Can wartime sacrifice be explained openly, rather than imposed through financial mechanisms the public scarcely notices? In this short 1940 review of Geoffrey Crowther’s Ways and Means of War, republished in 1997, Hayek praises an account of Britain’s economic choices that makes scarcity a matter of competing priorities: nearly anything may be attainable, but not everything at once. His approval sharpens into disagreement when Crowther suggests that reductions in private consumption cannot be openly faced. Hayek argues that citizens who understood the choice between taxation and inflation would prefer honest, explicit burdens. The review offers a compact encounter with his confidence in public understanding—and his insistence that economic leadership must explain the material cost of victory, not merely promise it.

Agreement with a book’s conclusions need not mean accepting its way of reaching them. In this brief 1940 review, reprinted with editorial notes in 1997, Friedrich August von Hayek praises Carl Snyder’s statistical defence of capitalism but questions its ambition to settle economic controversies through facts alone. For Hayek, rival theories can interpret the same evidence differently; Snyder’s own explanations depend on assumptions he leaves unstated. The sharpest example concerns “capitalism” itself: does it mean production using abundant capital, or free enterprise and private ownership? Evidence for one does not necessarily vindicate the other. The review offers a compact encounter with Hayek as a sympathetic critic, showing why precise concepts matter even when an argument supports conclusions he shares.

Market socialism arrived as a concession: Lange, Taylor, and Dickinson would keep state ownership yet let a central board set producer-good prices, instruct managers to equate marginal cost with price, and revise figures by trial and error as shortages and surpluses appeared. Hayek treats the maneuver as a mistaking of a static equilibrium model for a living process. Real economic life is ceaseless change—local scarcities, new methods, altered demand, particular machines and contracts—and by the time reports reach the authority and fresh prices issue, the relevant conditions have moved. His socialist manager, forbidden to undercut, speculate, or bid resources away, becomes a rule-following functionary who innovates only by persuading his superiors in advance, while central control of investment quietly restores the planning it claimed to escape.

If this will not lead to the worst forms of bureaucracy, I do not know what will.

Grant the planners their most ingenious model, and the calculation problem still bites—such is Hayek's verdict on competitive socialism in this German essay. Two earlier chapters of the debate may be closed, he allows: calculation in kind, and the fantasy of solving equilibrium's equations. The third, advanced by Oskar Lange, Fred Taylor, and H. D. Dickinson, keeps consumer choice and marginal-cost rules for managers while handing the pricing of producer goods to a central board that adjusts by trial and error. Hayek's objection turns on speed and knowledge: administered prices lag the daily flux of local conditions, made-to-order capital goods resist listing, and without free entry no cheaper method can underbid an incumbent. What survives is only quasi-competition—and, once investment is centrally directed, a standing threat to freedom.

Mit anderen Worten, wenn man wirklich alle diese Gleichungen wissen könnte, so wäre das einzige Mittel, das den menschlichen Kräften zu ihrer Lösung zur Verfügung stünde, die praktische Lösung zu beobachten, die der Markt vornimmt.

English translation: “In other words, even if one really could know all these equations, the only means available to human powers for their solution would be to observe the practical solution that the market carries out.”

Written in 1941 and reprinted here in 1997, Hayek’s wartime essay asks how Britain can act intelligently towards Germany without mistaking understanding for forgiveness. He traces a practical weakness in British policy to alternating admiration and hostility, reinforced by travel impressions rather than sustained study of German intellectual life. His distinctive concern is that German ideas already circulate within Britain and among its allies: refusing to study them does not prevent their influence, but makes it harder to judge. The essay connects this problem to concrete institutional remedies—university training for specialists and controlled scholarly access to current German publications. It offers a pointed account of why foreign knowledge requires interpreters able to notice developments beyond a government’s immediate wartime needs.

Admiration does not suspend criticism in Hayek’s English-language review of Ludwig von Mises’s Nationalökonomie, first published in 1941 and collected here in a 2013 reprint. Hayek finds the treatise’s strength in its integration of economic theory, the study of human action, and liberal social philosophy—but asks what such intellectual consistency costs when its author remains distant from contemporary economics. His reservations about interest theory and competition sharpen rather than cancel his appreciation. Particularly revealing is his response to Mises’s use of comparative costs to explain social cooperation, beyond international trade. This compact review lets readers see where Hayek supports Mises’s methodological independence, where he would argue differently, and why he distinguishes a developed liberal philosophy from a mere revival of laissez-faire.

Understanding Nazi Germany’s appeal need not mean excusing it. In this 1941 joint review, republished in 1997, Hayek welcomes two contrasting corrections to wartime perceptions: Paul Einzig’s exposure of Germany’s promised European order and C. W. Guillebaud’s account of social policies that helped secure German workers’ support. His sharper objection concerns what the reviewers’ subjects share: an apparent willingness to approve Nazi methods while condemning their purposes. Hayek asks whether comprehensive planning itself demands coercion, imposed hierarchies and leaders ruthless enough to enforce them. This brief review lets readers encounter that question in a concrete dispute over how to describe an enemy accurately—and how to judge seemingly desirable policies by the power required to carry them out.

Scientific expertise can explain general laws—but can it supply the changing, local knowledge needed to direct an economy? In this 1941 article, republished here in 1997, Friedrich August von Hayek addresses scientists and engineers drawn to centralized planning. He contrasts their ideal of deliberate construction with the coordination achieved through competitive prices, then asks what happens to intellectual freedom when one authority controls the resources needed to pursue competing purposes. His contention is that comprehensive planning concentrates power over ends, not merely economic means. The article offers a compact encounter with the connection between Hayek’s account of dispersed knowledge and his defence of liberty, while distinguishing policies that sustain competition or supplement its results from those that replace it with a single plan.

Whoever controls the means must decide which ends they are to serve.

An economy’s complexity seems to call for comprehensive direction; Hayek argues that it makes such direction impracticable. In this 1941 article, reprinted in 1997, he shifts attention from the planner’s objectives to the changing, local knowledge needed to use scarce resources well. A shortage of tin makes the problem concrete: how can users decide what to conserve, replace or recover without knowing why supplies have tightened? Hayek’s answer is that competitive prices coordinate adjustments without assembling everyone’s knowledge in one place. His argument depends on genuine competition, not simply the existence of markets, and his acceptance of wartime planning qualifies rather than abandons it. The article offers a compact account of why economic coordination involves discovering possibilities, not merely executing a known design.

Machinery and labour, Ricardo wrote, are in constant competition; from that maxim Hayek builds a tight reconstruction of the 'Ricardo effect,' the proposition that a general shift in wages relative to product prices alters the comparative profitability of methods combining labour and capital in different proportions. Writing in German in 1942, he makes turnover velocity—Umschlagsgeschwindigkeit—his gauge of capital intensity: a price rise adds the same margin at each sale, lifting the internal rate far more on fast-turnover, labour-heavy methods than on slow, machine-heavy ones. Firms redirect current outlay toward direct labour, even generating unemployment among machine-makers amid strong consumer demand. Testing the extreme of perfectly elastic credit and answering Kaldor and Wilson, Hayek insists that cheap money can obscure real scarcity but never abolish it.

Solange ungenützte Reserven von Arbeitern zu unveränderten Preisen zur Verfügung stehen, bedeuten unbegrenzte Geldmittel unbegrenzte Verfügungsmacht über die Produktionsmittel.

English translation: “So long as unused reserves of workers are available at unchanged prices, unlimited monetary means signify unlimited command over the means of production. But these are not the conditions relevant in a state of full employment, which will prevail near the peak of a boom.”

A prediction of centralized rule can warn against it—or encourage resignation to it. In this 1942 review, reprinted with editorial notes in 1997, Hayek tests James Burnham’s claim that capitalism must give way to a society governed by managers. He credits Burnham’s disturbing portrait while questioning the premises that make its arrival seem inevitable. His scrutiny of Burnham’s wartime forecasts and account of New Deal administrators also challenges the book’s claim to scientific detachment: historical prediction carries political sympathies of its own. This short review offers a pointed distinction between recognizing a possible future and accepting it as unavoidable, showing why Hayek could recommend Burnham’s book yet fear its influence.

However much one may disagree with the asserted inevitability of the developments the author sketches, its possibility and even likelihood cannot be gainsaid.

Between a rise in commodity prices and money wages that lag behind it lies a mechanism Hayek retrieves from Ricardo and sets at the center of capital and cycle theory. When labor grows cheaper relative to selling prices, the methods that pay are not the long, roundabout, machine-intensive ones but the quick-turnover processes that recover and reinvest their outlays fast—so a boom in consumer demand can perversely reduce demand for capital goods as firms work old plant harder, postpone replacement, and shift toward circulating capital. Reworking the wage-price relation through rates of turnover and internal rates of return, Hayek argues against treating the interest rate as the sole determinant of technique, and shows how credit expansion, once incomes and prices rise, pulls resources back toward shorter processes and throws the capital-goods trades into unemployment.
