OCR A Level Economics: Development, alternative measures and international bodies (H460)

This guide covers the development statements of the Component 2 (Macroeconomics) topic “Economic growth and development” in the OCR A Level Economics specification (H460), Version 3.0 (June 2026), for first assessment in 2021. It teaches development and sustainable development, how they differ from growth, how ODA and trade can help, the measures of progress (GDP, HDI, Genuine Progress Indicator and others), growth and happiness, and the international organisations. Growth measurement, recession and real versus nominal GDP are covered elsewhere. All data below is invented and illustrative.

1. Development and sustainable development

Economic development is a sustained improvement in people’s living standards and wellbeing. It is wider than income: health, education, poverty, freedom and choice, and economic structure all matter.

Sustainable development is progress that satisfies present needs without closing off later generations’ ability to satisfy their own. It has economic, social and environmental strands. The key idea is that the environment is a stock of natural capital as well as a source of amenities. Output financed by using up that stock cannot continue indefinitely.

2. Growth versus development

Growth is a rise in real GDP. It normally helps development, since it enlarges the pool of resources for hospitals, schools and infrastructure. It does not guarantee it. A chain of reasoning to use:

1. Growth raises average income, but the average hides distribution. If a narrow group takes the gains, poverty may barely change.
2. Growth must be turned into services. If tax revenue is spent on other things, health and schooling do not improve.
3. Growth can come with falling wellbeing: long hours, pollution, loss of community.
4. Development can occur with little growth, for example through a cheap vaccination programme, though gains usually slow without growth.

Worked example: same income, different development

Use simplified goalposts: life expectancy 25 to 85 years; mean years of schooling 0 to 15; expected years of schooling 0 to 18; GNI per head 100 to 75,000 (dollars, log scale). Each dimension index is (actual - minimum) / (maximum - minimum). The education index is the average of the two schooling indices. HDI is the geometric mean (cube root of the product).

	Country A	Country B
Life expectancy	72	78
Mean / expected schooling	8 / 12	10 / 14
GNI per head	9,000	9,000
Health index	0.783	0.883
Education index	0.600	0.722
Income index	0.680	0.680
HDI	0.684	0.757

Income index = (ln 9,000 - ln 100) / (ln 75,000 - ln 100) = 0.680. Country A: (0.783 x 0.600 x 0.680) to the power 1/3 = 0.684. Country B: (0.883 x 0.722 x 0.680) to the power 1/3 = 0.757.

The same income per head gives different development. Now suppose Country A’s GNI per head rises 40% to 12,600 with no change in health or schooling. The income index rises to 0.731 and HDI to 0.700 (from 0.684). Growth of 40% gives only 2.4% more HDI, because income is logged (diminishing returns to income) and the other two dimensions are unchanged.

3. Growth, structural change and sustainable development

Primary activity is mining and farming, secondary activity is making and building things, and tertiary activity is services. Development usually involves a shift of output and jobs from primary towards secondary and then tertiary activity. Invented data for Country C, share of output (%):

Year	Primary	Secondary	Tertiary
2000	38	22	40
2010	25	30	45
2020	12	28	60

Evaluating the link to sustainable development:

• Moving workers from low-productivity farming to factories and offices raises productivity, income and tax revenue.
• The secondary phase often raises pollution and resource use per unit of output; a service-based economy may be less intensive, though it can export its pollution by importing goods.
• Growth can fund cleaner technology and regulation, as in the environmental Kuznets curve idea that pollution first rises and then falls with income. Whether this happens depends on policy and on the pollutant.
• Depleting natural capital to grow (mining, clearing forest) boosts GDP now but lowers future potential, so measured growth overstates sustainable gains.

Judgement: growth makes sustainable development easier to afford but does not secure it. The outcome depends on the type of growth, the policies and the time period.

4. ODA and trade

Overseas Development Assistance (ODA) is government aid to developing countries intended mainly to promote development. It can take the form of grants or low-interest loans.

How it promotes growth and development: it fills a gap in saving and foreign exchange, funds investment in infrastructure, schools and health, supports technology transfer and relieves poverty directly.

Limits: aid may be tied to purchases from the donor, can be misused, may weaken tax collection, and can push up the exchange rate.

Worked example (invented). Donor Country D has GNI of 1,800bn and gives 6.3bn in ODA. Share = 6.3 / 1,800 = 0.35% of GNI. The United Nations target is 0.7%, which would be 1,800 x 0.007 = 12.6bn, a shortfall of 6.3bn. Recipient Country E has GNI of 24bn and receives 1.2bn: 5% of GNI, large enough to matter. If the aid is tied and goods cost 25% more than on the open market, 1.2bn buys only 1.2 / 1.25 = 0.96bn of goods, a loss of 0.24bn.

Trade raises growth by widening markets (exports), bringing in capital goods and technology, and allowing specialisation and scale economies. Exports are part of aggregate demand.

Worked example: contribution of net exports. Country F (invented), GDP = C + I + G + (X - M):

Year	C	I	G	X	M	GDP
1	60	20	24	30	34	100
2	70	26	26	42	40	124

GDP growth = 24%. Net exports moved from -4 to +2, a change of 6, so they contributed 6 of the 24 percentage points (C 10, I 6, G 2).

Risks: dependence on primary exports. Terms of trade = export prices relative to import prices, as an index: (X price index / M price index) x 100. If export prices stand at 112 and import prices at 140 (base 100): 112 / 140 x 100 = 80, a fall of 20%. Then 140 / 112 = 1.25 times the export volume is needed to pay for the same imports. Primary prices are volatile, and some economists argue their prices drift down against manufactured goods in the long run.

5. Measuring progress: GDP, HDI, GPI and others

GDP per head: simple, regularly produced and comparable, and linked to resources available. It ignores distribution, unpaid work, the informal economy, environmental damage, leisure and what is produced.

Human Development Index (HDI): combines health (life expectancy), education (years of schooling) and income (GNI per head, logged) into one number between 0 and 1, using a geometric mean. It is broader than GDP and simple to compare. But it leaves out inequality, the environment, freedom and political rights, weights dimensions equally, and its dimensions are highly correlated with income anyway.

Genuine Progress Indicator (GPI) starts from consumption and adjusts it: subtract inequality, pollution, resource depletion and crime costs; add the value of unpaid household work and volunteering.

Worked example (invented, billions of units).

Item	Year 1	Year 2
Consumption	600	640
Inequality adjustment	-80	-96
Household work and volunteering	+110	+111
Pollution, depletion, crime, long-run damage	-155	-199
GPI	475	456

GDP rose from 900 to 990 (+10%), yet GPI fell by 4.0% (456 / 475 - 1). Growth in GDP overstated the improvement in welfare. Weakness: many adjustments need money values for things that have no market price, so they rest on judgement.

Other social and cultural indicators include inequality measures, literacy, infant mortality, access to clean water, trust, crime, time spent in leisure or with family, and the strength of cultural life. They capture what money misses but are hard to combine, culturally dependent and sometimes subjective.

Evaluation: no single measure is best. GDP shows resources, HDI broad living standards, GPI sustainability and distribution; a dashboard of several is better.

6. Growth and happiness

The Easterlin Paradox: within a country at one time, richer people report being happier, yet as a country grows richer over time average happiness does not rise much. Invented data for Country G:

Year	GDP per head index	Average life satisfaction (0 to 10)
1990	100	6.8
2000	150	6.9
2010	210	6.8
2020	260	6.9

GDP per head rose 160% while satisfaction rose 0.1 points. In 2020 the top income group scores 7.8 and the bottom group 5.9, a gap of 1.9 points.

Possible explanations: people compare themselves with others (relative income), adapt to higher living standards, and care about things growth may not improve, such as security, health and trust. Counter-arguments: the finding depends on the data, later research by others has questioned it, very poor countries show a strong link between income and happiness, and happiness surveys are subjective.

The Office for National Statistics (ONS) Measuring National Well-being programme was launched in 2010. It reports on ten areas, including personal well-being, relationships, health, what we do, where we live, personal finance, the economy, education and skills, governance and the environment, and asks people directly about life satisfaction, feeling that what they do is worthwhile, happiness and anxiety. It treats GDP as one indicator among many.

7. International organisations

IMF: keeps watch over member economies (surveillance), lends when a country cannot pay its way externally, and offers technical help. Loans carry conditions, usually on government spending, taxes and exchange rates. Role in development: stabilises economies and restores confidence. Criticisms: austerity conditions can deepen recessions and hurt the poor; policies may be one-size-fits-all.

Worked example (invented). Country H has GDP of 80bn. As a loan condition it cuts government spending by 3bn. With a multiplier of 1.2, the fall in GDP is 3 x 1.2 = 3.6bn, which is 4.5% of GDP. The deficit falls, but output and jobs fall too.

World Bank: provides loans and grants, mostly for projects (roads, schools, health, water) and for poverty reduction, plus advice. Strengths: long-term finance, expertise, a focus on poverty. Weaknesses: project failure, debt burdens, conditions attached, and donor country influence on decisions.

World Trade Organization (WTO): runs the rules for trade between members, hosts negotiations for tariff and other barrier reductions, and settles disputes. Special treatment for developing members exists. Role in development: freer access to markets can raise exports.

Worked example (invented). A partner cuts its tariff on a good from 25% to 10%. At a base price of 100, the consumer price falls from 125 to 110, a fall of 12.0%. If demand for this import has PED of -2.5, quantity demanded rises by 30%, helping the exporter.

Effectiveness: judge by evidence (did growth and poverty improve?), whether the benefits reach the poorest, and the scale of the problem. Agreeing wider deals has proved slow, agriculture remains contentious, and the benefits of liberalisation depend on whether a country can diversify.

Common errors

• Using growth and development interchangeably, or saying growth always improves development.
• Describing HDI without saying what it leaves out.
• Using a rise in GDP as proof that sustainable development has improved.
• Writing about the IMF, World Bank and WTO as one body; each has a different function.
• Listing criticisms with no judgement of their weight.
