Economic figures acquire authority because they look precise, and that appearance, Morgenstern argues, is often typographical rather than epistemic. His revised methodological study insists economics learn what the natural sciences long ago accepted: every observation carries an error, and no serious use of data can ignore its size. Ranging across foreign trade and gold-movement statistics, business accounting, national income, and growth-rate computation, he shows how paired export and import reports fail to match, how revisions never settle, and how deliberate concealment distinguishes economic data from a nature that does not lie. The demand is not for less quantification but for more honesty about it: reliability estimates, stated error ranges, and a refusal to let refined econometric operations amplify the illusion of knowledge. Data, on his account, become scientific information only when integrated with theory.

We must carefully distinguish between what we think we know and what we really do and can know.

Rebuilding a scholarly discipline after a world war is partly a matter of statutes, dues, and committee votes — and this report captures economics doing exactly that. Writing for the American Economic Association, Haberler argues for joining the newly forming International Economic Association, whose design meets the conditions Princeton had set: a modest structure resting on existing national bodies, financed but not governed by UNESCO, and cheap to support at $200 in annual dues. He recounts the April 1949 Paris meeting, the draft statutes reviewed paragraph by paragraph, and the interim slate of officers awaiting the Council's confirmation. Behind the procedural surface lies a real transition: economics reconstituting itself as an organized international profession through deliberately limited cooperation.

In accordance with the Interim Arrangements provided in the Draft Statutes, the Interim Committee nominated Professor Schumpeter as President, M. Rueff as Vice President, and Ronald Walker (Australia) as Treasurer of the I.E.A.

Capitalism may prepare the way for socialism through its organizational successes rather than its failures. In this 1950 article, Hans Bayer explores that paradox in Schumpeter’s thought: innovation becomes routine, committees replace entrepreneurial initiative, and large enterprises develop capacities for centralized coordination. Bayer reads these changes through Schumpeter’s integration of economics, history, and sociology, while distinguishing a forecast of socialist development from approval of administrative controls. British Labour planning gives the argument a concrete contemporary test. The article’s central tension is between Schumpeter’s personal opposition to socialism and his willingness to acknowledge tendencies pointing toward it. Bayer’s portrait shows how an economist’s account of institutional change can challenge both his own political preferences and the ideal of perfect competition.

Different statistical aims can lead to closely related estimating equations without making the methods interchangeable. In this mathematical article, Gerhard Tintner connects canonical correlation, principal components, weighted regression, and discriminant analysis through constrained optimization. His distinctive move is to identify the matrices and normalization conditions that give a shared algebraic structure its different statistical meanings: a covariance matrix paired with the identity in principal components, for example, becomes sample covariance paired with error covariance in weighted regression. Readers can discover how apparently separate procedures meet through reductions to common stationary equations—and why their objectives and assumptions still matter. Tintner confines the comparison to estimation, leaving sampling distributions outside the argument.

Haberler builds the theory of comparative cost from a two-country, two-commodity opportunity-cost model, then presses on the imperfections that critics invoke to justify protection. A mere catalogue of deviations from the competitive ideal, he insists, proves only possibility, not necessity: factor immobility alone leaves trade welfare-improving so long as factor prices stay flexible, and it is rigid wages—especially those maintained by unions—that generate the unemployment which can make trade inferior to autarky. Even then protection is a second-best, largely short-run remedy. He extends the same discipline to external economies, showing how unrecognised ones can make a country appear to hold a comparative advantage in the wrong commodity, and to the infant-industry argument, which he accepts in principle while noting it can equally counsel freer trade.

It can be easily shown, however, that what really causes trouble and may make trade detrimental and justify protection is rigidity of factor prices, which may or may not be associated with immobility of factors.

Defending free enterprise once meant, for many European economists, opposing patents. Fritz Machlup and Edith Penrose recover this nineteenth-century dispute to ask what can justify granting exclusive rights over knowledge others might independently discover. Their 1950 article combines the history of abolitionist campaigns—including the Netherlands’ abolition of patents in 1869—with a careful separation of claims too often treated as interchangeable: property, fair reward, incentives, and disclosure. Rewarding inventors, they show, does not by itself establish patents as the right instrument; stimulating invention does not prove that protection is necessary or worth its social costs. By distinguishing the political victory of patent advocates from the unresolved economic debate, the article gives readers concrete grounds for questioning what exclusive rights accomplish—and at whose expense.

A country’s need for imports is not the same as its demand for dollars—and foreign aid does not, by itself, prove a foreign-exchange market deficit. In this 1950 article, Fritz Machlup makes these distinctions central to his diagnosis of the postwar dollar shortage. He separates effective demand at a given exchange rate from planners’ desired imports and accountants’ records of past financing. His criticism of the IMF’s treatment of relief and reconstruction aid gives the analysis a concrete edge: assistance may pay for purchases that would never otherwise have occurred. Readers can discover why apparently similar deficits call for different responses, and why the case for productive foreign assistance must be distinguished from the case for exchange-rate adjustment.

Two rival redrawings of the φ-surface, one by J. Mars and one by H. G. Johnson, prompt this comparison, though the stakes are conceptual rather than merely graphical. Shackle defends a deliberate division of labour: the φ-surface locates the standardized focus-values of a venture, while a separate indifference-map registers the chooser's temperament toward possible gain and loss. Mars's version, by making φ algebraically summable across gains and losses, would let the surface rank ventures on its own and render that map redundant, dissolving the independent representation of an individual's attitude to uncertainty. Through profiles, translated lines, and 'crank-handle' constructions Shackle exposes the cost, and defends his 'subliminal' region, where tiny gains under extreme potential surprise command no attention. Johnson's wooden three-dimensional model he treats more warmly, as suggestive but not decisive.

By abandoning, or drastically circumscribing the role of, the gambler indifference-map, Mr Mars loses an essential ‘degree of freedom’ which my system possesses.

Workers bear the consequences of business failure—but does that give them a claim to help direct the enterprise? In this two-installment article, Hans Bayer examines American union–management cooperation as something more demanding than wage bargaining or joint efforts to raise productivity. The General Motors dispute makes financial disclosure a test of managerial openness; the disappearance of wartime committees exposes the fragility of participation granted for temporary purposes. Bayer argues that lasting cooperation requires strong unions, not their weakening. Yet he also asks whose interests cooperation serves: agreement between employers and workers may protect jobs while imposing costs on consumers. His distinctive concern is the connection between authority inside the firm and economic security beyond it, showing why workplace participation cannot substitute for institutions capable of addressing unemployment and technological displacement.

Behind the United States’ reputation for laissez-faire, Hans Bayer finds a growing apparatus of economic coordination. His 1950 article asks how dispersed federal institutions can pursue employment, production, and purchasing power without replacing decentralized economic activity with comprehensive state command. Drawing on Washington discussions and government reports, he examines the Council of Economic Advisers’ practical influence and shows how agricultural credit, public investment, and financial regulation can serve shared objectives. The distinction is between anticipating economic instability and repairing its damage after the fact. Bayer does not present coordination as complete: administrative fragmentation and business opposition remain obstacles. His account offers a concrete view of how public responsibility for economic stability can expand through existing institutions rather than through a single centralized planning authority.

Does unified income taxation threaten federalism, or does that objection leave the costs of fragmented taxation unexamined? In this 1950 reply to Theo Keller’s criticism of his Bundesstaatliche Finanzordnung, Alfred Amonn demands concrete grounds for resisting Swiss fiscal reform. His perspective is conditional rather than categorical: a debt sustainable today may constrain tomorrow’s borrowing, while a one-time levy on existing wealth may permit relief from recurring taxes. The article’s interest lies in how Amonn separates these claims from the political labels attached to them. Readers encounter a pointed dispute over what would count as evidence against reform—and where constitutional loyalties require an argument about practical consequences rather than an appeal to attachment.

Choosing a course of action is not like selecting between two objects already on a table. In this article, Alfred Schütz asks how alternatives themselves take shape during deliberation, as both the imagined projects and the person considering them change. His distinctive starting point is that we envisage an act as already accomplished, then work back towards the means of achieving it. Such anticipation depends on present knowledge that the action itself may alter. Bringing phenomenology to ordinary practical reasoning, Schütz shows how biography and interests give possibilities their weight, and how doubt becomes a decision without yielding final certainty. The analysis gives readers a precise way to question social-scientific models that treat actors’ alternatives as fixed and their motives as fully transparent.
