Michael Hudson Responds to Paul Krugman
[Watchingcbeams: Basically talking about how Economics can be logically consistent but not have any validity because it doesn’t match reality. Excerpted by a post by Michael Hudson starting with a quote from Economics Nobel Prize winner Paul Samuelson.]
“In pointing out the consequences of a set of abstract assumptions, one need not be committed unduly as to the relation between reality and these assumptions.”[Paul Samuelson “The Gains from International Trade,” Canadian Journal of Economics and Political Science, Vol. 5 (1939), p. 205. ]
This attitude did not deter him from drawing policy conclusions affecting the material world in which real people live. These conclusions are diametrically opposed to the empirically successful protectionism by which Britain, the United States and Germany rose to industrial supremacy.
Typical of this now widespread attitude is the textbook Microeconomics by William Vickery, winner of the 1997 Nobel Economics Prize:
“Economic theory proper, indeed, is nothing more than a system of logical relations between certain sets of assumptions and the conclusions derived from them… The validity of a theory proper does not depend on the correspondence or lack of it between the assumptions of the theory or its conclusions and observations in the real world. A theory as an internally consistent system is valid if the conclusions follow logically from its premises, and the fact that neither the premises nor theconclusions correspond to reality may show that the theory is not very useful, but does not invalidate it. In any pure theory, all propositions are essentially tautological, in the sense that the results are implicit in the assumptions made.”[William Vickery, Microeconomics (New York: 1964), p. 5.]
Such disdain for empirical verification is not found in the physical sciences. Its popularity in the social sciences is sponsored by vested interests. There is always self-interest behind methodological madness. That is because success requires heavy subsidies from special interests, who benefit from an erroneous, misleading or deceptive economic logic. Why promote unrealistic abstractions, after all, if not to distract attention from reforms aimed at creating rules that oblige people actually to earn their income rather than simply extracting it from the rest of the economy?

Why, for that matter, was I able to take 5 economics classes and not hear a fucking thing about political economy?...
