0455 · 5.4Differences in economic development between countries

Development, growth and productivity

0:00Imagine two farmers who work equally long days, but have very different equipment. One uses hand tools, while the other has a tractor and reliable irrigation. Their effort may be similar, yet their harvests can differ greatly. Differences in economic development often begin with differences in what people can produce and the opportunities available to them. Economic development is an improvement in economic welfare, shown by higher living standards. People's living standards cover their material welfare and quality of life.

0:27Development also brings less poverty and wider access to education, healthcare and basic necessities. Countries differ in all of these outcomes, and each difference has causes as well as consequences. Countries described as more developed generally have higher average incomes and better access to education and healthcare. Less developed countries usually face greater difficulties providing these opportunities. These are broad patterns, with considerable variation within each group. Every country contains people whose circumstances differ from its national average.

0:59Economic growth is an increase in real Gross Domestic Product, or real G D P. This measures the value of output produced within a country, adjusted for price changes. Growth can provide more resources for improving welfare. The benefits become broader when people gain access to better housing, schooling and medical care. Productivity is output per unit of input. When the input is labour, economists measure output per worker, or per worker per hour.

1:24Better machinery, useful skills and reliable electricity can help people produce more during their working day. Workers in more developed countries usually have more machinery and training to work with, which helps explain their higher productivity. Suppose a workshop gains equipment that makes accurate cutting easier. Workers waste fewer materials and finish more products each hour. Lower costs per item can help the business expand, while higher productivity can support increased wages.

1:51The resulting income gives households greater purchasing power and provides funds for further improvements. Labour productivity equals output divided by the number of workers. For example, the workshop produces four hundred and eighty chairs each week with twelve workers. Dividing four hundred and eighty by twelve gives forty chairs per worker per week. With improved tools, weekly output reaches six hundred chairs using the same workforce. Labour productivity is now six hundred divided by twelve, which equals fifty chairs per worker per week.

2:21The calculation spreads total production across the workforce to measure average output per worker. Here, improved equipment allows the same workers to produce more. Higher productivity creates the possibility of better living standards, although the distribution of additional income matters. Workers benefit more directly when their earnings rise or goods become more affordable.

Income, saving and poverty

2:42Average incomes differ widely between countries, mainly because productivity differs. People receive income from work, from owning resources and from government transfers. Higher household incomes allow greater spending on food, housing and other necessities. Governments in higher-income countries also collect more tax revenue, which helps finance schools, hospitals and infrastructure for future growth. Average income describes a country as a whole, but individuals receive different amounts. Prices also affect how much a given income can buy.

3:12A meaningful comparison therefore considers purchasing power and how widely income is shared. Higher national income offers greater opportunities for improving welfare when the benefits reach the population. Saving is income that is not spent, while investment is expenditure on capital goods such as machinery and equipment. In many less developed countries, households with low incomes spend most of their earnings on necessities. They have little left to save, which limits the funds available for investment.

3:39In more developed countries, higher incomes leave more room for saving. Banks can use deposited savings to provide loans for business equipment. When available funds are limited, firms may struggle to purchase machinery or expand production. Little investment leaves productivity low, which restricts incomes in turn. Each link reinforces the next, so the whole chain is called the vicious circle of poverty.

Education, health and development

4:01The circle can be broken at any of its links. Investment from abroad, foreign aid or government spending on infrastructure can raise productivity even when domestic savings are limited. Higher incomes then allow households to save some of their additional earnings. Firms also need confidence that they can sell their output before they invest. Education strengthens this process because machinery becomes more useful when workers have the skills to operate it effectively.

4:27Literacy, numeracy and technical training help people follow instructions, solve problems and adapt to new methods. Better qualifications can widen access to higher-paid employment. Increased earnings then help families afford further education. Education is therefore both a cause and a consequence of the gap in development between countries. Higher incomes help fund teachers, classrooms and learning materials. Where resources are scarce, families may struggle with school costs or need children to contribute to household earnings.

4:55These pressures can restrict skill development and future productivity. Good health raises both welfare and the ability to work. Effective treatment reduces time lost through illness, while preventive care helps people remain healthy. Workers can attend more regularly and perform their jobs well. Children also benefit through better attendance and improved opportunities to learn. Where medical services are limited, untreated illness can reduce earnings and put pressure on family budgets.

5:22Higher-income countries can spend more on hospitals, doctors and medicines, through both household spending and public revenue. Better health directly improves living standards because people experience less illness and live longer. A healthier workforce also raises productivity, which supports economic growth. Population growth is an increase in the number of people living in a country. If population rises faster than production, average output per person falls. More people must share an amount of output that expands more slowly.

5:52Schools, healthcare services and housing also need additional resources to maintain their existing availability per person. Many less developed countries have faster population growth, with a large share of the population made up of children. Families and governments must support more people before they enter paid employment. However, a growing population can eventually provide a larger workforce and more customers. Education, suitable jobs and investment help turn that potential into higher living standards.

Population growth and economic sectors

6:20Development can also influence population growth. Improved child survival, wider educational opportunities and access to family planning can encourage smaller families over time. Better healthcare may initially accelerate population growth because death rates fall before birth rates decline. Population patterns therefore change through several connected influences, rather than income alone. The primary sector extracts or harvests natural resources, as in farming, fishing and mining. Manufacturing and construction belong to the secondary sector, which processes materials or creates buildings.

6:54The tertiary sector provides services, including transport, retailing and healthcare. Their relative sizes can be compared using shares of employment or national output. Less developed economies often have large primary sectors, especially in employment. Small farms may have limited equipment, which can restrict output per worker and income. Dependence on agricultural production also creates exposure to poor harvests. However, mechanised farming or valuable mineral extraction can generate high productivity and substantial earnings.

7:25Industrial development can create manufacturing jobs and opportunities to process raw materials into more valuable products. This requires machinery, skilled workers and reliable transport. More developed economies generally have large tertiary sectors because higher incomes increase demand for services. Specialised activities, such as medical treatment and engineering advice, also require substantial training. A large service sector can also contain many workers in low-paid or informal activities. Productivity and earnings within each sector therefore help explain its contribution to development.

7:58Expansion of manufacturing or services can support growth when workers gain suitable skills and productive equipment. Cleaner technology helps protect health and resources as production expands.

Natural resources and development

8:09Countries differ greatly in their fertile land, forests, mineral deposits and water. These natural resources are supplied by nature and can be used in production. Their availability helps explain international differences in output and income. Resource extraction can create jobs and generate revenue that finances education, healthcare and infrastructure. Turning those opportunities into lasting development requires investment, skills and careful management. Mineral deposits need equipment and transport before they can generate substantial earnings.

8:40Heavy dependence on one resource can expose income to changing prices. Pollution, soil damage and resource depletion can also reduce present welfare and limit future production. Countries with limited natural resources can develop through skilled workers, manufacturing and productive services. Resource-rich economies benefit more when earnings support a wider range of activities and improved public services. This shows why development reflects several interacting influences. Natural wealth offers an opportunity whose consequences depend on how it is used.

Exam answers and recap

9:11An examination question could ask you to explain how improved education may increase living standards. Explain means set out purposes or reasons, so you show why or how something happens. Start with the named cause and trace its effects. A strong answer connects education to skills, productivity, earnings and the goods and services people can afford. Improved education gives workers skills that help them perform tasks more efficiently. Their labour productivity rises, so each worker produces more output per hour.

9:42Employers may pay higher wages when workers make a greater contribution to production. Higher household income then allows greater spending on necessities and other goods and services, which raises living standards. Define asks for a precise meaning, state asks you to express points in clear terms, and analyse asks you to examine relationships in detail. A multiple-choice question on the vicious circle of poverty tests the order of its links.

10:07The correct order runs from low income to low saving, then to low investment and low productivity, and finally back to low income. Discuss means write about an issue in depth in a structured way, with both sides considered. Suppose the question asks whether abundant natural resources will increase economic development. Supporters argue that extraction creates earnings, which can finance productive investment and public services. These improvements raise output and widen access to education and healthcare, so development increases.

10:36Critics point out that dependence on one resource exposes income to falling world prices, while pollution can damage health and livelihoods. Benefits may also be concentrated among a small group, so most people's living standards improve little. On balance, abundant natural resources usually increase economic development when their earnings are spent on education, healthcare and other industries. This is because broad spending spreads the benefits and reduces dependence on a single price.

11:03A common weakness is a missing link in the chain of reasoning, so show every step from the cause to the outcome asked about. Treat sector patterns as general tendencies, and check whether figures refer to employment or output. When comparing countries, consider average income alongside access to services and the distribution of benefits. International differences in economic development have both causes and consequences. Productivity affects income, while saving and investment influence the equipment available for future production.

11:34Education and healthcare strengthen people's opportunities and their ability to work. Population growth, economic sectors and natural resources shape the pressures and possibilities facing each country. These influences reinforce one another across time. Low income can restrict investment and public services, which makes future progress harder. Better skills, health and equipment can create a stronger foundation for growth and improved living standards. Understanding those connections lets you explain why development differs between countries and how those differences can change.
