It was not the gold standard's international character that doomed interwar monetary order, Hayek argues, but a world unwilling to run a genuinely international money. Delivered as five lectures at Geneva in 1937, his case defines monetary nationalism as the doctrine that a nation's share of the world's money should be governed differently from the money of its own regions, and traces the resulting instability to national reserve systems perched atop small gold holdings. Variable exchange rates, he contends, magnify rather than tame short-term capital movements, breeding capital flight, trade restriction, and fresh political friction. Under a truly homogeneous international money, national denominations would matter no more than differing units of measurement, and until some international authority exists to supply it, even a mechanical gold rule is preferable to independently managed national currencies.

The Monetary Nationalists condemn it because it is international; I, on the other hand, ascribe its shortcomings to the fact that it is not international enough.

Can removing mathematical notation make price theory harder to understand? In this short review of E. H. Phelps Brown’s The Framework of the Pricing System, Hayek praises the book’s coherent exposition while questioning its approach to beginners. His objection is not to mathematical economics but to presenting functional dependencies without the tools that make them intelligible. Calculus might better prepare some students; diagrams could clarify substitution and prevent confusion with older utility concepts. The review offers a focused encounter with Hayek as a reader and teacher of economic theory, distinguishing agreement with an argument from confidence in how it is taught.

New documents can unsettle an intellectual biography without yet supplying a better one. In this 1938 review of William Robert Scott’s Adam Smith as Student and Professor, Hayek welcomes evidence that clarifies Smith’s economic thinking before his journey to France and challenges received assumptions about physiocratic influence. Yet archival abundance is not enough: poor cross-references, hard-to-read facsimiles and missing bibliographical guidance leave readers to perform too much of the historian’s work. Hayek’s distinctive concern is the distance between establishing evidence and explaining what it changes. This short review shows him weighing discoveries about Smith against the scholarly presentation needed to make their implications intelligible—and asking for a rewritten biography rather than merely an enlarged documentary record.

Assurances that economic planning can coexist with freedom are not explanations of how it would do so. This distinction drives Hayek’s short 1938 review of Findlay Mackenzie’s symposium, whose informative discussions of particular policies he distinguishes from its weaker treatment of comprehensive planning. His criticism draws on tensions within the volume itself: contributors repeatedly address liberty and democracy, while the editor concedes that war could disrupt a planned society more severely than one allowing continuous private adjustment. Hayek turns that concession against the argument for extending planning in preparation for defence. The review offers a compact encounter with his critical method: acknowledging useful scholarship while testing whether advocates have answered the institutional difficulties their own discussions expose.

The vocabulary of freedom, Hayek warns, has been turned inside out — "liberalism" now names the restrictions that collectivists promise will free men from want. Written on the eve of war and anticipating The Road to Serfdom, this Chicago pamphlet argues that comprehensive planning threatens the liberties it claims to enlarge. Its logic is institutional, not conspiratorial: directing all economic life requires agreement on a ranked scale of social ends that plural societies simply lack, so planners must impose values and then manufacture belief in them. Prices, by contrast, combine dispersed knowledge no single mind commands. Because whoever controls the means controls the ends they serve, economic dictatorship cannot stay merely economic — propaganda and the suppression of dissent become essential parts of the system. Only competitive capitalism, he contends, keeps democracy from having to decide everything, and so from destroying itself.

Freedom and liberalism have become terms that are used to describe the exact opposite of their historic meaning.

Agreement that society should be more just does not settle whose needs should take precedence when resources are scarce. In this 1938 article, republished in 1997, Friedrich August von Hayek makes that gap central to his critique of comprehensive economic planning. He acknowledges the socialist ambition to enlarge freedom, but argues that centrally directing individual activities requires a ranking of purposes on which democratic citizens cannot agree. Delegating decisions to experts cannot resolve this conflict of values; in his account, it instead encourages unchecked authority and the suppression of dissent. The article offers a pointed connection between economic allocation and intellectual liberty: readers can examine why Hayek regards disagreement not as an obstacle to social reason, but as one of its necessary conditions.

Theoretical disagreement need not erase intellectual gratitude. In this brief 1939 review of John Bates Clark: A Memorial, reprinted with editorial annotations, Hayek recalls Clark’s generosity toward younger scholars while rejecting his reduction to a believer in natural economic harmony. Rather than defend marginal productivity analysis at length, he offers a personal recollection and a revealing document: Clark’s 1890 letter to Robert Zuckerkandl, describing his initial belief that he had independently discovered principles of value and acknowledging Austrian predecessors. The letter gives substance to Hayek’s account of cordial relations across the capital-theory controversy. This small review preserves a precise glimpse of how recognition, mentorship and disagreement could coexist among economists.

A peace settlement cannot credibly restrain defeated states if the victors refuse equivalent restraints themselves. In this 1939 letter to The Spectator, republished in 1997, Friedrich August von Hayek argues for an immediate Anglo-French federation as a practical pledge of British commitment to Europe. His case joins two problems often treated separately: the vulnerability of minorities to national economic policy, even under democratic government, and France’s reasonable fear that a Central European federation would reinforce German predominance. Drawing on Central Europe’s mixed populations, Hayek challenges the hope that better borders alone could secure peace. This brief intervention shows why he regarded voluntary limits on British and French sovereignty not as a concession to follow victory, but as a condition for a settlement others could accept on equal terms.

How much can statistical evidence tell us when the economic meaning of what it measures remains unsettled? In this short 1939 review of Solomon Fabricant’s Capital Consumption and Adjustment, Friedrich August von Hayek weighs that difficulty without dismissing the research it complicates. He questions whether business-accounting distinctions adequately capture capital used up in production and changes in its value, yet welcomes Fabricant’s evidence on depreciation, repairs, losses, and the expected useful lives of capital goods. The review offers a compact instance of Hayek’s critical judgement: doubts about aggregate measures coexist with appreciation for carefully documented detail. Its interest lies in this distinction between a study’s unresolved theoretical foundations and the concrete knowledge its statistical work can nevertheless provide.

A federation of formerly sovereign states can secure peace, this German-language essay argues, only as an economic union — yet that union disables much of the nation-state's interventionist repertoire and cannot simply hand it to a federal center. Free movement of goods, labor, and capital turns the federation into a single price area, stripping member states of tariffs, monopolies, and independent monetary policy. But protectionism cannot migrate upward either: the solidarities that sell a tariff as aid to "our" producers dissolve among peoples who share no thick common identity, and the same thinness defeats central planning, which presupposes agreement no diverse union possesses. The federation needs only a negative power — to stop states from rebuilding economic borders, not to plan in their place. Federalism, Hayek concludes, completes liberalism rather than enlarging the state.

Das Bundesgebiet wird ein einziger Markt und die Preise in seinen Teilen werden nur um den Betrag der Transportkosten differieren.

English translation: “The federal territory becomes a single market, and prices in its parts will differ only by the amount of transport costs.”

Remembered by his contemporaries as a banker, abolitionist, and Evangelical of the Clapham circle rather than as an economist, Henry Thornton is here restored by Hayek to the front rank of monetary thought. The introduction to Thornton's Paper Credit of Great Britain reads the 1802 treatise as the point where classical monetary analysis begins, born of the crises of 1793 and 1797 and the Bank Restriction. Hayek credits Thornton with distinguishing internal from external drains, anticipating both liquidity preference and Wicksell's separation of the market and natural rates of interest, and framing the doctrine of forced saving. Against the reduction of everything to over-issue, and against Ricardo's later narrowing, the case is made for a disciplined practical banker who theorized the credit system from within.

“We are all City people and connected with merchants, and nothing but merchants on every side”

Hayek’s objection to Keynes’s wartime financing proposal begins with agreement: compulsory savings could restrain civilian spending more fairly and efficiently than inflation. In this short 1939 article, republished here in 1997, the dispute turns instead on what happens when those savings become repayable. Keynes envisages releasing deposits during a postwar slump; Hayek asks whether Parliament could withstand demands for repayment when increased spending would be dangerous. The article offers a concrete encounter between economic design and political pressure, rather than a rehearsal of their wider theoretical disagreements. Hayek’s tentative alternative—converting savers’ government claims into interests in industrial capital—sharpens the central question: how can a workable wartime policy avoid creating an unstable peacetime obligation?
