Capital may help produce more goods—but why should those goods be worth more than the inputs used to make them? This distinction drives Eugen von Böhm-Bawerk’s 1894 encyclopedia article, Zins. Testing rival explanations of interest against the problem of a persistent surplus of value, he argues that productivity alone cannot account for it. His own explanation turns on the premium placed on present goods over future goods, connecting loan interest with returns from production and durable property. The article offers a compact way to examine what competing theories must explain, while keeping depreciation, risk payments, and entrepreneurial profit distinct from pure interest. Its closing treatment of monetary abundance sharpens a further distinction: plentiful money is not necessarily plentiful real capital.

A skilled artisan earns four florins for relatively agreeable work; an ordinary laborer earns two for twice the hardship. In this 1894 reply to Auspitz, Böhm-Bawerk uses that contrast to separate two explanations too easily treated as one: prices tending toward monetary production costs, and wages compensating workers for subjective sacrifice. He accepts that labor’s disutility can influence prices, but disputes its universal operation when workers cannot freely adjust their hours. His distinctive emphasis falls on the value of money to the worker: utility enters the supply side as well as demand. The exchange offers a precise way to distinguish an observable cost-price relationship from the subjective mechanism proposed to explain it.

Agreement on marginal utility does not settle what capital is or why interest arises. In this 1895 review of Georg Sulzer, Eugen von Böhm-Bawerk examines a fellow marginalist’s attempt to organize economics around equilibrium. He admires Sulzer’s disciplined construction but questions whether its elaborate vocabulary identifies new economic quantities or merely renames familiar ones. The decisive disagreement concerns time: does the premium on present goods reflect psychological discounting alone, or must technical conditions of production also enter the explanation? Writing as a theorist whose own concepts Sulzer adopts and alters, Böhm-Bawerk makes these differences concrete through the treatment of savings, intermediate goods, and longer production periods. The review shows how shared foundations can sustain sharply different accounts of capital and interest.

An intended opponent can arrive independently at the theory he seeks to displace. That is Böhm-Bawerk’s verdict on Moriz Naumann’s account of value in this short 1895 review. He credits Naumann with genuine originality of reasoning even where his conclusions reproduce marginal-value theory—a distinction that makes the praise more than a reward for agreement. The limit comes at the relationship between costs and value: Böhm-Bawerk finds Naumann’s concept of “cost value” ambiguous and his criticism insufficiently grounded in his opponents’ actual arguments. The review offers a compact example of theoretical judgement that separates independent thought, novel results and accurate polemic, without allowing a serious objection to erase a work’s merits.

Interest is not the wage of the capitalist's pain. Replying to J. B. Clark - here in the German translation of the 1895 English essay "The Origin of Interest" - Böhm-Bawerk rejects the reading of his theory as a disguised abstinence doctrine and grounds interest instead in the objective superiority of present goods, given that fruitful methods of production are time-consuming. He defends the claim that interest can persist in a stationary economy, untied to fresh capital formation, and answers Clark's regress objection by distinguishing capital's absolute historical lineage from the average interval between original inputs and finished consumption goods. Turning Clark's water-mill and steam-mill example around, he shows that an equal financial return over a longer investment period implies greater technical productivity, confirming rather than refuting his analysis.

Professor Clark scheint ferner meine Zinstheorie für eine Art Abstinenztheorie zu halten.

English translation: “Professor Clark further seems to regard my theory of interest as a kind of abstinence theory.”

Against J. B. Clark's notion of a "true capital"—a permanent fund of productive wealth standing behind the changing machines and materials that compose it—Böhm-Bawerk mounts the first of his replies to American critics of the Positive Theory. He grants Clark much on abstinence and the trade-off between present and future enjoyment, but attacks the abstraction as a mystical double of real things: capital, he insists, has no causal existence apart from the concrete goods it comprises. He defends his phrase "goods of the same kind and number" as a logical control on time-preference, dismantles Clark's claim that true capital abolishes the production period—the tanner's leather is the true fruit of his labor, not the shoes he trades for—and warns that where words come to rule things, scientific clarity is irretrievably lost.

Nun, ich kenne kein anderes Kapital als die konkreten Güter, die dasselbe zusammensetzen, und ich glaube: auch die Welt der Tatsachen kennt kein anderes.

English translation: “Now, I know of no capital other than the concrete goods that compose it, and I believe that the world of facts likewise knows of no other.”

When General Francis A. Walker charged that the Austrian history of interest theories had been ungenerous and pedantic, Böhm-Bawerk answered with a four-part rejoinder that turned the attack back on productivity doctrine itself. Across questions of historical criticism, capital as a factor of production, the sources of interest, and the relation of production to value, he insists that noticing a surplus - a machine costing fifty dollars that yields fifty-three - is not yet explaining it. The decisive puzzle is why competition fails to bid up the instrument's value or bid down the product's price. Walker's appeal to scarcity and high demand, he argues, names conditions without supplying the mechanism, and interest can be grasped only through the premium present goods command over future ones. Time, not production, proves the more fundamental category.

Und die berühmte und weit verbreitete Abstinenztheorie ist ebenfalls nur eine Erfindung meiner kritischen Phantasie.

English translation: “And the famous and widely disseminated abstinence theory is likewise only an invention of my critical fancy.”

Saving appears here not as a by-product of capital formation or consumption, but as a subject deserving its own economic analysis. In this brief 1896 review of Giovanni Montemartini’s Il risparmio nella economia pura, Böhm-Bawerk endorses Karl Menger’s distinction between visible technical processes and the less visible decisions that direct the movement of goods. He welcomes Montemartini’s attempt to replace scattered treatments of saving with a systematic inquiry. The review offers no account of the book’s particular conclusions; its interest lies instead in Böhm-Bawerk’s judgement of what merits theoretical attention, and why scholarly command and critical precision matter when opening a neglected field.

Böhm-Bawerk’s brief 1896 review values a biography of Proudhon for more than its record of outward events: Karl Diehl’s concluding volume connects the development of Proudhon’s writings with personal experience and political upheaval. The review offers a compact glimpse of Böhm-Bawerk’s standards for intellectual biography, especially his appreciation of Diehl’s treatment of the February Revolution. He also registers Diehl’s contrast between Proudhon’s idealism and Marxism without independently arguing that distinction. His warm endorsement of the completed study is a judgment on historical scholarship, not an endorsement of Proudhon’s doctrines—a useful distinction for readers interested in how an economist assessed the scholarly reconstruction of socialist thought.

Can an economics textbook remain accessible without stopping at surface explanations? In this 1896 review of the first part of N. G. Pierson’s Leerboek der Staathuishoudkunde, second revised edition, Eugen von Böhm-Bawerk makes that distinction the basis of his praise. He values Pierson’s ability to identify the scientific problem behind a topic and connect complex phenomena to their underlying causes within a few lucid remarks. His enthusiasm becomes more qualified when considering Pierson’s decision to place exchange value, rent, interest, and wages before production: an instructive experiment, not a definitive solution. This brief review offers a concrete glimpse of Böhm-Bawerk’s standards for economic teaching, distinguishing clarity from simplification and theoretical explanation from the practical ordering of a textbook.

An opponent’s portrait can become a school’s accepted identity. In this 1896 review of Richard Schüller’s Die classische Nationalökonomie und ihre Gegner, Böhm-Bawerk traces a pointed reversal: Smith’s reductive account of mercantilism was followed by the historical school’s reductive account of Smith and the classical economists. He welcomes Schüller’s textual evidence against familiar accusations—that the classics recognized only self-interest, ignored historical differences, and rejected state intervention unconditionally. His defence concerns the accuracy of their reception, not the truth of every classical doctrine. Distinguishing Schüller’s corrective scholarship from his sharp polemics, the review offers a compact account of how disciplinary disagreements harden into inherited descriptions, and what returning to original texts can unsettle.

Industrial experience and sympathy for workers are central to Böhm-Bawerk’s recommendation of William Smart’s Studies in Economics. In this short 1896 review, he singles out the wage essays: Smart’s earlier life as a manufacturer and continuing contact with industry in Glasgow give his theoretical inquiries an unusually direct grounding. Böhm-Bawerk offers no detailed assessment of Smart’s conclusions; instead, he explains why this combination of analytical clarity, practical knowledge, and concern for workers deserves attention. The review provides a compact glimpse of what he values in economic writing, particularly when its subject is the livelihood of the largest class of fellow citizens.
