Differences in economic development between countries Revision Notes

International trade allows countries to specialise in producing goods and services where they have a comparative advantage, leading to more efficient resource use and higher total output. For example, a country rich in minerals may export raw materials while importing manufactured goods, earning foreign currency to invest in development.

Globalization refers to the increasing integration of economies through trade, investment, technology, and cultural exchange. It facilitates access to larger markets, foreign direct investment, and technology transfer, which can accelerate economic growth. However, globalization can also expose countries to global economic fluctuations and competition.

Together, international trade and globalization enable countries to expand their economic activities beyond domestic markets, promoting development through increased income and employment opportunities.

• Trade promotes specialisation and efficiency.
• Globalization connects markets and resources worldwide.
• Both can increase income and investment potential.

Income levels reflect the average earnings of individuals in a country and influence living standards and consumption capacity. Higher incomes enable better access to goods, services, and investment in infrastructure.

Productivity measures how efficiently inputs like labour and capital are used to produce output. Higher productivity means more goods and services are produced per worker, raising national income and competitiveness.

For example, a country with advanced technology and skilled workers can produce more cars per hour than one relying on manual labour, leading to higher GDP and development. Improving productivity often requires investment in machinery, training, and innovation.

• Higher income improves living standards and investment ability.
• Productivity increases output and economic efficiency.
• Investment in technology and skills boosts productivity.

Population growth affects economic development by changing the size and composition of the labour force. A growing population can provide more workers, potentially increasing output if jobs are available.

However, rapid population growth may strain resources such as food, housing, education, and healthcare, limiting improvements in living standards.

For instance, if a country’s population grows faster than its economy, unemployment may rise and per capita income may fall. Balanced population growth aligned with economic expansion supports sustainable development.

• Population growth expands labour supply.
• Excessive growth can strain resources and services.
• Sustainable growth supports economic progress.

The economic structure shows the relative size of primary (agriculture, mining), secondary (manufacturing), and tertiary (services) sectors. Developing countries often rely heavily on primary industries, which tend to have lower productivity and income levels.

As countries develop, the secondary sector grows through industrialisation, increasing manufacturing output and employment. Eventually, the tertiary sector expands, providing services like education, healthcare, and finance, which support higher living standards.

For example, a country moving from farming to car production and then to financial services typically experiences rising incomes and economic complexity. The shift towards secondary and tertiary sectors is a sign of economic development.

• Primary sector dominates in less developed countries.
• Secondary sector growth indicates industrialisation.
• Tertiary sector expansion reflects advanced development.

Savings provide the funds necessary for investment in capital goods like machinery, infrastructure, and technology, which increase productive capacity. Higher investment leads to economic growth and development.

Education improves human capital by equipping people with skills and knowledge, raising labour productivity and innovation potential.

Healthcare ensures a healthy workforce, reducing absenteeism and increasing life expectancy, which supports sustained economic activity and social stability. For example, countries investing in universal education and healthcare often achieve faster development due to a more capable and healthier population.

• Savings finance investment in productive assets.
• Education enhances skills and productivity.
• Healthcare maintains a healthy, active workforce.
