Can an account of skilled labour improve Marxist value theory without answering objections to its foundations? In this brief 1906 review of H. Deutsch’s Qualifizierte Arbeit und Kapitalismus, Joseph A. Schumpeter carefully separates those judgements. He singles out Deutsch’s distinction between the teacher’s production of instruction and the apprentice’s productive consumption of it: learning becomes a separate process, not simply the teacher’s manufacture of skilled labour-power. Yet approval of this refinement does not imply acceptance of Marx’s premises, or of Deutsch’s prediction that complete mechanization will reverse the displacement of skilled workers. The review offers a compact example of Schumpeter’s critical discrimination: recognizing an advance within a theory while leaving its underlying vulnerabilities exposed.

Two ancient states, Meiji Japan and Porfirian Mexico, threw themselves into modernization within a single generation — an experiment, as the essay puts it, performed on the living body of an entire people. Inama-Sternegg sets the two side by side: railways, post, telegraph, banking, foreign trade, and above all merchant shipping. Mexico's advance under Díaz is real and, emerging from fifty years of civil war, deserving of admiration; but Japan rises faster, denser, and more intensely, building its own fleet where Mexico must ship through foreign carriers. The decisive line is drawn not by infrastructure but by sovereign economic agency — active trade conducted in one's own right rather than mere appearance on the world's markets. The parallel closes over the Pacific ports that might one day bind the two.

Mexiko erscheint wohl mit seinen Produkten auf den Weltmärkten, aber nicht im aktiven Handel.

English translation: “Mexico does appear with its products on the world markets, but not in active trade. Quite different has the economic situation in Japan always been. The country is in the highest degree active and enterprising.”

Written for the centenary of John Stuart Mill's birth, this commemorative essay measures a thinker by his continuing force rather than by novelty. Menger's Mill is a systematizer, not a revolutionary: in both logic and political economy he found abstract compendia on one side and a rich monographic literature on the other, and his gift lay in gathering, ordering, and returning scholarship to practical use. The System of Logic clarified the aims and errors of empirical inquiry, though Menger faults its overreach in extending natural-scientific method to the moral sciences. The Principles modernized English economics, carried it back from Ricardian abstraction toward Adam Smith, and drew money, foreign trade, colonization, and the social question into its frame. In the end Mill appears as neither forgotten classic nor revolutionary founder, but a philosophically trained mediator whose decisive move was to bring dispersed research into clear form.

Die Lebensarbeit John Stuart Mills war in erster Linie der Methodologie und der National-Oekonomie gewidmet.

English translation: “John Stuart Mill's life work was devoted primarily to methodology and political economy.”

When does an explanation of economic value become a prescription for economic justice? In this brief review of Johannes Leonhard, Schumpeter credits an account of utility and scarcity while disputing its claimed novelty after Jevons. His sharper objection concerns Leonhard’s move from explaining value to declaring production and consumption “correct” under conditions of freedom and mutual accommodation. Schumpeter insists that exact economic theory investigates facts rather than establishes ideals of justice. The review offers a compact instance of his critical discrimination: agreement with parts of a value theory does not mean accepting the social prescriptions attached to it.

To answer the socialist charge of exploitation with a theorem rather than a sermon—that is the ambition Schumpeter reconstructs in John Bates Clark's theory of distribution, presented here in deliberately uncritical exposition. In Clark's static state, abstracting from population growth, accumulation and technical change, free competition awards each factor the share of product it creates: to labor, capital and land its own. The argument turns on a distinctive capital concept—a durable, mobile fund embodied in perishable capital-goods, with land folded in—and on extending the law of diminishing returns from land to capital and symmetrically to labor, so that final productivity governs wages and interest alike. Schumpeter lets the assumptions show plainly, for the promised unity of wages, interest and rent depends on treating equal factor-units as equal productive contributions.

Clark's These ist nun die, daß in diesem statischen Zustande jeder Produktionsfaktor beim Walten freier Konkurrenz jenen Anteil am Produkte erhält, den er hervorbringt, daß also der Arbeit, wie dem Kapital und dem Lande, ihr, beziehungsweise sein Produkt zufällt.

English translation: “Clark's thesis is now this: that in this static state every factor of production, under the reign of free competition, receives that share of the product which it brings forth—so that to labor, as to capital and to land, its respective product falls.”

Should public fire insurance be judged by objections to state enterprise or by how insurers actually operate? In this brief 1906 review, Felix Somary praises Alglave’s comparative evidence and attacks French liberal economists for neglecting it. A telling distinction anchors the discussion: Alglave favours compulsory insurance for buildings, linked to building regulation, but voluntary coverage for movable property, where valuation and concentrated urban risks complicate provision. Somary’s accompanying assessment of German insurance-law debates reveals a related concern: specialized legal differences should not obscure the common basis of insurance contracts or displace economic analysis. The review offers a compact encounter with Somary’s critical priorities—administrative costs, institutional comparison, and the practical relevance of foreign experience to Austrian reform.

Diligently collected statutes do not, for Felix Somary, amount to legal scholarship. His brief 1906 review of Derblich’s Das österreichische Versicherungsrecht acknowledges the scarcity of earlier studies but refuses to let that excuse confused organization or inadequate analysis. Particularly revealing is his ridicule of a section on insurance in French literature, where maxims about protection against misfortune take the place of legal reasoning. The review offers a compact, sharp-edged example of Somary’s critical standard: even a difficult and little-studied subject demands systematic treatment, not merely accumulated materials and quotations.

When does a merchant’s experience become economic theory rather than advice to his son? In this short, caustic review of Richard Ehrenberg’s Das Haus Parish in Hamburg, Felix Somary challenges the promotion of biographical detail into scholarly explanation. Parish’s meals, guests and wine consumption exemplify what Somary regards as misplaced emphasis; injunctions to rise early and attend the exchange hardly establish an original theorist. Somary acknowledges Ehrenberg’s diligence as a collector of material while denying that accumulation alone constitutes analysis. The review offers a pointed dispute over what business biography can explain—and what, in Somary’s judgement, it must do to earn its claims to theoretical significance.

A balance sheet need not disclose the full extent of a company’s obligations. This is the point Felix Somary endorses in his brief 1906 notice of the commemorative volume for Reichsbank President Koch. While noting Rießer’s study of supervisory-board reform, he concentrates on Simon’s distinction between legal rights and liabilities and their recorded accounting representation. Giro liabilities provide the concrete example of what a balance sheet leaves undisclosed. The notice captures Somary’s interest in a precise boundary between law and economics: what accounts record is not necessarily everything a company owes.

Can gains for exporters justify an optimistic account of currency depreciation? In this brief 1906 review of Mitjavile’s study of Spain’s exchange-rate crisis, Felix Somary endorses a sharply different balance sheet: benefits for a narrow group set against dearer food, speculative commerce and heavier foreign debt payments. His judgement combines approval of Mitjavile’s fiscal explanation—government dependence on advances from the note-issuing bank—with appreciation of his caution about evidence. Tariff changes and returning colonial capital complicate even apparently striking exchange-rate data. The review offers a compact view of what Somary values in monetary analysis: attention to who gains and loses, institutional causes, and restraint in attributing economic effects.

A single-family house can offer worse sleeping conditions than a much-criticized tenement. In this 1906 review of a Bremen housing survey, Emil Lederer tests an architectural ideal against measurements: 44 percent of living rooms were no larger than eight square metres, and subdivision squandered already scarce space and air. His criticism targets the assumption that homeownership or small buildings necessarily produce healthy accommodation. Yet he also separates the improvement of housing from the explanation of rents, asking how tenants’ opportunities to buy constrain what landlords can charge. This brief review offers a concrete encounter with Lederer’s differentiated approach to housing reform: neither architectural labels nor a single account of speculation can explain both unhealthy rooms and costly shelter.

Reliable tables can outlast an unsuccessful introduction: that distinction anchors Felix Somary’s brief 1906 review of Wagon’s study of German joint-stock companies. Somary praises the annual financial tables, whose accuracy he tested by spot checks, while stressing their restriction to shares listed in Berlin. His interest is comparative rather than merely descriptive. Drawing on his own comparison with Austria, he singles out borrowing, higher average profits, and greater sensitivity to economic fluctuations among German companies. The review offers a compact example of how Somary evaluates statistical evidence: separating the quality of compilation from that of exposition, and asking what international comparisons the available figures can support.
