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
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.
