Böhm-Bawerk left no system encompassing the whole of economic theory; his greatness, Menger's obituary insists, lay in monographs that made sharply delimited problems illuminate the foundations of the discipline. From a life of legal study, three terms as Austrian finance minister, and a return to the Vienna chair, Menger draws out the scholar—the combative polemicist who gathered many opponents but not a single enemy. He traces the first inquiry into rights as pseudo-goods, then the lucid defense of subjective value and marginal utility against older cost and labor doctrines, and finally the crowning Geschichte und Theorie des Kapitalzinses. There the higher valuation of present over future goods, reinforced by the productivity of roundabout production, yields interest and its forms—a theory whose very controversy, Menger argues, confirmed its weight.

Seine Verdienste als Finanzminister würden allein genügen, ihm einen ehrenvollen Platz in der Geschichte Österreichs zu sichern.

English translation: “His merits as Minister of Finance alone would suffice to secure him an honorable place in the history of Austria.”

Little more than a signature survives here: an oblong-octavo album leaf inscribed by Eugen von Philippovich at Vienna on 6 April 1915, its value wholly bibliographical rather than textual. The catalogue record moves from author identification to physical description to provenance — a red round stamp of the J. K. Riess manuscript collection, an inventory number, and the punch-marks of an old binding. No argument, no doctrine: only attribution and the material history of collection and handling. As a wartime trace of one of Austria's leading national economists, the leaf documents how a fragment of hand becomes a collectible object, authenticated by stamps and stitching-holes rather than by anything its author chose to say.

Nur die Unterschrift.

English translation: “The signature only.—With the red round stamp of the "J. K. Riess Manuscript Collection", inventory no. "1086", and traces of holes from old binding.”

There is no such thing as social science, only social sciences whose circles overlap, so opens this lecture-essay, expanded from a 1911 Czernowitz address into a history and prognosis of an unruly field. Schumpeter's boldest rehabilitation is of eighteenth-century natural law, which he presents not as barren rationalism but as the matrix of modern sociology, economics, ethics, and legal theory, likening its role to what the Nile was for Egypt. Its one fatal error was to believe science could prove ideals, confusing explanation with the setting of aims. He reads the nineteenth-century reaction, from Romanticism and Carlyle to Comte and the historical school, as noisy discontinuity concealing cumulative continuity, governed by an impersonal Logik der Dinge that forces recurring problems on unwilling researchers. The future he foresees belongs not to grand synthesis but to specialized, statistically nourished theory.

Das war nichts anderes als Soziologie — in ganz demselben Sinn wie wir sie heute treiben, und von uns nur getrennt durch Fortschritte der Technik der Wissenschaft.

English translation: “That was nothing other than sociology — in exactly the same sense in which we pursue it today, and separated from us only by advances in the technique of science.”

Why does social science, unlike physics, offer no obvious course of study? Because it is young, institutionally unsettled, and forever invaded by the untrained, whose practical certainties blur its beginnings. Adapted from a 1910 Czernowitz lecture, this guide treats the discipline as a craft to be learned by handling facts, abstracting, clarifying concepts, and restraining political desire. Its four raw materials, everyday experience, history, ethnology, and statistics, yield nothing on their own, for the unanalyzed fact is mute; only theory, by decomposing phenomena into elements and tracing their tendencies, makes causality thinkable. Schumpeter warns against textbooks that leap from elementary theory to policy, urging students instead to reconstruct arguments and test concepts on concrete cases, taking Mill's education, Menger's Grundsätze, and Böhm-Bawerk's Kapital und Kapitalzins as models, and always keeping knowing and wishing apart.

Nach kurzer Übung tut man das alles unbewußt und sicher. Und dann ist man in den Sinn der Theorie eingedrungen. Dann kennt man die ganze Anlage ihres Gebäudes und weiß, was sie bieten kann und wo sie versagt.

English translation: “After a little practice one does all this unconsciously and with confidence. And then one has penetrated to the sense of the theory. Then one knows the whole layout of its structure and knows what it can offer and where it fails.”

Because restoring a customs wall between Austria and Hungary would revive decades of tariff conflict, Sieghart marshals the finance archives to defend the common market on the eve of the 1917 negotiations. His source-based history follows the Zwischenzoll-Linie, the intermediate customs line dividing Hungary from the hereditary lands, from enlightened absolutism through Joseph II's failed abolition to its removal in 1850 and constitutional confirmation in the 1867 Ausgleich. He shows the line perpetually entangled with unequal taxation, noble tax privilege, and the salt and tobacco monopolies, and charts how Hungarian opinion swung from Smithian free trade to Listian protectionism after the German Zollverein. Refuting Kossuth's prophecies of ruin with trade statistics, he concludes that the common market, not a tariff barrier, raised up both halves of the monarchy.

Der Zwischenzoll ist keine kommerzielle Maßregel, als welche sie niemand in Schutz nehmen würde, sondern nur ein schwaches Surrogat einer regelmäßigen Besteuerung, ein Ausweg, wodurch die Regierung die Schranken umgeht, welche ihr durch die fehlerhafte Verfassung gesetzt sind.

English translation: “The intermediate customs duty is not a commercial measure—as such no one would defend it—but only a weak surrogate for regular taxation, a shift by which the government circumvents the barriers set for it by the defective constitution.”

A polite acknowledgment that swells into a memorandum on statecraft, this wartime letter to Count Otto Harrach, unpublished until 1992, turns Schumpeter's praise of Harrach's composed detachment into a warning. Neutral initiatives, he argues, are not peripheral gestures but instruments capable of shaping the terms of peace, and no belligerent is so well advised as Austria to cooperate with them. He laments how alien the United States, financially and politically decisive, remains to Austrian diplomatic and finance-ministerial circles, drawing on his own earlier stay in America. The letter darkens toward its close: intensified submarine warfare, he fears, will alienate Washington and stiffen English resolve, and the deeper the gulf between the blocs grows, the more the Monarchy falls subordinate to Berlin, forfeiting the Western sympathies that might have served it at the peace.

Die Zeichen der Zeit sind düster.

English translation: “The signs of the times are gloomy.”

Loyalty to Germany without the appearance of vassalage: that is the knot this January 1916 letter to Count Otto Harrach tries to untie. Composed at Graz and unpublished until 1992, it contends that excessive deference to Prussia has weakened Austria's standing and disorganized its state-idea, alienating the non-German nationalities. The remedy is a program of specifically Austrian war aims that would make the Monarchy visible as an autonomous power and rally public opinion across national lines; Schumpeter treats opinion not as noise but as an instrument of state consolidation. Uninvolved in the Anglo-German antagonism, Austria could even speak a word of reconciliation with real authority. He weighs Habsburg openings in Asia Minor and Mesopotamia, urges conciliation rather than punitive centralism in the Bohemian question, and closes by tracing the Monarchy's every setback ultimately to financial causes.

Es kommt die Gefahr hinzu, daß Oesterreich zum Objekt von Compensationen für manche der kriegführenden Mächte werden könnte.

English translation: “There is the added danger that Austria could become an object of compensations for some of the belligerent powers.”

Schumpeter answers critics, Tugan-Baranowsky above all, who hold that marginal utility explains consumer prices but that wages, rent, and profit are dictated by social power. His governing thesis is that production and distribution are not two acts but one: every productive process is simultaneously a process of distribution, so incomes cannot be a whole first assembled and then divided by external force. Property, class, and legal coercion shape the conditions of the contest without replacing the price-theoretic account of income magnitudes. Wages he treats as the price of a productive service, derived through the entrepreneur from consumers' valuations, with marginal productivity offered not as moral justification but as analysis. The closing pages dissect artificial wage increases, insisting the question is meaningless until institutional conditions, time horizons, and market structure are specified.

Wie sich nun Kartenverteilung und Spieltechnik zueinander verhalten, so verhalten sich im Wirtschaftsleben Machtdiktat und Wirtschaftsgesetz.

English translation: “As the dealing of the cards relates to the technique of play, so in economic life do the dictates of power relate to the economic law.”

Böhm-Bawerk had claimed that even a solitary Robinson, storing grain and shaping tools, would already harbor the core of interest in the swelling value of goods prepared for the future. Sax sets out to refute that positive theory point by point—the temporal gap between need and provision, the alleged systematic underestimation of the future, the productivity of roundabout production—while preserving the marginal-utility theory from which Böhm-Bawerk wrongly thought it followed. His counter-concept is Wertperspektive: future goods carry lower present value because anticipated needs are felt more faintly, a valuation shift that mirrors planned welfare but generates no surplus. Interest, he concludes, is neither natural nor technical but a private-economic exchange gain, rooted in the unequal possession of present goods and absent alike from Robinson's island and a socialist commonwealth.

Die Wirtschaft Robinson’s kennt den uns geläufigen Zinsbegriff nicht.

English translation: “Robinson's economy does not know the concept of interest familiar to us.”

Educated people like to think themselves immune to advertising; the opening move here is to deny it, since publicity works beneath conscious scrutiny through repetition, imagery, and mere familiarity. Beginning from the premise that distribution completes what production only starts, this wide-ranging study treats advertising as a social power and anatomizes its media and economics—costs and prices, agencies and copywriters, the branded-goods system and retail substitution, mail-order houses, and the department store as a psychology of the female shopper. Mataja asks whether advertising is genuinely productive, refusing both blanket condemnation and the boosters' optimism, and closes on the state: unfair-competition law, the disfigurement of townscapes by posters, and the vexed question of an advertisement tax.

Die Reklame schafft einen Zustand, der einem Markte vergleichbar ist, auf dem die Waren zur Schau und Auswahl bereitgestellt werden, nur wirkt sie viel ausgedehnter, weil unabhängig von bestimmten Zeitpunkten und vom Erscheinen der Interessenten.

English translation: “Advertising creates a condition comparable to a market on which goods are set out for viewing and selection, only it operates far more extensively, since it is independent of particular points in time and of the appearance of interested parties.”

Scarcity alone cannot explain wartime inflation. In this 1916 lecture to the Hungarian Economic Society, Schlesinger tracks how war finance moves through the monetary circuit: reduced output lifts prices only once, but state spending met by newly created money returns as income, is spent again, and drives a progressive depreciation—an indirect tax that quietly strips a portion of purchasing power from every holder. Against this he sets the offsets, arguing that war loans neutralize nothing on their own but merely register private holders refraining from pressing their claims on goods. The agio, likewise, is no separate mystery but follows from domestic prices rising faster than foreign ones, with export prohibitions aggravating it and repatriated foreign assets braking the fall. Stabilizing the currency, he concludes, matters more than restoring any old parity.

Innerhalb einer kurzen Studie kann die wirtschaftliche Entwicklung nicht in all ihren Windungen verfolgt werden; darum kann ich hier nur ein stark stilisiertes Bild der Kriegswirtschaft bieten, dessen Konturen mit denen der Wirklichkeit in keinem einzigen Punkte übereinstimmen.

English translation: “Within a short study the economic development cannot be traced in all its windings; therefore I can here offer only a strongly stylized picture of the war economy, whose contours coincide with those of reality at not a single point.”

The death of an eighty-six-year-old sovereign in the third winter of war supplies the occasion, but the argument reaches past mourning: Franz Josef's authority, Sieghart contends, rested less on any particular deed than on a personality wholly fused with monarchy, duty, and the state. Printed as a separate offprint from the Neue Freie Presse, this eulogy defines the true monarch as one who stands above nations, classes, and parties, citing Andrássy, Kossuth, and the social democrats as proof of his impartiality. It reads the emperor's embrace of universal suffrage not as demagoguery but as an extension of equal civic obligation, dismisses talk of a court camarilla as nonsense, and treats popular reverence as capital bequeathed to the Crown.

Die Liebe des Volkes ist das Erbgut der Krone.

English translation: “The love of the people is the inheritance of the Crown.”
