A Note on the Development of the Doctrine of "Forced Saving"

Hayek’s note is a historiographical recovery of a doctrine he thinks had been repeatedly discovered under different labels. It reconstructs a mechanism by which new paper money or bank credit, entering through borrowers or producers, temporarily changes who can command the existing flow of goods. This coerces saving by others: rising prices and lagging money incomes reduce consumption, while entrepreneurs obtain materials and labor for additional investment. The claim is doctrinal continuity, not simple priority.

Hayek begins with Bentham, whose neglected manuscripts provide the most explicit early statement. Bentham frames the matter as an effect of “forced frugality,” in which monetary issue works like an indirect tax and shifts resources from consumers to accumulators. His starting point is the real-resource premise:

Bentham then proceeds to study, as example 2 of his “broad measures” among the non-agenda, the effects of increasing money in some detail. “Labour,” he begins, “and not money, is the real source of wealth.”

From this premise, Hayek distinguishes two questions often confused in monetary controversy: whether nominal incomes rise, and whether real capital is enlarged. If labor and instruments are already employed, multiplying money cannot by itself add to real wealth; it can only alter distribution and timing. Bentham’s formulation lets Hayek present forced saving as both possible and ethically ambiguous, since the addition to capital is purchased by a loss to those whose command over goods has been diluted.

He whose pecuniary income of 1837 is double what it is in 1801, will in point of wealth be neither a gainer nor a loser by the change.

The subsequent writers in Hayek’s sequence modify this core insight. Thornton links excessive paper issue with a temporary rise in stock through reduced consumption; Malthus and Dugald Stewart bring the idea into bullionist discussions, with Stewart stressing credit organization rather than the note issue alone. Mill gives the doctrine a classical form, first treating “forced accumulation” as anomalous and later incorporating it into the theory of credit: credit can redirect a given stock of goods toward productive employment, but the process is reversible once expansion stops.

The bridge to modern theory is Walras. Hayek emphasizes that Walras treated banknote issue not merely as a price-level question but as a claim that money creation may produce an apparent increase of capital. In this version, new money creates a demand for capital before a corresponding supply exists; the resulting rearrangement of consumption and investment anticipates later theories of interest, capital scarcity, and cyclical overextension. Wicksell then supplies the decisive modern setting by connecting forced saving with the divergence between the money rate and the equilibrium rate of interest.

Hayek’s last movement is from Wicksell to the twentieth century. Mises and Schumpeter incorporate the doctrine into German-language trade-cycle theory, where credit expansion above voluntary saving lengthens production and generates the conditions of later correction. In Cambridge, Robertson and Pigou recover a similar point under new terminology. Keynes, in Hayek’s account, rejects the inherited label but preserves the analytical problem when he describes investment as exceeding saving.

The moral and analytical force of the doctrine is captured by Bentham’s own conclusion:

Here, as in the above case of forced frugality, national wealth is increased at the expense of national comfort and national justice.

Hayek’s contribution is therefore not a new model but a disciplined genealogy. By following the doctrine from Bentham through classical, Walrasian, Wicksellian, Austrian, and Cambridge formulations, he shows that monetary expansion had long been understood as a way of compelling real saving through price and income effects. The note matters because it makes the theory of cycles appear less as an isolated Austrian innovation than as the latest articulation of a recurrent problem in monetary economics: how credit can temporarily finance investment by redistributing real resources before voluntary saving has caught up.
