What would count as reliable evidence about Soviet economic planning? In this 1935 foreword to Boris Brutzkus’s Economic Planning in Soviet Russia, reprinted in 1997, Hayek argues that neither political detachment nor firsthand observation is enough. An investigator must distinguish specifically Russian conditions from effects of the economic system—and understand what planning is supposed to accomplish. His endorsement of Brutzkus turns on this combination of theoretical clarity, knowledge of Russian agriculture, and access to internal Soviet discussions rather than material prepared for foreign audiences. The foreword offers a compact view of Hayek’s standards of economic inquiry: readers can see why he regards Brutzkus’s early analysis and subsequent historical investigation as mutually reinforcing, while recognizing that the detailed evidence belongs to the book he introduces.

How can an economy suffer a shortage of capital while capital goods stand unused? In this 1935 essay, Hayek locates the contradiction in investment plans whose completion requires resources consumers are unwilling to release. Credit expansion, he argues, can make long-term commitments appear viable without any corresponding willingness to postpone consumption. The resulting crisis exposes incompatible expectations, not merely isolated entrepreneurial mistakes. The essay is also an exercise in theoretical revision: Hayek questions his earlier reliance on changes in an aggregate capital stock and turns instead to the timing of production and consumption. Readers can follow how this shift connects monetary disturbances to unfinished investments—and why explaining how prices shape expectations remains, by Hayek’s own admission, an unresolved task.

For decades socialism was argued as a question of justice, distribution, and whether citizens would supply the needed virtue—never as a question of whether central direction could actually work. Recovering the distinction between the economic problem, allocating scarce means among rival ends, and the merely technical problem of achieving one given end, Hayek shows that even wholly loyal officials would still confront the need to compare competing uses of resources, a comparison capitalism performs through prices no single mind computes. He traces the long eclipse of this insight through the historical school's suspicion of abstraction and Marxism's faith in historical inevitability, then through marginal utility theory to Mises's decisive claim: without money prices for the means of production, a planning authority has no rational way to calculate at all.

THERE is reason to believe that we are at last entering an era of reasoned discussion of what has long uncritically been assumed to be a reconstruction of society on rational lines.

Long treated as a moral demand or a rational blueprint for society, socialism must instead be judged, Hayek insists in this German-language essay, by whether it can actually coordinate scarce means among competing ends. The distinction he presses is between technical and economic problems: a technician optimizes toward a given end, but a society must weigh forgone alternatives, and only money prices for intermediate goods, capital, and factors of production make such comparison possible. Tracing the debate from Gossen, Pierson, and Barone to its decisive formulation by Mises in 1920, he shows why marginal utility theory made the calculation problem unavoidable, and why historicism and Marxian anti-utopianism had long concealed it. The burden of proof, he concludes, falls squarely on socialism's advocates.

In einer reinen Verkehrswirtschaft denkt niemand über irgendwelche wirtschaftlichen Probleme nach, außer über seine eigenen.

English translation: “In a pure exchange economy, nobody reflects on any economic problems other than his own.”

Few concepts are invoked so often and interrogated so rarely, Hayek observes, as a 'constant amount of capital'—and once change is admitted, it dissolves. Maintaining capital, the essay shows, cannot mean preserving identical goods or an unchanged money valuation; it is a derivative rule for avoiding unintended encroachment on future income. Sparring with Pigou over physical-loss and index-number criteria, Hayek holds that foreseeable obsolescence must be amortized like ordinary wear, that windfall profits are not freely consumable income, and that no expectation-free standard of 'net' saving or investment survives in a changing world. Foresight thus moves to the centre of capital theory, and the warning carries into monetary policy: in a boom, rising asset valuations mistaken for income invite the quiet consumption of capital itself.

It is not likely that in the whole field of economics there are many more concepts which are at the same time so generally used and so little analysed as that of a “constant amount of capital.”

A factory can increase output without putting scarce resources to their best use. This distinction drives Hayek’s 1935 concluding essay in Collectivist Economic Planning, where he tests socialist proposals against the practical demands of economic calculation. His objection to mathematical planning is not that equilibrium cannot be described, but that its equations presuppose detailed, continually changing knowledge: even technically identical goods differ economically by location, age, and availability. Proposals retaining competition under state ownership sharpen another question—who allocates capital and bears the consequences of mistakes? The essay shows why Hayek treats calculation as a problem of institutions and responsibility rather than arithmetic alone. It also directs criticism at capitalist monopolies that preserve investors’ capital at consumers’ expense, distinguishing his defence of competition from a defence of existing businesses.

What makes a bibliography trustworthy beyond the breadth of its coverage? In this 1936 review of Henry Higgs’s Bibliography of Economics, 1751–1775, Hayek welcomes an undertaking built on Foxwell’s extensive collections, then tests its reliability against particular entries. Harris’s two-part work on money receives misleading records; Raper reappears as “Roper”; a nineteenth-century edition of Prussian archival documents finds its way under 1769. These are not interchangeable complaints: they expose problems of attribution, identification and chronological scope. The brief review offers a concrete encounter with Hayek as a critical reader of scholarly reference tools, showing why admiration for a bibliography’s comprehensiveness need not entail confidence in its details.

A handsome reprint need not be the most useful one for scholars. In this brief 1936 review, Hayek welcomes the republication of W. A. Shaw’s collection of English monetary documents but questions the cost of its sumptuous production. His judgement distinguishes the bimetallic controversy that shaped Shaw’s 1896 selection from the documents’ continuing value—notably Newton’s reports as Master of the Mint, otherwise unavailable in print. The review offers a compact glimpse of Hayek as a reader of historical economic sources, attentive both to the interests governing their selection and to the practical conditions under which scholars can consult them.

A useful biography can still fail its subject as an economist. In this brief review of D. B. Copland’s two lectures on W. E. Hearn, Hayek welcomes new information about Hearn’s Australian career but finds his economic thought poorly served. Hayek values Hearn’s original observations and lucid expression; he wants them examined in relation to the teaching at Trinity College and their influence on later writers. His objection is pointed: Copland makes Hearn a vehicle for contemporary Australian economists’ views. The review offers a compact glimpse of Hayek’s judgement of Hearn—and of the distinction he draws between recovering a thinker’s contribution and recruiting him for present purposes.

An exhaustive account of Soviet institutions can still leave the decisive economic question unanswered: how does a plan establish which uses of scarce resources are most worthwhile? In this 1936 review, reprinted with editorial notes in 1997, Hayek praises Sidney and Beatrice Webb’s investigative achievement while challenging their confidence in a deliberately constructed, “scientific” civilization. His objection is not that Soviet workers lack incentives; he credits competitive wages and piecework with real successes. Rather, he asks what replaces the coordinating function of profits and prices. Bookkeeping, he argues, cannot test efficiency when its figures fail to reflect relative scarcity. This compact review makes visible the distinction between mobilizing resources and allocating them effectively—and the limits Hayek finds in treating social organization as an engineering problem.

"Overcapacity" is less an industrial fact, this 1936 lecture contends, than a political dogma — the belief that competition either adopts new techniques too slowly or squanders capital by scrapping serviceable machines. Hayek dissolves the charge by separating technical from economic capacity: a machine may still run yet be worth nothing, because new capital does not duplicate the old but economizes on labor and materials, freeing them for use elsewhere. Old plant should survive only while the new method's total cost exceeds its bare operating cost. From this he attacks "capital preservation" as a false end, whether protecting railways against motor traffic or shielding state assets, and ridicules forced standardization for letting an authority decide what consumers ought to like. Idle plant, he adds, may signal a scarcity of capital, not a surplus.

Die Normierungsfanatiker begeben sich da auf ein außerordentlich gefährliches Feld, und ich wenigstens kann mich nicht für die Idee begeistern, daß jemand anderer für mich entscheiden soll, was mir gefallen oder schmecken soll und was nicht.

English translation: “The fanatics of standardization are venturing here onto extraordinarily dangerous ground, and I, at least, cannot warm to the idea that someone else should decide for me what I ought to like or find tasty and what not.”

Frank Knight had reduced capital to a self-perpetuating fund — permanent, self-maintaining, its replacement a mere matter of technology. Against that "mythology" Hayek defends the Austrian insight that capital is no substance behind things but a structure of heterogeneous, perishable goods whose replacement must be economically explained. He concedes that Böhm-Bawerk's single "average period of production" oversimplifies, yet insists Knight's alternative is worse, since it cannot explain how limited capital restricts the choice among known methods. More capitalistic production means investing some factor for longer; a given stock of capital goods offers not one subsistence fund but many possible time-shaped income streams. What matters are prospective returns, not original factors — and the doctrine collapses only under the fiction of perfect foresight.

The theory looks forward, not back.
