What is economic integration?

· Economic integration = countries becoming more economically linked by reducing trade barriers and, in some cases, coordinating factor mobility, policies or a shared currency.
· It usually aims to increase efficiency, market size, competition and cooperation.
· Integration can deepen from preferential agreements to more advanced forms such as a common market and monetary union.
· Key exam idea: as integration deepens, potential benefits rise, but so can loss of sovereignty and policy constraints.

Preferential trade agreements

· Preferential trade agreement (PTA) = countries give each other better trading terms than non-members.
· Bilateral agreement = between two countries.
· Regional agreement = between countries in the same region or bloc.
· Multilateral agreement = involves many countries; in the syllabus this includes the World Trade Organization (WTO) framework for global trade rules.
· Exam focus: be able to identify the type of agreement and explain how it may change trade flows, market access and negotiating power.

Trading blocs: know the difference

· Trading bloc = a group of countries that reduce barriers to trade between themselves.
· Free trade area / free trade agreement: members remove tariffs and quotas between themselves, but each country keeps its own external trade policy against non-members.
· Customs union: a free trade area plus a common external tariff (CET) against non-members.
· Common market: a customs union plus free movement of labour and other factors of production.
· Easy way to compare:
· FTA = free internal trade only
· Customs union = free internal trade + common external tariff
· Common market = customs union + factor mobility
· Typical exam move: explain how each deeper stage increases integration and usually increases the need for policy coordination.

This diagram helps distinguish overlapping European institutions such as the EU customs union, eurozone and related groupings. It is useful for avoiding the common exam mistake of treating all European integration as identical. Source

This map shows the members and associated participants in the EU Customs Union. It is a strong real-world example for explaining what a customs union looks like in practice. Source

Advantages of trading blocs

· Greater access to markets allows firms to sell to more consumers and may generate economies of scale.
· Larger markets can increase competition, pushing firms to become more efficient.
· In a common market, freedom of labour movement can increase employment opportunities and help reduce labour shortages.
· Membership can strengthen a country’s bargaining power in multilateral negotiations because countries negotiate as part of a larger bloc.
· Integration may increase political stability and cooperation between member states.
· Good evaluative point: benefits are often unevenly distributed, so overall gains in efficiency may not guarantee equity.

Disadvantages of trading blocs

· There may be a loss of sovereignty, especially when members must follow common rules or common external trade policies.
· Large blocs can create a challenge to multilateral trade negotiations if regional interests clash with global agreement.
· Some domestic firms may face stronger competition and lose market share.
· Benefits may be concentrated in stronger regions, industries or workers, increasing inequality between groups.
· Evaluative point: the bigger and deeper the bloc, the larger the possible gains from integration, but also the greater the possible political tension and policy trade-offs.

Monetary union

· Monetary union = two or more countries share a common currency and a common or closely coordinated monetary policy.
· Example: the euro area.
· Monetary union goes beyond trade integration because member countries no longer control their own interest rates or exchange rate policy.
· This can support trade and investment inside the bloc, but it also reduces national policy flexibility.

The World Trade Organization (WTO)

· The WTO is the main international organization governing global trade rules.
· Objectives/functions:
· promote freer trade through agreed rules
· provide a forum for trade negotiations
· help settle trade disputes
· monitor trade agreements and members’ trade policies
· The WTO supports a more multilateral approach rather than only regional or bilateral deals.
· Factors affecting the WTO’s influence:
· difficulty reaching agreement, especially on services and primary products
· unequal bargaining power between stronger and weaker member countries
· Strong evaluation point: the WTO can promote rules-based trade, but progress is often slow because members have conflicting interests.

High-scoring evaluation points

· Trading blocs can increase efficiency and economic well-being, but gains are not always equally shared.
· Deeper integration may improve trade, labour mobility and cooperation, but often involves more loss of sovereignty.
· A bloc is more likely to be beneficial when it creates more trade creation than trade diversion.
· Monetary union can work better when member economies are similar or when there is strong labour mobility and policy coordination.
· The rise of regional blocs can support trade, but it may also make multilateral negotiations harder.
