Why does construction sometimes continue when rental returns no longer justify building? In this 1940 article, Karl Pribram connects urban ground rent to the institutions that finance development. Location alone, he argues, cannot explain the returns commanded by urban land: changing construction costs, rentals, and interest rates can generate rent even on sites without special advantages. His comparison of European and American building cycles turns on whether these returns actually govern investment. Elastic mortgage credit and expectations of appreciation can sustain construction after yields deteriorate, leaving oversupply and foreclosed properties to obstruct recovery. The article offers a precise way to distinguish rising property values from rising land rent—and to examine why measures that facilitate housing finance may also weaken restraints on speculative building.

An introductory textbook can make economics intelligible without pretending that its problems are settled. In this 1939 review of Frederic Benham’s Economics, Oskar Morgenstern makes that distinction central to his praise. He values Benham’s clear explanation of indifference curves and synthesis of production theory, but especially his willingness to acknowledge where economic analysis falls short. Morgenstern would push this candor further: exposing weak spots can awaken curiosity rather than undermine instruction. His reservations about income theory, risk, and profit sharpen a compact account of what beginners need—breadth, proportion, and reasons to question apparent certainty rather than specialize prematurely.

One of the principal aims of teaching theory should be to avoid barren specialization at too early a stage.

Does listening at home free people from the pressures of a political crowd—or bring propaganda directly to their firesides? In this review of César Saerchinger’s Hello America!—Radio Adventures in Europe, Emil Lederer tests the broadcaster’s claim that the microphone weakens demagogues by stripping away theatrical gestures and exposing insincerity. Father Coughlin and dictatorships’ multilingual short-wave broadcasts supply his counterexamples: manipulation can travel through a seemingly objective argument as readily as through a rant. Lederer values Saerchinger’s insider observations of broadcasting machinery and political figures, while asking what their reach means for public opinion. This brief review captures a precise tension between radio’s promise of independent listening and its capacity to make private homes part of an international political struggle.

Does bank credit drive economic change, or can it merely accommodate movements in trade? In this short review of Valentin F. Wagner’s history of credit theories, Fritz Machlup singles out a selective rehabilitation of the Banking School: Wagner challenges its equation of bank notes with deposits while recovering its view that bank credit may substitute for trade credit without exerting an independent dynamic influence. Machlup’s sympathy for this reconsideration does not blunt his criticism of Wagner’s elaborate classifications, repetitions, and difficult terminology. The review offers a concise encounter with a disputed distinction in monetary theory—and with Machlup’s judgement of where historical scholarship can unsettle accepted doctrine without conclusively overturning it.

Why might urban land rise in value even without any special advantage of location? In this 1939 conference abstract on Europe, Karl Pribram shifts attention from privileged sites to the changing relation between rentals, construction costs, and interest rates. His account of building activity free from governmental interference turns on an asymmetry: rentals could retain their gains through depression while construction costs fell, enlarging the residual return attributed to land. Once capitalized in property prices, that return became a cost for subsequent purchasers. This compact argument offers a precise connection between business fluctuations and land valuation—and explains why Pribram considered “absolute” ground rent potentially more influential for European building activity than the more visible advantages of location.

Why can construction continue as ground rents fall, yet fail to revive when rental returns improve? In this 1939 conference abstract on the United States, Karl Pribram locates a possible answer in mortgage finance. Comparing American building cycles with European experience, he argues that expansive credit can sustain a boom despite declining ground rent, while foreclosed properties held by financial institutions can obstruct recovery long after rental conditions become favorable. His hypothesis challenges the view that American construction cycles arise from forces separate from general business fluctuations. This compact account offers a precise distinction: the forces initiating a cycle may be shared, while mortgage-market institutions alter its duration and amplitude—and weaken ground rent’s power to regulate new building.

Symmetry makes a many-variable probability problem unusually compact in Gerhard Tintner’s 1939 article. He studies a quadratic form in independent standard normal variables with one common coefficient for squared terms and another for cross-products. Its characteristic function separates into just two factors: one for collective movement and one for the remaining contrasts. The interest lies both in this reduction and in Tintner’s effort to turn it into a usable calculation, moving from Fourier inversion and a hypergeometric expression toward tabulated chi-square densities. Readers can trace how coefficient structure determines distributional structure, while distinguishing the robust characteristic-function result from printed density formulas whose signs, normalization, and conditions require verification before numerical use.

Peace among formerly sovereign states, this 1939 essay argues, cannot rest on political or military union alone; it requires a genuine common market, and that market quietly disarms the interventionist state. Once goods, people, and capital move freely across internal borders, no member government can prop up local prices, shelter a monopoly, or sustain a restriction scheme dependent on territorial control—and, Hayek adds, the federation itself cannot easily replace those powers, because a large heterogeneous people will not agree on whose industries deserve protection. Economic planning presupposes a shared scale of values that diversity denies. Socialism becomes the limiting case: incompatible with free movement within, and lacking the common purpose a socialist union would require. Federation thus emerges as both a peace project and a liberal constraint, with Robbins and Streit in view.

The whole armory of marketing boards and other forms of monopolistic organizations of individual industries will cease to be at the disposal of state governments.

Cheap borrowing does not make steel, machinery or time more abundant. In this 1939 article, republished in 1997, Hayek asks whether wartime authorities should hold interest rates down when urgent production needs make capital scarcer. His distinctive emphasis is on investment’s timing: a machine that saves more labour overall may still be a poorer choice if its benefits arrive too late. He treats interest chiefly as a means of allocating capital, rather than rewarding saving, and follows that distinction into practical decisions about replacing worn equipment or diverting maintenance resources to armaments. The article offers a compact way to distinguish financial ease from real productive capacity—and explains why, in Hayek’s view, a misleading interest rate can distort the choices of government planners and private entrepreneurs alike.

Protecting a producer’s price can unsettle everything around it. In this 1939 address, Oskar Morgenstern examines European public monopolies through the incentives their guarantees create, rather than their formal administrative structure. Austria’s milk regulation and Czechoslovakia’s grain monopoly supply concrete cases: protected prices encourage output while consumption falls, leaving authorities to finance surpluses, restrict production, and police unofficial trade. His central contention is that each attempt to preserve the original price commitment demands further controls. Political interests in distribution help explain why retreat proves difficult. The address offers a sharply critical account of the difference between stabilizing prices and stabilizing economic life, tracing how measures intended to protect producers can shift costs onto consumers, employment, and unprotected sectors.

Split cleanly in two, the Keynesian multiplier here becomes an instantaneous logical ratio implied by the marginal propensity to consume and a dynamic process by which output actually adjusts over time. The first follows at once from how income-receivers divide any increment between spending and accumulation; but that behaviour alone, Shackle stresses, cannot explain why firms would expand the output of consumption goods. Only assumptions about entrepreneurs' reactions to sales, inventories, and expected income turn the ratio into a theory of production. Where earlier writers assumed intended accumulation and realized saving simply coincide, he foregrounds their possible divergence: an attempt to raise the pace of accumulation runs down consumer-goods stocks unless output follows. The open-economy extension folds an export surplus into the same field as domestic investment, so a rising surplus can set expansion going exactly as investment does.

Hitherto in expressing the multiplier principle authors have assumed *equality*.

Can an account of conflicting worldviews also explain why political restraint fails? In this brief 1939 review of Harley Farnsworth MacNair’s The Real Conflict between China and Japan, Emil Lederer welcomes an explanation that reaches beyond territory, wealth and power to the historical beliefs shaping state ambitions. His sharper intervention concerns the consequences of that explanation: he argues that a Japanese political system driven by prestige and unlimited ambition leaves advocates of a “sensible” policy powerless and makes appeasement futile. The review offers a compact encounter between appreciation and criticism, showing how Lederer turns MacNair’s account of ideological conflict into a question about whether a political system can accommodate moderation.
