Before Prices and Production made him famous in London, Hayek laid the foundations of his business-cycle theory in this 1929 monograph, here reissued with Kurt Leube's bibliography. Empirical research and statistics, he insists, can raise problems but never generate the causal laws of economics; only theory grounded in price, production, and interest can explain the cycle. Non-monetary accounts, whether technical, psychological, or built on disproportionality, fail because they smuggle in elastic credit while denying it any explanatory role. The engine is the Wicksell-Mises divergence between the money rate and the natural rate of interest: bank credit pushes lending below the equilibrium rate, lengthening the higher stages of production beyond what voluntary saving can sustain, until the boom's distorted capital structure collapses into crisis.

Solange wir uns des Mittels des Bankkredites bedienen, um die Entwicklung zu fördern, werden wir auch die Konjunkturschwankungen mit in Kauf nehmen müssen, die durch ihn verursacht werden.

English translation: “As long as we make use of bank credit as a means of promoting economic development, we shall also have to accept the cyclical fluctuations that it causes.”

The doctrine that thrift starves its own market—money saved being purchasing power withheld from consumers—found aggressive new champions in the American writers W. T. Foster and Waddill Catchings, popularized through the Pollak Foundation and its prize contests. Hayek dismantles their supposed paradox of saving by restoring the capital theory they lack. Saving does not simply pile output beside old output; it changes methods, withdrawing resources from immediate consumption toward intermediate and capital goods and lengthening the production process. Under a constant money stream, falling consumer-goods prices signal higher productivity, not underconsumption. Testing the claim across fixed capital, circulating capital and vertically integrated firms, he warns that the remedy Foster and Catchings urge—injecting new money through consumers or public works—would shorten production and destroy the very capital that saving forms.

Das einzige, was vor allem anderen nötig ist, um eine dauernde Aufwärtsbewegung der Wirtschaft zu sichern, ist genug Geld in den Händen der Verbraucher

English translation: “The one thing above all others required to secure a lasting upward movement of the economy is enough money in the hands of consumers.”

Reviewing Hans Neisser's Der Tauschwert des Geldes, Hayek praises a disciplined synthesis of German monetary theory while doubting the very object at its centre—the 'general' value of money and the price level. He approves Neisser's refusal to mistake Fisher's equation of exchange for a causal theory, treating it instead as a way of displaying the variables still to be explained, and singles out the analysis of credit money—bank deposits, cheque money, note-issuing banks, discount policy—as the book's finest achievement. Crucial to both men is that money represents 'pure demand,' not tied to a simultaneous supply of goods, and so 'acquires a life of its own.' Skeptical of velocity and aggregate magnitudes, Hayek uses the occasion to sharpen his own preference for a theory built on credit, cash demand and the coordinating role of interest.

Neisser very correctly emphasizes that the equation itself is very far from offering even a theory of the value of money.

Accused by Emil Lederer of reading his crisis writings superficially, Hayek replies by quoting them back at length—and finds in them the same underconsumptionist error he had charged against Foster and Catchings. Lederer explains general crisis as a gap between output and the purchasing power spent as income; accumulation, on this view, proceeds 'too fast' for consumer markets to realize profits. Hayek names this the Grundirrtum. Crises, he insists, come not when consumption is too small but when the structure of production is drawn into roundabout paths no longer justified by the relative demand for capital and consumer goods. Against Lederer's leaning toward credit-financed consumption and public works, he sets a preventive policy of braking the boom, since once malinvestment is done no curative Wunderkuren can undo it.

Eine solche Disproportionalität kann vielmehr meiner Ansicht nur darin bestehen, daß das Verhältnis des Kapitalgüterangebotes zum Konsumgüterangebot größer ist als das Verhältnis von Kapitalgüternachfrage zur Konsumgüternachfrage.

English translation: “Such a disproportionality can, in my view, consist rather only in the fact that the ratio of the supply of capital goods to the supply of consumer goods is greater than the ratio of the demand for capital goods to the demand for consumer goods.”

Can aggregate saving, investment, and profits explain a monetary crisis if they conceal what happens within production? In this two-part review of Keynes’s Treatise on Money, Hayek argues that monetary theory needs an account of capital committed through time. Profits near the point of consumption can coexist with losses further back in production; spending that maintains existing capital need not finance additional investment. These distinctions give concrete substance to his objections to Keynes’s definitions and equations. Hayek also credits Keynes’s analysis of deposit hoarding, making the review more than a statement of opposition. Readers can trace how disagreements over measurement become disagreements over depression: for Hayek, sustaining expenditure through credit may postpone the reallocation of resources required by unsustainable investments.

Long before the Austrians gave it a name, the mechanism had been discovered and lost under a dozen labels. This historiographical note traces the doctrine of "forced saving" — how new paper money or bank credit, entering through borrowers, temporarily shifts command over the existing flow of goods, so that rising prices and lagging incomes compel some to consume less while entrepreneurs invest more. Hayek finds the earliest clear statement in Jeremy Bentham's neglected manuscripts on "forced frugality," where monetary issue works like an indirect tax, and follows the thread through Thornton, Malthus, Mill, and Walras to Wicksell's gap between the money and natural rates of interest. Even Keynes, rejecting the label, preserves the problem when he describes investment exceeding saving. Cycle theory, the genealogy suggests, is less an Austrian novelty than a recurrent monetary insight.

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

In this essay, first published in 1932 as Kapitalaufzehrung and here in English translation, Hayek opens what he called an 'economics of decline', the neglected theory of how a society consumes its own capital. His claim is stark: production costs held too high, with wages pushed above equilibrium against rigid money incomes, can make current consumption exceed current output, so that capital is quietly eaten away. The process betrays itself through a shortening of the structure of production, a shift toward quickly finished consumer goods, and a fall in the value of capital equipment before any physical decay shows; depreciation funds go unreinvested and circulating capital becomes unrecoverable. Drawing on Austrian and central European evidence, including Morgenstern's data on Vienna-listed firms, he warns that democratic anti-capitalist majorities may favour levies and public works that devour the very capital they depend on.

What we are confronting here, however, are economic problems towards whose explanation economics has as yet made little direct contribution, even if it offers us the necessary tools for doing so.

A seventy-one-page pamphlet on price formation in the German scholarly antiquarian book trade, trailing a bibliography of theoretical works 'von Gossen bis Wicksell,' is exactly the mismatch of apparatus and achievement Hayek finds intolerable. His single-paragraph notice grants that the subject—rare, heterogeneous goods with widely dispersed valuations—could have been theoretically revealing, then denies that Bruck makes anything of it. The yield for price theory is meagre; the factual information is thinner than a regular reader of booksellers' catalogues could assemble unaided, especially on the two matters that would have mattered most: the movement of antiquarian prices over time and the 'Streuung' of simultaneous prices for identical works. The verdict is disciplinary—casual market observation, bibliographic display and genuine value theory are not the same thing, and Bruck has confused them.

Die preistheoretische Ausbeute ist recht mager.

English translation: “The yield for price theory is decidedly meagre.”

The gold standard did not fail of its own defects; it was disabled, and then blamed for failing. First published in 1932 and reissued here with two supplements because the same misunderstandings still shaped policy, Hayek's report pins the interwar monetary collapse on central banks, above all the Bank of England, that refused to let gold outflows force the domestic credit contraction and wage adjustment the system demanded. Britain's 1925 return to prewar parity left costs too high; cheap money and appeals for central-bank cooperation masked the weakness rather than curing it. Behind the crisis lies his attack on price-level stabilization: propping up prices that ought to fall with rising productivity is inflation by another name, breeding the misdirected production that made 1929 unavoidable.

All this means that there has not been too little but too much cooperation between central banks, and that not the gold standard, but efforts aimed at making the gold standard inoperative are the causes of the present monetary troubles.

The health of business-cycle research is measured, Hayek insists in this 1933 Festschrift essay, not by the mounting heap of contemporary statistics but by insight into causes—facts being the ever-changing object against which theory is tested, never its substitute. Crisis theory, he judges, has outrun the theory of depression. He gathers the Wicksellian, Misesian and Spiethoffian strands into one diagnosis: credit expansion unbacked by voluntary saving lengthens and distorts the structure of production, and the resulting 'capital shortage' is identical with relative overconsumption. What remains unsolved is recovery—how relative prices, stocks and the direction of resources must be revalued, and how to distinguish price falls that undo prior maladjustment from secondary deflation that persists past its use. Capital maintenance, wage rigidity, expectations and cash balances he names as the field's next work.

Written in the spring of 1933, as Hitler consolidated power, this short essay confronts a comforting misreading head-on: that National Socialism was a conservative or capitalist reaction. Hayek argues the opposite, that it was a genuinely socialist and collectivist movement, the ripened fruit of an anti-liberal current running through German thought since the Bismarckian era. Its hostility to the Marxist parties, he contends, was national and cultural rather than economic, while its intellectual debts ran to Marxian relativism and anti-rationalism. Tracing how collectivist planning tends toward coercion, the suppression of intellectual freedom, and finally dictatorship, he warns that other Western nations expanding state control over economic life court the same descent. A compact statement of the themes Hayek would enlarge a decade later in The Road to Serfdom.

The inherent logic of collectivism makes it impossible to confine it to a limited sphere.

Why might economists oppose reforms whose humanitarian aims they share? In this 1933 inaugural lecture at the London School of Economics, Hayek locates the tension in the difference between intentions and consequences—and in the delayed influence of economic ideas on public opinion. His account of the Historical School argues that objections to intervention were often forgotten rather than refuted. Yet his defence of theory is not an unconditional defence of laissez-faire: economists must also identify useful government action. A concrete example gives the argument its force. Whether to retain old machinery or replace it depends not simply on technical efficiency, but on the competing uses of capital and other resources. The lecture shows how Hayek connects apparently wasteful individual decisions with coordination across an economy, while separating agreement about social purposes from agreement about policy.
