If the United States has a comparative advantage in steel, should it abandon wheat production and depend on Luxembourg’s harvest? Haberler uses this deliberately disproportionate pairing to distinguish gains from trade from the demand for complete specialization. In this 1929 article, his defence of comparative cost proceeds by limiting what the principle claims: money prices do not overturn comparative advantage, but production costs alone cannot determine which goods a country exports and imports. Answering James W. Angell and A. F. Burns, Haberler separates genuine qualifications from supposed refutations. Readers can discover how a classical proposition survives these objections through sharper distinctions—while Haberler leaves unresolved the deeper problem of its reliance on a labour theory of value.

What distinguishes international trade from exchange within a country: different currencies, or also the conditions governing the movement of labor and capital? In this brief review of E. Melchinger’s study of international price formation, Gottfried Haberler credits the book’s intellectual ability while challenging its narrow monetary definition of international trade. His phrase “alleged immobility” treats barriers to factor movement as something to investigate, not simply assume. He also finds a gap between Melchinger’s conceptual discussion and his treatment of concrete trade problems. The review offers a compact glimpse of Haberler’s critical priorities: broader explanatory scope, clearer exposition, and a stronger connection between theoretical distinctions and their applications.

Does explaining why firms hold cash make counting how often money changes hands redundant? In this English-language review of M. W. Holtrop’s Dutch monograph, Gottfried Haberler separates the merits of a causal explanation from the rejection of an alternative accounting description. He welcomes Holtrop’s attention to payment schedules, uneven receipts and expenditures, and credit instruments, but disputes his insistence that cash-reserve and movement theories are incompatible. The disagreement becomes concrete when production is divided among several firms: additional transactions can increase the demand for money, with consequences for prices. This brief review offers a precise encounter between monetary theory and business finance, showing why Haberler values an explanation of cash holdings without abandoning velocity as a useful measure of monetary supply.

Comparative advantage, not absolute superiority, is what makes trade pay — a country gains by exporting where its disadvantage is least and importing where it is greatest, even against a rival more efficient at everything. This essay rebuilds that classical theorem on firmer ground, replacing Ricardo's labour theory of value with opportunity cost: the real cost of more of one good is the quantity of another forgone along a substitution curve. Haberler then extends the argument from two goods to many, ranking commodities along a shifting export-import margin set by wages, exchange rates and the balance of payments. He turns the framework against the case for retaliatory tariffs and against protectionist appeals to immobile capital, arguing that idle plant and written-down assets are private losses, not proof of national waste.

Unilateral free trade is thus—tactical considerations aside—thoroughly desirable and preferable to a generalized tariff regimen.

How does a country saddled with reparations actually hand real resources across its borders, and must its export prices fall to do so? That question, sharpened by Germany's post-Versailles burden, sets Haberler against Bertil Ohlin in these two essays, translated from the 1930 article and its 1931 rejoinder. Endorsing the Thornton-Mill view that price movements are almost always needed to force the required export surplus, he nonetheless refuses the standard conclusion that the terms of trade must turn against the payer, showing that they can conceivably improve. Against Keynes's transfer pessimism he judges a demand elasticity of one or less for German exports highly improbable, given Germany's competitive industries and small share of world markets, while carefully separating the international transfer problem from the domestic fiscal task of raising the sums.

One could say, therefore, that Keynes was right in theory but his opponents in practice.

Can a comprehensive account of international trade explain much if its basic concepts are unstable? In this 1931 review of Franz Eulenburg’s Aussenhandel und Aussenhandelspolitik, Gottfried Haberler tests a broad historical and policy survey against exacting theoretical standards. His distinction between selling cheaply abroad and charging different prices at home and abroad makes the stakes concrete: an account of dumping can fail at the level of definition. He likewise objects to tariff analysis that precedes an adequate explanation of comparative costs. While acknowledging useful historical material, Haberler argues that facts require a coherent explanatory framework. This brief, sharply critical review shows what he demands of trade scholarship—and why, for him, theoretical order is more than a matter of presentation.

Stable prices need not mean a stable economy: this is the challenge Gottfried Haberler foregrounds in his 1931 review of Hayek’s Geldtheorie und Konjunkturtheorie. He explains how bank credit can permit investment to outrun real saving without producing a visible rise in the general price level. Yet his sympathetic assessment also finds room for non-monetary explanations: invention or optimism may initiate an expansion that credit makes possible. Haberler’s distinctive contribution lies in separating the initiating event from its monetary enabling condition, rather than insisting on rival theoretical labels. He also marks what Hayek’s book leaves unresolved—how distorted investment culminates in crisis—making this short review an appraisal of both the reach and the limits of the explanation.

A theory of interest can be logically coherent yet leave the workings of investment and banking underexplained. This tension guides Gottfried Haberler’s review of Irving Fisher’s Theory of Interest. Haberler credits Fisher with bringing impatience and investment opportunity into a unified account, while questioning whether its abstract framework sufficiently explains production, capital accumulation, and monetary disturbances. His criticism is also conciliatory: he finds the disagreement between Fisher and Böhm-Bawerk smaller than their polemics suggest. Concrete conceptual tests sharpen the review—can money expenditure measure enjoyment, and does deferred pleasure really distinguish investment from consumption? Readers encounter both a careful appraisal of Fisher and Haberler’s case for connecting interest theory more closely to economic choices, production periods, and bank credit.

Haberler delivered this lecture with the Depression as backdrop, but treats panics, bank failures and crashes as secondary drama; the real object of explanation is the recurrent rhythm of expansion and contraction in business activity. Money is a necessary condition of the cycle, though not in the crude quantity-theory sense: stable prices in the 1920s, he argues, concealed a "relative inflation" in which credit expansion masked the fall that rising productivity should have produced. The decisive shift is from the level of prices to the vertical structure of production. When bank credit pushes the market rate of interest below the rate warranted by voluntary saving, entrepreneurs lengthen production into more roundabout, capital-intensive projects that consumers have not chosen to fund — a maladjustment that the depression, painfully, corrects. Reflation aimed merely at purchasing power risks reviving the very disproportions that need liquidating.

The fundamental appearance of the business cycle is a wavelike movement of business activity

Must workers displaced by machinery accept lower money wages before they can find employment again? In this short 1932 intervention, Gottfried Haberler challenges Alvin Hansen’s claim that unemployed workers’ lost purchasing power cancels consumers’ gains from cheaper goods. His distinctive move is to follow money through successive payments: eliminating one stage of expenditure can bring demand to other producers sooner. Haberler argues that, with money quantity and circulation velocity unchanged, reemployment need not require lower equilibrium money wages. The value of this tightly focused dispute lies in the distinctions it forces: technological displacement is not monetary contraction, and an equilibrium result is not a promise of painless adjustment. Haberler explicitly leaves room for losses and frictions as workers move between industries.

Defending free trade, Haberler argues, requires admitting that tariffs can sometimes confer benefits—even on a country as a whole. In this 1932 review of the committee report chaired by Sir William Beveridge, he praises a method that concedes theoretical possibilities while testing how plausible their conditions are in practice. His concern is both analytical and persuasive: absolute claims leave free traders vulnerable to objections they have failed to answer. Britain’s departure from gold gives that distinction a concrete setting, removing, in his assessment, the basis for Keynes’s proposal to use tariffs instead of devaluation or wage reductions. This short review shows why Haberler regarded qualification not as a retreat from free trade but as a condition of its credible defense.

Here in the English translation of Haberler's 1933 Der internationale Handel, the whole of foreign trade is folded into general price theory: exchange rates are prices formed by supply and demand, balances of payments are not autonomous magnitudes, and comparative advantage is rebuilt on opportunity cost rather than the labour theory of value. The treatise runs from the foreign-exchange market and the gold standard through the transfer problem — with extended treatment of German reparations and the Keynes-Ohlin controversy — to a systematic anatomy of commercial policy: tariffs, dumping, cartels, infant-industry claims and quotas. Throughout, protection is judged by its hidden diversion of resources and its costs to consumers and exporters, not by the visible survival of sheltered industries. Haberler reserves his sharpest hostility for quantitative restrictions, which suppress the price mechanism more arbitrarily than any duty.

It is the increase and not the reduction of duties which is the real economic burden!
