Idle factories seem to make an obvious case for encouraging consumers to spend. In this 1931 article, Friedrich August von Hayek challenges that inference by asking what machinery needs besides customers to sustain production. His answer directs attention to intermediate goods and the resources committed between the beginning of a process and its finished output. A messenger analogy makes the point concrete: longer journeys require more messengers in transit to maintain regular arrivals. Hayek argues that saving supports this temporal organization, while increased consumption can deprive specialized production processes of the resources they require. The article offers a compact theoretical challenge to spending-led recovery, showing why, in Hayek’s account, visible spare capacity is not the same thing as an abundance of usable capital.

Weimar's debate over Rationalisierung becomes, in this 1931 study, a theory of capitalist dynamics. Against the compensation doctrine that markets quietly reabsorb workers displaced by machinery, Lederer argues that labor-saving innovation can leave durable structural unemployment whenever its tempo outruns capital formation and the growth of jobs. His engine is the organic composition of production: modern progress means more capital and fewer workers per unit of output. A model of dynamic equilibrium disturbed by innovation in coal mining shows the mechanism — the rationalized mines draw capital from static sectors, produce the same coal with roughly half the labor, and shrink the economy's capacity to place workers, so the wage bill falls further than the social product. Neither anti-machine reaction nor laissez-faire optimism will do; what he urges is social control over the pace and direction of technical change.

Bei einem sehr schnellen Tempo des technischen Fortschritts können dann die Freisetzungswirkungen zu einer strukturellen, d. h. die Depressionsperiode überdauernden Arbeitslosigkeit führen.

English translation: “At a very rapid pace of technical progress, the effects of labor displacement can then lead to structural unemployment—that is, unemployment that outlasts the depression period.”

Delivered to the Royal Institute of International Affairs as the slump deepened, this 1931 address refuses the comfort of ideology: the Depression, Somary insists, spared neither capitalist, syndicalised, nor socialised economies alike. He traces the collapse to gold hoarding and a failing gold-exchange standard, to raw-material prices that cratered while finished goods and wages held firm, and to speculation fed by New York's call-money market. Communism, he argues, is the lesser danger; war is the greater, as distress feeds radical nationalism and the Hitler movement. His remedies—wage reductions, the breaking of cartels, state purchases of cheap raw materials, and a Franco-German confidence rebuilt under British leadership—frame his closing warning that the years ahead may earn the historian's name 'Between Two Wars.'

Europe has no lack of capital; what she needs is confidence.

The League of Nations could convene governments, administer mandates, and cultivate habits of consultation—but could it secure peace while states retained ultimate authority? In these lectures of 1931, William E. Rappard brings his experience of League service and training as an economic historian to the gap between constitutional promises and institutional practice. His revealing paradox is that growing governmental interest in Geneva could diminish the independence on which international judgment depended. Health cooperation and mandate supervision show what shared administration could accomplish; disarmament and sanctions expose what governments withheld. For Rappard, however, stronger enforcement alone was insufficient: collective security also needed procedures for peacefully correcting unjust settlements. The book makes concrete the distinction between an organization that facilitates cooperation and one capable of guaranteeing peace.

Why did a recurrent economic downturn become a world depression? Writing in March 1931, Schumpeter separates the adjustments generated by productive innovation from the pressures that made this contraction exceptionally severe. His distinctive claim is that prosperity itself transforms production in ways that require recession; external shocks cannot alone explain the reversal. Yet overlapping cycles do not account for the catastrophe. Monetary restoration, reparations, agricultural distress and price rigidities enter his diagnosis as aggravating forces, not interchangeable root causes. This short article offers a pointed way to distinguish the origins of a crisis from its amplification—and to understand why, in Schumpeter’s view, cheaper credit may fail to revive borrowing even when high interest rates can readily restrain a boom.

It is easier to dampen prosperity by a high rate of interest than to alleviate depression by a low one.

Why should an economy’s growing productive power bring bankruptcies and unemployment rather than uninterrupted prosperity? In this 1931 article, based on his Tokyo lecture, Joseph A. Schumpeter locates the answer in the boom itself. Pioneering innovations attract imitators; bank-created credit finances a rush of new enterprises before their goods reach the market. When those goods arrive, they displace older producers, while repayment of loans contracts purchasing power. Depression, in his account, is the painful adjustment to changes initiated during prosperity, not simply a monetary malfunction. The article offers a compact route into Schumpeter’s distinctive connection between entrepreneurial achievement and economic instability, while distinguishing the mechanism he seeks to explain from external shocks and statistical patterns that cannot, by themselves, establish causes.

Money makes complex production calculable, but it does not measure what people value. This distinction anchors Ludwig von Mises’s 1931 essay on subjective value theory. He extends economic reasoning beyond commerce to any conscious choice between alternatives, while reserving a narrower role for monetary accounting. Choosing honor over possessions is no less intelligible than seeking profit; neither choice requires the economist to endorse its ends. Yet, Mises argues, coordinating extended production requires prices for productive resources—a requirement that underlies his objection to comprehensive socialism. The essay offers a precise way to distinguish preference, price, and cost: valuations rank alternatives, prices enable calculation, and costs point to satisfactions forgone. It also shows why indispensable market accounts cannot become measurements of human welfare.

Die Geldrechnung ist eben nicht Wertrechnung und schon gar nicht Wertmessung.

English translation: “Monetary calculation is precisely not value calculation, and certainly not value measurement.”

Interest rates, in a normal depression, fall and prepare the recovery; in the crisis after September 1929 they fell fast and then rose again, leaving the world economy stranded short of any natural upturn. From this paradox Strigl works toward an uncompromising verdict on the demands of the day — cheaper money and a halt to falling prices, urged by Keynes in England and defended by Cassel against the specter of gold scarcity. Both amount to the same thing, and both are inflation: new money never enters evenly, but favors particular sectors first, distorting relative prices and calling forth production that no real supply of goods can sustain. Such stimulus destroys capital by misdirecting it, and any monetary attempt to obstruct the crisis's necessary liquidation is, for him, already inflation before the currency visibly collapses.

Billiges Geld bedeutet mehr Geld, bedeutet höhere Preise.

English translation: “Cheap money means more money, means higher prices.”

Calculus can locate a monopolist’s maximum profit—but who establishes the demand and cost functions on which the calculation depends? In this 1931 article, Felix Kaufmann uses that distinction to reconsider what mathematics contributes to economics. His perspective joins the logical analysis of mathematical proof to an insistence on understanding economic motives: neither formal deduction nor price curves alone supply an empirical theory of action. Against both blanket objections to mathematization and overconfident analogies with physics, he asks when simplifying assumptions make inquiry productive and when they merely make calculation possible. Readers gain a precise way to distinguish computational success from economic discovery, and to examine what assumptions about continuity, measurement, and choice permit a model to explain.

Full shop-windows and idle furnaces at the same moment: the Depression, this 1931 lecture argues, is a crisis of abundance without purchasing power, not a shortage of goods, gold, or effort. Lederer catalogues its causes — cyclical overinvestment financed by credit outrunning real saving, world markets glutted by mechanized grain, rubber, coal, and copper, a swollen German labor supply after conscription's end, and labor-saving rationalization that no longer absorbs workers as the railways once did — then diagnoses why the usual liquidation fails. Cartels and trusts fix prices and quantities, dump losses onto competitive sectors, and block the price falls that would reallocate capital; wage-cutting proves largely a dead end. His verdict is that capitalist automatism has failed, leaving a fixed economy without a plan that only conscious social direction and economic self-government can set right.

Die kapitalistische Wirtschaft ist reich an kostspieligen Paradoxien.

English translation: “The capitalist economy is rich in costly paradoxes.”

That mass unemployment is proof of excessive wages, and that cutting wages will clear the labor market, was the reigning Depression orthodoxy Lederer set out to demolish in this 1931 lecture. He grants that a ruthless wage fall might absorb idle workers for a moment, then shows why the concession dissolves: shrinking consumption, technical unemployment that no compensation doctrine repairs, the combine harvester displacing labor faster than cheaper grain can reabsorb it. Against Cassel and Clark he insists the labor market cannot be read in isolation. In the German winter of 1930/31, with cartels holding prices rigid and plants idled by quota, wage cuts could only deepen deflation while strengthening the National Socialists whose rise frightened capital abroad. Unemployment, he concludes, is structural and institutional, not a mere error in the price of labor.

Eine Lohnsenkung vermehrt aber noch nicht den Absatz, sondern verschiebt nur die Kaufkraft vom Arbeiter auf den Unternehmer.

English translation: “A wage reduction, however, does not yet increase sales; it merely shifts purchasing power from the worker to the entrepreneur.”

Abundant productive capacity and mass unemployment form the central paradox of Karl Pribram’s lecture contribution, first published in 1931 and supplied here in its 1932 republication. Pribram locates the Depression’s severity in interacting pressures: lost export markets, collapsing commodity prices, fragile credit, and production costs that resist adjustment. His distinctive concern is who bears that adjustment. Cartels can protect their prices by shifting losses downstream; wages sustain consumption even as employers treat them as costs. Comparing Germany’s financial vulnerability with Britain’s export difficulties and France’s relative insulation, he shows why apparently similar unemployment figures demand different explanations. His assessment of public works and insurance offers a concrete way to examine the tension between restoring profitable production and protecting people whose willingness to work cannot secure employment.
