Historical usefulness and theoretical failure coexist in Mises’s brief review of the sixth revised edition of Karl Helfferich’s Das Geld. He credits Helfferich with defending Germany’s gold currency and systematizing Ludwig Bamberger’s monetary teaching, but finds that the former disciple later attempted an untenable reconciliation with Georg Friedrich Knapp’s state theory of money. Mises locates this reversal between the first and second editions—not in the latest revision—and adds a pointed charge of neglecting monetary-theoretical literature, German as well as foreign. The review offers a compact example of his critical discrimination: monetary history and statistics can retain their value even when, in his judgement, the theory supporting them fails.

Not whether the state can decree a price, but what follows when a decreed price is meant to replace the one the market would form: that is the question this theoretical essay on official price fixing pursues within an order still based on private ownership. Mises distinguishes Ordnungstaxen, which hover near the market price and barely disturb it, from genuine controls that push maximum or minimum prices away from the unhampered level. A ceiling breeds shortage, hoarding, rationing, and finally compulsory production; a wage floor breeds unsold labor. Each isolated intervention forces a choice between retreat and further command. Price fixing, he concludes, is no stable third system between capitalism and socialism but cumulative social theory. Reprinted as Theorie der Preistaxen.

Der behördlich festgelegte Preis aber zerstört den Markt, auf dem Waren und Dienste gegen Geld gekauft und verkauft werden.

English translation: “The officially fixed price, however, destroys the market on which goods and services are bought and sold for money.”

After Bolshevik Russia retreated to the New Economic Policy, Mises saw the practical economics of the age settle on a regulated private-property order, neither laissez-faire nor outright expropriation. That third system is his target. Interventionism keeps ownership formal while replacing entrepreneurial calculation with isolated commands, and those commands, he argues, defeat their own ends: a price ceiling below the market breeds shortage, rationing, and finally compulsory production; a legislated or union-enforced wage above productivity turns frictional unemployment into a permanent institution. Corruption and evasion become structural supports rather than accidents. The postwar depression, on this reading, is not the crisis of capitalism but the crisis of interventionism, an order with no economic principle of its own, forced always to retreat or to advance toward socialism.

Entweder Kapitalismus oder Sozialismus; ein Mittelding gibt es nicht.

English translation: “Either capitalism or socialism; there is no middle way.”

The label social liberalism promised a synthesis; Mises reads it instead as an equivocal name for anti-liberal intervention. Framed as a review of the Brentano Festgabe, the essay treats that volume as evidence that Kathedersozialismus and the Historical School have exhausted their scientific content while keeping their political influence. His wedge is ownership of the means of production: liberalism, socialism, and syndicalism are rival institutional arrangements, not moral temperaments, and property as immediate control over production is indivisible. He counts the Methodenstreit settled against the historicists, denies that unions can raise labor's income as a whole by force without cost, and portrays Max Weber breaking painfully from Prussian statism toward liberal conclusions. Socialism, he insists, foundered not on resistance but on its own impracticability.

Nationalökonomische Erkenntnis führt notwendigerweise zum Liberalismus.

English translation: “Economic understanding leads necessarily to liberalism.”

Did the loss of an empire make Austria economically unviable? In this short 1926 address and accompanying discussion response, Mises separates the country’s diminished political territory from its prospects for recovery. He attributes fiscal stabilization to the end of subsidized government food purchases, monetary financing, and excessive expenditure, while warning that budget balance alone does not secure recovery. His reply to a question about Vienna sharpens the distinction: the city’s livelihood rested on industry, finance, and trade, not simply on imperial administration. Even as its financial role declined, he argues, commerce among the successor states offered new opportunities. The pairing captures Mises’s qualified optimism at a concrete postwar juncture, with domestic reform constrained by European trade barriers rather than national size alone.

Mises opens this brief review by contrasting two kinds of socialist historiography: scholarship absorbed in personal trivia and scholarship that clarifies economic ideas. Rodbertus’s letters to Schumacher, edited by Robert Michels and Ernst Ackermann, earn his approval for their attention to agricultural credit, rent, and the social question. His praise is not an endorsement of Rodbertus’s doctrines; it concerns what the correspondence and its supporting documents make intelligible. Even without Schumacher’s replies, Mises finds evidence illuminating both Rodbertus’s thought and Germany’s early imperial years. The review offers a compact instance of Mises judging historical scholarship by its explanatory value rather than dismissing it for its subject’s politics.

For Mises, the missing words in Keynes’s title are decisive: laissez-faire belongs with laissez-passer, the free movement of people and goods. This brief 1927 review of Keynes’s Das Ende des Laissez-Faire turns less on the proposed regulation of private ownership through semi-autonomous bodies than on protectionism and migration restrictions. Mises brings those omissions into focus through the predicament of displaced people and would-be emigrants barred from competing for work abroad. His challenge is pointed: can liberalism be blamed for distress produced, in his judgement, by its abandonment? The review offers a compact encounter with Mises’s insistence that property, trade, and human mobility cannot be assessed as separate freedoms.

A dictionary can mislead not only by omitting a term, but by explaining it too confidently. In this 1927 review of the English–German part of Hereward T. Price’s economic dictionary, Ludwig von Mises welcomes a useful reference while testing its translations against technical meaning and scholarly usage. A monetary “hoard” need not be secret; Tawney’s “acquisitive society” should not acquire extra moral condemnation in German. These concrete objections reveal Mises’s standard for specialist lexicography: provide the context ordinary dictionaries lack without turning a translation aid into an economics textbook. The review offers a compact encounter with the judgement required to translate economic language—especially where a seemingly helpful gloss narrows a disputed concept or strengthens an author’s evaluative tone.

Do inflation, tariffs, and cartels indict capitalism—or the policies imposed upon it? In this short 1928 review of Eduard Heimann, Ludwig von Mises disputes the move from identifying economic harms to assigning responsibility for them. He turns Heimann’s own concessions about governments, worker-supported parties, and academic economists against the claim that entrepreneurs bear the chief blame for inflation. For Mises, the disorders Heimann condemns arise from interventionism, not capitalism. A parallel dispute concerns whether a morally approved end can justify class struggle when Gospel injunctions prohibit its means. The review offers a compact encounter between Heimann’s religious socialism and Mises’s liberal economic criticism, sharpening the distinction between condemning an outcome and explaining its causes.

Buying Kant out of snobbery, paying extra to support a disabled veteran, or choosing a nearby shop for convenience: are these exceptions to economic explanation, or ordinary instances of valuation? In this essay, presented in its 1933 German republication, Ludwig von Mises argues that price theory must explain actual choices without first approving their motives. His distinctive target is not subjective value theory’s opponents but inconsistencies in its founders, Menger and Böhm-Bawerk, whose substantive achievements he defends. Mistaken beliefs, generosity, and national loyalty enter exchange through buyers’ preferences, not as departures from economic law. The essay makes precise why explaining a purchase differs from judging its purpose—and why monetary gain alone cannot define the conduct economics seeks to understand.

Money cannot simply be added to a theory of barter without changing what that theory explains. This is the central contention of Mises’s short article, which locates an unfinished task within subjective value theory: explaining not merely changes in money’s purchasing power, but how that purchasing power arises. Mises treats monetary economics as essential to understanding market fluctuations and economic calculation, rather than as a specialist appendix. Yet his case for theoretical advance also insists on continuity: he credits Ricardo, not himself or Cassel, with purchasing-power parity theory. The article offers a compact view of why Mises regards abstraction from money as a useful beginning—and an inadequate stopping point—for economic analysis.

Interwar enthusiasm for monetary planning fixed on two dreams: a money of stable purchasing power and a capitalism cleansed of the business cycle. Both exaggerate what policy can know and do. Purchasing power, Mises argues, cannot be measured objectively, since every index imports arbitrary weights, so Fisher's compensated dollar and Keynes's managed currency rest on pseudo-measurement. Gold he defends not as stable but as comparatively shielded from political hands. The second half builds the circulation-credit theory of the Konjunkturzyklus: bank-created fiduciary media push the loan rate below the natural rate, financing production that real saving cannot complete, so the crisis only reveals capital already misdirected. Cycles recur because opinion demands cheap money; his austere remedy extends the Currency School's rule to deposits and abandons the illusion that banking technique can conjure prosperity.

Erst die Konjunkturtheorie läßt uns in der wirren Fülle von Geschehnissen den Wellenzug der Konjunktur erkennen.

English translation: “Only business-cycle theory enables us to discern, amid the confused abundance of events, the wave-motion of the cycle.”
