Oskar Engländer, Zur Theorie des Produktivkapitalzinses (1908)

Engländer’s monograph intervenes in the marginalist capital-interest debate by asking how income from produced means of production can arise without making capital a mysterious independent source of value, and without reducing all profit to rent, loan interest, monopoly, or exploitation.

Im folgenden soll der Versuch gemacht werden, die Frage der Entstehung des Produktivkapitalzinses einer Erörterung zu unterziehen.

English translation: In what follows, an attempt shall be made to subject the question of the origin of interest on productive capital to a thorough examination.

The inquiry begins with the economic use of a productive instrument: a net, oven, machine, or other means of production matters because it improves the actor’s situation compared with available alternatives. If the same person makes and uses the instrument, no distributive puzzle appears; the gain belongs to the economy that incurred the effort. The real problem begins when the maker of the productive means and its user are separate persons.

Here Engländer’s subjective-value premise is decisive. Exchange is not grounded in equality of value, objective or subjective. It occurs because each party expects an advantage, and this divergence of valuations makes a surplus divisible between different economic subjects.

Denn, um es nochmals zu betonen, jeder Tausch muß für den Tauschenden von Vorteil sein, seine wirtschaftliche Lage muß hierdurch nach seiner Ansicht gebessert werden, weil er sonst den Tausch mangels eines Motives nicht eingehen würde.

English translation: For, to emphasize it once more, every exchange must be advantageous to the one exchanging; his economic situation must, in his view, be improved thereby, because otherwise, lacking a motive, he would not enter into the exchange.

The price of a capital good is therefore not simply the capitalized value of its future product. The producer may value the machine by sacrifice, cost, or sale alternatives; the buyer values it by the expected productive result. Productive-capital interest arises through this relation of production, valuation, exchange, and bargaining over the advantage made possible by the instrument’s use.

Die objektive Wertgleichheit besteht nicht, weil es einen objektiven Wert, der von den einzelnen Wirtschaftssubjekten unabhängig wäre, nicht gibt. Die subjektive Wertgleichheit aber kann beim Tausche nicht bestehen, weil sonst mangels eines Motivs der Tausch überhaupt nicht zustande gekommen wäre.

English translation: Objective equality of value does not exist, because there is no objective value independent of the individual economic subjects. But subjective equality of value cannot exist in exchange either, for otherwise, lacking any motive, the exchange would not have come about at all.

Engländer’s target is any theory that identifies the value of higher-order goods too directly with the value of the consumer goods they help produce. He accepts subjective value, but insists that it must be applied to distinct persons, not to an imagined unified valuing subject. The producer of the means of production and the entrepreneur who applies it occupy different economic positions.

This leads to his rejection of exact positive imputation. In capitalist production, the owner or entrepreneur purchases instruments, hires labour, advances costs, bears risks, and receives any residual after replacement and outlays. But economic theory cannot divide the joint product into exact causal shares attributable to labour, capital, land, and entrepreneurship.

Eine aufteilende Zurechnung besteht nicht und die Wirtschaft bedarf ihrer nicht.

English translation: A distributive imputation does not exist, and the economy has no need of it.

Only a negative or counterfactual attribution is possible: one may ask what would be lost if a factor were absent. This weakens both apologetic and socialist simplifications. Capital does not earn interest because it has a separately measurable product of its own; but theory alone also does not prove that the whole residual belongs to labour. The surplus is a result of jointly necessary conditions organized under private property, exchange, and divided production.

Engländer also criticizes the doctrine that competition and reproducible costs must eliminate profit. Competition may reduce, redistribute, or equalize gains, but it cannot remove gain as a motive for production. If no surplus is expected, production is not undertaken.

Eine auf Ausschließung des Gewinnes gerichtete Tendenz hat das Kostengesetz nicht nachgewiesen.

English translation: The law of costs has not been shown to possess any tendency directed toward the exclusion of profit.

The book’s significance lies in its internal critique of Austrian capital theory. Engländer preserves subjective value and marginal reasoning, yet turns them against theories that treat interest as a necessary agio, a separable capital product, or an exactly imputed share. Productive-capital interest is instead the distributive expression of productive advantage under exchange, private control of means of production, and divergent valuations. Its existence can be economically explained; its justice is not thereby settled.
