Selected essays of Gottfried Haberler

[Front Matter and Table of Contents]: Front matter for the 'Selected essays of Gottfried Haberler' (1985), including the title page, copyright information, dedication, and a detailed table of contents. The table of contents organizes Haberler's work into five major sections: International Trade, International Finance, Inflation and Business Cycles, Economic Development, and Money/Real Balance Effect. [Editor's Preface]: Editor Anthony Y. C. Koo describes the selection process for this volume, noting that Haberler's work spans over fifty years. He highlights the inclusion of four previously untranslated German articles, including Haberler's first publication on Schumpeter's theory of money, and mentions the addition of postscripts reflecting Haberler's 1984 perspectives. [The Theory of Comparative Costs and Its Use in the Defense of Free Trade]: Haberler defends the doctrine of free trade by refining the theory of comparative costs. He argues that free trade is beneficial even without international labor mobility. Crucially, he reformulates the theory to be independent of the classical labor theory of value, using the Austrian concept of opportunity cost and substitution curves. He addresses objections regarding many-commodity models, the alleged harm of unilateral free trade, and the 'frictional losses' associated with shifting production, arguing that unused specific factors are a sign of progress rather than a reason for protectionism. [Postscript and Footnotes to Comparative Cost Paper]: A postscript by Haberler providing references to his later developments of the comparative cost theory, followed by detailed bibliographic and explanatory footnotes for the preceding essay. The notes discuss the history of the theory (Ricardo, Torrens), critiques by Pareto and Ohlin, and the integration of the Austrian cost concept. [Real Cost, Money Cost, and Comparative Advantage]: Haberler examines the relationship between money prices and 'real' costs in international trade. He critiques the subjective real cost theory (Marshall-Viner) in favor of the opportunity cost approach. He explores how market imperfections—such as monopolistic elements, wage rigidities, and lack of factor indifference—affect the validity of the free trade doctrine. He concludes that while the ideal conditions for free trade are never perfectly met, the market mechanism remains superior to the haphazard interventions of modern protectionism. [Introduction to the International Economic Association Round Table]: Haberler introduces the International Economic Association's first round table, defending the scientific study of politically charged economic topics. He argues that practical problems, such as post-war monetary disorders, historically stimulate significant advancements in economic theory. [Short Run and Long Run Disequilibria in the Balance of Payments]: This section analyzes the 'dollar shortage' following World War II, contrasting 'pessimist' views focused on chronic structural changes with 'optimist' views (held by Haberler) that favor 'classical medicine'—disinflation and realistic exchange rates. Haberler discusses Keynes's shifting views on trade elasticity and argues that the 1949 devaluations proved the efficacy of orthodox adjustment policies. [The Problem of Discrimination in International Trade]: Haberler examines the economic and political arguments for discriminatory trade practices, such as quotas and preferential tariffs. He critiques the 'pessimist' reliance on discrimination to protect terms of trade, arguing that such policies invite retaliation, reduce world income, and are administratively unworkable compared to non-discriminatory methods like devaluation. [Notes and Commentary on International Trade Theory]: A collection of detailed endnotes providing theoretical depth to the preceding essay. Topics include the debate between Viner and Haberler on real vs. opportunity costs, the application of welfare functions in economics, the limitations of the 'Theory of Games' in 1949, and the technical distinctions between discrimination and non-discriminatory protectionism. [Some Problems in the Pure Theory of International Trade: Introduction and Basic Model]: Haberler introduces an essay on the pure theory of international trade, framing it as an application of welfare economics using the opportunity cost doctrine. He establishes a two-country, two-commodity model using a production opportunity curve (concave to the origin) to represent increasing opportunity costs. He emphasizes the critical distinction between the exchange ratio (price ratio) and the marginal transformation ratio, noting that they only coincide under conditions of perfect competition and factor mobility. [Trade Specialization and Welfare Criteria]: The segment analyzes how a country specializes in production when trade is opened, moving the production point to where the marginal transformation ratio equals the international exchange ratio. Haberler discusses the determination of the trading point via demand conditions and critiques the use of community indifference curves. He argues that trade is 'superior' if it allows for a larger national income such that, through potential redistribution, every individual could be made better off (the compensation criterion). [Market Imperfections and Factor Immobility]: Haberler examines deviations from the ideal free-trade model, specifically focusing on factor immobility and price rigidity. He argues that while factor immobility alone does not necessarily make trade detrimental, the combination of immobility and rigid factor prices (wages) can lead to unemployment and a reduction in national welfare. In such cases of 'distortion,' protectionist measures might be theoretically justified as a second-best solution to restore the status quo ante. [Involuntary Unemployment and Social vs. Private Cost]: This section explores the mechanics of production contraction under rigid prices and the distinction between voluntary and involuntary unemployment. Haberler explains that when factor prices are rigid, the price ratio fails to equal the marginal rate of transformation, creating a divergence between private and social costs. He notes that trade can be detrimental if the resulting unemployment outweighs the gains from improved terms of trade, though this is a possibility rather than a necessity. [Short-run vs. Long-run Adaptability and Externalities]: Haberler compares different transformation curves representing varying degrees of factor mobility and price flexibility. He then transitions to the problem of external economies and diseconomies, where the private cost ratio diverges from the social transformation ratio. Using diagrams, he illustrates Frank Graham's case where a country might specialize in the 'wrong' commodity due to unrecognized external economies in a specific industry, potentially making trade detrimental. [The Infant-Industry Argument and Historical Perspective]: The essay concludes with an analysis of the infant-industry argument. Haberler describes this as a movement along a production-opportunity curve that causes an irreversible outward shift of the curve itself over time. While acknowledging the theoretical validity of the argument, he expresses skepticism regarding its practical application, noting that external economies can exist in export industries as well as import-competing ones, and citing the caution of empirical researchers like Marshall and Taussig. [Notes on Pure Theory of International Trade]: Comprehensive footnotes for the preceding essay. They include a defense of the opportunity cost doctrine against Viner and Samuelson, a discussion of the compensation criterion in welfare economics, and technical elaborations on the 'Manoïlesco case' regarding wage differentials and domestic distortions. The notes also reference the Graham-Knight controversy and modern refinements by Bhagwati, Ramaswami, and H.G. Johnson. [The Theory of International Trade: Introduction and Definitions]: This introductory section defines international economic transactions and explores the distinguishing characteristics of foreign versus domestic trade. Haberler identifies four main factors: international immobility of production factors, independent monetary systems, political regulations (tariffs/quotas), and geographic distance/transport costs. He discusses the relationship between trade theory and location theory, suggesting that trade theory is a higher-level abstraction that will eventually be integrated into a general equilibrium system of location. [The Classical Theory of Comparative Costs: Hume to Ricardo]: Haberler traces the history of international trade doctrine starting with the classical school. He highlights Hume's work on the international monetary mechanism and Adam Smith's arguments for the division of labor. The core of the section is David Ricardo's theory of comparative costs, explained through the famous wine and cloth example. Haberler notes the simplifying assumptions of the Ricardian model, including the labor theory of value and factor immobility, and how these were later refined. [Refinements of International Value: Mill and Marshall]: This segment discusses the evolution of the theory of international values. John Stuart Mill introduced the role of demand in determining the terms of trade, which Alfred Marshall later formalized using reciprocal demand and supply curves. Haberler explains the complexity of Marshall's 'representative commodity bales' and mentions extensions of the model to multiple countries and commodities by Mangoldt, Graham, and Lösch, focusing on how equilibrium determines the composition of trade. [Modern Developments of the Pure Theory: Real Cost vs. Opportunity Cost]: Haberler critiques the classical labor theory of value for its unrealistic assumptions regarding factor homogeneity and mobility. He contrasts the 'real cost' approach of Taussig and Viner with the modern application of opportunity costs and general equilibrium theory. He argues that under 'ideal' conditions of free competition, the exchange ratio between commodities equals the marginal rate of substitution, preserving classical conclusions without requiring the labor theory of value. [Welfare Economics and Analytical Tools in Trade Theory]: This section explores the intersection of trade theory and modern welfare economics, defining 'optimum' in the Paretian sense of efficient resource allocation. Haberler introduces key analytical tools such as the transformation (production possibility) curve and the community indifference curve. He notes the theoretical difficulties in constructing collective utility curves and mentions the mathematical reformulations of trade theory by Yntema, Mosak, and Meade. [The Ohlin Model and Factor Price Equalization]: Haberler examines Bertil Ohlin's general equilibrium approach, which focuses on differential factor endowments and money costs rather than labor units. A significant portion is dedicated to the Heckscher-Ohlin law of factor price equalization. Haberler critiques the Lerner-Samuelson version of this theory, arguing that its conclusion of complete equalization rests on highly restrictive and unrealistic assumptions, such as identical production functions and incomplete specialization. [The Leontief Paradox and Income Distribution]: Haberler discusses the impact of trade on functional income distribution, specifically the Stolper-Samuelson theorem regarding scarce factors. He then addresses the 'Leontief Paradox'—the empirical finding that U.S. exports are labor-intensive despite the country's capital abundance. Haberler suggests reconciling this with traditional theory by considering a many-factor model where American labor is more productive due to superior management and natural resources, or where capital acts as a substitute for scarce natural resources. [The Terms of Trade: Definitions and Measurement]: This section defines various concepts of the 'terms of trade,' distinguishing between commodity (barter), single factorial, and double factorial terms. Haberler explains the difficulty of measuring factorial terms due to productivity index complexities. He critiques the 'gross barter' and 'income' terms of trade, arguing that the simple commodity terms of trade is often a more reliable indicator of welfare changes, provided one distinguishes between shifts in foreign demand versus a country's own offer curve. [The Balance of Payments Mechanism and National Income Accounting]: Haberler provides a framework for the balance of payments, distinguishing between current and capital accounts. He integrates the balance of payments into national income accounting, emphasizing the distinction between national income (Y), volume of production (P), and total expenditure or 'absorption' (V). He notes that in an open economy, these three aggregates are not identical, particularly when foreign aid or capital transfers are involved. [Price and Income Effects in Balance of Payments Adjustment]: Haberler analyzes the mechanisms for reestablishing balance of payments equilibrium: stable exchange rates (gold standard), fluctuating rates (devaluation), and exchange control. He discusses the 'income effect' via the marginal propensity to import and the 'price effect' via elasticities. He critiques 'elasticity pessimism,' arguing that statistical methods often underestimate actual elasticities and that devaluation is generally effective if domestic expenditure is controlled. [The Foreign Trade Multiplier and Econometric Models]: Haberler reviews the dynamic version of the foreign trade multiplier developed by Machlup and Metzler. This theory applies Keynesian multiplier concepts to open economies, treating imports and savings as 'leakages.' While acknowledging its value in describing the transition between equilibria, Haberler warns that its assumptions (constant prices, unlimited financing) are unrealistic. He also expresses skepticism toward large-scale econometric world-system models due to the inherent pitfalls of such complex measurements. [The Purchasing Power Parity Theory]: Haberler examines the Purchasing Power Parity (P.P.P.) theory, tracing its roots from Hume and Ricardo to Gustav Cassel. He distinguishes between the 'inflation theory' and 'balance of payments theory' of currency depreciation. While acknowledging Viner's criticisms regarding the use of price averages, Haberler argues that P.P.P. remains a valuable diagnostic tool, especially during severe inflation. He concludes that the approximate validity of P.P.P. in normal times suggests that international demand elasticities are actually quite high. [The Theory of International Trade Policy]: Haberler examines the economic justifications for departing from free trade, focusing on the 'terms of trade' and 'infant industry' arguments. He discusses how trade policy can be used to maximize national income or alter income distribution, while noting the theoretical validity of protectionism under conditions of wage rigidity, unemployment, or external economies. The section contrasts static marginal analysis with long-run dynamic theories of economic development, referencing thinkers like Mill, List, and Ohlin. [Notes to A Survey of International Trade Theory]: A comprehensive set of 70 endnotes providing bibliographic references, technical clarifications, and historical context for the preceding survey of international trade theory. Key topics include the evolution of the labor theory of value, the opportunity cost approach, community indifference curves, the Leontief paradox, and the nuances of the purchasing power parity (P.P.P.) theory. Haberler engages with the work of Viner, Samuelson, Machlup, and others to refine definitions of terms like 'absorption' and 'income terms of trade.' [Survey of Circumstances Affecting the Location of Production and International Trade]: Haberler traces the continuity of trade theory from Ricardo to the modern Heckscher-Ohlin-Samuelson framework. He critiques the over-simplification of two-factor models (labor and capital) and discusses the limitations of factor price equalization theorems in a multi-factor world. The segment also addresses 'natural resource trade,' explaining how differences in resource quality and production functions (e.g., capital-intensive vs. labor-intensive rice production) complicate standard neoclassical assumptions and help explain the Leontief paradox. [Determinants of Trade of Manufactured Goods]: Haberler examines the complex determinants of trade in manufactured goods, contrasting it with trade in raw materials. He discusses modern elaborations of Ohlin's factor proportion theory, specifically focusing on human capital, R&D, and the 'technological gap.' He details the 'product cycle' theory, where innovations originate in high-labor-cost countries like the US before shifting to mass production in lower-cost regions. The section also explores the role of increasing returns to scale and how large domestic markets provide a comparative advantage, while noting that public sector expansion in Europe has hindered the full exploitation of these scale economies. [Complexity and Empirical Testing of Trade Theories]: This segment addresses the complexity of modern trade, such as the simultaneous export and import of similar goods (e.g., ball bearings) due to specialization. Haberler reviews various empirical and statistical tests of trade theories, noting the difficulty in isolating specific factors like R&D or scale. He concludes that while precise statistical separation is difficult, the market efficiently solves these intricate allocation problems. [Where Do We Stand? Neoclassical Theory and Welfare Economics]: Haberler synthesizes the various overlapping trade models, asserting that neoclassical general equilibrium theory remains an indispensable tool despite its simplifications. He defends the normative and positive functions of competitive theory, linking it to Pareto optimality and the maximization of real national income. He acknowledges the limitations of 'universal systems' in economics, citing von Neumann and Morgenstern, but argues that the theory provides a vital 'ideal type' for evaluating real-world aberrations. [Appendix A: Alfred Marshall on Technology and the Product Cycle]: An appendix demonstrating that Alfred Marshall anticipated many modern theories regarding technology transmission and the product life cycle. Marshall described how technical knowledge moves between nations (e.g., Huguenots in England) and how industries shift to 'massive production' in different countries as they mature. It also references Daniel Defoe's early observations on English improvements upon Flemish inventions. [Appendix B: Public Sector Expansion and International Location of Production]: Haberler argues that the growth of the public sector and nationalized industries (like railways and PTT) hinders international division of labor and economic integration, particularly in Europe. He contrasts the fragmented European public utilities with the integrated private utilities in the US, suggesting that private enterprise is naturally more 'non-patriotic' and efficient in seeking optimum locations and procurement sources across political boundaries. [Notes and Bibliography for Manufactured Goods and Trade Theory]: Detailed footnotes for the preceding sections on manufactured goods and trade theory. Includes discussions on the Leontief paradox, factor intensity reversals, and critiques of Staffan Burenstam-Linder's hypothesis regarding per capita income and trade intensity. [Transfer and Price Movements: The Keynes-Ohlin Debate]: Haberler analyzes the theoretical problem of international transfers (reparations), focusing on the debate between Keynes and Ohlin. Keynes argued that a significant price decline (worsening terms of trade) is necessary for the paying country to generate a trade surplus, while Ohlin maintained that shifts in purchasing power could achieve transfer without price level changes. Haberler sides with the Thornton-Mill view that price movements are usually required but critiques the assumption that terms of trade must always turn against the payer, showing a favorable shift is theoretically possible. [Transfer and Price Movements: A Rejoinder to Bertil Ohlin]: In this rejoinder, Haberler clarifies his position on the direct vs. indirect effects of purchasing power shifts on the balance of payments. He argues that while demand shifts are central, the resulting reordering of production is driven by price shifts. He critiques the over-reliance on partial equilibrium elasticity analysis when demand curves themselves are shifting and deformed by the transfer process, referencing Pareto's general equilibrium as a conceptual but difficult-to-apply alternative. [The Market for Foreign Exchange and the Stability of the Balance of Payments]: Haberler provides a systematic theoretical analysis of the stability of the foreign exchange market. He explores how demand and supply curves for foreign currency are derived from underlying export and import curves. The section defines the conditions for stable and unstable equilibria, explaining that if the supply curve of foreign exchange is negatively inclined and less steep than the demand curve, depreciation might worsen a balance of payments deficit. [Deriving Exchange Curves from Export and Import Elasticities]: This segment details the mechanics of how currency depreciation affects prices and values of imports and exports in both domestic and foreign currencies. Haberler demonstrates that while depreciation lowers export prices in foreign currency, its effect on total export value depends on the elasticity of foreign demand. Conversely, the value of imports in domestic currency depends on home demand elasticity. The analysis assumes supply curves are positively sloped and abstracts from speculative capital movements. [Demand and Supply of Foreign Currency as Derived from Demand and Supply of Exports and Imports]: Haberler derives the demand and supply curves for foreign currency from the underlying demand and supply for exports and imports. He explains how the elasticity of demand for a currency depends on the elasticities of the domestic demand for imports and the foreign supply of those imports, noting complex relationships when demand elasticity is not unity. [Depreciation and the Balance of Payments: The Lerner Condition]: This section examines the conditions under which currency depreciation improves the balance of payments, focusing on the Lerner condition (the sum of import and export demand elasticities exceeding unity). Haberler discusses modifications for cases where supply elasticities are not infinite and where initial exports and imports are unequal, linking these to general market stability conditions. [Export Supply and Import Demand vs. Total Supply and Total Demand]: Haberler argues that import-demand and export-supply curves are derived from domestic demand and supply, making them more elastic than 'pure' domestic curves. He emphasizes the importance of the time factor in elasticity and the role of non-traded goods becoming traded as prices shift. He contrasts diversified industrial economies with specialized agricultural ones regarding their adjustment capacity. [Stability Conditions with Unequal Exports and Imports]: The author modifies the stability condition for scenarios where a country starts with a trade imbalance. He demonstrates that a larger initial import surplus can actually increase the likelihood that depreciation will improve the balance in terms of foreign currency, a point relevant to the 'dollar shortage' era. [Shifts in Domestic Demand and Supply and Monetary Policy]: Haberler discusses how depreciation can cause shifts in domestic curves through inflationary effects, the foreign trade multiplier, and wage-price spirals. He distinguishes between movements along curves and shifts of the curves themselves, arguing that for policy analysis, one must assume aggregate domestic demand is held constant to isolate the effect of the exchange rate change. [Summary of Exchange Market Stability Theory]: A summary of the preceding sections, reiterating the hierarchy of demand and supply curves (from primitive domestic schedules to aggregate currency curves). It clarifies the distinction between these money-based curves and Marshallian reciprocal demand curves in real terms. [Currency Devaluation and the Terms of Trade]: Haberler challenges the assumption that devaluation necessarily worsens a country's terms of trade. He distinguishes between the 'primary burden' of correcting a deficit (reduced domestic expenditure) and the 'secondary burden' (terms of trade loss). He provides a diagrammatic proof that if the balance of payments reacts perversely to devaluation, the terms of trade must also deteriorate, but in 'normal' cases, they may improve or worsen. [Notes and References for Chapters 7 and 8]: Footnotes and bibliographic references for the preceding theoretical discussions on foreign exchange markets and terms of trade. Includes mathematical derivations for currency elasticities and citations of key works by Machlup, Robinson, Lerner, and Metzler. [Introduction: Recent Changes in the U.S. Balance of Payments]: Haberler introduces the paradoxical shifts in the U.S. balance of payments between 1958 and 1970. He contrasts the alarming deficits of the late 1950s and late 1960s with the period of price stability under Eisenhower, noting how inflation starting in 1965 led to gold speculation and the eventual establishment of the two-tier gold market in 1968. [Reasons for the Strength of the Dollar and De Facto Inconvertibility]: The author explains the dollar's resilience despite large deficits, attributing it to the termination of the gold pool and the emergence of a de facto dollar standard. He argues that the dollar is effectively inconvertible into gold for large sums, a reality that imposes 'voluntary restraint' on foreign central banks who wish to avoid rocking the international monetary boat. He contrasts the views of Rueff, who advocates for a return to gold, and Triffin, who supports a world central bank. [Balance-of-Payments Policies: American Options and Foreign Response]: Haberler distinguishes between liquidity and adjustment problems, arguing that the latter is more fundamental. He asserts that the U.S. should prioritize domestic macro-economic objectives (employment and growth) over balance-of-payments considerations, a policy he terms 'benign neglect.' He argues that because the dollar is the world's reserve currency, the U.S. cannot unilaterally devalue, and thus the burden of adjustment should fall on surplus countries. [Reactions of Foreign Surplus Countries and the Policy of Benign Neglect]: This section analyzes the four options available to foreign surplus countries: accumulating dollars, inflating, appreciating their currency, or reducing trade barriers. Haberler defends the 'passive' U.S. stance, arguing that it is easier for a few surplus countries to appreciate than for the U.S. to devalue the dollar against all other currencies. He dismisses the efficacy of capital controls and suggests that 'benign neglect' is the most rational path for the U.S. given its unique position. [Reform of the International Monetary System and Exchange Rate Flexibility]: Haberler critiques the focus on SDRs (liquidity) over the adjustment mechanism. He explains how fixed exchange rates force U.S. inflation onto other countries and argues for greater exchange rate flexibility, such as the 'trotting peg' used by Brazil. He critiques the IMF's 1970 report on exchange rates for being too conservative and failing to address the destabilizing speculation inherent in the 'adjustable peg' system. [Summary, Concluding Remarks, and Postscript]: The author summarizes his argument for a passive U.S. balance-of-payments policy and the removal of capital controls. A postscript written after August 15, 1971, reflects on the termination of gold convertibility and the shift toward floating rates. Haberler defends the 'benign neglect' label against charges of nationalism, reiterating that it provides foreign countries with a range of rational options to maintain their own equilibrium. [Notes on International Monetary Integration and Exchange Rate Flexibility]: Haberler distinguishes between induced and spontaneous inflation, noting that persistent price rises faster than the U.S. suggest spontaneous domestic inflation. He argues that monetary integration requires deep harmonization of fiscal and wage policies, which the EEC lacks. The segment also critiques the adjustable peg system, advocating for flexible or floating rates to stop speculation, citing the 1969 German mark appreciation and Brazil's 'trotting peg' as successful examples of managing exchange rate flexibility. [The Problem of International Liquidity: Historical Perspectives]: A historical overview of international liquidity concerns from the 19th century through the interwar period. Haberler discusses the bimetallist controversy, Marshall's symmetallism, and the evolution of commodity reserve currency proposals. He analyzes the transition to the gold exchange standard and critiques the views of Rueff and Triffin regarding the causes of the Great Depression, arguing that U.S. domestic deflation was more significant than the collapse of the gold exchange standard itself. [International Reserves under Floating Exchange Rates]: Haberler examines the relevance of international liquidity theories following the breakdown of the Bretton Woods system. He critiques the 'international quantity theory' of reserves, supporting the views of Fleming and Polak that government policy behavior differs fundamentally from private utility maximization. The segment addresses the impact of OPEC reserves, the potential remonetization of gold under the Jamaica Agreement, and the role of the IMF in a world of generalized floating, concluding that the adjustment problem has superseded the liquidity problem. [Reply to Robert Triffin: Reserves and Inflation]: Haberler responds to Robert Triffin's criticisms regarding the expansion of global reserves under floating rates. He argues that reserve growth in OPEC countries and the 'snake' interventions do not invalidate the benefits of floating for industrial countries. He maintains that world inflation is rooted in national policies rather than global liquidity levels and defends the IMF's focus on conditional lending and surveillance over exchange rate manipulation. [Footnotes: International Monetary Reform and Commodity Standards]: Detailed footnotes discussing the technical differences between bimetallism and symmetallism, Marshall's 'tabular standard' (indexation), and the history of commodity reserve currency proposals by Jevons, Graham, and Hayek. It notes the shift in objectives for such systems from monetary stability to resource transfer to developing nations. [The State of the World Economy: Recession vs. Depression]: Haberler analyzes the global economic downturn of the early 1980s, arguing it is a recession caused by necessary disinflation rather than a 1930s-style depression. He critiques the pessimism of Kissinger, Thurow, and Kenen, asserting that the primary obstacle to recovery is wage rigidity. He argues that a reduction in real wages is necessary to shift income to profits and stimulate investment, rejecting 'structuralist' fears that technology (robots) will permanently displace labor. [Oil Shocks and the International Debt Problem]: This segment evaluates the impact of OPEC oil shocks and the international debt crisis on the global economy. Haberler argues that the oil shocks were not the primary cause of inflation but rather aggravated existing trends. Regarding debt, he asserts that a collapse of the banking system is unlikely because modern monetary authorities will not allow the money supply to contract as it did in the 1930s, provided depositors are protected. [The Evolution of the Dollar and the Rise of Floating Rates]: A historical account of the U.S. dollar's transition from the 'dollar shortage' era to the breakdown of Bretton Woods. Haberler describes the inflationary pressures of the 1960s, the suspension of gold convertibility in 1971, and the eventual move to floating in 1973. He details the dollar's weakness in the late 1970s and the subsequent policy shift under Paul Volcker in 1979 that initiated disinflation and led to the dollar's dramatic appreciation in the early 1980s. [Critiques of Floating and the Return of Gold Standard Rules]: Haberler examines contemporary criticisms of floating exchange rates and the resurgence of gold standard principles in modern monetary theory. He discusses McKinnon's 'world money hypothesis' and the IMF's use of Domestic Credit Expansion (DCE) as modern iterations of the gold standard's adjustment rules. He also reviews Otmar Emminger's views on 'judicious interventions' to correct market overshooting and Fred Bergsten's concerns regarding the 'overvalued' dollar. [The Mechanics of Exchange Rate Intervention]: An analysis of the effectiveness of official interventions in foreign exchange markets. Haberler distinguishes between sterilized and nonsterilized interventions, arguing that sterilized actions are largely ineffective because they do not change the money supply. He critiques the European Monetary System (EMS) as an economic failure and discusses the 1983 'coordinated interventions,' concluding that such gestures are unlikely to significantly alter exchange rate trends unless accompanied by fundamental monetary policy changes. [Concluding Remarks on Floating and Market Disorders]: Haberler summarizes the case for floating exchange rates as a 'second best' system necessitated by the lack of policy coordination and wage flexibility required for fixed rates. He argues that floating protects countries from monetary shocks but not real shocks. He cautions against frequent interventions, noting the extreme difficulty of diagnosing 'overshooting' or determining an 'equilibrium' rate in the complex modern asset market. [Incomes Policy: Guidelines vs. Market Restoration]: Haberler analyzes the debate over incomes policy as a tool to fight inflation. He distinguishes between 'Incomes Policy One' (generalized guidelines and freezes) and 'Incomes Policy Two' (measures to restore competition and curb union monopoly power). He argues that guidelines are counterproductive as they distort relative wages, and instead advocates for structural reforms—such as modifying minimum wage laws and anti-trust actions—to address the root cause of wage-push inflation. [Demand-Pull versus Cost-Push Inflation]: Haberler distinguishes between demand-pull and cost-push inflation, arguing that both are essentially monetary phenomena requiring expansion of the money supply or its velocity. He explores the 'dilemma' faced by monetary authorities when powerful trade unions force up wages: either permit inflation or accept unemployment. While some economists like Milton Friedman argue union power is exaggerated, Haberler contends that downward wage rigidity and market power create persistent upward pressure on prices. [Labour Unions and Industrial Monopolies]: The author contrasts the behavior of industrial monopolies with labor unions, arguing that while business monopolies have a 'one-shot' effect on price levels, unions exert a continuous upward pressure by seeking annual wage increases. Haberler asserts that unions often succeed in pushing money wages beyond competitive equilibrium, which leads to a choice between inflation or unemployment. He also argues that unions likely have a negative long-run effect on the real income of labor as a whole due to resource misallocation and induced inflation. [The Phillips Curve: A Critical Analysis]: A detailed critique of the Phillips Curve, which postulates a stable relationship between unemployment and the rate of wage/price changes. Haberler reviews the 'equilibrium' view championed by Milton Friedman, which argues that the trade-off is only temporary due to the eventual erosion of 'money illusion'. He concludes that while a short-run trade-off may exist during periods of mild inflation, there is no stable long-run relationship as expectations and market structures shift over time. [Wage Guideposts and Incomes Policy]: Haberler evaluates 'Incomes Policy One' (generalized guideposts) and 'Incomes Policy Two' (structural measures to increase competition). He argues that wage guideposts based on productivity targets are theoretically sensible but practically impossible to implement without distorting relative wages or devolving into inefficient general price controls. He emphasizes that the root cause of wage-push inflation—excessive union power—must be addressed directly rather than through synthetic substitutes like 'jawboning'. [Restraining Union Power and the British Scene]: This section discusses specific measures to reduce inflationary wage pressure, such as withdrawing union legal immunities, repealing minimum wage laws, and eliminating welfare subsidies for strikers. Haberler then analyzes the British economic situation in the early 1970s, referencing Frank Paish and James Meade. He concludes that while inflation is a monetary phenomenon, the structural aggressiveness of unions creates a permanent challenge that monetary policy alone can only solve at the cost of high unemployment. [Postscript 1985: Reflections on Macroeconomic Shifts]: In a 1985 postscript, Haberler reflects on the evolution of macroeconomic theory since his 1971 essay. He critiques the extreme version of 'rational expectations' for ignoring wage rigidity and dismisses 'Incomes Policy I' (controls) in favor of 'Incomes Policy II' (supply-oriented policies like deregulation). He distinguishes his supply-oriented approach from 'supply-side economics', which he views as overoptimistic regarding tax cuts, and reaffirms that monetary-fiscal demand management remains a necessary complement to structural reforms. [Footnotes on Money Illusion, Phillips Curve, and Labor Unions]: A comprehensive collection of footnotes (23-80) discussing the theoretical underpinnings of inflation, the Phillips curve, and the role of labor unions. It critiques Keynesian 'money illusion', examines the shift from demand-pull to wage-push inflation theories, and reviews various incomes policy proposals and legal immunities of unions. Key thinkers mentioned include Hayek, Friedman, Tobin, and Arthur Burns. [A New Look at Inflation: Historical Perspectives and the Smithsonian Agreement]: This section introduces the New Economic Policy of 1971 and the subsequent Smithsonian Agreement, analyzing the deterioration of the U.S. balance of payments. It provides a historical perspective on the dollar's post-WWII supremacy, the transition from the dollar-gold exchange standard to a pure dollar standard, and the impact of Vietnam War financing on U.S. inflation and trade deficits. [Currency Crises and the Shift to Floating Exchange Rates (1967-1973)]: An analysis of the series of currency crises between 1967 and 1973 that led to the collapse of the adjustable peg system. Haberler details the speculative pressures on the dollar, the closing of the gold pool, and the eventual move toward managed floating by major economies like Germany and Japan. He argues that the basic defect of the system was the malfunctioning adjustment mechanism. [The Inflation-Transmission Multiplier and U.S. Monetary Hegemony]: Haberler explores how U.S. inflation is transmitted to other countries through the 'inflation-transmission multiplier'. He explains the asymmetrical relationship where the U.S. sets the pace for world inflation due to its domestic policy focus ('benign neglect'). The section highlights the divergence between CPI and WPI in high-productivity countries like Japan and Germany compared to the U.S. [The Future of the International Monetary System and the Role of Floating]: Haberler argues that floating exchange rates are the only effective way to manage parity changes without triggering disruptive capital flows. He critiques the 'adjustable peg' and the use of capital controls, noting that speculation often shifts to commodities when financial markets are restricted. He concludes that curbing U.S. inflation is central to stabilizing the global system, regardless of whether SDRs replace the dollar. [Postscript: The 1973 Dollar Crisis and the Failure of Price Controls]: A postscript written in July 1973 analyzing the continued depreciation of the dollar and the failure of the Nixon administration's price freezes. Haberler identifies the Watergate affair and excessive monetary growth as factors undermining confidence. He argues that the 1973 inflation was demand-driven rather than cost-push, rendering controls ineffective, and introduces the upcoming discussion on the OPEC oil price shock. [The Domestic Impact of Oil Price Increases]: Haberler analyzes the domestic economic impact of the 1973-1974 oil price hike, specifically focusing on the United States. He argues that in a perfectly competitive economy with flexible wages, the oil levy would only require a minor, once-for-all reduction in real income. However, because money wages are rigid downward, the necessary reduction in real wages is typically achieved through inflation. He concludes that the oil price rise was not the primary cause of the two-digit inflation or the recession, but rather a 'last straw' acting upon an already inflationary boom and a rigid economic structure. [International Aspects of the Oil Crisis and Petrodollar Recycling]: This section addresses the international monetary implications of OPEC's price increases. Haberler refutes contemporary fears that the international system could not handle the transfer of funds. He compares the situation to the German reparations of the 1920s, arguing that the oil transfer is actually less problematic because OPEC countries have a high propensity to import or invest their surpluses back into industrial economies. He advocates for managed floating exchange rates and argues that the market, particularly the Euro-dollar market, has successfully 'recycled' petrodollars without the need for elaborate official redistribution schemes. [Notes to the Oil Price Impact and International Aspects]: Detailed footnotes providing statistical data from the OECD and IMF regarding GNP impacts of oil prices. It includes theoretical citations regarding downward wage inflexibility and the 'New Cambridge School' debate on import restrictions. It also touches upon the historical debate between Keynes and Ohlin regarding international transfers. [Stagflation: Theoretical and Policy Problems]: Haberler examines the phenomenon of stagflation—the coexistence of high inflation and high unemployment. He argues that stagflation is impossible in a perfectly competitive economy and is caused by institutional rigidities, specifically labor union power and government regulations that make wages and prices sticky. He critiques modern 'microfoundations' literature for ignoring the role of unions and 'real wage resistance.' He concludes that monetary restraint is necessary but insufficient; it must be paired with structural reforms to restore market competition to avoid a cycle of 'stop-and-go' policies and eventual regimentation. [Notes to Stagflation and Structural Reform]: Footnotes discussing the severity of postwar recessions, the growth of the public sector in Britain and Italy, and the negative effects of minimum wage laws and the Davis-Bacon Act. It includes references to the 'New Deal' era cost-push inflation and critiques of reinterpreting Keynesian involuntary unemployment as merely an information problem. [The World Economy, Money, and the Great Depression 1919–1939]: Opening title for a section or essay focusing on the economic and monetary history of the world between 1919 and 1939, specifically addressing the Great Depression. [Introduction: The World Economy, Money, and the Great Depression 1919–1939]: Haberler introduces an essay describing the restoration and subsequent collapse of the gold standard during the 1920s and 1930s. He outlines the structure of the work, which includes a chronicle of events and an analysis of various explanations for the severity of the Great Depression, emphasizing the influence of leading economies like the United States. [A Chronicle of Events: From the Stabilization of the Mark to the Outbreak of the Great Depression: 1923–1929]: This section details the rapid physical reconstruction of Europe after WWI and the slower, more difficult restoration of the gold standard. Haberler discusses the stabilization of various European currencies, the shift from a gold specie to a gold exchange standard, and the inherent flaws in the system, such as the misalignment of parities (overvalued pound vs. undervalued franc) and the growing downward rigidity of money wages which made deflationary adjustments painful. [The Great Depression: United States and Great Britain]: Haberler analyzes the onset and progression of the Great Depression in the US and UK. He argues the US depression was largely homemade and exacerbated by a massive contraction of the money supply and bank failures. He describes the UK's departure from gold in 1931, the formation of the sterling area, and how the US New Deal policies, including dollar devaluation and wage-boosting measures, influenced the recovery and subsequent 1937-1938 recession. [The Great Depression: Germany, Japan, and France]: This section compares the depression experiences of Germany, Japan, and France. Germany utilized exchange controls and stable money wages to achieve a rapid recovery under Hitler, contrasting with the US experience. Japan used devaluation and military spending. France, leading the 'gold bloc', suffered from an overvalued currency until the 1936 Tripartite Agreement allowed for a face-saving devaluation, though internal social reforms led to rapid price rises. [The International Monetary Order and the Legacy of the Depression]: Haberler reflects on how the Great Depression permanently altered the international monetary system, ending the 'sanctity' of fixed exchange rates. He criticizes the 'adjustable peg' system for encouraging speculation and argues that the increase in international liquidity was achieved through a 'perverse' and painful process of deflation and devaluation. He suggests that extensive floating would have been a better remedy for currency realignment than the sequential devaluations that occurred. [Some Explanations: Maladjustments and the Depression]: Haberler evaluates various theories explaining the Great Depression. He critiques the 'maladjustment' view (League of Nations) and the 'neo-Austrian' theory (Hayek/Robbins), arguing that real structural distortions were 'swamped' by massive monetary deflation. He also dismisses the 'secular stagnation' hypothesis (Hansen) in light of post-WWII prosperity, emphasizing that the depression's severity was due to institutional failures and policy mistakes rather than inherent capitalist contradictions. [Reparations and War Debts]: Haberler discusses the economic and political impact of WWI reparations and war debts. While politically disastrous and a trigger for German deflationary policy, he argues their economic weight was relatively small compared to GNP. He refutes 'transfer pessimism,' asserting that reparations could have been managed if not for the global depression and the resulting explosion of protectionism. [The Monetary Factor and Competitive Depreciation]: Haberler emphasizes the 'overwhelming importance' of monetary factors in the Great Depression, specifically the collapse of the US banking system and the Fed's failure to prevent money supply contraction. He redefines 'competitive depreciation' as deliberate undervaluation for export advantage, arguing it was a product of rigid exchange rates and the 'adjustable peg' system rather than floating. He concludes that the lack of international policy coordination made the cycle of devaluations inevitable. [Concluding Remarks on the Great Depression]: Haberler concludes his analysis of the Great Depression by examining its political repercussions, such as the rise of Hitler and the enhanced reputation of the Soviet Union. He argues that the depression's severity was due to 'adventitious' monetary circumstances rather than inherent flaws in capitalism. He discusses the evolution of economic policy, the role of the IMF and GATT in postwar growth, and the shift from the depression-era problem of deflation to the modern challenge of stagflation, noting that while Keynesian prescriptions worked for the former, they struggle with the latter. [Notes to Selected Essays]: Comprehensive endnotes providing citations and supplementary commentary on the preceding text. Topics include the history of the Japanese yen, the British return to gold in 1925, the 'Great Contraction' as defined by Friedman and Schwartz, the Schachtian system in Germany, and the intellectual debates between Keynes, Ohlin, and the Austrian school regarding capital structure and maladjustments. [Notes to Selected Essays (Continued)]: Continuation of the endnotes, focusing on the technical aspects of the 1930s crisis. It covers the failure of the American banking system, the impact of the Smoot-Hawley tariff, the 'gold bloc' devaluations, and the specific economic conditions of the 1974-1975 recession compared to the Great Depression. It also clarifies the use of the term 'Keynesian prescriptions' in relation to classical economic theory. [The Great Depression of the 1930s—Can It Happen Again?]: Haberler compares the Great Depression of the 1930s with the post-WWII economic era to assess the likelihood of a recurrence. He rejects non-monetary explanations like secular stagnation or inherent capitalist collapse, instead identifying massive monetary deflation in the U.S. as the primary cause of the 1930s disaster. He contrasts this with the modern problem of stagflation, arguing that while a deflationary collapse is now unlikely due to policy awareness, the combination of cost-push inflation and wage rigidity creates a different, more complex policy dilemma. He concludes that managed floating exchange rates have helped the modern world avoid the 'beggar-thy-neighbor' traps of the 1930s. [Concluding Remarks on the Great Depression and Inflation]: Haberler concludes his analysis by arguing that the Great Depression was not a failure of capitalism but a result of catastrophic monetary policy mistakes. He contrasts the deflationary depression of the 1930s with modern chronic inflation and stagflation, warning that government overreaction to unemployment leads to a vicious circle of regulation, bureaucracy, and declining productivity that threatens democracy. [Notes to The World Economy, Money and the Great Depression]: A comprehensive set of 44 endnotes providing citations and extended commentary on the preceding essay. Key discussions include the Hayek-Robbins theory of monetary over-investment, the role of the Federal Reserve in the 1930s, the German economic miracle under Ludwig Erhard, and Keynes's eventual reconversion to liberalism and rejection of 'Schachtian' protectionist practices. [The World Economy, Macroeconomic Theory and Policy—Sixty Years of Profound Change: Overview]: Haberler begins a new essay reviewing sixty years of economic change. He identifies World War I as the end of the liberal epoch of free trade and migration. He describes the fragile recovery of the 1920s, characterized by higher tariffs and hyper-inflation in Europe, leading up to the 1929 crash. [The Great Depression and the Post-World War II Surprise]: This section analyzes the devastating impact of the Great Depression, including its role in Hitler's rise to power and the surge of Marxist thought. Haberler then discusses the 'Great Surprise' of the post-WWII era: a period of unprecedented growth facilitated by the Marshall Plan, GATT, and 'classical medicine' (sound finance) in countries like Germany, Japan, and Italy. [The Keynesian Revolution and the Monetarist Counterrevolution]: Haberler examines the intellectual shift from Keynesian 'fiscalism' to the monetarist rediscovery of money. He critiques the Keynesian theory of secular stagnation and argues that the severity of the Great Depression was primarily due to the Federal Reserve allowing a 30 percent contraction of the money supply. He suggests a synthesis where fiscal policy is useful to stop a deflationary spiral once it has gathered momentum. [The Present Economic Malaise and the Limits of Monetarism]: Haberler addresses the 1970s economic malaise, arguing that inflation is not a permanent cure for unemployment. He explores the 'limits of monetarism,' asserting that while monetary restraint is necessary, it must be supported by fiscal discipline and structural reforms to address market inflexibilities like labor union monopoly power and government-induced rigidities which cause stagflation. [Policy Conclusions and Future Scenarios]: The author outlines two future scenarios: a 'dismal pattern' of stop-and-go policies leading to repressed inflation and regimented socialism, or a firm policy of monetary-fiscal restraint supported by structural reforms (deregulation, curbing union power). He emphasizes the importance of policy credibility and the 'announcement effect' in breaking inflationary expectations. [Notes to Sixty Years of Profound Change]: Endnotes for the essay 'Sixty Years of Profound Change'. Includes references to John Hicks, T.W. Hutchison's critique of Keynesians, and the 'rediscovery of money' by Friedman and Schwartz. It clarifies that Keynes himself was often more concerned with inflation than his later disciples. [Monetary Policy and the Great Depression: Debates and Evidence]: Haberler examines the debate over the causes of the Great Depression, contrasting the Friedman-Schwartz-Cagan thesis of exogenous monetary contraction with Nicholas Kaldor's Keynesian skepticism. He highlights Roy Harrod's endorsement of the monetary explanation and critiques Kaldor's reliance on the liquidity trap and Canadian data, arguing that Canada's experience actually supports the monetary view when accounting for fixed exchange rates and banking stability. [Historical Notes on the Gold Standard, Trade, and Inflationary Expectations]: A collection of numbered notes (11-26) addressing various economic phenomena: the collapse of the gold standard, the decline of world trade, and the neglect of inflationary expectations in Keynesian policy (citing James Tobin). Haberler also discusses the instability of the Phillips curve, the limitations of supply-side economics, the historical growth of wage and price rigidity (citing Frank Knight), and the theoretical distinction between voluntary and involuntary unemployment, critiquing the rational expectations school's interpretation of labor supply shocks. [Global Economic Challenges: North-South Dialogue and Hyper-inflation]: Notes 27-32 address global political economy and inflation. Haberler critiques the Brandt Commission's alarmist view of the North-South income gap, arguing that international tensions are primarily East-West. He discusses the failure of direct wage and price controls (Incomes Policy I) versus liberalization (Incomes Policy II). Finally, he compares the difficulty of stopping chronic modern inflation with the abrupt end of historical hyper-inflations, noting that hyper-inflation creates unique conditions (debt wipeout, high velocity) that facilitate stabilization. [Economic Development and the Terms of Trade: A Theoretical Discussion]: Haberler begins a major essay on the relationship between the terms of trade and economic development. He distinguishes between commodity terms of trade (Px/Pm) and factorial terms of trade, arguing that a deterioration in the former does not necessarily imply a loss of welfare if productivity has increased. He critiques the 'income terms of trade' as a welfare indicator, suggesting it is better used as a measure of the capacity to import, particularly for Latin American economies. [Critique of the Secular Deterioration Thesis]: Haberler critiques the theory that terms of trade secularly deteriorate for primary producers. He identifies three flaws in the statistical evidence (largely based on UK data): the failure to account for quality improvements in manufactured goods, the exclusion of falling transportation costs (the Wright effect), and the lack of representativeness of UK indices for other industrial nations. He also contrasts the Engel's Law argument with the classical fear of diminishing returns, concluding that neither provides a reliable basis for long-run forecasting. [Cyclical Instability and Policy Responses in Underdeveloped Countries]: This section examines the short-run cyclical fluctuations of the terms of trade. Haberler acknowledges that primary producers often suffer in depressions but warns against overgeneralizing from the 1930s. He critiques international commodity agreements and buffer stocks as unworkable, advising underdeveloped countries to instead 'learn to live' with instability through sound financial management, counter-cyclical accumulation of reserves, and participation in international organizations like the IMF and GATT. [Integration and Growth of the World Economy in Historical Perspective]: Haberler provides a historical overview of economic integration, defining it as the equalization of commodity and factor prices. He identifies three waves: the internal integration of nation-states (e.g., UK, France, US Constitution, German Zollverein), the 19th-century free trade movement, and the post-WWII era of global growth. He argues that national integration was a prerequisite for world-wide growth and notes that the post-1948 wave has been more beneficial than modern regional schemes. [World-Wide Integration through Freer Trade]: Haberler examines the second wave of global economic integration during the mid-nineteenth century, spearheaded by Great Britain's move toward free trade. He discusses the impact of the Cobden-Chevalier Treaty and the liberalization of shipping and colonial trade. Despite a return to higher tariffs in the late 1870s due to agricultural competition and depressions, world trade continued to grow until World War I, supported by the gold standard, international clearing mechanisms, and the flow of capital and labor. [Disintegration of the World Economy, 1914–45]: This section analyzes the period of global economic disintegration between 1914 and 1945. Haberler argues that the severity of the Great Depression was not due to inherent capitalist contradictions or secular stagnation, but rather to catastrophic policy failures and the destruction of the money supply. He critiques the 'beggar-my-neighbor' devaluations and the timing of New Deal reforms, suggesting that the economic collapse was a singular historical catastrophe rather than an inevitable cyclical event. [The Growth of World Trade since the War: The Case of the Industrial Countries]: Haberler discusses the third wave of integration following World War II, noting that world trade has grown faster than production for the first time in a century. He defends the performance of the American economy against stagnation theories, attributing recent slacks to balance of payments deficits rather than structural failures. He emphasizes that the removal of direct controls and the return to the price mechanism were essential for the rapid recovery of Europe and Japan. [The Growth of World Trade and the Less Developed Countries]: Haberler addresses the participation of less developed countries (LDCs) in the postwar trade expansion. He rejects Marxist and Myrdalian theories of 'increasing misery,' arguing that LDCs have benefited from industrial growth. While acknowledging a deterioration in the terms of trade since 1950, he demonstrates that it was not catastrophic compared to the 1930s and that the 'capacity to import' has generally increased. He concludes that a stagnant world market is not the primary handicap for LDCs, pointing instead to internal policies and population pressures. [Outlook for the Future of World Trade]: Haberler discusses the future of world trade, identifying two primary conditions for continued growth: the maintenance of high employment in industrial countries and further trade liberalization. He expresses concern over regional integration schemes like the EEC and LAFTA, which he views as potentially protectionist, and emphasizes that internal wage and price discipline is more critical than international liquidity issues. [Notes to 'Integration and Growth of the World Economy']: A comprehensive set of endnotes providing citations and supplementary commentary on topics such as the Great Depression, the trade-GNP ratio, the terms of trade for developing countries, and the impact of falling transport costs on global integration. It includes references to thinkers like Keynes, Schumpeter, Myrdal, and Kindleberger. [Economic Development and International Trade: First Lecture]: In this first lecture delivered at the National Bank of Egypt, Haberler defines economic development as the growth of per capita real income and argues that international trade is a primary engine for this growth. He defends the classical theory of comparative cost against 'static' criticisms, introducing the 'productivity' theory of trade which highlights indirect benefits such as the importation of capital goods and technical know-how. [Notes on International Trade and Economic Development]: A collection of numbered notes (14-42) addressing various aspects of international trade, innovation, and economic development. Haberler discusses the lack of industrial innovation from post-revolutionary Russia, critiques Gunnar Myrdal's views on international inequality, and examines the 'terms of trade' debate involving Prebisch and Singer. He also touches upon the concept of disguised unemployment, the 'vicious circle of poverty', and the migration of skilled labor between regions and countries. [Critical Notes on Schumpeter’s Theory of Money]: Haberler provides a rigorous critique of Joseph Schumpeter's 'fundamental equation of the theory of money'. He argues that Schumpeter's equation is a tautology rather than a causal relationship because the two sides of the equation are merely different arithmetic expressions of the same quantity (money spent vs. money received). The segment explores the definitions of income, money stock, and the velocity of circulation, specifically critiquing the limitation of the equation to goods of the first order. [The Subjective and Objective Value of Money]: Haberler examines the conceptual difficulties in defining the 'objective exchange value' of money. He argues that the global objective value of money is a 'sham problem' and a linguistic symbol for complex price combinations rather than a real-world entity. He critiques the 'social value' theories of Wieser and B.M. Anderson, contrasting them with the individualistic marginal utility approach of the Austrian school. He concludes that economic analysis only requires the concepts of subjective value and price. [Postscript: The Micro-Foundations of Price Index Theory]: A postscript summarizing Haberler's later work on index numbers and the price level. He explains the economic interpretation of Laspeyres and Paasche formulas, defining the 'true' change in the price level based on individual household satisfaction (indifference). He discusses the practical application of the Consumer Price Index (CPI) for monetary policy, the distinction between monetary and 'real' causes of price changes, and historical debates like the bimetallist controversy. [Footnotes to Previous Essay and Introduction to the Multiplier]: Concluding footnotes regarding price index formulas and the objective value of money, followed by the introduction of a methodological criticism of Keynes's multiplier theory. [Mr. Keynes’ Theory of the “Multiplier”: A Methodological Criticism]: Haberler provides a rigorous methodological critique of Keynes's multiplier, arguing that Keynes treats a relationship defined by identity as if it were a causal or empirical law. He distinguishes between the 'formal' propensity to consume (a mathematical identity) and the 'psychological' propensity (an empirical observation), arguing that Keynes conflates the two to reach precarious conclusions about the magnitude of secondary employment effects. [Notes on the Multiplier and Introduction to Schumpeter's Theory of Interest]: Footnotes for the multiplier essay followed by an analysis of Joseph Schumpeter's theory of interest. Haberler distinguishes between Schumpeter's extreme version (zero interest in a stationary state) and a milder version involving dynamic entrepreneurial mechanisms. [Schumpeter's Theory of Interest: Analysis and Critique]: An evaluation of Schumpeter's interest theory, focusing on the 'extreme' claim that interest would be zero in a stationary state. Haberler uses Fisherian diagrams to analyze the roles of time preference and marginal productivity, ultimately siding with the 'optimists' (Knightians) who believe investment opportunities exist even without new inventions, while acknowledging Schumpeter's unique focus on the role of the innovator and inflationary credit in the capitalist process. [The Pigou Effect and Underemployment Equilibrium]: Haberler defends the Pigou effect (wealth-saving relation) as a theoretical refutation of the Keynesian underemployment equilibrium. He argues that while the Pigou effect may not be a practical policy tool for ending cycles, it invalidates the secular stagnation thesis by showing that falling prices increase the real value of wealth, thereby stimulating expenditure. He also critiques Metzler's view on how open-market operations affect the equilibrium interest rate. [Notes on Wage Flexibility and Secular Stagnation]: A collection of technical footnotes addressing the relationship between relative prices and aggregate demand, the secular stagnation thesis, and the role of wage flexibility in cyclical unemployment. It also touches on the wealth-saving relation and Schumpeterian dynamic changes. [After Ten Years [1946]: An Appraisal of the Keynesian Revolution]: Written on the tenth anniversary of 'The General Theory', Haberler evaluates the scientific content and lasting impact of the Keynesian revolution. He argues that while Keynes provided a valuable aggregative framework and emphasized income effects, the core theoretical claims—such as underemployment equilibrium—depend heavily on the assumption of rigid wages. Haberler contends that once wage flexibility is introduced, the system reverts to classical conclusions, and he suggests that Say's Law had already been abandoned by neoclassical economists in its literal sense long before Keynes. [Sixteen Years Later [1962]: Retrospective on the General Theory]: A 1962 update to Haberler's critique of Keynesianism, incorporating the 'Pigou effect' (wealth-saving relation) as a definitive theoretical rebuttal to the possibility of a permanent underemployment equilibrium. Haberler reviews the impact of Keynes on postwar policy, noting that many 'economic miracles' in Europe and Japan were achieved by non-Keynesian or conservative statesmen. He concludes that while Keynes was a genius who refined the 'armoury of economic analysis', his work was an evolution of existing ideas rather than a total break from the past. [Notes and References for the Keynesian Appraisals]: Technical endnotes for the preceding essays on Keynes, providing citations for early econometric models (Frisch, Tinbergen), discussions on the elasticity of liquidity preference, and the theoretical distinction between the Keynes effect and the Pigou effect. [Psychological Factors in Business Cycles and the Post-Keynesian Consensus]: Haberler examines the role of 'errors of optimism and pessimism' in business cycles, linking Pigou's psychological theories to Keynes's 'marginal efficiency of capital'. He critiques the Rational Expectations school for neglecting institutional rigidities like wage stickiness, arguing that while agents are rational, they do not all possess the same model of the economy. He outlines a 'Post-Keynesian Consensus' that accepts the importance of money in the short run but rejects a permanent Phillips curve trade-off in the long run. Finally, he discusses the 1973-74 oil shock as a case where monetary expansion was a justifiable response to downward wage rigidity. [Concluding Remarks on Rational Expectations and Post-Keynesian Consensus]: Haberler concludes his analysis by evaluating how rational expectations theory fits into the post-Keynesian consensus. He argues that while the theory has sharpened economic concepts, its radical claim that rational behavior eliminates the gap between short-run and long-run equilibrium is unacceptable. He highlights William Fellner's 'credibility hypothesis' as a more realistic alternative that accounts for institutional rigidities and the necessity of government persistence in anti-inflationary policy. [Notes and References]: A comprehensive set of endnotes providing citations and supplementary commentary for the preceding essay. Topics include the history of business cycle theory, critiques of Keynesianism, the development of monetarism, and the origins of rational expectations. It features detailed references to works by Pigou, Keynes, Friedman, Machlup, and Fisher, as well as contemporary critiques by Arrow and Tobin.
