By 1934 the Grundsätze had grown almost impossible to obtain, even as the doctrines it launched spread across Europe—an obscurity Hayek's essay sets out to correct. His claim is that Menger did not merely share the marginal-utility discovery with Jevons and Walras but gave it the causal-subjective form from which Austrian method, value theory, price theory and monetary analysis all descend; the ideas Böhm-Bawerk and Wieser refined were at bottom Menger's own. Reading the Grundsätze closely, he shows economic activity as planning for the future, value as ordinal and quantity-dependent, productive factors priced by imputation, and money emerging through degrees of saleability. The Untersuchungen and the Methodenstreit with Schmoller become a defense of theory itself, grounded in an individualist method and an insight into the unintended order of social life.

But it is not unduly to detract from the merits of these writers to say that its fundamental ideas belong fully and wholly to Carl Menger.

Eugen Philippovich helped bring Austrian economic theory to German readers without abandoning his commitment to state-directed social reform. In this brief encyclopedia entry, first published in 1934 and reprinted here in 1959, Hayek explains why Philippovich’s reputation as a leading Austrian-school economist needs qualification. His influential textbook mediated between Austrian theory and the German historical school; his growing theoretical interests sharpened his criticism of reform proposals rather than ending his pursuit of an economy that was neither pure capitalism nor socialism. Hayek’s portrait offers a compact example of how transmitting a school’s ideas differs from belonging to it—and how theoretical scrutiny can coexist with a sustained political commitment to intervention.

One word has been stretched to cover a family of unlike acts—postponed consumption, idle money holding, capital maintenance, investment, taxation, and the 'forced saving' manufactured by credit creation—and the confusion, Hayek argues, has misled theories of capital, interest, and depression. Borrowing Röpke's classification, the article separates saving in natura from monetary saving, and voluntary individual thrift from corporate, compulsory, and credit-driven kinds, insisting that only one answers to ordinary usage. Against underconsumptionist explanations of slumps, it admits only special cases: hoarding, violent swings in the rate of saving, and credit that simulates saving and provokes malinvestment. Hayek traces the modern machinery—banks, securities, insurance—by which abstention becomes command over resources, and ends on the determinants of saving, from income security to the rate of interest.

The original meaning of the term saving, keeping or preserving something for future use, has gradually been extended to cover a number of different activities more or less directly connected with the original sense of the word.

The label “Manchester School” obscures the social concerns of the Manchester Statistical Society, Hayek argues in this 1935 review of T. S. Ashton’s centenary history. Investigations into mortality, railway labourers’ conditions and public health supply his concrete counterweight to that familiar image: here were researchers making the problems of industrial towns visible with scant resources. Hayek also reads Ashton as a theoretical economist alert to neglected predecessors. He singles out William Langton’s and T. H. Williams’s discussions of banking and trade cycles, asking whether their work helped shape Jevons’s thinking about cycles and capital. This brief review offers both a corrective to an intellectual stereotype and a carefully conditional lead for tracing the transmission of economic ideas.

Monetary nationalism promised escape: independent paper currencies, variable parities, and wide gold points that would seal a national economy off from foreign shocks. That promise, Hayek argues in this contribution to The Economist's debate over a future international order, is a delusion — real international adjustment cannot be evaded, only redirected, and discretionary depreciation breeds fresh conflict. Yet gold too is defective, since shifts in the demand for gold can inflict grave disturbances. His resolution treats fixed parity as a coordinating rule rather than mere attachment to metal, and proposes regulating gold-exchange reserves — central banks' realizable claims on other currencies — with a body such as the Bank for International Settlements varying the permitted ratio to offset gold's swings while leaving national reserves intact.

If an international standard is wanted, the gold standard, in spite of its undeniable defects, is the only practical choice.

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.
