Globalisation: Definition and Causes

Globalisation is not a single event but a process driven by specific factors. Understanding these causes helps explain why international trade has expanded significantly in recent decades.

Building on the definition: Globalisation is not just about trade; it also involves the flow of capital and ideas. However, for this topic, we focus heavily on the economic aspects: trade flows and MNC activity.

Globalisation

Globalisation is the increasing integration and interdependence of the world's economies, cultures, and populations. It is driven by cross-border trade in goods and services, technology, and flows of investment, people, and information.

Causes of Changes in Globalisation

The expansion of globalisation is primarily driven by four key factors:

Factor	Explanation
Reduction in Trade Restrictions	Governments have lowered tariffs and removed quotas through agreements like the WTO. This makes it easier and cheaper to trade across borders.
Lower Transport Costs	Improvements in shipping (containerisation) and aviation have drastically reduced the cost of moving goods, making international trade more profitable.
Lower Communication Costs	The internet and digital technology allow instant communication and coordination of global supply chains, reducing transaction costs for businesses.
Movement of Multinational Companies (MNCs)	MNCs establish operations in multiple countries to access cheaper labour, new markets, or resources, directly linking economies together.

Effects of Globalisation

Globalisation has profound effects on various economic and social variables. These effects are often mixed, creating winners and losers.

Area	Positive Effects	Negative Effects
International Trade	Increased volume of trade; countries specialise according to comparative advantage.	Over-reliance on imports for essential goods (e.g., food security risks).
Competition	Consumers benefit from lower prices and greater variety. Firms are forced to innovate.	Domestic firms may be driven out of business if they cannot compete with efficient foreign producers.
Income Distribution	Wealth is generated in developing countries, lifting people out of poverty.	In developed countries, low-skilled workers may face wage stagnation or job losses due to offshoring. Inequality may increase within countries.
Economic Development	MNC investment brings capital and technology to developing nations (host countries).	Profits may be repatriated to home countries rather than reinvested locally. Resource depletion in host countries.
Environment	Transfer of green technology to developing nations.	Increased transport emissions. 'Race to the bottom' where MNCs locate in countries with weak environmental regulations.
Migration	Labour mobility allows workers to move to areas with higher wages.	Brain drain (skilled workers leaving developing countries). Social tensions in host countries.

Multinational Companies (MNCs)

MNCs are firms that operate in more than one country. They have a headquarters in the home country and production/sales offices in host countries.

Stakeholder	Advantages	Disadvantages
Host Country (where factory is)	Capital Inflow: FDI brings investment. - Employment: Creates jobs, reducing unemployment. - Technology Transfer: Workers gain skills and access to new tech. - Tax Revenue: Government collects taxes from MNC profits.	Profit Repatriation: Profits are sent back to the home country, not reinvested locally. - Market Dominance: May drive local firms out of business (monopoly power). - Exploitation: May pay low wages or use poor working conditions. - Environmental Damage: May exploit lax regulations.
Home Country (HQ location)	Higher Profits: Access to cheaper inputs and larger markets. - Export Growth: MNCs often export back home or globally.	Job Losses: Manufacturing jobs may move abroad (offshoring). - Trade Deficit: May import more from host countries than it exports.

Evaluating MNC Impact

When to use: When asked to 'evaluate' or 'discuss' the impact of MNCs on a host country.

Why examiners accept this: Examiners look for balanced analysis. Do not just list pros and cons. You must weigh them. For example, acknowledge that while MNCs create jobs, they may also suppress wages if there is no unionisation.

Example phrase: 'While the inflow of foreign direct investment (FDI) boosts GDP in the short term, the long-term benefit depends on whether technology transfer occurs and if profits are reinvested locally rather than repatriated.'

Trade Restrictions: Types and Reasons

Governments often intervene in free trade using protectionist policies. These are known as trade restrictions or protectionism.

Types of Trade Restrictions

Type of Restriction	Definition and Mechanism
Tariff	A tax imposed on imported goods. This raises the price of imports, making domestic goods relatively cheaper. It also generates tax revenue for the government.
Import Quota	A physical limit on the quantity of a specific good that can be imported. This restricts supply, driving up the price of the imported good.
Subsidy	A payment from the government to domestic producers. This lowers their costs, allowing them to sell at lower prices or compete more effectively against imports.
Embargo	A complete ban on trade with a specific country or on a specific good. It is the most severe form of restriction.

⚠︎ Confusing Quotas and Tariffs

Common Error: Students often think that reducing an import quota increases expenditure on imports.

Correct Understanding: Reducing a quota means allowing fewer imports. This restricts supply and typically leads to higher prices for the remaining imported goods, but the total quantity traded decreases. Conversely, removing a tariff lowers the price, which may increase the quantity demanded.

Reasons for Trade Restrictions

Governments justify protectionism using several arguments:

Reason	Explanation
Protect Infant Industries	New industries in developing countries need protection from established foreign competitors until they can achieve economies of scale and become competitive.
Protect Declining Industries	To prevent sudden job losses and social unrest in sectors that are no longer competitive globally (e.g., traditional manufacturing).
Protect Strategic Industries	To ensure self-sufficiency in essential goods like food, energy, or defence equipment, so the country is not dependent on foreign suppliers during a crisis.
Avoid Dumping	To protect domestic firms from dumping, where MNCs sell goods below cost to drive competitors out of the market and gain monopoly power.
Reduce Current Account Deficit	By restricting imports, a country can reduce its import bill, improving the balance of payments (current account).
Raise Tax Revenue	Tariffs provide a source of government revenue, which is particularly useful in developing countries with weak domestic tax collection systems.
Restrict Import of Demerit Goods	Governments use tariffs or quotas to raise the price of goods with negative externalities (e.g., tobacco, alcohol) to reduce consumption and correct market failure.
Promote Environmental Sustainability	To prevent 'pollution havens' where MNCs might exploit weak environmental laws in host countries. Restrictions can ensure higher environmental standards are met.

Explaining Infant Industry Protection

When to use: When asked to explain the rationale behind protecting new industries.

Why examiners accept this: You must link protection to long-term competitiveness. Simply saying 'to help them' is insufficient. You need to mention economies of scale or learning curves.

Example phrase: 'Protecting infant industries allows them to build capacity and achieve economies of scale, which lowers their long-run average costs, enabling them to compete with established foreign rivals in the future.'

Consequences of Trade Restrictions

While protectionism has political and strategic benefits, it creates economic inefficiencies.

Aspect	Impact
Deadweight Loss (Allocative Inefficiency)	Tariffs and quotas create deadweight loss. This occurs because: 1. Production Distortion: Domestic production shifts from efficient foreign producers to less efficient domestic producers. 2. Consumption Distortion: Higher prices reduce consumption below the optimal level, meaning mutually beneficial trades do not occur.
Impact on Home Country	Pros: Protects specific jobs and industries. - Cons: Consumers pay higher prices. Downstream industries (using imported inputs) face higher costs. Risk of retaliation from trading partners.
Impact on Trading Partners	Retaliatory tariffs may be imposed, leading to a trade war. - Exporting countries lose market access, potentially causing unemployment in their export sectors.
Advantages of Free Trade (vs. Restrictions)	Free trade allows countries to specialise according to comparative advantage, leading to lower prices, greater variety for consumers, and more efficient global resource allocation.

Past Paper Style Questions

Discuss whether or not imposing tariffs on imports will increase a country’s output. [8]

Arguments for:
- Tariffs raise the price of imports, reducing demand for foreign goods.
- Consumers switch to domestically produced substitutes (import substitution).
- Net exports (X-M) increase, raising Aggregate Demand (AD).
- Higher AD encourages firms to increase output and employment in the short run.

Arguments against:
- If domestic industries are inefficient, they may not be able to meet the increased demand, leading to shortages.
- Tariffs on raw materials increase costs for downstream industries, reducing their competitiveness.
- Retaliation from trading partners may reduce exports, offsetting gains in output.

Conclusion: Output may rise temporarily if the economy has spare capacity, but long-term efficiency is reduced due to protection of uncompetitive firms.

Analyse how a government subsidy could help protect an infant industry against foreign competition. [6]

A subsidy is a payment from the government to domestic producers.
- It lowers the firm's average costs of production.
- This allows the firm to sell at a lower price than foreign competitors, or reinvest the savings into technology and skilled labour.
- Over time, as output increases, the firm may achieve economies of scale, further lowering average costs.
- Eventually, the industry becomes competitive without needing subsidies.

Compare why a government may protect its country’s industries from foreign competition. [6]

Infant Industries: Protection allows new firms to grow and achieve economies of scale before facing global competition.
- Strategic Industries: Protection ensures self-sufficiency in essential goods (e.g., food, defence) to avoid dependency on unstable foreign suppliers.
- Declining Industries: Protection prevents sudden job losses and social unrest in sectors that are no longer globally competitive.
