第14章 真实经济周期

引言

The quarter-century after 1945 produced the highest sustained growth rates in the history of industrial economies, and the sharpest divergence between economies that captured those rates and economies that did not. Western Europe and Japan converged toward the American productivity frontier at speeds that would have looked implausible in 1945. Latin American economies grew solidly under import-substitution programs that began to crack by the late 1960s. Newly independent African states grew at rates comparable to their Asian peers in the first decade after flag independence and then stagnated. The label “golden age” is accurate for some economies and misleading for others; the chapter walks both threads and asks why the same period produced such different outcomes.

14.1 卢卡斯批判

Between 1950 and 1973, French GDP per capita grew at roughly 5 percent per year. West German GDP per capita grew at 6 percent. Italian growth ran above 5 percent. The United States, the productivity frontier these economies were chasing, grew at about 2.5 percent. For two decades, the gap between Western Europe and the American benchmark closed measurably each year. The French historian Jean Fourastié named the period the Trente Glorieuses (the thirty glorious years), and the German label Wirtschaftswunder, the economic miracle, captured the same phenomenon from the West German side. The labels are not retrospective embellishment. The growth rates ran for long enough to remake the standard of living in a single working lifetime, and at levels no already-industrialized economy had previously sustained.

The pattern was convergence: economies behind the productivity frontier growing faster than the frontier economy, narrowing the per-capita gap. Solow growth theory predicted exactly this. Diminishing returns to capital make investment more productive where capital is scarce, so war-devastated economies with intact human capital should grow faster than the undamaged American economy. (For the formal mechanism, see economics ch. 13.) The prediction held. The figure shows the trajectories.

Data: Maddison Project (Bolt & van Zanden 2020); Penn World Table as cross-check. Ghana’s national-accounts data for 1957–1965 are thinner than the other series.

The American line sits at the top, climbing from a postwar peak through the 1960s. France, West Germany, and Japan rise steeply from low postwar bases toward it. Brazil grows moderately, then plateaus. India and Ghana stay close to flat. The convergence and the divergence are visible on the same chart, and the rest of the chapter walks the institutional reasons for both. For a fuller spatial view of the period (all roughly 180 economies on an animated choropleth, with country annotations and year-events), the GDP map carries the 1945–1971 frame.

The Western European convergence ran on a combination of enabling conditions, not on any single instrument. The exchange-rate stability provided by Bretton Woods removed the currency-volatility risk that had paralyzed cross-border investment in the interwar period. The Marshall Plan delivered roughly $13 billion in capital injection between 1948 and 1951, modest as a share of European GDP but decisive at the margin for relieving the dollar shortage that constrained imports of American capital goods. Successive GATT rounds liberalized trade through staged tariff reductions, opening the export markets that sustained European industry. The mixed-economy consensus inside each national economy combined Keynesian demand management, an expanding welfare state, and selective industrial policy under broadly social-democratic governments. And large-scale labor migration (southern Italians moving to northern Italian and West German factories, Algerians to France, Turks to West Germany under the Gastarbeiter programs) supplied the manpower that the convergence growth rates required. The institutional architecture built at Bretton Woods (covered in ch. 13) operated as the precondition for these enabling conditions; this chapter narrates the consequences. The free-trade dimension of the postwar order, and the long debate it set off, is the subject of a separate walkthrough.

The mixed-economy consensus was not invented in 1945. It was inherited. The 1930s policy experiments that ch. 12 covered (New Deal demand management in the United States, Stockholm-school countercyclical fiscal policy in Sweden, even Schacht’s reflation under emergency conditions in Germany) had broken the orthodoxy of balanced budgets and gold-standard discipline. By 1945, the technical case that governments could and should manage aggregate demand was widely accepted across non-communist Europe. What the postwar consensus added was political durability: a settlement between organized labor, employers, and the state in which growth, full employment, and an expanding social wage were jointly delivered. Beveridge’s 1942 report in Britain, the West German Soziale Marktwirtschaft, and the French Commissariat général du Plan were national variants of the same broad arrangement.

The labor-supply dimension is easy to underweight. France absorbed roughly 1.5 million workers from Algeria, Portugal, Spain, and Italy during the 1950s and 1960s. West Germany’s Gastarbeiter programs brought in about 2.6 million guest workers by 1973, with Turks the largest group. Italy itself ran an internal version of the same dynamic: roughly 9 million people moved from the agricultural south to the industrial north between 1955 and 1971. The migration was not incidental to the growth; it was a precondition. Sustained 5 to 6 percent growth in industrial output requires industrial workers, and the postwar European labor force could not have supplied them through natural increase alone.

Output growth on this scale required output markets, and the European Coal and Steel Community of 1951 followed by the Treaty of Rome and the European Economic Community of 1957 supplied the institutional architecture that converted national industrial output into a continental market. The customs union among the original six (France, West Germany, Italy, Belgium, Netherlands, Luxembourg) phased internal tariffs out across the 1960s and operated as the regional analogue of GATT’s global tariff cuts. Intra-European trade volumes more than tripled across the decade. The growth and the integration reinforced each other: tariff-free access expanded the market that domestic producers could serve, and the resulting scale economies fed back into productivity gains that sustained the convergence.

The Western European story was the broad-front version of the golden age. The same quarter-century produced a growth phenomenon in Japan that outpaced even Western Europe.

14.2 基本RBC模型

In 1945, Japan was a defeated and occupied country with bombed-out cities, a destroyed merchant marine, and per-capita output that had fallen to roughly the level of 1910. By 1968, Japan had passed West Germany to become the world’s second-largest economy after the United States. The 1960s growth rate ran at 9 to 10 percent per year, higher than any major economy had ever sustained over a comparable period. Japan’s line on the figure is the steepest one. The institutional package behind it was distinct enough that the East Asian economies of the 1960s would explicitly study it as a template.

The conditions for the takeoff were laid during the American occupation. Land reform under General MacArthur’s authority redistributed agricultural land from absentee landlords to tenant cultivators between 1947 and 1950, eliminating the rural landlord class as a political and economic obstacle to industrialization. Roughly 5 million tenants became owner-cultivators. The reform broke the political base of pre-war agrarian conservatism and converted the countryside into a mass of small commercial farmers with an interest in industrial-sector goods. The Korean War (1950–1953) provided the demand catalyst. American procurement orders for trucks, steel, textiles, and services during the war and its immediate aftermath ran at roughly $2.4 billion between 1950 and 1953, equivalent to a substantial fraction of Japanese GDP at the time, and concentrated in the industries that would lead the postwar growth.

The institutional mechanism that turned the postwar conditions into sustained growth was the developmental-state package built around the Ministry of International Trade and Industry (MITI), the keiretsu business groups, the main banks, and a savings-investment nexus that channeled household deposits into industrial lending. MITI did not directly own enterprises. It coordinated. Administrative guidance, the Japanese practice in which a ministry issues non-binding directives that nonetheless shape firm behavior because firms depend on the ministry for licenses, foreign-exchange allocations, technology import approvals, and tax treatment, gave MITI leverage that no equivalent American agency possessed. The keiretsu were horizontally and vertically linked groups of firms (Mitsubishi, Mitsui, Sumitomo, Fuyo, Sanwa, Dai-Ichi Kangyo), each anchored by a main bank that held equity in the group’s firms, coordinated their financing, and sat on their boards. The structure inherited the prewar zaibatsu form (which ch. 8 covered) without the family-holding-company apex that the occupation had dissolved.

The clearest way to see how the package worked is to walk it sector by sector. Steel was the first target. MITI identified steel as a strategic industry in 1950 and orchestrated its build-out across the decade that followed. The Japan Development Bank and the main banks supplied directed credit at preferential rates, with MITI signing off on the loan composition. MITI brokered technology licenses with American and European steelmakers (Armco, U.S. Steel, the Austrian VOEST consortium that had pioneered the basic-oxygen furnace) at terms that captured the technology without committing Japanese firms to long-term royalty drains. Tariffs and import quotas protected the domestic market while Japanese plants scaled up to internationally competitive size. Once cost-competitiveness was achieved, by the late 1950s for basic steel, MITI managed the export push, coordinating which firms entered which foreign markets to avoid mutually destructive price competition. By the mid-1960s, Japanese steel was the world’s lowest-cost producer of high-quality output.

The same pattern ran through the automobile industry in the 1960s. Toyota and Nissan were small producers in 1955; by 1971 they were major exporters. MITI restricted foreign automotive investment in Japan during the scaling period (Ford and GM were kept out) while permitting selective technology licensing (Toyota learned from a brief technical relationship with Ford and a longer one with European producers). The Japan Development Bank financed plant expansion. The home market grew rapidly under tariff protection, building the volume that allowed Japanese producers to ride down the cost curve. By the late 1960s, Toyota and Nissan were exporting to the United States. MITI then orchestrated the Honda–Yamaha–Suzuki entries into motorcycles and the build-out of consumer electronics through Sony, Matsushita, Toshiba, and others, repeating the sector-by-sector sequence: protect, scale, license technology, export.

The package required savings to fund the directed investment, and it had them. Japanese household savings rates ran at 15 to 20 percent of disposable income through the 1960s. The postal savings system, a state-run deposit network reaching every village and neighborhood, collected those savings at low cost and channeled them through the Fiscal Investment and Loan Program into the Japan Development Bank, public corporations, and infrastructure investment. The main banks did the same on the private side, recycling household deposits into long-term industrial credit at preferential rates. The volume was the point: Japanese fixed investment ran at roughly 30 to 35 percent of GDP through the 1960s, more than double the American rate.

The sector-by-sector sequencing (textiles and light manufacturing carrying the early 1950s, then steel and shipbuilding through the late 1950s and early 1960s, then automobiles and electronics from the mid-1960s) was the structural transformation that the growth numbers measured. By 1971, Japanese shipbuilding was the world’s largest, Japanese steel was internationally competitive, Japanese cars were entering American driveways, and Japanese consumer electronics were beginning the displacement of American producers that would intensify in the next decade. Japan’s line on the GDP map carries the trajectory in fuller detail.

Chalmers Johnson’s MITI and the Japanese Miracle (1982) gave the model its analytical name. Johnson called the Japanese state a developmental state: a state that takes industrialization as an explicit strategic objective and deploys credit allocation, market protection, technology policy, and administrative coordination to achieve it. The form is distinct from the American regulatory state, which constrains private firms within a market framework, and from the Soviet planner state, which substitutes for private firms entirely. Three other economies were studying the Japanese template in the 1960s, adapting it to different starting conditions.

14.3 校准

By the late 1960s, three other authoritarian states on the Pacific rim (South Korea under Park Chung-hee, Taiwan under the Kuomintang, and Singapore under Lee Kuan Yew’s People’s Action Party) were each building developmental-state institutions on Japanese lines. Each was resource-poor. Each had chosen export-oriented industrialization. Each had a distinct historical starting point. The growth payoff would come in the 1970s and 1980s and is the subject of ch. 17; what this section walks is the institutional setup the 1960s built. The setup is analytically separable from the payoff, and the chapter takes them in that order.

The institutional heritage runs back further than 1960. Witte’s late-imperial Russia and Meiji Japan were the first instances of explicit state-directed industrialization, and ch. 8 covered them as the original developmental-state archetype. Park Chung-hee had served as an officer in the Manchukuo Imperial Army during Japanese occupation and had observed the Meiji-derived industrial system directly; the South Korean Economic Planning Board built in 1961 borrowed the Japanese template explicitly. The 1960s East Asian states were heirs, not inventors.

The five dimensions on which the three economies are most usefully compared run as follows. Take them as a structured walk, with the three economies in parallel under each heading.

Political precondition. All three states were authoritarian, and all three regimes treated economic development as the regime’s primary source of legitimacy. South Korea’s military government under Park, installed by coup in 1961, concentrated authority in the executive. Taiwan under the Kuomintang governed under martial law from 1949 onward, the regime’s legitimacy resting increasingly on its delivery of economic development on the island. Singapore under Lee Kuan Yew was nominally democratic but operated as a one-party state in which the People’s Action Party tolerated little organized opposition. The shared feature was the political insulation of economic policy from short-cycle electoral pressure: the autonomy that allowed industrial planners to back specific firms and sectors without rent-seeking churn.

Initial inequality and land reform. South Korea and Taiwan both completed land reforms in the late 1940s and early 1950s that broke the landlord class and produced low rural inequality. The Korean reform, accelerated by wartime disruption, distributed land to roughly 1.5 million tenant households; the Taiwanese reform, with American advisory support from the Joint Commission on Rural Reconstruction, transferred land in three stages between 1949 and 1953. Singapore had no agriculture worth speaking of, but its public housing program through the Housing and Development Board substituted for land reform as the asset-distribution mechanism.

Credit channeling. All three states channeled credit to favored sectors at preferential rates. South Korea nationalized the commercial banks in 1961; the Korean Development Bank and the Export-Import Bank of Korea ran the directed-credit programs that financed the chaebol (Hyundai, Samsung, Lucky-Goldstar, Daewoo) through their initial scaling. Taiwan ran a more decentralized system in which state-owned banks supplied long-term credit to a mixed structure of state enterprises, large private firms, and a dense small-and-medium-enterprise sector. Singapore’s Development Bank, founded in 1968, channeled state savings (collected through the compulsory Central Provident Fund) into industrial investment, supplemented by an aggressive policy of attracting multinational corporations to Singapore’s industrial estates.

Education investment. All three states invested heavily in technical education. Korean primary-school enrollment was already above 90 percent in 1960, and the regime expanded secondary and technical education through the decade. Taiwan’s indicators were similar. Singapore built a vocational and polytechnic system designed to supply the skill mix that the multinationals it was courting required. The pattern was the same: invest in human capital ahead of demand, then court industries that would demand it.

Integration strategy. All three pivoted from import-substitution to export-led industrialization in the early 1960s, but through different instruments. South Korea’s shift began with Park’s 1964 currency devaluation and was institutionalized through annual export targets that the Economic Planning Board negotiated with each major chaebol; firms that hit their targets retained credit access, firms that missed lost it. Taiwan worked through export-processing zones (Kaohsiung in 1966 was the first), offering tariff-free access to imported inputs for firms that exported their output. Singapore went furthest, courting multinational corporations as the principal vehicle of industrial growth in exchange for export-platform investment.

The shared pattern is the analytical point. The three economies built mutually reinforcing institutional packages: authoritarian political insulation, low initial inequality, directed credit, human-capital investment, and export discipline. The package operated as a system, not as a list of policies. Removing any single element would have left the others working at lower efficiency. This is why the variation across the three economies (different political histories, different sectoral mixes, different roles for state versus private firms, different reliance on multinationals) matters less than the shared structure. The developmental state was a package, and the question of why some states could assemble the package while others could not is the question the chapter’s synthesis returns to.

The package was also contested. Two intellectual positions on what made the East Asian growth happen took shape across the 1980s and early 1990s, and they remain the framing positions today. Each is worth taking at strongest form.

The first position, advanced most fully by Robert Wade in Governing the Market (1990) and Alice Amsden in Asia’s Next Giant (1989), holds that the East Asian states actively governed their markets and that the governance was the cause of the growth. Wade documented the Taiwanese state’s detailed sectoral interventions (the targeted credit, the technology-acquisition negotiations, the public-enterprise leadership in heavy industry) and argued that the Taiwanese economy looked nothing like a textbook market because it was not run as one. Amsden made the parallel case for South Korea: the state did not merely set the rules and let firms compete; it picked sectors, picked firms, set performance targets, rewarded firms that hit them and punished firms that did not. Her phrase “getting the prices wrong” inverted the orthodox slogan: South Korean prices were systematically distorted by the state to favor exports, capital accumulation, and structural transformation, and the distortions were what produced the growth. The structural transformation from textiles to steel to shipbuilding to electronics did not happen as a spontaneous market response to changing comparative advantage. It happened because the state directed it.

The second position, voiced most influentially by Anne Krueger and consolidated in the World Bank’s The East Asian Miracle report (1993), holds that the East Asian growth happened despite the state interventions rather than because of them. Krueger’s 1974 paper on rent-seeking had argued that protected industries generate large welfare losses through the resources firms expend lobbying for protection rather than producing output, and the framework underwrote a generation of skepticism about industrial policy. The World Bank report acknowledged that East Asian states had intervened heavily but argued that the interventions that worked were the ones consistent with market-friendly fundamentals: stable macroeconomic management, openness to international trade and technology, investment in human capital, and broadly competitive markets. The interventions that picked sectors and firms were either neutralized by the export discipline (firms that failed to meet export targets lost their subsidies, simulating the discipline of competition) or were positively harmful (Korea’s heavy and chemical industry drive of the 1970s, in the report’s reading). The growth would have happened with the fundamentals alone; the directed credit and the picking of winners were noise on top of the signal.

The debate over what made these developmental states work will return in the chapter’s synthesis. First, the other side of the postwar story: the economies that chose a different path.

14.4 Decolonization and Import-Substitution Industrialization

What newly independent states took over from colonial rule was not an economy ready for independence but a set of structural constraints. Ch. 10 catalogued the structures: low-revenue extraction-optimized colonial states, commodity-export dependence calibrated to metropolitan demand, port-and-mine railway networks oriented toward shipping out raw materials rather than integrating internal markets, minimal investment in mass education and public health, and a thin layer of indigenous administrative and technical capacity. The decolonizing states of the 1950s and 1960s inherited these structures wholesale. The strategy choices they faced were constrained from the start by what they had to work with.

The political moment that gave decolonization a coordinated voice was the Bandung Conference of April 1955, where 29 African and Asian states (Nehru’s India, Sukarno’s Indonesia, Nasser’s Egypt, Zhou Enlai’s China among them) assembled to coordinate a non-aligned position between the American and Soviet blocs and to articulate a developmental program for the post-colonial world. The Non-Aligned Movement that emerged from Bandung and its 1961 Belgrade follow-up was as much an economic project as a political one. The shared diagnosis was that colonial economic structures had to be deliberately overturned, and that the world economic order, tilted in favor of industrialized exporters of manufactures and against commodity-dependent developing economies, had to be reformed.

The strategy menu had three options. The first was the planned-economy model on the Soviet pattern: state ownership of major industry, central planning of investment and prices, agricultural collectivization. Ch. 15 walks the model in detail; here it is enough to note that several decolonizing states (notably under Nyerere in Tanzania and Nkrumah in Ghana) adopted partial versions of the planned-economy approach during the 1960s. The second was import-substitution industrialization (ISI): a state-led industrial-policy package that protected domestic infant industries with tariffs and import quotas, supplied directed credit to favored sectors, and used state-owned enterprises to build heavy-industry foundations. The third was open-economy integration on Hong Kong lines, which almost no decolonizing state of this period chose. ISI was the dominant choice across Latin America (where it had begun in the 1930s under depression conditions) and across the larger newly independent Asian and African economies.

The intellectual justification for ISI came together in the work of Raúl Prebisch at the United Nations Economic Commission for Latin America (CEPAL) and Hans Singer at the United Nations Department of Economic Affairs. Their independently developed 1950 papers established what became known as the Prebisch–Singer thesis: the relative price of primary commodities in terms of manufactured goods, the terms of trade for commodity exporters, tends to deteriorate over the long run. The argument runs through several mechanisms: income elasticity of demand is higher for manufactures than for primary commodities, so as world income grows, demand for manufactures grows faster; productivity gains in manufacturing are captured by industrial-country wages and profits while productivity gains in commodity production are competed away through lower prices; commodity markets are more competitive than manufacturing markets, so the gains from technical progress accrue to industrial-country producers and consumers rather than to commodity producers. The policy implication: economies that remain commodity exporters fall behind permanently, so the route to development is to industrialize even if the initial cost in foregone consumption is high. The formal model and the empirical literature it generated sit in economics ch. 20; for present purposes, what matters is that the thesis provided ISI with a coherent intellectual case, and that the terms-of-trade mechanism it identified operated empirically across the period the chapter covers.

Brazil under Juscelino Kubitschek (1956–1961) ran the most ambitious Latin American ISI program. Kubitschek’s Plano de Metas, the Plan of Targets, promised “fifty years in five” and concentrated state investment on energy, transport, basic industries, and the new federal capital at Brasilia. The state development bank (BNDE) channeled credit to favored sectors. The automobile industry was the showpiece: Kubitschek invited Volkswagen, Ford, General Motors, and Mercedes-Benz to set up Brazilian plants behind tariff walls that excluded finished imports, with local-content requirements ratcheting up year by year so that domestic supplier industries had to develop alongside the assembly plants. By 1961, Brazil had a functioning automotive sector. GDP grew at roughly 7 percent per year through Kubitschek’s term, and the industrial share of output rose sharply. The growth was real, but the political economy that financed it (deficit spending, credit creation, tolerated inflation) was building strain. The early 1960s saw inflation accelerate, the balance of payments come under pressure as imported capital goods outran export earnings, and political conflict intensify. The 1964 military coup was triggered by political crisis but framed by the economic stresses the ISI growth model had built.

Mexico ran a parallel ISI strategy with a different macroeconomic profile. The period of desarrollo estabilizador (stabilizing development) from the mid-1950s through the late 1960s combined ISI behind tariff walls with an unusually disciplined macroeconomic stance: fixed exchange rate, balanced budgets, low inflation, conservative monetary policy. The arrangement was institutionalized through tight coordination between the Bank of Mexico and the finance ministry under successive technocratic finance ministers, supported politically by the long-standing PRI hegemony. Mexican GDP per capita grew at roughly 6 percent per year, inflation stayed below 5 percent for much of the period, and the peso held its parity with the dollar through the late 1960s. The model worked while two conditions held: the domestic market was large enough to absorb expanding industrial output, and the agricultural sector generated foreign exchange to pay for capital-goods imports. Both conditions began to weaken by the late 1960s. Income inequality widened, restricting the domestic market’s growth. Agricultural productivity stagnated. The fiscal arithmetic that desarrollo estabilizador required became harder to sustain. The strain that would surface as full crisis in the 1970s was building beneath the apparent stability.

Brazil and Mexico together demonstrate that ISI was not a single strategy but a family. The Brazilian variant was inflationary, ambitious, and politically volatile. The Mexican variant was disciplined, gradualist, and politically stable. Both produced genuine industrial growth. Both accumulated structural weaknesses that the model itself could not resolve.

The structural weaknesses ISI accumulated were systematic. Tariff protection, set high enough to keep imports out, also kept domestic firms from facing competitive pressure to drive down costs. Infant industries did not graduate. The political coalition behind the protection (firm owners, organized labor in protected sectors, state-bank creditors) had no interest in withdrawing it. State-owned enterprises ran fiscal losses that strained government budgets, particularly as their employment expanded for political rather than productive reasons. And the foreign-exchange constraint kept tightening: industrializing through ISI required imported machinery, intermediate goods, and technology, all paid for with export earnings from the very commodity sectors that ISI was supposed to move the economy away from. The structural weaknesses that would crack in the 1970s were building through the 1960s, and ch. 16 picks up the unraveling.

India ran its own large ISI program through this period under the Planning Commission and successive Five-Year Plans, with state ownership of heavy industry alongside a private-sector capacity ceiling enforced by licensing. India is visible on the figure as one of the slowly growing lines; the detailed planning history belongs to economics ch. 20. The same decade that saw ISI-driven growth in Latin America saw independence sweep across sub-Saharan Africa, with a different inheritance and a different trajectory.

14.5 African Independence and Its Early Economic Record

In the early 1960s, newly independent African economies were growing at rates comparable to their Asian peers. Commodity prices were high. New governments were investing in roads, schools, hospitals, and the first generation of industrial projects. The leadership was young, educated, and politically committed to building economies that would deliver development. Ghana under Kwame Nkrumah, Tanzania under Julius Nyerere, Kenya under Jomo Kenyatta, Sénégal under Léopold Sédar Senghor: the cohort of independence-era leaders set out a developmental agenda as ambitious as anything the East Asian tigers were assembling. The early growth numbers showed the agenda was working. Then, across the second half of the 1960s and into the early 1970s, the growth slowed and in some cases stopped.

The structural inheritance was the binding constraint. The borders the new states had to govern were the colonial borders, drawn at Berlin in 1884–1885 with no reference to language, economic geography, or pre-colonial polities. The administrative apparatus was thin: the British colonial service in Ghana on the eve of independence consisted of a few thousand officials, and the indigenous senior cadre was numbered in the dozens. Technical capacity was thinner still: Ghana had under a hundred indigenous engineers in 1957. The economic base was narrow and externally oriented: cocoa accounted for roughly two-thirds of Ghana’s export earnings, copper for over 80 percent of Zambia’s, groundnuts for the bulk of Senegal’s. The infrastructure ran from interior production zones to coastal ports, with limited connectivity between neighboring African economies. The financial system was dominated by branches of metropolitan banks whose lending priorities were set in London, Paris, or Brussels. The independence ceremony transferred political sovereignty over these structures; it did not transform them.

Ghana’s trajectory traces the pattern in concentrated form. Ghana achieved independence in March 1957 as the first sub-Saharan African colony to do so, and Nkrumah’s Convention People’s Party government took office with high cocoa-export earnings funding an ambitious program. The Volta River Project, a hydroelectric dam at Akosombo and an associated aluminum smelter at Tema, was the centerpiece, designed to provide cheap electricity to power industrialization and to demonstrate that an African state could mount infrastructure on a scale the colonial administration had not. The project was completed in 1965. Alongside it, the state expanded education aggressively (free primary schooling, a major university build-out), invested in import-substituting consumer-goods factories, and built up a state-owned trading sector to displace the foreign trading houses that had dominated the colonial economy. Ghanaian GDP per capita rose through the late 1950s and into the early 1960s.

The break came through the cocoa-price collapse. World cocoa prices peaked in the mid-1950s and trended downward through the early 1960s; the bottom fell out in 1965, when the price dropped to less than half the 1954 peak. Ghana was a cocoa monoculture in export terms, and the price collapse cut export earnings, foreign-exchange reserves, and government revenue simultaneously. The Cocoa Marketing Board, which had taxed cocoa-farmer earnings to fund the development program, had been depleting farmer reserves for years; when the world price fell, there was no buffer. Industrial projects requiring imported inputs ran out of foreign exchange. Inflation accelerated. The political settlement Nkrumah had built came apart, and the military coup of February 1966 ended his government. Successive Ghanaian regimes through the late 1960s and early 1970s presided over an economy that had stopped growing and was beginning the long stagnation the next chapter picks up. The Prebisch–Singer thesis’s central mechanism, commodity terms-of-trade volatility undermining commodity-dependent development, operated on Ghana exactly as the thesis predicted.

Other African states tried different strategies and reached convergent outcomes. Tanzania under Nyerere launched the Ujamaa program in 1967, organized around the Arusha Declaration’s commitment to socialist self-reliance. The program forcibly resettled scattered rural households into nucleated villages designed to support cooperative agriculture, communal services, and a coordinated rural development push. The state nationalized banks and major commercial enterprises. The agricultural-productivity payoff did not materialize. Cooperative farming proved less productive than the dispersed peasant agriculture it replaced, and Tanzania’s economic record through the 1970s would be poor by Asian comparison, though more equitable in distribution than several alternatives. Kenya took a different path. Sessional Paper No. 10 of 1965, “African Socialism and Its Application to Planning in Kenya,” committed the Kenyatta government to a mixed-economy strategy: private property, foreign investment welcomed, smallholder agriculture supported, but with an active state role in infrastructure and education and explicit Africanization of the commercial sector. Kenyan growth through the 1960s outperformed Tanzania’s, but ran into structural limits as inequality widened and political conflict over land and access to opportunity intensified.

The pattern across these cases is what C9 names: real growth in the first decade of independence, then stagnation. Ghana stops growing by the late 1960s. Tanzania does not break out. Kenya grows but cannot reach the rates that the East Asian comparators were posting. The causes were structural and reinforcing: commodity dependence exposing each economy to terms-of-trade shocks, thin bureaucratic capacity limiting state effectiveness, political fragility as new ruling coalitions struggled to manage the distributional pressures that growth and stagnation alike generated, and a global trading order that offered limited entry routes for African manufactures into the protected industrial markets of the global north. Ghana on the figure is the flat line against the converging Western and Japanese trajectories. The visual is the chapter’s sharpest single image of divergence.

The early-1970s pattern is where this chapter stops on Africa. The full unraveling (debt crises, structural adjustment programs, the lost decade of the 1980s) belongs to ch. 16, which picks up African economic history at the point this section leaves it. The population dynamics of the developing world in this period make even these growth numbers ambiguous.

14.6 The Demographic Transition Begins

Between 1950 and 1970, the developing world’s population grew faster than at any point in human history. Asia grew from roughly 1.4 billion to 2.1 billion. Latin America grew from 167 million to 285 million. Africa grew from 229 million to 366 million. The annual growth rates (roughly 1.9 percent for Asia, 2.7 percent for Latin America, and 2.5 percent for Africa across the period) had no historical precedent at this scale. The numbers come from the United Nations World Population Prospects estimates and the World Bank’s historical World Development Indicators; the orders of magnitude are robust even where the country-level estimates are uncertain.

The driver was the demographic transition: the historical sequence in which mortality declines first and fertility declines later, with a multi-generation lag in between during which population grows rapidly. In the developing world after 1945, mortality decline was concentrated and fast. DDT spraying programs cut malaria mortality across tropical Asia, Africa, and Latin America from the late 1940s onward. Antibiotics, available globally after the war, cut deaths from bacterial infection that had been major killers a generation earlier. Vaccination programs against smallpox, tuberculosis, and the childhood killers expanded under WHO and national public-health auspices. Clean-water and sanitation investment, where governments could fund it, cut infant and child mortality further. Life expectancy at birth in many developing countries rose by 15 to 25 years between 1950 and 1970, a gain that took European populations a century or more to achieve.

Fertility decline did not follow immediately. Norms about family size are slow to adjust to mortality conditions, and the institutional changes that drive fertility down (female education, female labor-force participation, urbanization, formal-sector employment, contraceptive availability) take time to spread. Total fertility rates in much of the developing world remained at five, six, or seven children per woman through the 1950s and 1960s, even as infant mortality dropped. The lag between the two transitions produced the population boom: more babies surviving while women continued to have many of them. By the late 1960s, fertility decline was beginning in some countries (Singapore, South Korea, Hong Kong, Mauritius were early); in much of Africa, the fertility decline would not begin in earnest for another generation.

The Malthusian alarm followed the numbers. Paul Ehrlich’s The Population Bomb (1968) predicted mass famine within the next decade as population growth outran the food supply. The Club of Rome’s The Limits to Growth (1972), modeling population, resource use, and pollution together, projected systemic constraints on continued growth that would force a crisis within a century. Both works captured a real concern about whether the demographic-transition trajectory was compatible with the planetary carrying capacity. The actual outcome diverged from the most apocalyptic predictions: Green Revolution agricultural productivity gains (Borlaug’s wheat varieties, IRRI’s rice varieties) pushed food production ahead of population growth across most of the developing world through the 1970s and 1980s, and the fertility transition began to take hold in much of Asia and Latin America. Whether the Malthusian frame was wrong or merely deferred remains contested; the demographic transition is incomplete in much of sub-Saharan Africa, and the carbon-cycle constraint that the Club of Rome flagged has displaced the food constraint as the binding one.

Two implications follow for reading the chapter’s growth numbers. The first is interpretive. A country growing aggregate GDP at 4 percent per year while its population grows at 3 percent is barely growing per capita; a country growing aggregate GDP at 6 percent while its population grows at 1 percent is growing per capita at roughly 5 percent. The figure’s GDP-per-capita trajectories already net out the demographic effect, but the headline aggregate-GDP numbers from the period (often cited admiringly for African and Latin American growth in the early 1960s) are misleading without the demographic correction. African per-capita growth across the 1960s was lower than the headline aggregate numbers suggested because population was growing fast; East Asian per-capita growth was higher than the regional headlines suggested for the opposite reason in some country-years. The second implication is forward-looking. The window during which mortality has fallen and fertility has also fallen, so that the working-age share of population is unusually high relative to dependents, is the demographic dividend. The dividend opens for two or three decades and closes as the working-age population itself ages. The East Asian economies entered their dividend window in the late 1960s and 1970s, just as their developmental-state institutions were ready to convert it into growth; the dividend forms one of the explanations for why ch. 17’s East Asian growth miracles happened where they did. The demographic dividend that the transition would eventually deliver is part of the explanation for why the next period’s growth miracles happened where they did.

14.7 Why the Golden Age Was Golden for Some

The same quarter-century produced 5 to 6 percent growth in Western Europe, 9 to 10 percent in Japan, moderate growth in Latin America with structural fragility underneath, and early disappointment in much of Africa. The question is why.

Three variables, taken together, organize the answer.

The first is initial conditions. Western Europe and Japan in 1945 were physically devastated but institutionally intact: their pre-war industrial base, technical workforce, scientific capacity, legal systems, and administrative apparatus survived the war even where their cities did not. They were behind the American productivity frontier by accident of war damage rather than by structural absence of the prerequisites for catch-up. The Solow convergence prediction described their situation accurately. The decolonizing world faced the inverse condition. Newly independent states in Africa and large parts of Asia had inherited extractive colonial economies built around commodity export, port-and-mine infrastructure, thin indigenous administrative capacity, and minimal investment in human capital. Latin America, independent since the early nineteenth century, sat between: industrialized partially under interwar ISI and the postwar continuation, but with persistent inequality, weak fiscal capacity, and commodity-export dependence as binding constraints. Initial conditions did not determine outcomes, but they set the gradient against which institutional choices had to push.

The second variable is the institutional quality of the state. Developmental states (Japan, then Korea, Taiwan, Singapore) combined three properties that the comparison cases lacked. They had capacity: a competent technical bureaucracy able to gather information, design policy, and administer programs. They had autonomy: insulation from short-cycle distributional pressure that allowed them to back specific firms and sectors over the multi-year horizons that industrial transformation required. And they had discipline: the willingness to withdraw support from firms and projects that were failing, rather than letting failed bets become permanent fiscal obligations. ISI states had the ambition of state-led industrialization but lacked one or more of the three conditions: Brazil and Mexico had real bureaucratic capacity but limited autonomy from rent-seeking coalitions and weak discipline (failed firms were recapitalized rather than wound down). Newly independent African states had political will but minimal bureaucratic capacity, and the state-society relationship was too fragile to sustain the discipline that withdrawing support from failed projects required. The variation across cases is explained by which states could assemble the package, not by whether they tried to use the state at all.

The third variable is integration strategy. Export orientation imposed an external discipline that ISI lacked. Firms competing in export markets had to meet international price and quality standards continuously; firms protected from import competition did not. The East Asian developmental states converted their state coordination into export performance, and the export-discipline mechanism kept the state interventions efficient by punishing firms that failed to meet international standards. ISI economies oriented their state interventions toward the domestic market, where competitive discipline was systematically muted by the protection that ISI required. Commodity-dependent African economies remained externally oriented but only as primary-product exporters, fully exposed to terms-of-trade volatility.

The three variables explain the variation across cases together. Initial conditions without institutional capacity produced the African pattern. Institutional ambition without state capacity produced the ISI pattern. Capacity, autonomy, discipline, and export discipline together produced the East Asian developmental-state pattern. The Western European golden age combined favorable initial conditions, mixed-economy institutions of high quality, and an integration strategy (the Common Market and GATT) that supplied external discipline. Japan combined unfavorable initial conditions with developmental-state institutions of unusual quality and an export-orientation strategy that compounded both.

The developmental-state debate’s resolution falls out of this. Wade and Amsden are closer to the evidence on the mechanism: states directed investment, the direction mattered, and the structural transformation from textiles through steel and shipbuilding to electronics did not happen as a spontaneous market response to changing comparative advantage. The Krueger and World Bank position correctly identifies that bad industrial policy is worse than no industrial policy and that protected rent-seeking destroys value at scale, but the East Asian cases show that the choice is not between intervention and non-intervention. It is between high-capacity intervention with discipline and low-capacity intervention without it. The binding variable is which states, doing what, under what conditions. Peter Evans’s Embedded Autonomy (1995) named the conjunction of capacity, autonomy, and discipline as the property that distinguished the East Asian developmental states from their developing-country comparators; Atul Kohli’s State-Directed Development (2004) extended the analysis comparatively. State quality, not state presence versus absence, is the variable the evidence asks the analyst to track. The convergence question this evidence feeds is the modern face of the debate.

By 1971, the golden age was intact but showing strain. The American balance-of-payments deficit, driven by Vietnam-era fiscal expansion alongside the rising competitiveness of European and Japanese exports, was eroding the gold stock that backed the Bretton Woods dollar standard. ISI in Latin America was running into the foreign-exchange constraint and the fiscal-burden constraint that its critics had warned about a decade earlier. African stagnation was hardening from a transitory cocoa shock into a structural pattern. The Bretton Woods exchange-rate system that had underwritten the European convergence was under pressure that would break it within months of the chapter’s end-date. The chapter ends at the cusp, not the break.

The developmental-state foundations built in the 1960s would produce their growth payoff in the next period; the East Asian story this chapter set up runs through the next two decades and is the subject of ch. 17. The strain in the golden-age order (the American deficit, the ISI cracking, the African stagnation hardening) is what the next chapter picks up. The next chapter picks up where this one ends, at the moment when the golden age broke.
