Globalisation and trade liberalisation

Globalisation refers to the growing interconnectedness between countries worldwide, particularly through increased international trade. This process has led to economies becoming more open, with exports and imports making up a larger share of gross domestic product (GDP) over time.

Key features of globalisation in trade

• Increased openness - Countries engage more in cross-border exchanges, boosting economic links and dependencies.
• Trade liberalisation - This involves reducing or removing barriers to trade, such as tariffs or quotas, to promote freer movement of goods and services.

Trade liberalisation can occur through various agreements, either between specific groups of countries or on a global scale via organisations like the World Trade Organization (WTO).

The World Trade Organization and preferential trade agreements

The World Trade Organization (WTO) is an international body that oversees global trade rules, with 164 member countries accounting for about 98% of world trade. It promotes multilateral agreements to reduce trade barriers across all members.

Role of the WTO

• Facilitates negotiations to lower tariffs and resolve trade disputes.
• Aims for broad, inclusive trade liberalisation that benefits all members.

However, progress through the WTO can be slow, leading to the rise of preferential trade agreements, which reduce barriers between specific countries on selected goods and services.

Types of preferential trade agreements

• Bilateral agreements - Arrangements between two countries to lower trade barriers.
• Regional agreements - Deals among multiple neighbouring countries, often forming regional trading blocs.
• Plurilateral agreements - Involves several countries that may not be geographically close.
• Multilateral agreements - Global pacts involving all WTO members.

By 2020, there were 320 regional trade agreements in operation, an increase from 294 in 2019. These have grown due to the speed of negotiations and the push for closer economic ties.

Forms of economic integration in trading blocs

Trading blocs represent different levels of economic integration, starting from basic free trade and progressing to deeper unions. Each stage builds on the previous one, removing more barriers.

Stages of economic integration

• Free trade area (FTA) - Countries eliminate internal trade barriers but keep their own tariffs on non-members. Rules of origin are needed to stop non-members routing goods through the lowest-tariff member.
• Customs union - An FTA plus a common external tariff and unified trade policy towards outsiders.
• Common market - A customs union that also permits free movement of labour and capital across borders.
• Economic union - Members align their economic policies, including macroeconomic and regulatory rules.
• Monetary union - Countries share a single currency and a central bank to manage it.

These forms allow for progressive integration, with regional blocs often forming faster than global agreements.

Static and dynamic effects of trading blocs

Trading blocs have both immediate (static) and longer-term (dynamic) impacts on member economies. Static effects, based on economist Jacob Viner's 1950 analysis, focus on efficiency changes in trade patterns.

Static effects of trading blocs

• Trade creation - Occurs when lower barriers lead to imports from efficient member countries replacing less efficient domestic production, improving overall efficiency.
• Trade diversion - Happens when imports switch from a low-cost non-member to a higher-cost member due to preferential tariffs, potentially reducing efficiency.

Dynamic effects arise over time as trading blocs mature

• Larger markets attract more investment, speeding up economic growth.
• Heightened competition drives down prices and boosts efficiency.
• Consumers gain access to a wider range of products.
• Free labour movement creates more job opportunities.
• Technology spreads faster across open borders.
• Blocs gain stronger negotiating power in global talks.
• Prosperity fosters political stability.
• Negotiations are simpler with fewer parties than in the WTO.
• Deeper ties extend to areas like investment and intellectual property.
• Economies of scale enhance competitiveness for firms.

Advantages and disadvantages of trading blocs

While trading blocs offer significant benefits, they also present challenges, particularly in relation to global trade systems and internal dynamics.

Advantages of trading blocs

Disadvantages of trading blocs

• Undermining global efforts - May act as "stumbling blocks" to broader WTO liberalisation.
• Power imbalances - Larger economies can dominate negotiations with smaller ones.
• Spaghetti bowl effect - Overlapping agreements create complex tariffs and rules, raising business costs.
• Loss of sovereignty - Countries surrender some control over policies.
• Lobbying influences - Producers may push for blocs to gain from trade diversion, benefiting themselves at the expense of overall efficiency.
