3. Introduction
Economic integration refers to the commercial policy of discriminatively reducing or eliminating barriers only among the nations joining together.

4. Preferential trade arrangements
Introduction
Preferential trade arrangements
Provide lower barriers to trade among participating nations than on trade with non-member nations.
The loosest form of economic integration.
Example: British Commonwealth Preference Scheme, established in 1932 between the United Kingdom and members of the British Empire.
Salvatore: International Economics, 11th Edition © 2013 John Wiley & Sons, Inc.

5. Introduction Free trade areas
Removes all barriers to trade among members, but each nation retains its own barriers to trade with non-members.
Examples:
European Free Trade Association (EFTA), 1960, between United Kingdom, Austria, Denmark, Norway, Portugal, Sweden and Switzerland
North American Free Trade Agreement (NAFTA), 1993, between the United States, Canada and Mexico
Salvatore: International Economics, 11th Edition © 2013 John Wiley & Sons, Inc.

6. Introduction Customs union
Removes all barriers to trade among members and harmonizes trade policies toward the rest of the world.
Examples:
European Union (EU), or European Common Market, 1957, between West Germany, France, Italy, Belgium, the Netherlands, and Luxembourg.
Zollverein, 1834, between large number of sovereign German states

7. Introduction Common market
Removes all barriers to trade among members, harmonizes trade policies toward the rest of the world, and allows free movement of labor and capital among member nations.
Example:
European Union (EU) achieved common market status in 1993.

8. Introduction Economic union
Removes all barriers to trade among members, harmonizes trade policies towards the rest of the world, allows free movement of labor and capital among member nations, and unifies monetary and fiscal policies of members.
Most advanced type of economic integration.
Examples:
Benelux, formed after World War II between Belgium, the Netherlands and Luxembourg

9. Duty free zones (free economic zones)
Introduction

10. Trade-Creating Customs Unions
Trade creation occurs when domestic production in a member nation is replaced by lower-cost imports from another member nation.
Leads to increased welfare for members as nations specialize in comparative advantages.
Leads to increased welfare for non-members as increased real income spills over into increased imports from rest of the world.

12. Trade-Diverting Customs Unions
Trade diversion occurs when lower-cost imports from non-members are replaced by higher cost imports from members.
By itself, trade diversion lowers welfare as it shifts resources away from comparative advantages.
Trade diverting customs union also results in trade creation. Change in welfare depends on relative magnitude of creation and diversion.

14. The Theory of the Second Best and Other Static Welfare Effects of Customs Unions
It was once believed that any movement toward freer trade would increase welfare, so formation of a customs union would necessarily result in increased welfare for members and non- members.
In 1950, Viner showed that formation of a customs union could increase or reduce welfare, depending on the circumstances under which it takes place.

15. Theory of the Second Best
The Theory of the Second Best and Other Static Welfare Effects of Customs Unions
Theory of the Second Best
If all conditions required to maximize welfare cannot be satisfied, trying to satisfy as many conditions as possible does not necessarily or usually lead to the second-best position.
Salvatore: International Economics, 11th Edition © 2013 John Wiley & Sons, Inc.

16. Conditions More Likely to Lead to Increased Welfare
The Theory of the Second Best and Other Static Welfare Effects of Customs Unions
Conditions More Likely to Lead to Increased Welfare
Higher pre-union trade barriers of member nations.
Lower customs union’s trade barriers with non-members.
Greater number of nations forming customs union, and the larger their size.
Salvatore: International Economics, 11th Edition © 2013 John Wiley & Sons, Inc.

17. Conditions More Likely to Lead to Increased Welfare
The Theory of the Second Best and Other Static Welfare Effects of Customs Unions
Conditions More Likely to Lead to Increased Welfare
More competitive rather than complementary economies of member nations.
Closer geographical proximity of member nations.
Greater pre-union trade and economic relationship among potential member nations.
Salvatore: International Economics, 11th Edition © 2013 John Wiley & Sons, Inc.

18. Other Static Effects of Customs Unions
The Theory of the Second Best and Other Static Welfare Effects of Customs Unions
Other Static Effects of Customs Unions
Administration savings from elimination of customs officers, border patrols, and others.
Reduction in demand for imports from and supply of exports to rest of the world will likely lead to improvement in collective terms of trade of member nations.
By acting as a single unit, customs union will likely have more bargaining power than members separately.
Salvatore: International Economics, 11th Edition © 2013 John Wiley & Sons, Inc.

19. Dynamic Benefits from Customs Unions
Dynamic Benefits of Customs Unions
Increased competition, leading to greater efficiencies and technological improvements.
Economies of scale from the enlarged market.
Stimulus of investment to take advantage of enlarged market, and to meet increased competition.
Better utilization of community resources as labor and capital move freely (assumes common market).
