Economic development · Lesson 7 of 16

Aid, foreign capital, debt and the Bretton Woods institutions

Poor countries often need more resources than they can raise at home: for investment and, just as important, for imports. This lesson starts with the two-gap model that explains what foreign capital is for, goes through the forms it takes (aid, foreign direct investment, remittances and debt), looks at the argument over whether aid works, and sets out what the IMF and the World Bank Group do and when they began. A two-gap lab and World Bank data on aid, FDI and remittances let you test the ideas.

The short answer

Why do developing countries need foreign capital, and who provides it?

The lesson separates what foreign capital is for (the two gaps) from who gives it and on what terms, since exam questions mostly ask about the institutions and their dates and about the definitions.

  • Two gaps: investment needed minus saving; imports needed minus exports. Foreign capital must fill the larger.
  • Forms: aid (ODA), foreign direct investment (10% or more of voting power), portfolio flows, remittances and loans.
  • Does aid work? Disputed: Burnside–Dollar found it works with good policies; later work finds the result fragile.
  • Institutions: the IMF lends short-term against balance of payments problems; the World Bank lends long-term for development.

Saving and investment
To grow at rate g with capital–output ratio v, an economy must invest v × g of its output; if domestic saving falls short, the shortfall must be financed from abroad.
Balance of payments
A current account deficit (imports of goods, services and income above exports) is financed by net inflows on the capital account: aid, FDI, portfolio flows, loans.

What foreign capital is for

The two-gap model

Hollis Chenery and Alan Strout (1966) saw foreign assistance as filling two distinct shortages. The first is the familiar saving gap: to grow at rate g with a capital–output ratio v, the economy must invest v·g of its output, and if domestic saving s is less, the gap is v·g − s (all as shares of output). The second is a trade gap, or foreign-exchange gap: development needs imports, such as machinery and fuel, that cannot be made at home, and exports may not earn enough to pay for them. If imports needed are m and exports are x, the gap is m − x.

In accounting terms both gaps are equal after the event, since saving plus foreign borrowing equals investment, and imports equal exports plus foreign borrowing. But before the event they can differ, and the one that is larger decides how much foreign capital is needed (the other is then met with room to spare). If the trade gap binds, extra aid for investment will not be spent usefully unless it comes as foreign exchange; if the saving gap binds, policies to raise saving matter more than exports. Rosenstein-Rodan (1961) had earlier argued the case for aid as a way to finance the big push of Lesson 5.

Fill the gaps

The lab is a one-year snapshot with all quantities as shares of output. In the base case an economy wants to grow at 7 per cent with a capital–output ratio of 4, so it needs to invest 28 per cent of output; saving is 20 per cent, a saving gap of 8 points. It needs imports of 25 per cent of output and earns exports of 10 per cent, a trade gap of 15 points. The trade gap is larger, so foreign capital of 15 per cent of output is needed, and it must come as foreign exchange. Try raising exports and watch the binding gap switch.

Domestic saving20%
Trade gap
Imports needed25%
Export earnings10%
Saving gap8% of outputinvestment − saving
Trade gap15% of outputimports − exports

Saving nearly covers the investment needed, but the economy cannot earn enough foreign exchange to pay for its imports: aid is needed to buy imports, not to add to saving.

The sources

Aid, FDI, remittances and debt

Aid (official development assistance, ODA) is official finance given on concessional terms to promote development. It is bilateral (donor to recipient) or multilateral (through the World Bank, regional banks or the UN). The UN General Assembly adopted in 1970 a target that rich countries give 0.7 per cent of their gross national product as ODA. Aid is tied when the recipient must spend it on goods and services from the donor, which raises its real cost. Since 2018 the OECD counts the grant element of loans differently by income group, so that long-run comparisons need care.

Foreign direct investment is investment in which the foreign investor holds 10 per cent or more of the voting power in the enterprise (the IMF’s balance of payments manual), which gives a lasting interest and some control; a smaller holding in shares or bonds is portfolio investment. FDI brings management and technology as well as capital and is less volatile than portfolio flows, which can reverse quickly in a crisis. Remittances are the money sent home by migrants (the World Bank’s series, personal remittances, adds personal transfers to the compensation of employees); they go directly to households and are often more stable than other flows. Debt is the fourth: loans must be repaid, so a country that borrows for investment needs growth and exports to service it. The debt crises of the 1980s led to the structural adjustment lending of Lesson 6, and later to the Heavily Indebted Poor Countries Initiative (1996; enhanced 1999) and the Multilateral Debt Relief Initiative (agreed in 2005).

Why the form matters

Aid and concessional loans fill the saving gap or the trade gap but create no return of their own; FDI brings technology and pays profits only when it earns them; portfolio flows can leave at once; remittances come with the migrant’s earnings and are spent by families. A country’s vulnerability depends on the mix.

Evidence

External finance in the data

Use the panel to compare. Aid was a sizeable part of national income for many African countries: Kenya received 14.4 per cent of GNI as net ODA in 1990, Ghana 12.4 per cent in 2000, Ethiopia 9.3 per cent in 2010; India’s fell from 2.0 per cent in 1960 to 0.07 per cent in 2023. FDI inflows in China reached 3.9 per cent of GDP in 2010 and Vietnam’s 5.4 per cent, while India’s were 1.6 per cent. Remittances are very large for some small countries: 26.2 per cent of GDP in Nepal in 2023, against 3.4 per cent in India and 9.0 per cent in the Philippines.

The debate

Does aid work?

Craig Burnside and David Dollar (2000) found that aid raises growth in countries with good fiscal, monetary and trade policies and does little under poor policies, which supported the argument that aid should be directed to countries with good policies. Easterly, Levine and Roodman (2004) re-estimated their results with more countries and years and found that the interaction between aid and policy did not hold up (summarised in Easterly 2003). Rajan and Subramanian (2008) used a different approach and found little firm evidence of a positive or negative effect of aid on growth. Jeffrey Sachs (The End of Poverty, 2005) argues that a large and well-planned increase in aid could end extreme poverty and break poverty traps; William Easterly (The White Man’s Burden, 2006) and Dambisa Moyo (Dead Aid, 2009) argue that aid has failed or harmed.

Two mechanisms are often cited against aid. Dutch disease: a large inflow raises the real exchange rate and makes exports uncompetitive (Corden and Neary, 1982, describe it for a resource boom). And aid can weaken the accountability of governments that rely on it more than on taxes. For the countries that have grown fast, aid played a small part; India is among the countries that have moved from aid recipient to little aid. The Lucas paradox, that capital does not flow to poor countries as theory expects, is in the growth module.

The institutions

The IMF and the World Bank Group

The two institutions were planned at the Bretton Woods conference (1–22 July 1944) (UOH 2010: the Bretton Woods institutions are the IMF and the IBRD). They have different jobs.

  • IMF (financial operations began 1 March 1947): supports members with balance of payments problems through short and medium-term loans, watches members’ policies (surveillance), and issues the Special Drawing Right (created 1969). It gives stabilisation loans (UOH 2010) and attaches conditions: for structural adjustment loans, devaluing an overvalued exchange rate and reducing the fiscal deficit (UOH 2012). The Extended Fund Facility, set up in 1974, supports structural reforms to address balance of payments problems of a long-term character (UGC NET 2023).
  • World Bank Group: long-term finance for development. The IBRD began operations in 1946; the IFC (private sector) in 1956; the IDA (concessional credit to the poorest countries) in 1960; ICSID (settlement of investment disputes), whose convention entered into force in 1966; and MIGA (guarantees against political risk) in 1988. The Bank began structural adjustment lending in 1980.

India is a member of the IMF (it joined in 1945) and of the IBRD, IDA, IFC and MIGA; it has neither signed nor ratified the ICSID Convention (UGC NET 2024 asks which World Bank Group institutions India belongs to: IDA, IFC, MIGA and IBRD). Headquarters: the IMF, the World Bank and the IDA are in Washington DC, GATT was in Geneva, and the Asian Development Bank is at Mandaluyong, in the Philippines; the IDA is not in New York (UGC NET 2023). Questions on the Bretton Woods exchange rate system are in the exchange-rate regimes lesson.

What conditionality is for

A loan with conditions is meant to make sure the borrower can repay by correcting the cause of its balance of payments problem. Critics say the conditions have been too uniform and have cut spending that the poor depend on. The Washington Consensus and its critics are in Lesson 6.

Watch out for

The mistakes examiners are fishing for

  • Giving the IMF the World Bank’s job. The IMF handles balance of payments problems and stabilisation; the Bank, long-term development finance.
  • Treating the saving gap as the only gap. The trade gap can bind even when saving is adequate.
  • Mixing FDI with portfolio flows. The dividing line is 10% of the voting power.
  • Giving the year the IMF was founded when asked the year it began operations. The Articles were agreed in 1944, and operations began on 1 March 1947.
  • Calling the evidence on aid settled. It is disputed, and results change with the data and the method.

Frequently asked questions

What is the two-gap model?

The two-gap model of Chenery and Strout (1966) says a developing country can be held back by either of two shortages. The saving gap is investment needed for a target growth rate minus domestic saving; the trade (foreign exchange) gap is the imports it needs minus what it earns from exports. Foreign capital has to fill the larger of the two gaps, which is why aid can be needed even when saving seems adequate, if the binding constraint is foreign exchange.

What is official development assistance?

Official development assistance (ODA) is government aid designed to promote the economic development and welfare of developing countries, given on concessional terms: grants or loans with a low interest rate and long repayment period. The United Nations adopted a target in 1970 that rich countries give 0.7 per cent of their gross national product as ODA. Aid is tied when it must be spent on goods and services from the donor.

What is the difference between FDI and portfolio investment?

Foreign direct investment is an investment in which the foreign investor holds 10 per cent or more of the voting power in an enterprise, giving a lasting interest and some control. Portfolio investment is a smaller holding, in shares or bonds, with no control. FDI is generally more stable than portfolio flows, and brings technology and management as well as capital.

Does foreign aid promote growth?

The evidence is disputed. Burnside and Dollar (2000) found that aid raises growth in countries with good policies. Easterly, Levine and Roodman (2004) found that this result did not survive the inclusion of more data, and Rajan and Subramanian (2008) found little firm evidence of an effect of aid on growth either way. Jeffrey Sachs argues that a large increase in aid could end extreme poverty; William Easterly and Dambisa Moyo argue that aid has done little or harm.

What do the IMF and the World Bank do?

The International Monetary Fund, which began financial operations in 1947, provides short-term loans to countries with balance of payments difficulties, often with conditions, and monitors members' economies. The World Bank, whose first part, the IBRD, began operations in 1946, lends for long-term development and, through the International Development Association (1960), gives concessional credit to the poorest countries. Both were set up at the Bretton Woods conference of July 1944.

Which World Bank Group institutions is India a member of?

India is a member of the IBRD, the International Development Association, the International Finance Corporation and the Multilateral Investment Guarantee Agency. It has neither signed nor ratified the ICSID Convention, so it is not a member of the International Centre for Settlement of Investment Disputes, the fifth part of the group.
