Higher wages can be a cost to producers—but can they also bring idle factories back into production? In this 1927 lecture, Emil Lederer examines the conditions under which wage increases enlarge purchasing power and the domestic market. His distinctive focus is on the obstacles between productive potential and actual output: displaced workers cannot instantly change occupations, and cartels may preserve prices by restricting production. Under such conditions, he argues, higher real wages can stimulate demand and compel productive reorganization. Where capacity is already fully employed, however, increased consumption may constrain investment. By refusing both automatic wage cuts and unconditional wage increases, Lederer gives readers a concrete way to distinguish a shortage of demand from a shortage of productive resources—and to see why that distinction matters for wage policy.

Can an economy become poorer while its capacity to produce grows? In this 1927 critical review of Gustaf Cassel’s memorandum for the World Economic Conference, Emil Lederer contests the claim that excessive wages and trade-union power explain European unemployment. German wage and employment figures provide a concrete test of that diagnosis; producer monopolies expose its uneven treatment of economic power. Lederer concedes that wages can obstruct necessary investment, but asks what happens when low pay and high prices leave expanding factories without sufficient buyers. His distinctive argument is conditional: higher wages may compel technical improvement and make increased productive capacity usable. The review offers a precise way to distinguish wages that hinder accumulation from wages that allow the gains of modernization to reach production and consumption.

A diagram can show how prices and quantities depend on one another without explaining the social relations they express. This distinction guides Emil Lederer’s 1927 review of Enrico Barone’s theoretical economics in its German edition. Lederer welcomes Barone’s graphical method as training in rigorous thought, yet questions what equilibrium analysis leaves unexplained. His treatment of interest makes the objection concrete: capital’s capacity to yield a surplus does not by itself explain why interest exists. Neither rejecting formal theory nor accepting its explanatory sufficiency, Lederer asks readers to recover the economic circumstances behind its constructions. This short review offers a precise account of what mathematical discipline can contribute to economic understanding—and why it needs historical and social interpretation alongside it.

Greater productive capacity does not guarantee a market for what factories can make. In this closing contribution to a 1927 conference discussion, Emil Lederer argues that rationalization can undermine its own gains when wage restraint and high prices leave capacity unused. His distinctive move is to treat rising production costs not simply as an objection to higher wages, but as a possible consequence of insufficient demand. Cartels sharpen the tension by financing expansion while restricting output; wage increases, he contends, may supply the adjustment that lower prices should have delivered. These compact replies to fellow speakers let readers follow a concrete dispute over how technical efficiency becomes—or fails to become—greater consumption, while showing why Lederer insists that theoretical disagreement needs a shared empirical basis.

Industrial capitalism, in Emil Lederer’s account, threatens the family and village solidarities that earlier conquests of China had left intact. Yet their disruption also creates new possibilities for collective action through factories, unions, student organizations, and a political party. Writing in 1927, Lederer asks what makes this upheaval more than another cycle of dynastic collapse. His distinctive emphasis falls on the social foundations of state power: how people secure livelihoods, acquire education, and organize beyond inherited obligations. The Kuomintang’s coalition of workers, intellectuals, and nationalist business interests becomes a test of whether new solidarities can sustain public authority despite sharpening class conflict. Read as a contemporary interpretation rather than a settled history, the article offers a concrete account of the connections Lederer draws between industrialization, political organization, and China’s capacity to resist foreign domination.

Compulsory protection against sickness, accident, invalidity, and old age marked, for Lederer, something historically new: neither charity nor the older law shielding workers at the bench, but the incorporation of wage earners into state-organized security. He traces its origins to Bismarck's conservative answer to socialist agitation and the Sozialistengesetz, weighs Brentano's liberal objections, and identifies compulsion as the decisive innovation that voluntary mutual aid could never supply. Comparative chapters set Britain's approved societies against Soviet Russia's employer-financed system; accident insurance, he argues, matters most where it shifts industrial risk onto the Berufsgenossenschaften. After the war, inflation and mass unemployment loosen the tie between contribution and benefit, turning insurance into public provision. Part of the Grundriss der Sozialökonomik, the chapter reads social insurance through a set of durable oppositions: insurance versus provision, compulsion versus the self-administration of the insured.

Mit Recht sieht man in der Unfallverhütung ein volkswirtschaftlich wichtigeres Ziel als in der Unfallentschädigung.

English translation: “Accident prevention is rightly regarded as an economically more important goal than accident compensation.”

Does Marx's sharp line between capitalist and proletariat still describe Weimar Germany? The answer, delivered to an organized employees' milieu, is that the basic relation holds — the mass remains separated from the means of production — but the proletariat is no longer a homogeneous body of factory hands. It is a stratified class of workers, salaried employees, civil servants, technicians, and small rentiers, deliberately divided by rank, title, and the old authoritarian state's politics of teile und herrsche. Mechanization expands output without expanding manual labor, so only by fusing workers, employees, and officials into one Arbeitnehmerschicht does the dependent population become a democratic majority. Salaried employees may not yet call themselves proletarian, Lederer argues, but they increasingly share the proletariat's fate — and emancipation requires unity without erasing internal difference.

Der gesellschaftliche Zustand ist das Werk des Menschen, er ist gestaltet, ist gestaltbar und umgestaltbar.

English translation: “The condition of society is the work of man; it is shaped, it is shapeable and reshapeable.”

A bank’s appeal to economic freedom becomes, in Emil Lederer’s hands, a test of whose freedom it protects. In this 1928 article, he examines the Darmstädter und Nationalbank’s report for 1927, contrasting its opposition to wage regulation with its acceptance of agricultural assistance and silence about protective tariffs. His critique is economic as well as political: when capital-goods industries already operate at capacity, lower wages cannot simply conjure additional machinery and materials into existence. Readers encounter a concrete challenge to the identification of business profits with productive investment, and an account of regulation that asks not whether economic power is exercised, but whether it rests with public institutions, employers, or cartels.

Every endogenous theory of crisis, this 1928 essay contends, must in the end become a theory of disproportion — not a hunt for one privileged cause but an inquiry into which mismatches harden into cyclical form. Lederer locates the decisive asymmetry in unequal elasticity: raw materials and profits rise faster than wages, salaries, and interest, so accumulation shifts the social product away from consumption even as real wages climb. Ordinary discrepancies self-correct through price and capital movements; crisis begins only when a distributive disproportion becomes rigid and resists the market's usual repair. Banks and technical innovation amplify the swing. Against those who would cure a slump by lending alone, he warns that producer credit cannot conjure the final purchasing power output needs, and that noninflationary recovery would demand a degree of coordinated planning beyond the ordinary banking system.

Eine Diskrepanz der Einkommen aber löst keine Gegenbewegung im Angebot der Arbeitskräfte aus.

English translation: “A discrepancy in incomes, however, triggers no counter-movement in the supply of labor.”

Does capitalism’s increasing organization signal its exhaustion—or merely a change in how it grows? In this conference intervention, originally published in 1929, Emil Lederer challenges Werner Sombart’s diagnosis of “late capitalism” by separating organizational change from declining dynamism. Large family-based enterprises in China and Japan unsettle a European chronology built around the individual entrepreneur: what looks like old age in one setting may accompany capitalism’s beginnings elsewhere. Yet Lederer also resists making modern technology proof of capitalism’s permanence. A socialist economy would still need cotton spindles; its distinguishing feature would be the social organization of production. This brief contribution offers a pointed way to examine claims of economic decline without confusing technical capacities, business structures, and the social relations that sustain them.

Does expanding credit cause an economic upswing, or does it accommodate growth already under way? In this brief conference intervention, Emil Lederer challenges Schlesinger’s banking-centred explanation by reconnecting monetary movements with productive capacity, technical possibilities and costs. His pointed analogy—letting out clothes does not cause their wearer to grow stouter—exposes the danger of confusing accommodation with causation. Yet credit is not merely passive: once induced by productive opportunities, it can enable further expansion. The sharpest test comes from falling costs, which, Lederer argues, can allow production to grow without additional credit. This compact exchange offers a precise distinction between a condition that enables growth and a cause that initiates it.

A stable currency need not mean an economy can bear its reparations burden. In this brief conference contribution, published in 1929, Emil Lederer shifts attention from transferring payments abroad to raising the resources at home. His concern is concrete: defending currency parity through credit restriction could undermine the economy whose capacity makes payment possible. Responding to fellow participants, he also questions reliance on foreign loans when borrowing costs rise and lenders’ confidence weakens. The contribution offers a sharp distinction between monetary success and economic viability—and explains why, for Lederer, transfer protection matters chiefly as grounds for revising the reparations plan when domestic damage becomes evident.
