EconomicEconomic IntegrationIntegration TheoryTheory andand PracticePractice DefinitionDefinition ofof economiceconomic integrationintegration The combination of several national economies into a larger territorial unit. It implies the elimination of economic boarders between countries. Economic borders : any obstacle which limits the mobility of goods services and factors of production between countries. DefinitionDefinition ofof economiceconomic integrationintegration • Jan Tinbergen: all processes of economic integration include two aspects: – Negative integration: the elimination of obstacles. – Positive integration: harmonization, coordination of existing instruments. Number of regional trade agreements, 1948-2002 Source: WTO (2003) LevelsLevels ofof economiceconomic integrationintegration • There are several levels of economic integration: – A. Free trade area – B. Customs union – C. Common or single market – D.

TradeTrade diversion.diversion. • Replace imports from cheaper 3rd countries by more expensive imports from members of the customs union. • The customs union has a positive welfare effect if trade creation > trade diversion. This will tend to happen when: – The more inclusive the customs union (fewer 3rd countries). – The higher the initial tariff eliminated by the creation of the customs union (P F-P G in the following figure) – The smaller the difference between the price which emerges from the customs union and the price which could be had from importing from the most efficient producer who by definition is a 3rd country.

BenefitsBenefits ofof aa commoncommon marketmarket • Free movement of K and L: – More efficient allocation of resources – Convergenece of wages and capital incomes within the CM. – But: • K moves easier than L (transport and cultural costs). Capital movements in the Common Market • M&A activity is high in EU. • much M&A is mergers within member state. – about 55% ‘domestic.’ – Remaining 45% split between: • one is non-EU firm (24%), • one firm was located in another EU nation (15%), • counterparty’s nationality was not identified (6%). 23 Capital movements in the Common Market • Distribution of M&A quite varied: – Big 3’s share M&As much lower than share M&A activity by nation, 1991-2002 of the EU GDP.
