IGCSE Economics Notes /Differences in Economic Development Between Countries

5.4.1 Causes and Consequences of International Differences

Introduction

Economic development differs from country to country. Some countries have high living standards, advanced industries and strong public services, while others have low incomes, poor infrastructure and limited access to education and healthcare.

These differences are often caused by variations in income, productivity, population growth, economic structure, saving and investment, education, healthcare and natural resources.

1. Differences in Income

Meaning

Income is the money earned by individuals, households or a country. Countries differ greatly in income per head, also called GDP per capita.

Why countries differ in income

  • Some countries have more advanced industries and services.
  • Some have a more skilled and productive labour force.
  • Some have better infrastructure, such as roads, ports, electricity and internet access.
  • Some attract more investment from businesses.
  • Political stability and good government can support higher incomes.
  • Conflict, corruption and weak institutions can reduce incomes.

Consequences of differences in income

Higher income countries usually have:
  • Higher living standards
  • Better housing, nutrition and sanitation
  • More consumer choice
  • Better education and healthcare
  • More government tax revenue to spend on services
Lower income countries usually have:
  • Lower living standards
  • More poverty
  • Less access to healthcare and education
  • Poorer housing and sanitation
  • Greater dependence on aid or borrowing

2. Differences in Productivity

Meaning

Productivity is output per worker, or output per hour worked.

A country with high productivity can produce more goods and services with the same number of workers.

Why productivity differs between countries

  • Workers may have different levels of education and training.
  • Some countries use more advanced technology.
  • The quality of capital goods may be better in developed countries.
  • Workers may be healthier and therefore more efficient.
  • Better management and organisation can raise productivity.
  • Better transport and communication systems improve efficiency.
  • Political instability may reduce productivity.

Consequences of differences in productivity

High productivity leads to:
  • Lower costs of production
  • Higher output
  • Greater competitiveness in world markets
  • Higher wages
  • Faster economic growth
Low productivity leads to:
  • Higher production costs
  • Lower output
  • Lower incomes
  • Reduced competitiveness
  • Slower growth and development

3. Differences in Population Growth

Meaning

Population growth is the increase in the number of people in a country over time.

Why population growth differs between countries

  • Birth rates differ due to culture, religion, education and access to contraception.
  • Death rates differ because of healthcare, sanitation, nutrition and clean water.
  • Migration rates vary depending on job opportunities, wages, safety and political stability.
  • In less developed countries, birth rates are often high.
  • In more developed countries, birth rates are usually lower.

Consequences of differences in population growth

High population growth may cause:
  • Pressure on food, water and housing
  • Pressure on schools and hospitals
  • High dependency ratio if many children depend on workers
  • Unemployment if job creation is too slow
  • Poverty if resources cannot keep up with population increase
But it may also bring:
  • A larger future labour force
  • A larger market for goods and services
Low or negative population growth may cause:
  • Labour shortages
  • A smaller workforce
  • More elderly dependants
  • Greater pressure on pensions and healthcare
  • Lower economic growth

4. Differences in the Size of Primary, Secondary and Tertiary Sectors

Meaning of the sectors

  • Primary sector: agriculture, fishing, forestry, mining
  • Secondary sector: manufacturing and construction
  • Tertiary sector: services such as banking, transport, retail, healthcare and education

How countries differ

Less developed countries often have:
  • A larger primary sector
  • Many people working in farming or extraction
  • Less industrialisation
  • A smaller service sector
More developed countries often have:
  • A smaller primary sector
  • A large secondary and especially tertiary sector
  • More service-based jobs
  • Advanced manufacturing and high-value services

Why these differences exist

  • Richer countries have industrialised and developed service industries.
  • Poorer countries may lack capital and technology for manufacturing.
  • Education and skill levels may be too low to support advanced industries.
  • Infrastructure may be weak in poorer countries.
  • Demand changes as countries grow richer, leading to more demand for services.

Consequences of sector differences

Large primary sector:
  • Often linked to low incomes
  • Jobs may be low paid
  • Output may depend heavily on weather and commodity prices
  • Economy may be vulnerable to shocks
Larger secondary sector:
  • Can increase exports
  • Creates employment
  • Raises productivity
  • Encourages industrialisation
Larger tertiary sector:
  • Often linked to high incomes and development
  • Provides a wide range of skilled jobs
  • Can improve quality of life
  • Supports other sectors of the economy

5. Differences in Saving and Investment

Meanings

  • Saving: income not spent on current consumption
  • Investment: spending on capital goods such as machines, factories, roads and technology

Why countries differ in saving

  • In low-income countries, people may be too poor to save much.
  • In high-income countries, households and firms often have more spare income to save.
  • Confidence in banks and financial institutions may vary.
  • Interest rates may affect the willingness to save.

Why countries differ in investment

  • Some countries attract more foreign direct investment.
  • Political stability encourages investment.
  • Good infrastructure and skilled workers attract firms.
  • High saving provides funds for domestic investment.
  • Corruption, conflict and weak legal systems discourage investment.

Consequences of differences in saving and investment

High saving and investment can lead to:
  • More capital goods
  • Higher productivity
  • More jobs
  • Economic growth
  • Higher future living standards
Low saving and investment can lead to:
  • Slow growth
  • Low productivity
  • Outdated equipment
  • Weak infrastructure
  • Continued poverty

6. Differences in Education

Meaning

Education develops knowledge, skills and training.

Why education differs between countries

  • Governments in richer countries can spend more on schools and teachers.
  • Poorer countries may not have enough schools, books or trained staff.
  • Children in poor countries may leave school early to work.
  • Gender inequality may limit girls’ access to education.
  • Conflict can disrupt education.

Consequences of differences in education

Better education leads to:
  • More skilled workers
  • Higher productivity
  • Higher incomes
  • Greater ability to use modern technology
  • Better decision-making and entrepreneurship
  • Lower birth rates in many cases, especially when women are educated
Poor education leads to:
  • Low skill levels
  • Low productivity
  • Low wages
  • Limited job opportunities
  • Slower economic development

7. Differences in Healthcare

Meaning

Healthcare includes medical services, hospitals, vaccination, sanitation and disease prevention.

Why healthcare differs between countries

  • Richer countries can spend more on hospitals, doctors and medicine.
  • Poorer countries may lack trained staff and equipment.
  • Access to clean water and sanitation differs.
  • Malnutrition is more common in poorer countries.
  • Conflict and disease outbreaks damage health systems.

Consequences of differences in healthcare

Better healthcare leads to:
  • Lower death rates
  • Higher life expectancy
  • Healthier and more productive workers
  • Less time off work
  • Lower infant mortality
  • Improved quality of life
Poor healthcare leads to:
  • Higher death rates
  • Lower life expectancy
  • Lower productivity
  • More disease
  • Greater poverty
  • Slower development

8. Differences in Natural Resources

Meaning

Natural resources include oil, gas, minerals, forests, fertile land and water.

Why countries differ in natural resources

  • Some countries naturally have more mineral wealth or fertile land.
  • Climate and geography vary.
  • Some countries have access to seas, rivers or energy supplies.
  • Some countries can exploit resources better because they have the technology and investment to do so.

Consequences of differences in natural resources

Availability of natural resources can:

  • Provide raw materials for industry
  • Earn export revenue
  • Create jobs
  • Support economic growth

But natural resources do not guarantee development

A country may remain poor if:

  • Resources are badly managed
  • Profits go to foreign firms
  • Corruption is high
  • The country depends too much on one resource
  • Commodity prices fall

Lack of natural resources may:

  • Limit production possibilities
  • Increase import costs
  • Slow industrial development

However, countries with few natural resources can still become developed if they have:

  • Skilled labour
  • Good education
  • Strong infrastructure
  • Advanced technology
  • Efficient industries and services

How These Factors Are Connected

These causes are closely linked.

For example:

  • Better education improves productivity
  • Higher productivity raises income
  • Higher income allows more saving and investment
  • More investment improves infrastructure, education and healthcare
  • Better healthcare creates a healthier workforce
  • Stronger growth can shift an economy from the primary sector to the secondary and tertiary sectors

On the other hand:

  • Low income can lead to low saving
  • Low saving means low investment
  • Low investment keeps productivity low
  • Low productivity keeps income low

This is sometimes called a cycle of poverty.
