Globalisation: Causes, Benefits, Costs and Impact on Singapore — Complete A-Level Economics Guide

Globalisation refers to the increasing integration and interdependence of economies through the growing movement of goods, services, capital, technology, information and people across national borders.

For A-Level Economics, students should avoid treating globalisation as simply “more international trade”. A stronger answer recognises that globalisation involves:

Trade integration + foreign investment + global production networks + technology transfer + labour mobility + financial integration.

Its effects are mixed. Globalisation can raise productivity, growth and consumer welfare, but it can also increase exposure to external shocks, structural unemployment, inequality and environmental pressures.

What Is Globalisation?

Globalisation occurs when national economies become more closely connected.

This can take place through:

international trade;
foreign direct investment;
global supply chains;
movement of labour;
international financial flows;
technology transfer;
digital connectivity.

As these links deepen, economic events in one country can have increasingly important effects on other countries.

Globalisation vs International Trade

International trade is one part of globalisation.

Trade refers mainly to the exchange of goods and services between countries.

Globalisation is broader.

It also includes:

multinational corporations;
cross-border investment;
international labour movement;
global financial markets;
technology and information flows.

Therefore:

Trade is a component of globalisation, not the whole of it.

What Has Caused Globalisation?

Major causes include:

falling transport costs;
improved communications technology;
trade liberalisation;
growth of multinational corporations;
foreign direct investment;
financial liberalisation;
global supply chains;
rising incomes;
international agreements.

1. Falling Transport Costs

Improvements in:

container shipping;
aviation;
logistics;
ports;

have reduced the cost of moving goods around the world.

Therefore:

International trade becomes more profitable.

Firms can locate different stages of production in different countries.

Containerisation

Standardised shipping containers reduce:

loading time;
handling costs;
damage;
transport delays.

Therefore:

International transportation becomes cheaper and more reliable.

This supports global supply chains.

2. Improvements in Communication

The internet, cloud computing and digital communication allow firms to coordinate activities across countries.

A company can:

design products in one country;
manufacture components in another;
provide customer support elsewhere.

Therefore:

Geographical distance becomes less important for many economic activities.

3. Trade Liberalisation

Governments have reduced some:

tariffs;
quotas;
regulatory barriers.

This lowers the cost of international trade.

Therefore:

Imports and exports increase.

Countries become more economically integrated.

4. Multinational Corporations

A multinational corporation operates in more than one country.

MNCs may locate activities according to differences in:

labour costs;
skills;
infrastructure;
market size;
taxation;
natural resources.

Therefore:

Production becomes internationally dispersed.

5. Foreign Direct Investment

FDI occurs when a firm establishes or acquires a lasting business interest in another economy.

Examples include:

building a factory;
opening a regional headquarters;
acquiring a foreign company.

FDI deepens global integration because it connects:

capital
production
employment
technology

across borders.

6. Financial Globalisation

Capital can move more easily between countries.

Investors can purchase:

foreign shares;
bonds;
property;
businesses.

Therefore:

Domestic investment is less dependent solely on domestic saving.

7. Global Supply Chains

Modern products are often produced in stages across multiple countries.

For example:

Design in Country A
components in Country B
assembly in Country C
marketing in Country D.

Therefore:

Countries become mutually dependent.

Global Value Chains

A global value chain divides production according to:

relative costs;
skills;
technology;
logistics.

Countries may specialise in particular stages of production rather than entire products.

Singapore and Global Value Chains

Singapore is strongly connected to regional and global production networks.

This allows firms to specialise in higher-value activities while importing many necessary:

raw materials;
components;
intermediate goods.

Therefore:

High imports and exports can reflect deep integration rather than economic weakness.

Globalisation and Comparative Advantage

Globalisation allows countries to exploit comparative advantage more fully.

If Country A has lower opportunity cost in producing electronics:

It can specialise more heavily.

Country B may specialise in agriculture.

Trade then allows both countries to consume a wider range of goods.

Comparative Advantage Chain

Comparative advantage
→ specialisation
→ international trade
→ more efficient resource allocation
→ world output ↑
→ potential welfare ↑.

Globalisation expands the scale on which this process can occur.

Globalisation and Economies of Scale

A domestic firm may face a small local market.

Globalisation gives access to:

millions of foreign customers.

Output ↑.

Therefore:

Average costs may fall through economies of scale.

Singapore Application

Singapore’s domestic market is relatively small.

Access to global markets allows firms operating in Singapore to:

expand output;
specialise;
achieve economies of scale.

Therefore:

Global market access is particularly important for a small economy.

Benefit 1: Economic Growth

Globalisation can increase actual economic growth through:

Exports ↑
→ AD ↑
→ real GDP ↑.

Foreign investment may also increase:

I ↑
→ AD ↑.

Therefore:

Actual growth can rise.

Multiplier Effect

Exports and investment are injections.

X ↑ / I ↑
→ incomes ↑
→ consumption ↑
→ further incomes ↑.

Therefore:

Globalisation can create multiplier effects.

Long-Run Growth

Globalisation can also increase potential growth.

FDI can increase:

capital stock.

Technology transfer can increase:

productivity.

Trade competition can increase:

efficiency.

Therefore:

LRAS may shift right.

Benefit 2: Consumer Choice

Globalisation allows consumers to purchase goods from many countries.

Therefore:

Product variety ↑.

Consumers gain access to:

more brands;
different technologies;
different price points.

Consumer welfare may rise.

Benefit 3: Lower Prices

Imports expose domestic producers to international competition.

Consumers can buy goods produced at lower costs abroad.

Therefore:

Price ↓.

Real purchasing power ↑.

Material standard of living may improve.

Competition Effect

Domestic firms must compete with foreign producers.

Therefore:

They may:

reduce costs;
improve quality;
innovate.

This can increase productive and dynamic efficiency.

Benefit 4: Foreign Direct Investment

FDI can bring:

capital;
employment;
technology;
management expertise;
access to international markets.

Therefore:

Host-country productive capacity may increase.

Example

An MNC establishes an advanced manufacturing facility.

Investment ↑.

Capital stock ↑.

Workers receive training.

Knowledge spreads to local suppliers.

Therefore:

Potential output can rise.

Technology Spillovers

Employees trained by an MNC may later move to domestic firms.

Local suppliers may learn new:

production techniques;
quality standards;
management practices.

Therefore:

Productivity gains can spread beyond the foreign company itself.

Benefit 5: Employment

FDI and export growth can increase:

Derived demand for labour.

Therefore:

Employment ↑.

Household income ↑.

Consumption ↑.

Benefit 6: Greater Specialisation

Globalisation enables firms and workers to specialise more deeply.

Specialisation can increase:

productivity;
expertise;
efficiency.

Therefore:

Output per worker may rise.

Benefit 7: International Competition

Greater competition can reduce monopoly power.

Domestic firms face substitutes from overseas.

Therefore:

Demand may become more price elastic.

Firms have less ability to charge excessively high prices.

Benefit 8: Innovation

A firm facing global competition cannot easily remain inefficient.

To survive, it may invest in:

R&D;
automation;
product development.

Therefore:

Globalisation can stimulate dynamic efficiency.

Benefit 9: Capital Access

Countries with insufficient domestic saving can attract foreign capital.

Therefore:

Investment may rise.

This can finance:

factories;
infrastructure;
technology.

Hence:

Potential growth ↑.

Benefit 10: Knowledge Transfer

Ideas move across borders through:

trade;
FDI;
migration;
international education.

Therefore:

Innovation can spread faster.

Globalisation and Productivity

The productivity channel is central.

Foreign competition ↑
→ inefficient firms restructure or exit.

Resources shift towards:

more productive firms.

Therefore:

Average economy-wide productivity may rise.

Creative Destruction

Globalisation can contribute to creative destruction.

Less competitive industries shrink.

More efficient or innovative industries expand.

This can raise long-run productivity.

However:

The transition can create substantial adjustment costs.

Cost 1: Structural Unemployment

Import competition can reduce demand for domestically produced goods.

Domestic firms may close.

Workers lose jobs.

If workers lack the skills needed in expanding industries:

Structural unemployment ↑.

Example

Low-skilled manufacturing relocates overseas.

Domestic manufacturing workers become unemployed.

But new jobs may be in:

technology;
finance;
healthcare.

Workers cannot immediately move into these sectors.

Therefore:

Occupational immobility creates unemployment.

Short Run vs Long Run

In the long run:

Workers may retrain.

Resources move to more productive industries.

But in the short run:

Adjustment costs can be significant.

Therefore:

The benefits of globalisation may take time to emerge.

Cost 2: Income Inequality

Globalisation can affect different workers differently.

Suppose an advanced economy specialises in:

high-skill services.

Demand for skilled workers ↑.

Their wages ↑.

Meanwhile:

Low-skilled workers face stronger import competition.

Their wages may stagnate or jobs may disappear.

Therefore:

Income inequality can widen.

Skill Premium

The difference between wages of highly skilled and less-skilled workers may increase.

This is sometimes called a higher:

skill premium.

Globalisation can contribute to this if trade increases demand for highly skilled labour.

But Technology Also Matters

Automation and technological change can produce similar effects.

Therefore:

It is difficult to attribute all increases in inequality solely to globalisation.

Cost 3: Greater Vulnerability to External Shocks

As economies become more integrated:

Foreign recession can reduce domestic exports.

Global financial instability can affect domestic markets.

Supply-chain disruptions can reduce production.

Therefore:

Globalisation increases economic interdependence.

Singapore Example

If major trading partners experience recession:

Foreign income ↓
→ demand for Singapore exports ↓
→ X ↓
→ AD ↓
→ economic growth ↓.

Therefore:

Singapore can be exposed to external demand shocks.

Global Multiplier Effects

A recession in one major economy:

Imports ↓.

Other countries’ exports ↓.

Their incomes ↓.

Their imports ↓.

Therefore:

Economic weakness can spread internationally.

Cost 4: Supply-Chain Vulnerability

Global production networks can be efficient.

But:

They can also be fragile.

Disruptions in:

shipping;
energy;
semiconductors;
food supply

can affect production around the world.

Just-in-Time Production

Firms may hold minimal inventories to reduce costs.

This increases efficiency under normal conditions.

But:

Unexpected supply disruption can stop production quickly.

Therefore:

Efficiency can conflict with resilience.

Efficiency vs Resilience

Globalisation encourages firms to source from the lowest-cost suppliers.

However:

Concentration in a few suppliers increases risk.

Therefore:

Firms may increasingly value:

supplier diversification;
inventories;
alternative production locations.

This can raise costs but reduce vulnerability.

Cost 5: Environmental Damage

Globalisation can increase:

production;
transportation;
energy consumption.

Therefore:

Negative externalities such as:

pollution
carbon emissions

may rise.

If these external costs are not reflected in market prices:

Global production may exceed the socially efficient level.

Pollution Haven Hypothesis

Firms may potentially shift pollution-intensive activities to countries with weaker environmental regulations.

Therefore:

Production costs fall.

But:

Global environmental damage may increase.

Race to the Bottom?

Countries may fear losing investment if regulations are stricter than competitors.

This could create pressure to weaken:

environmental standards;
labour standards.

This is sometimes called a:

race to the bottom.

However, the extent varies considerably across countries and industries.

Globalisation Can Also Help the Environment

Technology can spread faster.

Trade can reduce costs of:

renewable-energy equipment;
energy-efficient machinery.

Therefore:

Globalisation can support environmental solutions as well as create environmental pressures.

Cost 6: Tax Competition

MNCs can choose among different locations.

Governments may lower corporate tax rates or provide incentives to attract investment.

This can potentially reduce tax revenue.

Therefore:

Governments may face less ability to tax mobile capital.

But Lower Taxes Can Also Attract Investment

Lower business taxation:

Expected return on investment ↑.

FDI ↑.

Therefore:

Employment and tax base may eventually increase.

Hence:

The net effect is ambiguous.

Cost 7: MNC Market Power

Large multinational firms may possess substantial market power.

They may benefit from:

global brands;
technology;
economies of scale.

Domestic firms may struggle to compete.

Therefore:

Some local firms may exit.

But Consumers May Gain

Large MNCs may provide:

lower prices
better products
more innovation.

Therefore:

The impact should be evaluated from multiple stakeholder perspectives.

Cost 8: Profit Repatriation

Foreign-owned firms generate profits.

Some profits may be sent back to the parent company’s home country.

Therefore:

Primary-income outflows ↑.

This can affect the current account.

However, This Does Not Mean FDI Is Bad

The host country may still gain through:

wages;
taxes;
supplier spending;
technology;
employment.

Therefore:

Profit repatriation is one cost within a broader cost-benefit analysis.

Cost 9: Cultural and Social Concerns

Globalisation can influence:

consumer behaviour;
labour markets;
local industries.

These effects can generate concerns about:

local identity
social adjustment.

In Economics essays, focus primarily on measurable economic consequences unless the question explicitly requires broader welfare analysis.

Globalisation and Labour Mobility

Workers may move internationally in search of:

higher wages;
employment;
better opportunities.

This can improve global labour allocation.

Benefits of Immigration to Host Country

Foreign workers can increase:

labour supply.

Therefore:

Potential output ↑.

They may fill:

skill shortages;
labour shortages.

This can reduce production bottlenecks.

Singapore and Foreign Labour

Foreign labour can complement domestic workers by filling manpower gaps.

This may enable firms to expand.

Therefore:

Potential GDP ↑.

But:

The effects depend on worker skill level and whether foreign and local labour are substitutes or complements.

If They Are Substitutes

Increase in foreign labour supply may:

reduce bargaining power or wage growth for some local workers.

Therefore:

Distributional concerns may arise.

If They Are Complements

Foreign workers may allow local skilled employees to specialise in more productive tasks.

Therefore:

Local labour productivity and wages can potentially rise.

Immigration and Aggregate Demand

More workers:

Population ↑.

Consumption ↑.

Therefore:

AD ↑.

Housing and infrastructure demand may also rise.

Congestion and Public Services

Rapid population growth can increase demand for:

housing;
transport;
healthcare;
infrastructure.

If supply cannot expand sufficiently:

Congestion ↑
housing costs ↑.

Therefore:

Non-material and material welfare can be affected.

Brain Drain

When highly skilled workers leave a developing country:

Domestic human capital ↓.

Therefore:

Potential growth may weaken.

This is called:

brain drain.

Brain Gain

Migration can also produce benefits.

Migrants may:

return with new skills;
send remittances;
create international business networks.

Therefore:

Labour mobility is not automatically harmful to source countries.

Globalisation and Foreign Direct Investment

FDI is one of the most important channels.

Consider the chain:

FDI ↑
→ investment ↑
→ AD ↑ in short run
→ capital stock ↑
→ productivity ↑
→ LRAS ↑.

Therefore:

FDI can influence both demand and supply.

Greenfield FDI

A foreign company builds a new facility.

This directly creates:

new productive capacity.

Therefore:

Employment and capital stock can rise.

Merger and Acquisition FDI

Foreign company purchases an existing domestic company.

Ownership changes.

But:

Immediate productive capacity may not increase as much as with a new facility.

Therefore:

Not all FDI has the same economic impact.

This Is a Useful Evaluation Point

Always ask:

What kind of investment?

FDI that creates:

new capital
skills
technology

may generate larger long-run benefits.

Globalisation and Financial Flows

Financial globalisation allows:

capital to move rapidly.

This can lower financing costs.

But:

It can also create volatility.

Capital Inflows

Foreign investors purchase domestic assets.

Demand for financial assets ↑.

Firms may gain easier access to finance.

Investment ↑.

Sudden Capital Outflows

If confidence changes:

Investors may withdraw funds rapidly.

This can cause:

asset price falls;
exchange-rate pressure;
financial instability.

Therefore:

Financial integration creates both opportunities and risks.

FDI vs Portfolio Investment

FDI

Generally involves lasting managerial or ownership interest.

Often relatively long term.

Portfolio investment

Purchase of financial assets such as shares and bonds.

Can potentially be more liquid and volatile.

Therefore:

Composition of capital flows matters.

Globalisation and Exchange Rates

Greater cross-border trade and capital flows increase foreign-exchange transactions.

Exports:

Demand for domestic currency ↑.

Imports:

Supply of domestic currency ↑.

Investment flows can also create large exchange-rate movements.

Globalisation and Inflation

There can be several channels.

Lower Inflation Through Imports

Access to cheaper imported goods:

Domestic prices ↓.

Foreign competition also limits domestic firms’ pricing power.

Therefore:

Inflationary pressure may fall.

Lower Production Costs

Imported inputs may be cheaper.

Therefore:

SRAS ↑.

Cost-push inflation ↓.

But Globalisation Can Import Inflation

Suppose global oil prices increase.

Import costs ↑.

Therefore:

Domestic inflation ↑.

Hence:

Global integration can both reduce and transmit inflation.

Singapore and Imported Inflation

Singapore imports many consumer goods and productive inputs.

Therefore:

Global price shocks can affect domestic inflation.

Exchange-rate policy can help moderate this imported inflation.

Globalisation and AD-AS

Globalisation can affect both curves.

Exports, investment and consumption can change.

AS

Productivity, capital, labour supply and input costs can change.

Therefore:

Globalisation should not be analysed only as an AD phenomenon.

Positive Supply-Side Effects

FDI ↑
technology ↑
competition ↑
productivity ↑.

Therefore:

LRAS shifts right.

Potential growth ↑.

Inflationary pressure may be reduced.

Negative Supply Shock

Global supply-chain disruption:

Imported input costs ↑
availability ↓.

Therefore:

SRAS shifts left.

Price level ↑
real output ↓.

This can create:

stagflationary pressure.

Globalisation and Current Account

Globalisation increases both:

exports and imports.

Therefore:

The effect on the current account is not predetermined.

A country can become more globalised while running:

a surplus

or:

a deficit.

Globalisation and Export-Led Growth

Countries can specialise in export industries.

Exports ↑
→ AD ↑
→ employment ↑.

Over time:

Scale and productivity ↑.

Therefore:

Export-led development can raise living standards.

Limitation of Export Dependence

If growth depends excessively on foreign demand:

Global recession can cause:

exports ↓ sharply.

Therefore:

Economic volatility ↑.

Diversification can reduce this vulnerability.

Globalisation and Small Open Economies

Globalisation can be particularly beneficial for small economies because:

Domestic market is limited.

International markets provide:

demand;
capital;
technology.

But small open economies are also more exposed to:

external shocks.

Singapore: Why Globalisation Matters

Singapore’s economic model is strongly connected to:

trade;
international investment;
finance;
logistics;
multinational firms;
global labour and talent flows.

Therefore:

Globalisation provides major opportunities.

But:

External vulnerability is also substantial.

Singapore Benefit 1: Access to Global Markets

The domestic population cannot support the scale of production possible through international markets.

Therefore:

Exporting allows firms to:

expand beyond the domestic market.

Singapore Benefit 2: FDI

International businesses can bring:

capital
jobs
technology.

This can strengthen Singapore’s position in higher-value industries.

Singapore Benefit 3: Employment

Foreign firms and export sectors create employment directly and indirectly.

Local suppliers may benefit.

Therefore:

Multiplier effects can occur.

Singapore Benefit 4: Consumer Welfare

Imports give households access to:

greater variety.

International competition can keep prices lower than if all goods had to be produced domestically.

Singapore Benefit 5: International Services

Globalisation creates demand for services such as:

finance;
logistics;
legal services;
consulting;
transport.

Therefore:

Singapore can specialise in internationally tradable services.

Singapore Cost 1: Global Recession

World income ↓
→ Singapore exports ↓
→ AD ↓
→ growth ↓.

Therefore:

External demand shocks can strongly influence Singapore.

Singapore Cost 2: Trade Conflict

Protectionism elsewhere can:

reduce market access.

Global investment ↓.

Supply-chain costs ↑.

Therefore:

Singapore can be affected even when it is not directly involved in the dispute.

Singapore Cost 3: Imported Inflation

Global energy or food prices ↑.

Domestic import costs ↑.

Therefore:

Inflationary pressure ↑.

Singapore Cost 4: Structural Change

Industries facing international competition may decline.

Workers need to:

reskill.

Therefore:

Structural unemployment risks can arise.

Singapore Cost 5: Inequality

Workers with skills complementary to globalisation may gain strongly.

Others may face:

wage pressure or job displacement.

Therefore:

Inclusive-growth policies become important.

Inclusive Globalisation

The challenge is not necessarily to stop globalisation.

Instead:

Governments can help spread gains more widely.

Policies include:

education;
retraining;
wage support;
social transfers;
progressive taxation.

Therefore:

Globalisation can be combined with inclusive-growth policies.

Supply-Side Policy and Globalisation

Education and training:

Skills ↑.

Workers can move into expanding industries.

Therefore:

Structural unemployment ↓.

This increases the economy’s ability to benefit from globalisation.

Infrastructure

Better:

ports
airports
digital networks

reduce business costs.

Therefore:

International competitiveness ↑.

R&D

Innovation support can help domestic firms move into:

higher-value activities.

Therefore:

The country becomes less dependent on low-cost competition.

Globalisation and Progressive Wage Policies

If globalisation generates productivity gains but wages for lower-income workers lag:

Wage-support or skills policies may help distribute gains.

However:

Wage interventions should consider productivity to avoid excessive employment costs.

Globalisation and Education

Education can influence who gains.

Higher human capital:

Workers can access higher-productivity industries.

Therefore:

Skill development can reduce the risk that globalisation widens inequality.

Globalisation and Comparative Advantage Can Change

Countries are not permanently locked into one specialisation pattern.

Investment in:

education
technology
infrastructure

can create new comparative advantages.

Therefore:

Economic development can alter the pattern of globalisation.

Globalisation and Protectionism

Governments may respond to globalisation by protecting industries.

Potential reasons:

job losses;
national security;
infant industries;
unfair competition.

But:

Protectionism can reduce many gains from globalisation.

Protectionism Chain

Tariff ↑
→ imports ↓
→ domestic producers protected.

But:

Consumer prices ↑
input costs ↑
competition ↓.

Retaliation may:

exports ↓.

Therefore:

Protectionism involves significant trade-offs.

Deglobalisation

Deglobalisation refers broadly to a reduction or slowing in international economic integration.

This may involve:

less trade;
reduced cross-border investment;
more trade barriers;
more domestic or regional production.

Is the World Necessarily Deglobalising Completely?

Not necessarily.

Globalisation can change form.

For example:

Firms may diversify supply chains rather than abandon international production.

Trade may become more regional.

Digital services may continue expanding even if some goods trade faces barriers.

Therefore:

Globalisation is not simply “on” or “off”.

Reshoring

Reshoring occurs when firms bring production back to their home country.

Possible reasons:

supply security;
automation;
trade barriers;
geopolitical risk.

Nearshoring

Nearshoring moves production closer to the final market.

This can reduce:

transport distance
supply-chain risk.

Friendshoring

Firms or governments may favour sourcing from countries considered politically or strategically reliable.

This may increase resilience.

But:

Production may no longer occur at the lowest possible cost.

Resilience Has an Opportunity Cost

Suppose the cheapest supplier produces at $10.

A more secure supplier charges $13.

Choosing the second supplier reduces disruption risk.

But:

Production costs ↑.

Therefore:

Resilience is not free.

Globalisation and Economic Security

Governments increasingly balance:

efficiency
against
security.

A fully globalised supply chain may minimise cost.

But:

A diversified chain may reduce catastrophic risk.

Therefore:

Some redundancy can be economically rational.

Does Globalisation Reduce Sovereignty?

Greater international integration can constrain policy choices.

For example:

High taxes or regulation may influence firm location.

Capital may move internationally.

Therefore:

Governments may face stronger competitive pressures.

However:

Governments still retain significant policy tools.

Globalisation and Tax Revenue

MNC activity can expand:

employment
profits
economic output.

Therefore:

tax revenue can rise.

But cross-border business structures can also make taxation more complex.

Detailed current international tax rules should be verified before using them as contemporary examples.

Globalisation and Market Failure

Globalisation does not automatically produce an efficient outcome.

Market failures can cross borders.

Examples:

climate change;
infectious disease externalities;
financial contagion.

Therefore:

International coordination may be necessary.

Global Environmental Externality

Carbon emissions in one country affect:

other countries.

Therefore:

MSC exceeds MPC internationally.

A purely national policy may not fully solve the problem.

Hence:

Global cooperation can improve effectiveness.

Global Public Goods

Some goods provide benefits across countries.

Examples include aspects of:

climate stability;
disease control;
international security.

Because countries may free ride:

Underprovision can occur.

Therefore:

Globalisation can make international cooperation more important.

Globalisation and Pandemics

Greater international mobility can accelerate spread of disease.

But global networks also allow:

rapid information sharing;
medical research collaboration;
distribution of treatments.

Therefore:

Global connectivity creates both risks and solutions.

Globalisation and Food Security

Trade allows countries with limited agricultural resources to import food.

This can improve:

availability and variety.

But:

Disruptions in global markets can create supply risks.

Therefore:

Diversified sourcing may be preferable to relying on one supplier.

Singapore Food Security Application

For an economy with scarce land:

Attempting complete food self-sufficiency has high opportunity cost.

A more efficient strategy may involve:

diversified imports
strategic reserves
selected local production.

This balances:

comparative advantage and resilience.

Globalisation and Energy Security

Energy-importing economies gain from access to global markets.

But:

Geopolitical disruptions can cause price spikes.

Therefore:

Energy diversification can reduce vulnerability.

Globalisation and Standard of Living

Globalisation can improve material standard of living through:

lower prices;
higher incomes;
more jobs;
greater variety.

But:

Non-material costs may include:

job insecurity;
pollution;
congestion.

Therefore:

GDP growth alone does not capture the complete welfare effect.

Globalisation and Inclusive Growth

Globalisation may raise average income.

But:

If gains accrue mainly to:

high-skilled workers
owners of capital,

income inequality may increase.

Therefore:

Inclusive growth requires policies that broaden access to economic opportunities.

Globalisation and Sustainable Growth

If globalisation encourages rapid resource use and pollution:

Growth may be environmentally unsustainable.

Therefore:

Government may need:

carbon taxes
regulations
green technology investment.

Globalisation and Inflation: Strong Evaluation

Globalisation may lower inflation because:

imports and competition reduce prices.

But globalisation can also transmit:

global commodity price shocks.

Therefore:

Its effect on inflation depends on:

the nature of the international shock.

Globalisation and Employment: Strong Evaluation

Globalisation does not simply:

“create jobs”

or:

“destroy jobs”.

It changes the composition of employment.

Exporting sectors may grow.

Import-competing sectors may shrink.

Therefore:

Labour mobility determines the final impact.

Globalisation and Economic Growth: Strong Evaluation

The growth effect depends on:

quality of FDI;
human capital;
infrastructure;
domestic institutions;
ability to absorb technology.

FDI alone does not guarantee productivity growth.

Absorptive Capacity

A country must have sufficient:

skills
infrastructure
institutions

to benefit fully from foreign technology.

This is called, broadly:

absorptive capacity.

If domestic firms cannot adopt advanced technology:

Spillover gains may be limited.

MNC Linkages

Benefits are larger if foreign companies create strong links with:

local firms.

Local suppliers gain:

orders
technology
expertise.

Therefore:

Domestic value added ↑.

Enclave Economy Problem

If foreign firms import most inputs, hire few local workers and repatriate most profits:

Domestic spillovers may be limited.

Therefore:

High FDI figures alone do not guarantee broad national benefits.

Globalisation and Small Firms

Small domestic firms may gain:

access to global customers.

Digital platforms can reduce entry costs.

But:

They also face stronger global competition.

Therefore:

Globalisation can simultaneously create opportunity and pressure.

Digital Globalisation

Services can increasingly cross borders digitally.

Examples include:

software;
consulting;
digital design;
online education.

Therefore:

International trade is no longer restricted mainly to physical goods.

Remote Work and Global Labour Markets

Digital technology allows some firms to hire workers internationally.

This can:

increase labour-market competition.

But it can also give workers access to:

foreign employers and higher-paying markets.

Therefore:

Distributional effects are again mixed.

Artificial Intelligence and Globalisation

AI may reduce the cost of:

translation
communication
service delivery.

Therefore:

More services can become internationally tradable.

At the same time:

AI can displace some occupations.

Therefore:

Technology and globalisation can reinforce structural change.

A-Level Worked Question

Explain how globalisation may increase economic growth.

Globalisation increases access to international markets.

Exports may rise.

Since exports are a component of AD:

X ↑
→ AD ↑
→ real GDP ↑.

Foreign direct investment may also increase.

I ↑
→ AD ↑ in the short run.

Furthermore:

FDI can increase the capital stock and facilitate technology transfer.

Labour productivity ↑.

Therefore:

LRAS shifts right.

Hence:

Globalisation can increase both actual and potential economic growth.

Evaluation

The extent depends on:

availability of skilled labour;
infrastructure;
quality of investment;
strength of external demand.

If the economy lacks the ability to absorb foreign technology:

Long-run gains may be smaller.

Worked Question: Unemployment

Explain how globalisation may cause structural unemployment.

Globalisation increases competition from foreign firms.

If foreign producers have lower costs:

Demand for domestically produced substitutes ↓.

Domestic firms reduce output.

Therefore:

Demand for labour ↓.

Workers become unemployed.

If their skills do not match those required in expanding export or technology-intensive industries:

They experience occupational immobility.

Therefore:

Structural unemployment ↑.

Evaluation

In the long run:

Retraining may improve labour mobility.

Therefore:

Structural unemployment can fall.

The effect depends on:

skills policy and adjustment speed.

Worked Question: Consumers

Explain two benefits of globalisation to consumers.

First:

Imports increase competition.

Therefore:

Prices may fall.

Consumer surplus ↑.

Second:

International trade increases product variety.

Consumers have greater choice.

Therefore:

Consumer welfare ↑.

Essay Question

“Assess whether globalisation is beneficial to an economy such as Singapore.”

A strong answer should analyse both:

growth opportunities

and:

external vulnerability.

Benefit 1: Market Access

Small domestic market means international demand is important.

Exports ↑
→ AD ↑
→ growth ↑.

Benefit 2: FDI

Capital ↑
technology ↑
productivity ↑.

Therefore:

Potential growth ↑.

Benefit 3: Consumer Welfare

Imports:

Choice ↑
prices may ↓.

Therefore:

material SOL ↑.

Benefit 4: Economies of Scale

Global markets allow firms to produce at larger scale.

Average costs ↓.

Cost 1: External Shocks

Global recession:

X ↓
→ AD ↓.

Therefore:

Growth becomes vulnerable.

Cost 2: Structural Unemployment

Import competition may cause some industries to contract.

Cost 3: Inequality

High-skilled workers may gain more than lower-skilled workers.

Cost 4: Imported Inflation

Global commodity shocks can increase domestic prices.

Judgement

For a small open economy, disengaging from globalisation could impose very high costs because domestic demand and resources are limited.

Therefore:

The more appropriate response is usually not isolation.

It is to maximise the benefits through:

skills
productivity
market diversification

while reducing vulnerabilities through:

social protection
supply-chain resilience
economic diversification.

Essay Question: Inequality

“Assess whether globalisation inevitably worsens income inequality.”

Argument

Trade and FDI can increase demand for skilled workers.

Skilled wages ↑.

Less-skilled import-competing workers may experience:

wage pressure or unemployment.

Therefore:

inequality ↑.

Counterargument

Globalisation can also create:

large numbers of jobs.

Lower-priced imports increase real purchasing power, potentially benefiting lower-income households.

Tax revenue from growth can fund:

redistribution.

Therefore:

Inequality is not an inevitable outcome.

Strong Judgement

The distributional effect depends on:

education;
labour mobility;
welfare policy;
structure of trade;
technology.

Therefore:

Domestic policy strongly influences whether globalisation is inclusive.

Essay Question: Protectionism vs Globalisation

“Assess whether increased protectionism is an appropriate response to the problems caused by globalisation.”

Argument For

Tariffs can protect:

domestic industries
employment.

Therefore:

Adjustment costs ↓ in the short run.

Counterargument

Tariffs:

prices ↑
competition ↓
input costs ↑.

Retaliation:

exports ↓.

Therefore:

Long-run growth can weaken.

Better Alternative

If problem is worker displacement:

Retraining addresses occupational immobility directly.

If problem is inequality:

Targeted redistribution may be more appropriate.

If problem is environmental:

Carbon pricing addresses the externality.

Therefore:

Policies should target the specific problem rather than globalisation generally.

Globalisation Evaluation Framework: G-L-O-B-A-L

G — Growth

Does trade and investment increase actual and potential output?

L — Labour

What happens to employment, wages and mobility?

O — Openness

How exposed is the economy to external shocks?

B — Benefits to consumers and businesses

Prices, choice, scale and productivity.

A — Adjustment and inequality

Who gains and who loses?

L — Long-run sustainability

Resilience, environment and future competitiveness.

Another Exam Framework: W-I-N-N-E-R-S

W — World markets

Market access.

I — Investment

FDI and capital formation.

N — New technology

Technology transfer.

N — New competition

Efficiency and innovation.

E — Employment effects

Job creation and structural unemployment.

R — Risks

External shocks and supply chains.

S — Social distribution

Inequality and welfare.

Policy Evaluation Framework

When globalisation causes a problem:

Identify the precise problem first.

If:

Structural unemployment

→ retraining.

If:

Inequality

→ progressive redistribution and education.

If:

Supply-chain vulnerability

→ diversification.

If:

Pollution

→ environmental policy.

If:

Weak domestic competitiveness

→ supply-side policies.

This is stronger than simply recommending protectionism.

Common Student Mistakes

Mistake 1: Defining globalisation as trade only

It also includes investment, capital, labour, technology and production networks.

Mistake 2: Saying globalisation benefits everyone

There are winners and losers.

Mistake 3: Saying foreign firms automatically benefit a country

The extent of local linkages and spillovers matters.

Mistake 4: Saying FDI always raises productive capacity equally

Greenfield investment and acquisitions can have different effects.

Mistake 5: Ignoring structural unemployment

Resources are not perfectly mobile.

Mistake 6: Blaming all inequality on globalisation

Technology and education also matter.

Mistake 7: Saying imports are harmful

Imports can lower prices and provide productive inputs.

Mistake 8: Ignoring global supply chains

Imports may be needed to produce exports.

Mistake 9: Saying globalisation always lowers inflation

It can transmit imported inflation too.

Mistake 10: Saying protectionism is the obvious solution

It can create retaliation and efficiency losses.

Mistake 11: Ignoring Singapore’s small domestic market

International access is especially important.

Mistake 12: Ignoring resilience

Maximum efficiency is not necessarily the same as minimum economic risk.

Frequently Asked Questions

What is globalisation?

The increasing integration and interdependence of economies through trade, investment, capital, technology, information and labour flows.

What causes globalisation?

Falling transport and communication costs, trade liberalisation, MNC growth, FDI and technological development.

How does globalisation increase growth?

It can increase exports, investment, productivity and technology transfer.

How does globalisation benefit consumers?

It can lower prices, increase competition and provide greater variety.

How can globalisation cause unemployment?

Import competition can cause declining domestic industries to shrink, creating structural unemployment.

How can globalisation increase inequality?

Demand may rise disproportionately for highly skilled workers and capital owners.

What is FDI?

Investment that gives a foreign firm a lasting interest in a domestic enterprise.

Why can FDI be beneficial?

It can bring capital, jobs, technology and management expertise.

Why can FDI have costs?

Profits may be repatriated and domestic firms may face stronger competition.

Why is Singapore strongly affected by globalisation?

Singapore has a small domestic market and is highly connected to international trade and investment.

Is protectionism the best response to globalisation?

Usually not automatically. The policy should target the specific problem.

Does globalisation always increase welfare?

No. The outcome depends on distribution, adjustment costs, market failures and economic resilience.

Final Takeaway

Globalisation creates stronger economic links between countries.

The core positive chain is:

Globalisation ↑

→ trade and FDI ↑
→ specialisation ↑
→ economies of scale ↑
→ competition and technology transfer ↑
→ productivity ↑
→ actual and potential growth ↑
→ potential living standards ↑.

But there is another chain:

Globalisation ↑

→ import competition and structural change ↑
→ some industries contract
→ structural unemployment may ↑
→ inequality may widen.

And:

Economic interdependence ↑

→ exposure to global recessions, supply disruptions and imported inflation ↑.

Therefore, globalisation is neither automatically beneficial nor automatically harmful.

A strong A-Level conclusion is:

Globalisation can generate substantial gains through comparative advantage, larger markets, foreign investment, competition and technology transfer. These benefits are particularly important for small open economies that cannot rely solely on domestic demand. However, the gains may be unevenly distributed, while deeper integration also increases exposure to external shocks and supply-chain disruptions. The appropriate policy response is therefore not necessarily to reverse globalisation, but to improve workers’ adaptability, strengthen domestic productivity, diversify economic links and address specific market failures so that the gains from international integration are both resilient and inclusive.
