A generation of development economists held that primary-product exporters face an inexorable secular decline in their terms of trade, and thus a standing case for protection and industrialization. Haberler subjects that thesis to sustained scrutiny and finds it wanting: the historical evidence is thin, neglects quality improvements, new manufactured goods, and freight costs, and confuses a fall in commodity prices with a fall in welfare. Distinguishing commodity from single factorial terms of trade, he shows that cheaper exports need not mean loss where export productivity has risen, and he treats the cyclical instability of raw-material prices as real but exaggerated by the freak experience of the 1930s. His remedy is not buffer stocks and commodity agreements but financial discipline—reserves accumulated in booms and drawn down in slumps.

It is well known that the hypothesis under consideration is based entirely on the annual index of the United Kingdom's commodity terms of trade.

Between the wars, the restored gold standard was never the specie standard of 1914 but a fragile gold-exchange construction, hobbled by an overvalued pound, an undervalued franc, reparations, and the sterilization of gold in Paris and Washington. Tracing its restoration after 1923 and its collapse across the United States, Britain, Germany, France, and Japan, Haberler—here in the English translation of his 1976 German essay—argues that the Great Depression was no ordinary cyclical downswing but the product of banking failures, timid central banks, and the adjustable peg that turned devaluation into competitive depreciation. He weighs Hayek and Robbins's Austrian theory of credit-induced malinvestment against Hansen's secular stagnation and the structural-maladjustment school, and closes by contrasting the deflationary 1930s with the inflationary crisis of the 1970s.

If a death certificate for the gold standard is required, September 21, 1931 would be a reasonable date to put on it.

Ricardo's wine-and-cloth doctrine, stripped of its labour theory of value and restated in general-equilibrium and welfare terms, still governs agriculture and primary exports, so Haberler argues against a mid-century development economics eager to bury it. He grants that perfect competition and the absence of externalities never fully hold, but denies that the sheer pervasiveness of such impurities refutes the theory. Point by point he dismantles the objections: the ECLA-Kaldor claim that farm exporters face monopolistic industrial sellers, the Prebisch-Singer thesis of secularly deteriorating terms of trade, which he shows unsupported by Lipsey's data, and the notion of agricultural labour with zero marginal product. His one real concession is the genuine external economy of training a skilled, supervisory, and entrepreneurial workforce, the only sound version of the infant-industry case.

But no theory, however complicated and refined, can offer more than a simplified or idealized picture of the infinite complexities of the real world.

Whether the non-communist economies would return to multilateral liberal trade or settle into a managed world of controls, quotas, and currency blocs was, in 1954, the question convertibility decided. Haberler first clears the definitional ground, separating full from partial convertibility, resident from nonresident rights, and current from capital transactions, because governments can proclaim liberalization while preserving discrimination through licensing and blocked balances. His normative claim is that convertibility is the monetary form of free trade, letting countries specialize by comparative efficiency instead of matching imports to exports bilaterally. The failed 1947 sterling experiment serves as his warning: it collapsed not because convertibility is unworkable but because inflation and an overvalued pound made it so. Rejecting gold-standard deflation, he favors monetary discipline joined to freely floating rates over the speculation-prone Bretton Woods peg.

It cannot be repeated too often that any form of open or repressed inflation is incompatible with convertibility and stable exchange rates.

American trade policy of the 1950s contained a puzzle Haberler sets out to resolve: Washington condemned imperial preferences and discriminatory tariffs while applauding customs unions, even though a customs union discriminates against outsiders more sharply than a mere preference does. His resolution turns on economic effect rather than the degree of discrimination. A preferential regime keeps separate national tariffs and invites product-by-product bargaining and capture by protected interests; a complete customs union abolishes internal barriers wholesale, adopts a common external tariff, and is far likelier to create trade than to divert it. He judges genuine unions rare, Benelux being the modern instance, and insists Japan's viability depends on worldwide markets rather than an Asian bloc, holding throughout to multilateralism and the most-favoured-nation clause.

If tariff preferences are bad because they imply discrimination, then a customs union should be worse because it implies a higher degree of discrimination.

A uniform tax on all imports plus an equal subsidy on all exports is, for commodity trade, identical to a currency devaluation, an equivalence Haberler accepts as an analytical benchmark and then spends the chapter refusing as policy. The device breaks the moment it meets institutions: it omits services and tourism, invites exemptions, and never stays uniform, sliding toward commodity-by-commodity and country-by-country discrimination and, eventually, exchange control. On the microeconomic side he wields Ricardo to reject the GATT distinction between border-adjustable indirect taxes and non-adjustable direct ones; what matters is whether a tax alters relative costs, not whether it is nominally shifted. Tracing the idea from Keynes's 1931 tariff-and-bounty proposal through Hicks, Triffin, and European VAT practice, he concludes that a valid model equivalence is no sound recommendation.

I conclude that the border tax on imports and tax refund on exports is an inferior, messy, wasteful, and inefficient substitute for exchange-rate adjustments.

Development is ordinary economics practised under difficult conditions, not a separate discipline licensing illiberal policy. From that premise Haberler, writing as a trade theorist, prosecutes the anti-market doctrines that captured the postwar field: import substitution, exchange control, the big push, and chronic trade pessimism. He traces their appeal to a fatal misreading of the Great Depression, which he insists was a monetary catastrophe rather than proof of capitalist stagnation, and to an aggregation that lumped unlike countries together. The Prebisch-Singer terms-of-trade thesis he rejects with Lipsey's evidence; the demonstration effect he calls patronizing; disguised unemployment he answers with Viner and Schultz. His comparisons, West Germany against East, South Korea against North, Taiwan against China, turn the chapter into a broad indictment of planning, defending monoeconomics throughout.

The best policy would be to let free markets, in other words, capitalism, do what they do best – develop new industries.

Pure free trade is politically rare and even theory admits exceptions to it, so the question Haberler pursues is not whether governments intervene but how. The form decides everything. A tariff is visible, general, price-based, and pours revenue into the treasury; a quota fixes volume by fiat and mints scarcity rents for whoever holds the license; worse still, a voluntary export restraint, like the one pressed on Japanese carmakers, ships that rent abroad. Around the surviving GATT core of most-favoured-nation treatment he charts a proliferating tangle of preferences, origin rules, and discretionary licensing, with agricultural protection, above all the self-contradicting sugar program, as his sharpest case. Where quotas cannot be abolished he would auction the licenses. His liberalism is institutional: rules and transparency against the administrative sprawl of managed trade.

But the élan of trade liberalization of the first 15 or 20 years of the postwar period has evaporated.

A quota is not a tariff by another name, even when both cut imports to the same level: where a duty preserves market allocation, price contact between countries, and revenue for the treasury, a quantitative control rigidly fixes quantities, breeds monopoly and quota rents, and shifts power from legislatures to administrators. Written in 1943 with an eye to the postwar settlement, this study traces how licensing born of wartime scarcity hardened, through the sterling crisis and the gold bloc's defensive measures, into a standing tool of protection, retaliation, and bilateral bargaining that fragmented 1930s trade. Haberler roots the persistence of controls in monetary instability and political insecurity, and sets the Atlantic Charter's promise of equal access against the drift toward autarky, warning that a tightly controlled trade system cannot long coexist with a free domestic economy.

From being isolated measures to limit the importation of a few specific commodities, they came to be consciously used in many countries as a general instrument of protection.

International trade is governed proximately by money prices and money costs, yet exchange-rate complications and pre-trade cost comparisons make the doctrine of comparative advantage easy to misread. Setting the Marshall-Viner real-cost approach against opportunity cost—which he defends as a workable approximation to general-equilibrium theory—Haberler concedes that increasing returns, monopoly, wage rigidity, and external economies all qualify the free-trade case, then argues that liberal policy remains preferable precisely because interventionist systems obscure the comparative costs on which rational choice depends. The paired concluding remarks turn to the postwar dollar shortage, where he sides with the optimists against structural pessimism, credits the 1949 sterling devaluation and disinflation with vindicating the classical adjustment mechanism, and rejects discriminatory restrictions against dollar goods in favour of non-discrimination and the most-favoured-nation principle.

Non-discrimination like honesty still remains the best policy.

Haberler builds the theory of comparative cost from a two-country, two-commodity opportunity-cost model, then presses on the imperfections that critics invoke to justify protection. A mere catalogue of deviations from the competitive ideal, he insists, proves only possibility, not necessity: factor immobility alone leaves trade welfare-improving so long as factor prices stay flexible, and it is rigid wages—especially those maintained by unions—that generate the unemployment which can make trade inferior to autarky. Even then protection is a second-best, largely short-run remedy. He extends the same discipline to external economies, showing how unrecognised ones can make a country appear to hold a comparative advantage in the wrong commodity, and to the infant-industry argument, which he accepts in principle while noting it can equally counsel freer trade.

It can be easily shown, however, that what really causes trouble and may make trade detrimental and justify protection is rigidity of factor prices, which may or may not be associated with immobility of factors.

Aid to poor countries is laudable; producing it by attaching international reserve creation to development finance is not. That is the disciplined case Haberler mounts against the "Link" between IMF special drawing rights and assistance to less developed countries. Reserve allocation answers to payments, trade variability, and liquidity, he argues, while aid answers to income, wealth, and welfare; fusing the two would rationalize neither and turn every SDR decision into a distributive struggle. The Link is inherently inflationary, since reserves allocated for development are designed to be spent, and even the subtler non-inflationary version proposed by Karlik and Scitovsky would yield little. Aid should instead be voted openly through the budget, its burden made explicit rather than scattered by IMF quotas and balance-of-payments accidents - a tax lottery in place of a tax system.

This argument again mixes reserves and aid.
