analysis of physical phenomena. To the extent that the analysis yields testable propositions, it can nevertheless be considered scientific. But critics have claimed that the propositions of theoretical economics are seldom put to the test, and that even when the are, academic economists are apt to continue to put forward propositions that fail (The survival of the Hecksher-Ohlin theorem in face of Leontief's Paradox has been cited as an example)
