Modern Austrian economists go so far as to suggest that the Walrasian approach to the problem of multimarket equilibrium is a cul de sac: if we want … - Mark Blaug

The Lange idea of managers following marginal cost-pricing rules because they are instructed to do so, while the central planning board continually alters the prices of both producer and consumer goods so as to reduce their excess demands to zero, is so administratively naive as to be positively laughable. Only those drunk on perfectly competitive, static equilibrium theory could have swallowed such nonsense. ... in all the recent calls for reform of Soviet bloc economies, no one has ever suggested that Lange was of any relevance whatsoever. And still more ironically, Lange’s “market socialism” is, on its own grounds, socialism without anything that can be called market transactions.

Nothing is more difficult than to turn and entire discipline around, asking itself to jettison its own history over the last 200 years.

The history of economic thought is irrepressible. It would survive even if it were banned … it would be carried on in secret in underground organizations. Many economists denigrate the history of economics as mere antiquarianism but, in fact, they have deluded ideas about the history of their own subject. After all, whenever anyone has a new idea in economics, whenever anyone hankers to start a new movement or school of thought, what is the first thing he or she does? Why, it is to rummage the attic of past ideas to establish an appropriate pedigree for the new departure. … Smith, Ricardo, Marx, Marshall and Keynes all drew on the history of economics to show that they had predecessors and forerunners; even Milton Friedman, when he launched the monetarist counterrevolution against Keynes, could not resist the temptation to quote David Hume over and again. The history of economic thought cannot be abolished and, were its study declared illegal, it would be studied in basements behind locked doors.
