In a letter to F. Hayek dated Feb. 18, 1981, Paul Samuelson writes: "As a small sample of the _increacing_ esteem that your work is enjoying among modern economists, I enclose a xerox of a page from a recent lecture that I gave in Vienna and that is to appear in a book about Schumpeter (now that his Centennial is approaching)." The passage Samuelson refers to reads: "Schumpeter's final logic ought to have predisposed him to accord to Hayek the final victory over Lerner and Lange in the debate over whether a socialist state could play the game of parametric pricing. To find new _cost_ technologies and husband scarce knowledge as it is forever newly arriving, the letter of Walrasian equations achievable by Lerner-Lange auctioneers and bureaucrates serves as nothing compared to what Hayek's real life speculators and profit receivers are led by the invisible hand of market competition to contribute. I don't remember Schumpeter as pronouncing on this point, but on my reading it should be congenial to his _Weltanschauung_." Can anyone tell me the title of this essay, and were I might find it -- what the reference is for this paper. (also, is Samuelson correct that Schumpeter never 'pronounced on this point' -- and if Schumpeter was _not_ predisposed to accord final victory to Hayek, why might this have been?).
