Emil Lederer: Versuch einer reinen und realistisch-empirischen Theorie des Konsumentenmonopols (1912)

Lederer’s article examines whether organized consumers can lower prices below competitive levels as producer monopolies raise them above those levels. Moving from consumer surplus through abstract pricing models to the social significance of consumer associations, it identifies a fundamental asymmetry: producers can restrict output to maximize profit, whereas consumers cannot durably restrict demand without frustrating the needs their organization exists to satisfy.

The opening analysis challenges a producer-centered economics while clarifying consumer surplus. Lederer rejects its measurement through subjective valuations that would assign infinite worth to necessities. Such a calculation misrepresents ordinary economic consciousness:

Auch entspricht es nicht dem tatsächlichen Bewußtsein des wirtschaftenden Menschen, sich täglich und stündlich über seine Lebensrettung zu freuen, weil er Dinge, die er ∞ schätzt, doch für Opfer erwerben kann, die er vergleichsweise gering schätzt.

English translation: Nor does it correspond to the actual consciousness of the economizing man to rejoice daily and hourly at the saving of his life because he can after all acquire things which he values at ∞ for sacrifices which he values comparatively little.

Instead, consumer surplus is understood as the difference between the maximum monetary price a buyer would pay and the actual price. Producer monopoly seeks to absorb this difference, while consumer policy seeks to enlarge the income released by lower prices:

Und alle Konsumentenpolitik wiederum wird darauf hinauslaufen, diesen Konsumentenüberschuß möglichst zu erhöhen, die Preise so zu stellen, daß für jede Ware der Konsumentenüberschuß, also das freiwerdende Einkommen, das Maximum erreicht.

English translation: And all consumer policy in turn will amount to raising this consumers' surplus as far as possible, to setting prices in such a way that for every commodity the consumers' surplus, that is, the income thereby released, reaches its maximum.

The first pricing model assumes reproducible goods, uniform production costs, and equal consumer valuations. United demand can force sellers down to the competitive price, but cannot secure sustained supply below cost. Lederer marks the limited result built into this simplest case:

Dieser einfachste Fall ist nun so gewählt, daß gar kein niedrigerer Preis möglich ist, als derjenige, welcher sich bei der freien Konkurrenz feststellt.

English translation: This simplest case is now so chosen that no lower price at all is possible than that which establishes itself under free competition.

With differing costs and willingness to pay, the competitive price likewise reappears when the association presents its entire demand simultaneously. Lederer then considers whether consumers could appropriate the characteristic instruments of producer monopoly: price discrimination and restriction of quantities. Sequential purchases at different prices might capture producers’ differential gains, but low-cost producers can resist initial low bids when they know further demand remains unsatisfied.

Restricting purchases exposes the deeper difference between the two forms of organization. Producers can sacrifice sales to increase profit; consumers seek satisfaction, not simply the largest monetary surplus. Unmet needs therefore undermine a collective strategy of withholding demand. An association might instead charge wealthier members more and poorer members less, expanding provision through internal redistribution. Yet this requires authority and social commitments beyond the mere aggregation of purchasing power. Cooperative production offers another possibility: efficient enterprises may displace high-cost producers, but the resulting price reductions resemble competitive entry, supplemented by members’ appropriation of entrepreneurial profit.

The realistic-empirical analysis shifts attention to markets where competition is already obstructed. Consumer associations initially replace merchants, reduce trading margins, and challenge local commercial monopolies. Their achievement is thus less a reversed monopoly than a restoration of competitive conditions. Outside merchants also constrain attempts at internal price discrimination by offering members alternative sources of supply.

Lederer nevertheless refuses to reduce organization’s significance to prices. Economic power includes contractual dependency and the capacity to dominate counterparties. Consumer organization can strengthen vulnerable buyers and make them more independent participants in exchange. Cooperative production similarly matters as a means of removing barriers and extending organized control over supply.

The concluding argument connects these developments to class formation. Organization carries the employer–employee antagonism from production into circulation, giving relations between sellers and buyers a broader social character. Production planned for associated consumers can strengthen economically weaker groups, support social policy, and benefit buyers outside the association. Yet cooperative expansion does not guarantee emancipation: heavy industry and agricultural producers may retain control over essential inputs and absorb downstream savings through higher prices. Consumer organization can recover competitive conditions, but cannot reliably preserve them against entrenched upstream power. The limits of its economic leverage therefore lead Lederer toward the political and social dimensions of organized conflict.
