Summary

Schumpeter’s 1927 introduction to Wicksell’s final essay is both homage and intervention. The Archiv republishes a Swedish article because Wicksell has not been adequately absorbed by the profession and because the essay, nominally a review of Bowley’s textbook, contains understated theoretical results. Schumpeter’s central claim is that Wicksell matters not as founder of a school but as a living workshop of modern analysis: a modest, mathematically trained thinker who joined Walrasian equilibrium, Böhm-Bawerkian capital theory, marginalism, and monetary theory to unresolved problems.

Und es ziemt sich, in diesem Fall von unserer Übung noch weiter abzuweichen und des Mannes und seines Werkes mit einigen Worten zu gedenken, weil seine Bedeutung im weiteren Kreise der Fachgenossen noch nicht ausreichend gewürdigt, seine Botschaft noch nicht ausgeschöpft wird.

English translation: And it is fitting, in this case, to depart from our practice even further and to commemorate the man and his work with a few words, because his significance is not yet sufficiently appreciated in the wider circle of colleagues in the field, his message not yet exhausted.

The first section explains this neglect through character and style. Wicksell avoided self-advertisement, credited predecessors scrupulously, and wrote without polished closure. For Schumpeter, this deficiency is precisely the value of reading him: the reader sees questions, obstacles, and doubts, not merely finished propositions. The tribute turns Wicksell’s modesty into an epistemic virtue.

Auf allen Gebieten ist das selten. Wie selten es ist, das sieht man am besten, wenn uns ein Meister das Räderwerk des forschenden Geistes im einzelnen zeigt, wie das Ernst Mach für die Mechanik und die Wärmelehre getan hat.

English translation: In every field this is rare. How rare it is one sees best when a master shows us in detail the machinery of the researching mind, as Ernst Mach did for mechanics and the theory of heat.

Schumpeter’s portrait is also biographical and critical. Wicksell’s radicalism, imprisonment, and late professorship show an ethical intensity that hurt his influence; his marginal-utility economics therefore refutes the claim that marginalism is inherently justificatory. Like Marshall, he reached economics through social and moral impulse rather than disciplinary careerism. Yet Schumpeter insists that the future of economics belongs to those who command mathematical forms of thought.

Wer heute das Gebiet ökonomischer Analyse betritt, muß damit rechnen, daß er eine Zeit erlebt, in der es ganz ohne Kenntnis der Denkformen der höheren Mathematik unmöglich sein wird, in Fragen unserer Wissenschaft mitzureden.

English translation: Whoever today enters the field of economic analysis must reckon with living to see a time in which it will be impossible, entirely without a knowledge of the forms of thought of higher mathematics, to have a say in the questions of our science.

Schumpeter then situates Wicksell historically with deliberate restraint. Jevons, Walras, Menger, Marshall, Clark, Böhm-Bawerk, and Wieser preceded him; Ohlin is corrected for overstating Wicksell’s role in marginal productivity theory. Wicksell’s achievement was synthesis and extension: he inserted a Böhm-Bawerkian capital analysis into a broadly Walrasian system and advanced equilibrium, price, public finance, and especially money-and-credit theory. The governing principle is that innovation begins from inherited instruments.

Und schon dieses Buch zeigt, daß er den Bogen des Odysseus spannen konnte und nebenbei auch, daß wirkliche Kraft bei uns, so gut wie in jeder andern Wissenschaft auch, stets vom Vorhandenen ausgeht und wahre Originalität nur am Vorhandenen fruchtbar werden kann.

English translation: And this book alone shows that he could bend the bow of Odysseus, and, incidentally, that real strength with us, just as in every other science too, always proceeds from what already exists, and that true originality can bear fruit only in relation to what already exists.

His generosity also lets Schumpeter attack school labels. Wicksell can be placed beside Austria, Lausanne, Marshall, or Clark because, for serious theorists, the supposed divides are secondary; mathematics is not a faction but a way through analytical thickets.

Die Grundlagen sind bei allen dieselben, wenigstens tatsächlich, wenn auch nicht immer offiziell.

English translation: The foundations are the same for all, at least in fact, if not always officially.

The second section turns from homage to Wicksell’s Bowley review. Bowley’s importance lies in the fact that a leading empirical statistician recognizes that unemployment, wages, trade, and income distribution require pure theory. Wicksell’s review is conscientious, even pedantic, yet contains new results he characteristically understates. Schumpeter uses the commentary as a methodological lesson: terminological slips matter because untrained readers convert doubts into objections. He clarifies Bowley’s “individuals” as market parties, Wicksell’s “numerous monopolists” as limited competition, and discusses increasing returns, Pigou’s marginal supply prices, and indifference curves. Historical precision matters too: the modern use of indifference lines as objective data belongs more to Pareto than Edgeworth, and it does not require treating marginal utility as discarded metaphysics.

The climax is price formation where one market side is held by a few large agents: limited competition or multiple monopoly. Schumpeter stresses that most actual transactions fall between perfect competition and complete monopoly; if theory only handles those polar cases, its apparatus fails.

Mit Recht sagt Wicksell, daß dieses Problem »brennend« sei.

English translation: Wicksell rightly says that this problem is »burning«.

Wicksell’s Cournotian treatment is therefore, for Schumpeter, the essay’s decisive contribution and a starting point for further work, including the problem of universal monopoly.

Die in diesen Punkten in der Tat nicht ganz befriedigenden Darlegungen Bowleys kritisierend hat uns Wicksell Saatkörner hinterlassen, die reiche Ernte bringen können, wenn man sie nur zu nehmen versteht.

English translation: In criticizing Bowley's expositions—in these points indeed not entirely satisfying—Wicksell has left us seed-grains that can yield a rich harvest, if only one knows how to take them.

Yet Schumpeter ends by pressing beyond Wicksell. Bilateral monopoly—such as unions and employer organizations—need not be pure indeterminacy if each side knows the other’s demand curve, acts under mutual regard, and contracts for a period. Such equilibrium is less secure than competitive equilibrium but still theoretically determinate. The broader relevance of the introduction lies here: it points toward a general price theory in which perfect competition is not the norm but one limiting case.

Noch erhöhte wissenschaftliche Bedeutung gibt ihm aber der Umstand, daß es über sich selbst hinausweist auf eine allgemeinere Preistheorie, innerhalb der die Hypothese der freien Konkurrenz nur einen Sonderfall darstellt, ähnlich wie es eine allgemeine Theorie des Wechselkurses gibt, von der die Theorie der Gestaltung der Wechselkurse bei allseitiger vollständiger Goldwährung ein Sonderfall ist.

English translation: But still greater scientific significance is lent to it by the circumstance that it points beyond itself toward a more general price theory, within which the hypothesis of free competition represents only a special case, just as there is a general theory of the exchange rate, of which the theory of the formation of exchange rates under a universal, complete gold standard is a special case.
