Lecture 1 - Introduction to Economic Integration

Overview

Economic integration refers to the process by which countries remove barriers to trade, investment, and migration to form a more unified economic space. This lecture explores both the mechanisms and consequences of integration and the growing tension between global integration and economic disintegration (e.g. Brexit, US–China trade war, Covid-19 disruptions).

1. What Is Economic Integration?

Definition

Two or more countries are economically integrated when there are no barriers or restrictions on:

Trade (goods and services)
Investment (capital flows)
Migration (labour mobility)

As integration progresses, market prices for goods and factors of production tend to converge, differing only slightly due to transport or transaction costs.

Alternative definition:
“The elimination of economic frontiers between two or more economies.” – Baldwin & Wyplosz (2012)

Economic integration can be viewed as both a state (absence of barriers) and a process (removal of barriers).

2. Forms of Integration

Negative Integration

Refers to the removal of barriers that restrict cross-border economic activity.

Examples:

Customs duties or quotas on trade
Visa or work permit requirements
Taxes or restrictions on cross-border investment
Controls on financial flows

Economic rationale: Removing barriers allows for:

Larger markets → realisation of economies of scale
Increased specialisation according to comparative advantage
Greater consumer choice and product variety
Enhanced competition, improving efficiency and innovation

Positive Integration

Refers to the harmonisation and coordination of national policies between member countries.

Examples:

Common banking or data protection regulations
Coordinated environmental or fiscal policies

Rationale:

National policies often have spillover effects on other countries.
Without coordination, non-cooperative behaviour leads to inefficiency.
However, cooperation entails loss of national sovereignty, as seen in debates such as Brexit.

Note: The gains from cooperation rise as international interdependence increases through trade and capital mobility.

3. Regional vs Global Integration

Global Integration

Promoted through international institutions such as the World Trade Organization (WTO).
Encourages non-discriminatory trade and universal participation.
Broader in scope but slower to act due to divergent national interests.

Regional Integration

Involves geographically or politically aligned countries (e.g. European Union, ASEAN, CPTPP).
Can achieve deeper and faster integration due to similarity among members.
However, it may create discriminatory effects against non-members (“trade diversion”).

4. Global Institutions for Economic Integration

Institution	Established	Primary Function	Key Features
World Trade Organization (WTO)	Originated as GATT (1940s); became WTO (1995)	Regulates international trade	Enforceable dispute settlement system; negotiation rounds to reduce tariffs
International Monetary Fund (IMF)	Founded under Bretton Woods system	Oversees exchange rates and short-term capital flows	Provides financial assistance to countries facing balance-of-payments problems
World Bank	Post-WWII (for reconstruction)	Finances long-term development projects	Focus on infrastructure and poverty reduction, especially in developing economies

5. Balassa (1961) Classification of Regional Integration

Stage	Characteristics	Example
Free Trade Area (FTA)	Tariffs and quotas abolished for internal trade; external tariffs remain national	NAFTA (now USMCA)
Customs Union (CU)	Common external tariff applied to non-members	European Economic Community (1957)
Common Market (CM)	CU + free movement of labour and capital	European Single Market (1993)
Economic Union (EU)	CM + harmonisation of economic policies	European Union (EU)

Note: In practice, progression is not always linear (e.g. EU began as a customs union).

Even loose arrangements such as CPTPP require some policy harmonisation (e.g. e-commerce data protection).
Such supranational policymaking entails loss of sovereignty but ensures policy coherence.

6. Key Takeaways and Conclusions

The world economy is increasingly interdependent due to globalisation.
Integration is driven by both market forces and policy decisions (e.g. WTO, regional treaties).
Governments may trade sovereignty for efficiency gains and greater economic stability.
Regional integration can be faster but more exclusive, while global integration is slower but fairer.
Future lectures will analyse:
- Economic consequences of integration (trade creation/diversion)
- European Union as a case study of deep regional integration

Historical Development

1951 – European Coal and Steel Community (ECSC): 6 founding members (France, Germany, Italy, Belgium, Netherlands, Luxembourg)
1958 – Treaty of Rome: Established the European Economic Community (EEC)
1987 – Single European Act: Created the Single Market
1993 – Treaty of Maastricht: Formed the European Union (EU) and introduced plans for Monetary Union
2009 – Treaty of Lisbon: Institutional reforms and expanded EU competences

EU Institutions

Institution	Function
Council of Ministers	Main decision-making body; major issues decided unanimously or by qualified majority
European Commission	Proposes, implements, and monitors EU law; one Commissioner per member state
European Parliament	Elected representatives; co-decides with Council on ~80% of legislation
Court of Justice (CJEU)	Ensures uniform interpretation and enforcement of EU law

Economic integration eliminates frontiers and harmonises policies between countries, fostering larger markets and greater efficiency. Yet, it comes with challenges—particularly the trade-off between economic efficiency and national sovereignty. Understanding these dynamics is central to analysing the structure and functioning of the modern global economy.
