Hayek reads Margaret Cole’s commemorative collection through a pointed tension: how did the Webbs’ Fabian gradualism lead to admiration for Soviet communism? In this short 1950 review, he highlights their associates’ testimony that the Soviet allegiance continued, rather than overturned, their earlier political philosophy—including a reported preference for Lenin’s abandonment of workers’ control. He also challenges the collection’s biographical balance, arguing that Beatrice’s prominence obscures Sidney’s intellectual originality and political influence. The review offers a compact encounter with Hayek as a critical reader of socialist biography: appreciative of firsthand testimony, alert to its omissions, and intent on distinguishing recollections of a partnership from an explanation of how its governing beliefs were formed.

Do British industrial employment and labor supply respond to real wages, or separately to money wages and prices? In this brief conference-paper abstract, Gerhard Tintner reports estimates for 1920–1938, distinguishing employers’ wholesale-price measure from workers’ cost of living. His demand estimates suggest that the wage–price ratio matters, but the estimated elasticity changes from −0.4 to −0.7 when a time trend is included. On supply, he is more guarded: the negative elasticities are interesting, yet dependence on wages and prices remains uncertain. The abstract offers a compact encounter with an empirical tension—how much an econometric estimate can establish when its magnitude depends on specification and the underlying relationship itself is doubtful.

Discarding a metaphysical sentence does not necessarily dispose of the problem it was meant to express. This distinction guides Felix Kaufmann’s examination of logical positivism: can linguistic analysis clarify knowledge without presupposing meanings and standards that linguistic conventions cannot supply? In this 1950 essay, Kaufmann reads the disagreements between Wittgenstein and Carnap as substantive conflicts, not merely successive refinements of one programme. Drawing on Husserl, he distinguishes propositions and their logical relations from assertions accepted provisionally in scientific inquiry. The distinction lets readers see why deductive entailment and the revisable procedures of science require different accounts—and why, for Kaufmann, positivism’s achievements in clarification leave its central questions about meaning, experience, and truth unresolved.

Why do warnings about harmful economic policies so often fail to persuade? In this review essay, republished in 1952, Ludwig von Mises finds an answer in the ideological commitments through which policy failures are interpreted. His appreciation of Benjamin M. Anderson’s posthumous Economics and The Public Welfare places a practicing bank economist’s warnings about credit expansion and intervention against what Mises regards as progressive faith in socialism’s historical inevitability. The tension is between economic diagnosis and political conviction: consequences that discredit a policy to one observer may justify further intervention to another. Readers encounter both Mises’s polemical classification of rival doctrines and his more personal account of the historian’s responsibility to warn contemporaries—a responsibility he connects with Anderson’s insistence on trust and promise-keeping in monetary affairs.

A useful textbook can still teach distinctions that obscure the processes it seeks to explain. In this 1950 review of the third edition of Elmer Clark Bratt’s Business Cycles and Forecasting, Joseph A. Schumpeter combines a strong teaching recommendation with scrutiny of statistical and conceptual habits. He questions trend fitting, the separation of short cycles from longer movements, and the neglect of individual industries in accounts of economy-wide fluctuations. His concern is causal: do the categories clarify mechanisms, or merely organize observations? Especially revealing is his distinction between factors external to a formal model and those external to business activity. This compact review shows how Schumpeter’s welcome for complementary cycle theories coexists with exacting demands on the assumptions used to classify and explain economic change.

Why should interchangeable factors guarantee determinate values? In this brief conference abstract, Oskar Morgenstern challenges that familiar economic assumption through game theory. He treats the extra value created by combining factors not as an awkward exception, but as something the characteristic function of an n-person game can describe. His sharper challenge concerns substitution: he points to games involving six players or factors in which substitutability does not permit values to be assigned. The examples are announced rather than demonstrated here, but the distinction is clear: interchangeability need not secure the determinate equilibrium economists seek. This compact statement shows why Morgenstern redirects attention toward the different, more complex game-theoretic notion of a “solution.”

A military program can demand more tanks and ships yet undermine itself by diverting steel from the railroads needed to move them. This concrete tension anchors Oskar Morgenstern’s 1950 article on economic computation: requirements cannot be assessed separately when industries compete for resources and depend on one another’s output. He argues for mathematical analysis while confronting its limits—delayed statistics, information lost through aggregation, and an economy coordinated by decentralized decisions rather than commands. An interindustry calculation traces how an order for chemicals and munitions generates still larger demands elsewhere. The reader discovers both what computation can expose beyond administrative intuition and why proving a program feasible does not establish that it is the best available choice.

Written in the aftermath of a catastrophe its author dates to 1932–1945, this closing synthesis measures humanity's ascent against its recurring descent into madness. Thurnwald traces self-domestication from foragers through plant cultivators and pastoralists to the Metal Age and the archaic state, giving Überschichtung—the superimposition of specialized groups, herders over cultivators—pride of place as the engine of caste, serfdom, and slavery. Institutions of kinship, economy, law, and religion are read through cases from Maori communal redistribution and Buin shell money to the Sumerian temple economy, while universal religions appear as reforms against aristocratic cults. The verdict is somber: technical command of external nature has far outrun any comparable command of social life, whose domestication remains grievously unfinished.

Die Menschen haben die Natur in nicht unerheblichem Ausmaß zu meistern verstanden, doch nur wenig ihr Zusammenleben.

English translation: “Human beings have managed to master nature to no small extent, but their common life only very little.”

Economics had long borrowed its self-image from mechanics, treating prices and quantities as passive magnitudes tending toward equilibrium. Against that inheritance, this programmatic essay introduces the theory of games that Morgenstern developed with John von Neumann, insisting the mathematics is essential rather than decorative. Isolated maximization may suffice for a Robinson Crusoe, or for the limiting cases of monopoly and pure competition; it fails wherever each agent's best move depends on what rivals conceal, threaten, or choose. Two-person zero-sum games yield saddle points and mixed strategies, making bluff and secrecy formal elements of rational conduct; games of three or more introduce coalitions, compensations, and solution sets rather than single equilibria — the natural language of cartels, unions, and bilateral monopoly. Rationality itself, he argues, cannot be defined before the strategic situation has been analyzed.

Jeder einzelne strebt nach seinem maximalen Vorteil, und die Interessen aller oder der meisten stehen miteinander in Widerspruch.

English translation: “Each individual strives for his maximum advantage, and the interests of all, or of most, stand in conflict with one another.”

A pension promises future income—but what makes that income secure? In this article, originally published in 1950 and reprinted in 1952, Ludwig von Mises separates the legal promise from its economic foundations. He argues that employer contributions form part of workers’ total compensation rather than a costless addition to wages, and that inflation can erode benefits long before retirement. His distinctive emphasis is on workers’ dependence on capital maintenance and investment: the resources sustaining future production matter as much as the pension contract. Connecting payroll costs with the purchasing power of payments decades away, the article offers a pointed way to examine the gap between a nominal entitlement and the goods it will eventually buy.

A coherent individual plan does not guarantee a coherent social outcome. In this encyclopaedia entry, first published in 1950 and reprinted with editorial annotations in 2022, Friedrich August von Hayek locates economics’ distinctive task in explaining how separately formed plans interact—and produce consequences nobody intended. His history of economic thought gives particular weight to marginal utility, which made individual valuations central to explanations of prices and allocation. Yet his account of spontaneous coordination also includes unemployment and wasted resources: explanation is not endorsement. Readers can discover why Hayek distinguishes the logic of a single choice from the causal analysis of social processes, and why he denies that economic science alone can establish the desirability of a policy such as free trade.

Economics is a science, a social science, and an analytical social science—Lachmann's 1950 inaugural lecture unfolds each claim in turn. As science it seeks systematic, value-free generalizations about observable phenomena, leaving judgments of the good to philosophy; as social science it studies not a special material object called man but phenomena—prices, output, employment—intelligible only as consequences of human choice under scarcity. Borrowing Robbins's ends-and-scarce-means framework, Lachmann insists economics is not psychology: it analyzes the logical implications of choices once made, not the motives behind them. Its method is compositive, tracing complex phenomena back to the plans that compose them, so that even failure becomes intelligible only by reconstructing the plans that failed. The lecture also polices history, warning against pseudo-explanations that personify 'Capitalism' or 'Industrialization,' and denying that any single invariant 'Trade Cycle' exists.
