Investment can create the demand that seems to vindicate it—but what happens when businesses begin to expect that demand to keep rising? In this 1938 monograph, G. L. S. Shackle turns Keynesian analysis toward the passage of time, making expectations change in response to the outcomes of entrepreneurs’ own collective decisions. Firms act separately, yet the incomes their projects generate can encourage further construction and draw investment plans into a common rhythm. Shackle locates a possible source of reversal not in exhausted resources but in a shortage of entrepreneurs ready with their next executable project. His account gives readers a concrete way to distinguish profitable opportunities from the capacity to act on them, and to see how apparently confirming experience can prepare the disappointment that ends a boom.

The vocabulary of freedom, Hayek warns, has been turned inside out — "liberalism" now names the restrictions that collectivists promise will free men from want. Written on the eve of war and anticipating The Road to Serfdom, this Chicago pamphlet argues that comprehensive planning threatens the liberties it claims to enlarge. Its logic is institutional, not conspiratorial: directing all economic life requires agreement on a ranked scale of social ends that plural societies simply lack, so planners must impose values and then manufacture belief in them. Prices, by contrast, combine dispersed knowledge no single mind commands. Because whoever controls the means controls the ends they serve, economic dictatorship cannot stay merely economic — propaganda and the suppression of dissent become essential parts of the system. Only competitive capitalism, he contends, keeps democracy from having to decide everything, and so from destroying itself.

Freedom and liberalism have become terms that are used to describe the exact opposite of their historic meaning.

Agreement that society should be more just does not settle whose needs should take precedence when resources are scarce. In this 1938 article, republished in 1997, Friedrich August von Hayek makes that gap central to his critique of comprehensive economic planning. He acknowledges the socialist ambition to enlarge freedom, but argues that centrally directing individual activities requires a ranking of purposes on which democratic citizens cannot agree. Delegating decisions to experts cannot resolve this conflict of values; in his account, it instead encourages unchecked authority and the suppression of dissent. The article offers a pointed connection between economic allocation and intellectual liberty: readers can examine why Hayek regards disagreement not as an obstacle to social reason, but as one of its necessary conditions.

Prosperity can undermine the investment that set it in motion. In “Investment and Costs of Production,” Ludwig Lachmann explains how rising consumption can increase construction costs without improving the expected long-term returns on durable assets. His distinctive move is to examine relative profitability rather than aggregate income: unemployed workers and idle machinery do not eliminate shortages of the particular skills and equipment a project requires. Readers can discover why cheap credit may fail to overcome these bottlenecks—and why commodity speculation may accelerate the cost increases that discourage investment. The article develops a qualified defence of Austrian cycle theory, while refusing to infer that falling costs will necessarily restart interrupted production. Its central tension is between an expansion’s apparent resources and the specific combinations needed to sustain it.

If saving and investment are equal by definition, what can their equality explain? In this 1938 essay, Gottfried Haberler separates an accounting identity from the monetary processes and changing plans that business-cycle theory must explain. His engagement with Keynes is discriminating: he accepts the saving–investment identity while challenging its use as an explanation of adjustment. The same concern for conceptual precision shapes his treatment of national income as a welfare measure. More medical spending need not mean better health, and government services cannot all be counted alike without risking duplication or misleading valuation. Readers can discover why welfare appraisal, causal explanation, and statistical estimation require different definitions—and why a discrepancy between measured saving and investment need not establish economic disequilibrium.

Every government that gathered at Geneva professed the Cobdenite creed that commerce breeds peace; every government, called to concrete concessions, reached instead for the tariff, the quota, and the bargaining duty. Delivered as the Cobden Lectures at the London School of Economics in February 1938, these three lectures reconstruct two decades of League conferences—Brussels, Genoa, the bold 1927 resolution to halt and reverse the rise of tariffs, the wrecked London gathering of 1933—and ask why they failed. Rappard sorts the protectionist arguments by purpose rather than chronology, weighing infant-industry claims and agrarian defenses, and locates the deepest cause not in ignorance or private greed but in the fear of war, which drove nations toward autarky. From Geneva, he warns, no honest message of optimism can come.

Thus those who could, will not, and those who would, cannot.

Can falling prices deepen a depression, while rising prices undermine recovery? In this 1938 article, Emil Lederer refuses to choose between correcting price imbalances and stimulating investment. He argues that flexible prices can accelerate contraction as falling wages and receipts erode demand, while particular rigid prices—especially those of steel and building materials—can make new investment prohibitively costly. Drawing on price and production evidence from 1929–1937, he distinguishes rigidity that restrains deflation from rigidity that obstructs expansion. The resulting policy tension is concrete: public works may launch recovery yet raise the material costs that discourage private projects. Readers encounter an analysis of why stimulus must attend not only to how much is spent, but also to the prices and production costs through which spending takes effect.

Japan’s industrial expansion looks different when low wages and depressed farm incomes enter the explanation. Reviewing the July 1937 Japan issue of Weltwirtschaftliches Archiv, Emil Lederer values its economic evidence while questioning the political assumptions that shape its interpretation. His criticism becomes concrete in the conflict over rice prices: cheap rice helps sustain low industrial wages, but threatens farmers’ livelihoods; support for farmers puts pressure on workers’ real incomes. Rather than dismissing the collection as propaganda, Lederer distinguishes its empirical strengths from its neglect of competing social interests and peaceful alternatives to territorial expansion. This short review offers a pointed example of how a critic can use a publication’s own evidence to challenge the national necessities its contributors take for granted.

What makes an annotated statute useful as a record of legal change? In this brief review, Helene Lieser singles out the earlier Austrian laws appended to Edmund Prochaska’s edition of the new Czechoslovak instalment-transactions law. Her approval rests on that juxtaposition: current legislation becomes clearer when its predecessors are available alongside it. The notice records a concise judgment about legal documentation rather than an assessment of particular statutory provisions.

Confusion about the calculus, the authors contend, usually springs not from calculus itself but from shaky command of the algebra, geometry, and limits beneath it. Written for beginners rather than as a treatise on mathematical economics, this primer builds from graphing total cost against output toward the ideas an economist must handle to read the published literature: the limit, the derivative, marginal cost and marginal utility as special cases of it, maxima and minima, Lagrange multipliers for constrained cost minimization, Euler's theorem and the exhaustion of product under competition, least-squares regression, and Cramer's rule for market equilibrium. W. L. Crum credits Joseph Schumpeter with the volume's major additions, and the economic example — never abstract rigor for its own sake — governs every step.

The derivative of $y$ with respect to $x$ is the instantaneous rate of change of $y$ with $x$.

Can an economy hoard money even when its total cash holdings remain unchanged? In this reply to R. F. Kahn’s review of Prosperity and Depression, Gottfried Haberler argues that it can: expenditure and income may fall without any reduction in the money stock. This distinction anchors his defence of a monetary account of economic fluctuations against Kahn’s criticisms. Haberler’s distinctive concern is to separate differences of vocabulary from differences of explanation—especially where saving–investment identities threaten to substitute for accounts of how adjustment occurs. His qualified acceptance of public works sharpens the stakes: additional government spending must increase total demand, not merely displace expenditure elsewhere. The reply offers a focused encounter with the contested boundary between monetary circulation, effective demand, and the financing of recovery.

Confident opinion at the turn of the century assumed democracy's advance was as irreversible as the tide; by 1938 Bolshevism, Fascism, and National Socialism had made that assumption look naive. Across six lectures given on the Harris Foundation at Chicago, Rappard defines democracy not by its etymology but by the paired ideals of liberty and equality, then traces its uneven rise from Athens through Britain, France, and his native Switzerland. He reads the three great dictatorships as offspring of the World War—Lenin's from defeat, Mussolini's from disappointed victory, Hitler's from Versailles and slump—and diagnoses the strain within surviving democracies as a crisis of parliamentarism rather than of democracy itself. The remedy he presses is unfashionable: a retreat of the state from economic life, without which self-government becomes an illusion.

Democracy thrives on peace, and dictatorships on war.
