Market-led against interventionist strategies; export-led industrialisation and the Lewis model; FDI, aid, debt relief, microfinance and mobile money, tourism, Fairtrade, buffer stocks; the World Bank, IMF and NGOs. Through Bangladesh’s garment industry.
Bangladesh joined the UN’s least developed country list in 1975. Half a century later its ready-made garment industry employs about four million people and exported $38.7bn in the year to June 2026, more than four fifths of all its exports, with the EU taking around 44% under duty-free “Everything But Arms” access. Female employment, literacy and life expectancy rose with it; extreme poverty fell steeply.
Graduation from LDC status, scheduled for 24 November 2026, would start the loss of those trade preferences: UNCTAD estimated export losses of up to $17.5bn, and firms warned of tariffs of 6% or more in India, Japan and China. In February 2026 the new government asked for more time; the UN Committee for Development Policy agreed in June, and on 29 October 2026 the General Assembly extended the preparatory period, for Bangladesh and Nepal, to 24 November 2029.
Which strategies move a country from poverty to development, and what are their costs?

Market-oriented strategies trust prices and openness: trade liberalisation (cutting tariffs so resources follow comparative advantage); promoting FDI (capital, technology and market access from multinationals); removing subsidies and floating the exchange rate; privatisation and deregulation; microfinance (small loans to households with no collateral). These were the “Washington consensus” of the 1990s.
Interventionist strategies use the state: import substitution industrialisation behind tariffs; protectionism for infant industries; managed exchange rates to keep exports cheap; public investment in infrastructure and human capital (schools, clinics); buffer stocks to stabilise commodity prices; joint ventures that oblige foreign firms to share technology. East Asia mixed the two: export promotion with heavy state direction.
Other strategies. Industrialisation through the Lewis model: surplus rural labour moves to factories at a constant wage, profits are reinvested, the modern sector grows. Tourism. Developing primary industries rather than abandoning them. Fairtrade premiums for producers. Aid: bilateral or multilateral, tied or untied, humanitarian or developmental. Debt relief, as under the HIPC initiative. International institutions: the World Bank lends for projects, the IMF for balance-of-payments crises with conditions, NGOs work on the ground. The financial sector matters throughout: banks, mobile money such as M-Pesa, and microfinance turn small savings into investment.
Bangladesh was due to leave the UN’s list of least developed countries on 24 November 2026. On 29 October the General Assembly gave it until 2029.
The country asked for the delay. Graduation is a mark of success: Bangladesh had met all three criteria, the only LDC ever to do so. Yet its government fought to postpone it.
Why would a country want to stay on a list of the poorest?
Bangladesh’s strategy for fifty years has been export-led industrialisation: four million workers, mostly women, moved from farms into garment factories selling duty-free to Europe. The strategy worked well enough to end LDC status, and depends on preferences that graduation removes. Every strategy in this lesson comes with a trade-off like that.
The Lewis model, Bangladesh’s story in a diagram. Surplus labour on farms means factories can hire at a constant wage of $10, just above what the farm provides. Firms hire until MRP1 equals the wage: 40,000 workers. Everything between MRP and the wage is profit, 400 in total. In the model, those profits are reinvested; that is what makes the next step.
Check: In the Lewis model, the supply of labour to the modern sector is horizontal because:
Removing a worker from an overcrowded farm loses little output, so the factory need only offer slightly more than the farm share to attract unlimited labour.
The engine. Reinvested profits raise capital per worker; MRP shifts right to MRP2, then MRP3. Employment rises to 60,000, then 80,000, at the same wage, and profits grow each round. Workers leave subsistence farming for factory pay; output, exports and tax revenue rise. This is export-led industrialisation: Korea, China and Bangladesh in turn, each starting with textiles.
Check: Factory owners reinvest their profits in machines, raising each worker’s productivity. On the diagram:
With the wage pinned by surplus labour, all the gain from investment goes to profit and employment, which funds the next round. That is the engine.
The turning point. At 90,000 the surplus is gone; the supply curve turns up and wages rise. China hit it around 2010 and its garment jobs went to Bangladesh and Vietnam. The strategy’s limits: it depends on open export markets (hence the fight over LDC status), on reinvestment rather than capital flight, on wages staying low for a generation, and on a transition to higher-value industry before the cheap-labour advantage ends.
Teacher tip: The LDC deferment is the Lewis model meeting trade policy: the whole engine runs on duty-free access to the EU, so tariffs of 6 to 12% threaten the profit triangle that funds reinvestment. Ask students which other strategies Bangladesh needs before 2029.
Check: At the Lewis turning point:
China reached it around 2010: wages rose fast, and low-cost garment work moved to Bangladesh and Vietnam. Bangladesh will reach it too.
Market-led. Trade liberalisation forces firms to compete at world prices; FDI brings capital and know-how; microfinance and mobile money let the poor save and borrow: M-Pesa reached most Kenyan adults. The record: countries that opened up grew faster than those that substituted imports behind tariffs. The caveats: openness exposes infant industries and the poor to shocks, and the gains need institutions to spread them.
Check: The strongest argument for market-oriented strategies over import substitution is:
Import substitution produced small, high-cost industries serving home markets; export promotion forced firms to compete at world prices.
The rest of the toolkit. Aid fills the savings gap but can breed dependency and corruption; it works best targeted. Debt relief (HIPC cancelled over $100bn) freed budgets for health and education. Tourism earns foreign currency but leaks to foreign owners. Fairtrade raises some incomes without changing the market. Buffer stocks stabilise prices until they run out of money. The IMF lends in crises with conditions that are themselves contested.
Check: Which criticism of aid is most often made?
Aid works best for specific goals, vaccination, disaster relief, infrastructure, and worst as general budget support to weak states. Debt relief under HIPC freed resources where it was tied to spending on health and schools.
The wage is shown rising to $20 when MRP shifts. While surplus labour remains, the supply curve is flat: the wage stays at $10 and all of the gain goes to employment (60,000) and profit. Wages rise only at the turning point.
Evaluate the view that export-led industrialisation is the most effective strategy for growth and development in low-income countries.
Export-led industrialisation moves labour from low-productivity agriculture into manufacturing that sells to world markets. The Lewis model explains why it can transform an economy: with surplus rural labour, factories hire at a constant wage just above subsistence, earn profits equal to the gap between marginal revenue product and the wage, and reinvest them, shifting the demand for labour right and raising employment round after round until the surplus is exhausted. Korea, Taiwan and China followed this path, each starting with textiles, and Bangladesh has followed it since the 1980s: garment exports reached $38.7bn in 2025/26, four million people, mostly women, work in the industry, and extreme poverty, literacy and life expectancy all improved enough for the country to meet every criterion for leaving least-developed status.
The strategy’s strengths are the discipline of world markets, which import substitution lacks, the foreign exchange it earns, the learning it transmits and the tax base it builds. Its dependencies are equally clear. It needs open markets: Bangladesh’s engine runs on duty-free access to the EU, which is why its government sought and on 29 October 2026 obtained a three-year deferral of graduation rather than face tariffs that UNCTAD estimated could cost up to $17.5bn of exports. It needs profits to be reinvested at home rather than sent abroad, wages to stay low for a generation, and a plan for the turning point, when surplus labour ends and the cheap-labour advantage passes to the next country, as it passed from China to Bangladesh after 2010.
**However,** it is not the only route and not available to all. Landlocked countries with small populations cannot easily become garment exporters; Botswana developed through diamonds and good governance, Costa Rica through tourism, education and electronics, Rwanda through state-led services. Market-oriented reforms, FDI, microfinance and mobile money raised incomes in places where no factory sector emerged; aid and debt relief under HIPC freed budgets for health and schooling where they were tied to results. And industrialisation has costs the aggregate figures hide: dangerous factories, as at Rana Plaza, environmental damage and a concentration of exports in one sector exposed to one market.
On balance export-led industrialisation has the best record of any strategy for large, labour-abundant countries with access to open markets, and the Lewis model explains why. But its success rests on things that are not strategies at all: a capable state, investment in people, infrastructure and institutions that keep profits at home. Where those exist, several strategies work; where they do not, none does. The most effective approach is a combination built around whatever comparative advantage a country has, with industrialisation as its core where geography and markets allow.
