There are several stages in the process of economic integration, from a very loose association of countries in a preferential trade area, to complete economic integration, where the economies of member countries are completely integrated.
A regional trading bloc is a group of countries within a geographical region that protect themselves from imports from non-members in other geographical regions, and who look to trade more with each other. Regional trading blocs increasingly shape the pattern of world trade - a phenomenon often referred to as regionalism.
Stages of integration
Preferential Trade Area
Preferential Trade Areas (PTAs) exist when
countries within a geographical region agree to reduce or eliminate
tariff barriers on selected goods
imported from other members of the area. This is often the first small
step towards the creation of a trading bloc. Agreements may be made
between two countries (bi-lateral), or several countries
Agreements may be made between two countries (bi-lateral), or several countries (multi-lateral).
Free Trade Area
Free Trade Areas (FTAs) are created when two or more countries in a region agree to reduce or eliminate barriers to trade on all goods coming from other members. The North Atlantic Free Trade Agreement (NAFTA) is an example of such a free trade area, and includes the USA, Canada, and Mexico.
A customs union involves the removal of tariff barriers between members, plus the acceptance of a common (unified) external tariff against non-members. This means that members may negotiate as a single bloc with 3rd parties, such as with other trading blocs, or with the WTO.
A common market is the first significant step towards full economic integration, and occurs when member countries trade freely in all economic resources – not just tangible goods. This means that all barriers to trade in goods, services, capital, and labour are removed. In addition, as well as removing tariffs, non-tariff barriers are also reduced and eliminated. For a common market to be successful there must also be a significant level of harmonisation of micro-economic policies, and common rules regarding monopoly power and other anti-competitive practices. There may also be common policies affecting key industries, such as the Common Agricultural Policy (CAP) and Common Fisheries Policy (CFP) of the European Single Market (ESM).
Economic Union is a term applied to a trading bloc that has both a common market between members, and a common trade policy towards non-members, but where members are free to pursue independent macro-economic policies.
Monetary union is the first major step towards macro-economic integration, and enables economies to converge even more closely. Monetary union involves scrapping individual currencies, and adopting a single, shared currency, such as the Euro for the Euro-16 countries, and the East Caribbean Dollar for 11 islands in the East Caribbean. This means that there is a common exchange rate, a common monetary policy, including interest rates and the regulation of the quantity of money, and a single central bank, such as the European Central Bank or the East Caribbean Central Bank.
A fiscal union is an agreement to harmonise tax rates, to establish common levels of public sector spending and borrowing, and jointly agree national budget deficits or surpluses. The majority of EU states agreed a fiscal compact in early 2012, which is a less binding version of a full fiscal union.
Economic and Monetary Union
Economic and Monetary Union (EMU) is a key stage towards compete integration, and involves a single economic market, a common trade policy, a single currency and a common monetary policy.
Complete Economic Integration
Complete economic integration involves a single economic market, a common trade policy, a single currency, a common monetary policy (EMU) together with a single fiscal policy, tax and benefit rates – in short, complete harmonisation of all policies, rates, and economic trade rules.
