Why did his interest in the concept of spontaneous order and the history of the doctrine of unintended social consequences undergo very little develo… - Mark Blaug

Hayek's career raises many puzzles and sometimes takes on the appearance of an endless trail of unresolved or only partly resolved issues.

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.

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 to understand the process of competition, rather than the equilibrium end-state achieved by competition, we must begin by discarding such static reasoning as is implied by Walrasian GE theory. I have come slowly and extremely reluctantly to the view that they are right and that we have all been wrong.
