What can an estimated demand curve tell policymakers—and what can it never decide for them? In this 1949 article, Gerhard Tintner connects the methodological claims of econometrics to the difficulties of measuring American agricultural demand and supply. Prices and quantities do not identify those relationships unaided: economic assumptions must first make them distinguishable. His empirical results sharpen the point. Demand estimates yield interpretable elasticities, while insignificant supply coefficients expose missing influences, including weather and possibly lagged prices. Tintner treats such failures as grounds for revising models, not concealing uncertainty. The article offers a concrete account of how theory becomes a testable numerical claim, while keeping estimates of policy consequences distinct from judgements about which social objectives deserve priority.

When does an emergency exception become permanent protection? In this 1949 article, Josef Herbert Fürth tests the Havana Charter’s escape clauses against the economic problems they were meant to address: depleted monetary reserves, industrial disruption, and trade distorted by inconvertible currencies. He accepts a bounded role for intervention while asking whether domestic policies can perpetuate the very imbalances invoked to justify restrictions. His distinctive approach separates economically defensible exceptions from politically unavoidable concessions, and legal permission from practical restraint. Readers can discover why nondiscrimination does not always prevent avoidable trade losses, why monetary policy matters to trade liberalization, and why Fürth places greater weight on international economic scrutiny than on legal rules alone.

The misery of English factory hands, the gluts of 1818 and 1826, and the depopulation of the countryside posed a puzzle Sismondi could not leave to sentiment: why did the liberal market and its machinery breed crises, unemployment, and want? This second volume presents his 1819 Nouveaux Principes as a dynamic and welfare economics set against the static equilibrium of his earlier work—and against Say's law and Ricardo, who conflated income with capital and imagined consumption almost limitless. Amonn follows Sismondi's demand that production stay proportioned to income and effective demand, his critique of Ricardian rent, his defense of small proprietorship, and his call to bind employers to their workers in sickness, age, and unemployment. Throughout, the editor marks the circular-flow insight as Sismondi's real advance while faulting the confusions that blur it.

Die statische Theorie oder Gleichgewichtstheorie stimmt nicht für die tatsächliche Entwicklung der Wirtschaft.

English translation: “The static theory, or equilibrium theory, does not accord with the actual development of the economy.”

Sealed bids for cement and steel that match to the penny are no accident but the signature of a pricing formula — and this 1949 study, rushed out after the Supreme Court's Cement Institute decision, anatomizes how that formula works and why it should go. Under basing-point pricing a delivered price is reckoned from a designated base point whether or not the goods ship from there, so 'phantom freight' and 'freight absorption' erase local cost advantages and make rival quotations converge. Machlup treats this as geographic price discrimination and, tracing case histories in steel, cement, and corn products, as a cartel embedded in freight books and classifications rather than open conspiracy. Against warnings of chaos he sets uniform f.o.b. mill pricing, under which distance again becomes visible and buyers can hunt for genuinely cheaper sources.

Almost all economic change leaves some people worse off.

What survives of the Communist Manifesto once it is read strictly as science, stripped of centenary celebration and debunking alike? Schumpeter answers by treating the 1848 pamphlet as economic sociology, separating that interpretive achievement from its thin technical economics. He ranks Marx's economic interpretation of history beside Darwin's in originality, credits him with hauling the theory of the state down from metaphysics into realistic analysis, and salutes the Manifesto's unrivalled panegyric to bourgeois enterprise as a 'constant revolutionizing of production.' Yet he dismantles the predicted polarization into two classes, the overlooked new middle class, and the doctrine of the withering state. What remains is an ideological document read as analysis, the prelude, Schumpeter says, to the whole of Marx's later work.

it is but steam that rises from the galloping horse.

Passed with little economic scrutiny, Britain's Town and Country Planning Act of 1947 becomes, in Hayek's hands, a small statutory device that reveals a large institutional danger. The development charge administered by the Central Land Board, he argues, is no modest betterment levy: fixed by policy at 100 percent of the gain from permission to change land use, it confiscates the whole expected benefit of industrial adaptation and turns land-use control into a monopoly over development itself. Because the charge falls due before any venture succeeds, the entrepreneur bears the full downside of uncertainty while surrendering the upside in advance. Suspending the price mechanism for non-agricultural land, the Act leaves in its place only arbitrary administrative discretion, and, extending the critique through a review of Charles Haar's study, Hayek concludes that the only rational charge would be none at all.

A grosser form of penalizing risk can hardly be imagined.

Military urgency does not settle how scarce resources should be allocated—or how much immediate armament a country should undertake. In this 1949 discussion contribution, Fritz Machlup challenges fellow economists to specify when market prices become less tolerable than administrative controls. Taxation can reduce civilian spending, he argues, without releasing the particular metals defense production requires; higher relative prices may still be necessary. His distinction between guaranteed defense deliveries and preferential prices offers a concrete alternative to comprehensive allocation. The argument then turns to preparedness itself: stockpiling rapidly obsolete equipment may sacrifice the productive capacity needed for a later war. Readers encounter an economist testing security proposals through their overlooked alternatives, rather than accepting either military expenditure or controls as necessities beyond comparison.

It was among writers, teachers, and journalists, not voters, that socialism first became respectable, and that, Hayek contends, is where its power always lay. He defines the intellectual not honorifically but sociologically: a secondhand dealer in ideas, a mediator who decides which doctrines come to seem modern, humane, or scientific before they ever reach the public. Their convictions form the sieve through which every new conception must pass. This is why proprietors and party managers cannot manufacture opinion to order, and why socialism, offering a bold future-oriented vision, drew able minds that a defensive, technical liberalism repelled. Drawing on Lord Acton and the line from Adam Smith, his remedy is not caution but a liberal Utopia: a case for freedom made radical, going to first principles, and intellectually adventurous once more.

The typical intellectual need be neither; he need not possess special knowledge of anything in particular, nor need he even be particularly intelligent, to perform his role as intermediary in the spreading of ideas.

Does ethical neutrality require political science to exclude moral judgments—or to make their standards explicit? Felix Kaufmann argues for the latter by drawing a precise analogy: ethical criticism judges valuations against moral standards, just as scientific criticism judges assertions against rules of inquiry. Neither set of standards possesses an ultimate rational justification, yet this need not make judgments within them merely subjective. His example of adultery’s status under a particular penal code shows why dependence on a framework differs from arbitrariness. Challenging Max Weber, Kaufmann gives political inquiry a task beyond abstaining from judgment: reconstructing the value hierarchies behind disagreement. Readers can discover how opponents may share commitments to freedom, order, or human dignity while differing sharply over their rank.

Currency depreciation can increase exports and reduce imports yet still worsen the balance of payments. In this 1949 article, Gottfried Haberler explains why physical trade responses do not settle the monetary question: prices, supply elasticities, and the currency in which the balance is measured also matter. His distinctive approach traces foreign-exchange demand and supply back through trade schedules to domestic production and consumption, showing how stable commodity markets can coexist with an unstable currency market. Readers can discover both the limits of familiar elasticity rules and the difference between an adjustment that works in principle and one that requires impractically large exchange-rate movements. Haberler also separates weak trade responses from inflationary expenditure shifts that can undo depreciation’s initial gains.

Before asking how interest-rates are determined, Shackle insists on a prior matter — what interest actually is, and what realities it manifests. His answer breaks with time-preference theory, which presumes agents already know their future, and pushes Keynes's liquidity-preference further by refusing to tame the unknown with probability. Wealth, held for 'possessor-satisfaction' as much as future consumption, may take the form of banknotes, bonds, or equipment; a man who trades banknotes for a bond swaps a known for an unknown quantity of money, and pure interest is the premium for surrendering that certainty. From gain- and loss-epitomes and uncertainty indifference curves the argument builds toward an aggregate model in which saving equals investment by identity, and finally to the British cheap-money drive of 1945–47, where reversing gilt-edged prices betray interest as a manifestation of uncertainty rather than credit standing or thrift.

The rate of interest is, of all prices, the one most inseparably bound up by the logic of its very nature with expectation and uncertainty.

A firm cannot choose its best course without considering what its rivals may do; a union bargains with an employer whose intentions it cannot fully know. In this 1949 Scientific American article, Oskar Morgenstern presents such interdependence as a mathematical problem that isolated individual maximization cannot capture. His account makes the apparent paradox of rational randomization concrete: unpredictability can protect a player from an opponent. Coalitions introduce a different difficulty, since cooperation creates gains without uniquely determining their distribution. Moving between strategic examples and economic disputes, Morgenstern shows why a solution need not be a single best outcome—and why formal privileges may depend on the bargaining arrangements that sustain them. His ambitions for game theory remain checked by the difficulty of calculating even simplified games.
