Brother Bryson Marriott School

1. Economic Integration • Brother Bryson • Marriott School I. Significance and Substance

2. Integration and World History • Jean Monet, Robert Schumann, Walter Hallstein and others dreamed, at the end of WWII and centuries of war in Europe, of a new era. • What if Europeans quit shooting at each other and begin to focus more on doing business with each other. • Trade and investment might make old political enemies new business partners

3. Integration and World History • If business went well, perhaps European nations could become more united. • Could the day come when there would be a United States of Europe, with all states living in harmony and peace? • So the effort began in 1950 with the establishment of the European Coal and Steel Community. See p. 221, Pugel and Lindert, for EU development

4. Economic Integration 1.The basic concept:Freedom for many economic agents to buy and sell beyond national frontiers

5. Economic Integration This freedom is often retracted by policymakers, who in the pursuit of special interests construct trade barriers opposed to the general, social interest.

6. Economic Integration Originally, tariffs were imposed to raise tariff revenues. Later, legislatures were approached for politically expedient protection of domestic industry.

7. Once such barriers are in place, they are not easily removed. Integration means removing barriers strictly on a regional basis. Integration is not a return to free trade.

12. Types of “capitalist” integration: • A. The free trade area. • A set of partners in a given region. • Members eliminate trade barriers among themselves • each member maintains its own set of (usually tariff) barriers against imports from non-member countries

13. Integration Types • B. Customs union. • Regional membership • Members eliminate barriers among themselves • But also establish a common external tariff

14. Integration Types C. Common Market. To the customs union tariff arrangements, this form adds full freedom of movement to production factors

15. Integration Types • D. Economic Union. • Like customs union, plus… • harmonization of member countries’ economic (especially monetary) policies.

16. Economic Integration III. Integration Theory

17. Integration Theory We will limit our analysis to the customs union. Consider a protected industry before the customs union is formed. . . We return to the simple theory of a tariff, imposed as a tax added on to the world price…

18. Integration Theory $ S Pt = the domestic price after the imposition of tariffs. Pw = the world market price, or what our citizens would pay if industry were not protected. A Pt B Pw D X 0

19. Integration Theory The domestic market price (intersection of S and D) which would hold without any international trade is substantially higher than the world market price. $ S The domestic price Pt The market shown obviously belongs to a country with a comparative disadvantage in this industry. Pw D X 0

20. Integration Theory This country finds the world price too damaging to domestic producers. $ S At the world price, domestic firms produce 0q1 and enjoy revenues Pw(ql) A B Pw D From world producers, we import ql-M1, and their revenues are Pw(ql-M1). X 0 q1 M1

21. Pt Integration Theory The consumer surplus enjoyed before the tariff… is reduced when the tariff is imposed. Losses are the strip. $ S A B Pw D X 0 q1 q2 M2 M1

22. Pt Integration Theory Naturally, with the higher, tariff price, the producer gains less than the consumer loses. $ S The producer begins with this producer surplus… And when the price rises and his output increases to q2, producer surplus increases also. A B Pw D X 0 q1 q2 M2 M1

23. Pt Integration Theory After the tariff is imposed, our total imports fall from q1M1… $ S to q2-M2. A B Pw D X 0 q1 q2 M2 M1

24. Forming the Customs Union Consider the same industry. $ Partner countries are now permitted to send their goods to us without tariffs. But their price, Pcp, although lower than our domestic price, is higher than the world market price. S E Pt Pcp F Pw D X 0 M’ M’ M M

25. Forming the Customs Union Before the customs union, imports were MM. They were limited, because price Pt included the tariff . These imports came from more efficient producers in world markets, who would have been willing to sell at Pw. $ S E Pt a b c' d F Pcp c Pw D X 0 M' M M M'

26. Economic Integration IV. Trade Creation and Trade Diversion

27. Integration Phenomenon I Integration has two important phenomena. The first: TRADE CREATION $ S As the price falls from Pt to Pcp, total imports increase from MM… to M'M' E Pt F Pcp D X 0 M' M' M M

28. Note: the tariff is still in effect, so the price is still Pt for countries outside this community. But at this high price, hardly anyone in the country is willing to purchase from this general world market, even though its producers are more effective than those of our country or of our customs union partners. Pcp is not a price which incorporates a tariff. It is simply the price of our integration partners. They can produce more cheaply than we can at Pt, but there commodities are more costly to produce than the best producers in the world market.

29. Integration's lower consumer price and consumer surplus • As the price went down from Pt to Pcp there is a world net welfare gain (of consumer surplus) of b and d. • The area e represents a loss of producer surplus, but this is offset by an equal consumer surplus gain. • c’ is consumer surplus which was formerly (at Pt) tariff revenues. $ S E Pt e a b c' d F Pcp c Pw D X 0 M' M M M'

30. INTEGRATION PHENOMENON II: TRADE DIVERSION Pcp increases imports to M'M‘. Before integration, at Pt,… all imports, MM, came from world trade. None of it came from partner countries at Pt. $ S Pt Pcp Pw D X 0 M' M M M'

31. The Second Integration Phenomenon: Trade Diversion • After the customs union, all trade comes from new partner countries. • Tariff barriers remain in place for non-members. • Tariffs divert trade from them to our new partners. $ S E Pt F Pcp Pw D X 0 M' M M M'

32. Trade Diversion Costs • Trade diversion brings a deadweight loss of c. • This represents the increased cost of getting MM produced in the less efficient partner countries. • At Pt, c was collected as tariff revenue (along with c'). $ S E Pt c' F Pcp c Pw D X 0 M' M M' M

33. Economic Integration V. The Net Benefits of Integration

34. Net Costs of Integration • After economic integration, import costs are in blue. • We lose the former tariff revenues, c. • Our consumers gain a, b, c’ and d. • These areas are increased CS, shown in red. $ $ $ S a b c' d c D X 0 0 0

35. INTEGRATION: Bottom Line • In summary: the custom union brings • a gain of a and b, • a loss of c, the sum paid for higher partner countries production costs. At Pt, c was tariff revenues. P a b Pcp c Q 0

36. INTEGRATION: Bottom Line • The elasticities of S and D (the slopes of the curves). • (Elastic or flat curves imply greater trade creation.) The relative sizes of these gains depend on: P Pt Pcp Imports 0 Q

37. INTEGRATION: Bottom Line The relative sizes of these gains depend on: 1. elasticities, the “flatness” of the curves. P Imports Imports Q

38. INTEGRATION: Bottom Line The relative sizes of these gains depend on: 1. elasticities, the “flatness” of the curves, 2. The cost differences between domestic partners and world producers. Gains are greatest when the difference is great between home and partner and small between partner and world. (The partner country is much more efficient than we are, and nearly as efficient as the world’s best producers.)

39. Integration: Bottom Line Gains are greatest when the difference is • small between partner and world. • great between partner countries and us. c c

40. Economic Integration The dynamic effects of customs unions • The static effects of customs unions (as we have seen: a + b - c) may be small as a fraction of the total national income, • but dynamic effects are very important.

41. Dynamic Integration Effects The dynamic effects of customs unions include: 1. Economies of scale (similar to having a large internal market). To serve a large market, firms can begin to expand, if they have economies of scale, the very process of expansion causes their unit production costs to fall, increasing their competitiveness in global and domestic markets.

42. Dynamic Integration Effects The dynamic effects of customs unions include: • 2. Stimulus of competition • Large companies now less protected must compete • Small companies must merge, combine, become efficient

43. Dynamic Integration Effects The dynamic effects of customs unions include: • 3. Stimulus to invest. • to take advantage of export opportunities, or • to meet new import competition.
