Richard von Strigl, Ertrag (1926)

Richard von Strigl’s encyclopedia article examines Ertrag—the yield or return of production—by moving from the goods obtained through production to the narrower questions of sustainable consumption and the attribution of returns to productive factors. Its central distinction is between gross output and net return: what production delivers is not necessarily what an economy can consume without impairing its future productive capacity. Strigl then connects this distinction to capital interest and economic imputation. Throughout, he separates physical production from economic valuation: a factor’s material participation in production does not by itself establish an economically attributable return.

The opening defines gross yield as the entire quantity of goods made available to the producer by successful production. Economic calculation, however, must look beyond the completed productive process. If production is to continue under conditions no less favorable than before, an equivalent initial stock of productive goods must remain available. A self-sufficient economy secures this stock by devoting part of its productive activity to replacing means of production; an exchange economy also permits individual producers to obtain replacements by exchanging part of their gross output. These are different arrangements for meeting the same requirement:

Mit der Notwendigkeit der Reproduktion des Anfangsfondes an Produktionsgütern für die Sicherung des Ertrages in der Zukunft ist die Frage nach dem Reinertrage der Produktion gegeben.

English translation: The necessity of reproducing the initial fund of productive goods in order to secure future yield gives rise to the question of the net return of production.

Net return is therefore the yield obtainable after preserving the stock of means of production undiminished. This definition supplies Strigl with a compact distinction between stationary, contracting, and expanding economies. Consuming exactly the net return maintains a static economy; consuming more reduces the resources supporting future production; consuming less and investing the remainder enlarges the productive stock and permits the expectation of greater future yield. Net return is thus not simply a remainder in an account: it marks the boundary between consumption compatible with maintaining production and consumption that draws down its material basis.

Strigl next asks when gross yield can count entirely as net return. This is possible where productive services flow continuously without expenditure necessary to maintain them. He applies this qualification to land insofar as its services do not depend on capital improvements, and ordinarily to human labor. His treatment of labor makes the economic classification depend explicitly on the worker’s social position:

Wo der Arbeiter frei ist und als Mensch gewertet wird, dort wird die Verwendung seines Lohnes seine persönliche Angelegenheit sein, wenn sie auch zur „Wiedererzeugung“ seiner Arbeitskraft führt, so wird doch der Konsum nicht als Reproduktion der Arbeitskraft aufgefaßt werden können.

English translation: Where the worker is free and is valued as a human being, the use of his wage is his personal affair; even if it leads to the “reproduction” of his labor power, consumption nevertheless cannot be understood as reproduction of labor power.

The contrast is slavery. From the slaveholder’s standpoint, expenditure on maintaining and replacing enslaved workers can be deducted from gross proceeds as the cost of preserving a capital stock. Strigl’s conceptual distinction concerns the place of consumption within the economic process: the free worker’s consumption is an end, whereas the slaveholder treats the worker’s maintenance as an intermediate productive expense. Physiological renewal alone therefore does not determine the economic category.

Produced means of production raise the replacement question directly. This leads to Strigl’s sharply delimited observation about capital-interest theory: identifying a return associated with capital does not yet explain interest, because interest must be demonstrated as a net return. The article states this requirement without attempting a full theory of interest. It then broadens the problem to production involving several different inputs. Calculation must establish both the expenditure needed to preserve each input’s future services and the share of net return attributable to each factor. Only such attribution enables an assessment of the economic efficiency of production.

Bei dieser Ertragszurechnung kann es sich auf keinen Fall darum handeln, den physischen Anteil eines jeden Produktionsmittels am Ertrage zu bestimmen.

English translation: In this imputation of yield, it can under no circumstances be a matter of determining each means of production’s physical share in the yield.

The decisive example is land. Where land of the best quality exists abundantly, it receives no economically imputed return, despite its physical contribution to production. What appears materially to be its yield may count economically as a return to labor or as a freely available gift of nature. If population growth or another change makes the same land scarce, a net return must be attributed to it even though the physical productive process remains unchanged. Economic imputation consequently follows changes in scarcity, not merely changes in technique or material causation.

Daraus ist zu ersehen, daß die ökonomische Kalkulation des Ertrages durchaus im Rahmen der wirtschaftlichen Wertschätzung vor sich geht.

English translation: From this it can be seen that the economic calculation of yield takes place entirely within the framework of economic valuation.

The concluding argument brings output and inputs under the same principle: goods acquire economic significance through scarcity relative to requirements, and productive factors receive attributable returns because their limited availability requires economizing. The article’s relevance lies in joining two distinctions often blurred together: gross versus sustainable net yield, and physical contribution versus economically imputed return. Its closing literature points toward the connected debates on imputation, capital interest, and diminishing returns, while the entry itself supplies a concise conceptual framework for understanding their relationship.
