1. International trade Today: Winners and losers of various international trade policies

2. Today: More on international trade Addressing concerns about trade Review of comparative advantage Examining consumption possibilities Without trade With trade Supply and demand analysis of trade Tariffs and Quotas “Outsourcing”

3. Addressing concerns about trade “A majority of Americans, including 60 percent of Republicans, now believe free trade is bad for the U.S. economy, according to recent NBC News-Wall Street Journal polls.” (Source: “Trade jitters, anti-China sentiment rouse US voters,” Reuters, Nov. 14, 2007) Why do so many Americans have this opinion about trade?

4. Trade has costs and benefits When another country can produce goods lower than in the United States, two things happen Jobs are lost in the United States Consumers pay lower prices for the good that is now imported The news media usually focuses on the jobs issue more than about prices

5. Why is media coverage skewed? Any job lost seriously deteriorates the quality of life of an individual Most people don’t care to read headlines advertising “The price of rice goes down by two cents per pound” However, small gains on many products lead to substantial increases in the purchasing power of the dollar

6. Suppose there is protectionism elsewhere The United States is a leading exporter of fresh fruit (see on-line reading list for source) Suppose that other countries outlawed the import of fresh fruit US jobs lost Decrease in price of fruit in the US Increase in the price of fruit in other countries

7. Another issue: Lead in toys Recently, many toys manufactured in China have been recalled due to unsafe levels of lead This has raised concerns about the viability of toy exports China will stop exporting toys if the world does not view the toys as safe enough, given the price

8. Monitoring is costly Monitoring toys for lead is costly, adding to the cost of toys purchased However, testing costs may be small relative to the additional revenues that can be generated if “safe toys” can be guaranteed

9. Another example: American cars Over the last 30 years, American cars have often been looked at as “inferior” compared to some foreign models With competition from trade, domestic car producers must keep costs down and quality up in order to successfully sell cars in the domestic market The same thing goes for foreign toys If quality control standards are not maintained abroad, people will buy their toys domestically

10. Trade issues There are many other issues that are related to trade If you would like an in-depth analysis of trade, you can enroll in a class that deals with trade Today, we will talk about the basic issues of trade, and who the winners and losers are

11. Review of comparative advantage Recall the principle of comparative advantage “Everyone does best when each person (or each country) concentrates on the activities for which his or her opportunity cost is lowest.” (F/B p. 39) Today, we will apply this concept on a countrywide scale

12. Comparative advantage: Same numbers, different names Productivity in pizza production Productivity in salad production United States 20 pizzas cooked per hour 10 salads made per hour Chile16 pizzas cooked per hour 4 salads made per hour

13. Comparative advantage To find comparative advantage for each person, find the lowest number in each column Opportunity cost of cooking a pizza Opportunity cost of making a salad U.S.½ salad2 pizzas Chile¼ salad4 pizzas

14. Recall increasing opportunity cost Opportunity cost increases as production increases within each country Each country uses its best pizza maker to make its first pizzas Then, the next best pizza maker is used, etc. The same applies to salads

15. Production possibilities curve Recall from last lecture that all of the points along PGQ are the efficient points of the production possibilities curve Recall that this shape occurs due to increasing opportunity costs as more is produced

16. Production possibilities curve Without trade, only points along arc PGQ (or points between this arc and the origin) can be consumed We will see that gains can be made by trade

17. The world market In the world market, there is an equilibrium price (based on world supply and world demand) Any one country that enters or exits the market usually does not change the market price much For ease of discussion, assume that entry or exit by any one country does not change the world price

18. Consumption possibilities curve If we produce at point G, we can trade goods at the given market price Production at G (with trade)  Consumption anywhere along FGH

19. Which consumption possibility curve is best? We could produce at one of the red dots before we start trading However, note that there are fewer consumption sets possible than producing at G

20. Optimal production in an open economy Since the red line is suboptimal, we will not utilize it Similarly, any point except G will produce a similar result to the red line Suboptimal consumption possibilities for any production except G

21. Optimal production in an open economy Solution Produce such that the “line of trade possibilities” is tangent to the production possibilities curve In this case, point G is tangent to line FGH

22. Supply and demand analysis of trade As we just analyzed, we saw that total surplus goes up when world trade is possible However, we will see that there are winners and losers to trade Note that the winners’ gain is larger than the losers’ loss

23. Market for cars, w/o trade Suppose that without trade, 40,000 cars are sold at a price of $14,000

24. Market for cars, w/o trade Consumer surplus is blue shaded area Producer surplus is red shaded area

25. Market for cars, with trade Notice that the world price for cars is $10,000 At this price, notice that 20,000 cars will be supplied and 60,000 cars will be demanded in this market

26. Market for cars, with trade What will happen? This is unlike the case of rent control, since the shortage is picked up by the world market 20,000 domestic cars will be purchased 40,000 foreign cars will be purchased Imports

27. Surplus with trade Consumer surplus increases substantially Producer surplus decreases, but does not change as much as consumer surplus does Imports

28. Without imports (left) With imports (right) Imports

29. Net gain Imports

30. A similar exercise can be done for a country that is a net exporter When a country is a net exporter, the world price is above what it would be if trade was not possible (See Figure 9.7 for an example) Consumer surplus decreases when trade occurs Producer surplus increases when trade occurs Overall, total surplus increases

31. Tariffs and quotas Even when trade is not prohibited, countries sometimes control the amount of a particular good imported Tariff Tax that must be paid for each unit of the good imported Quota A binding limit set on the amount of a good that can be imported

32. What happens when we impose a tariff? In this case, the tariff imposed is $1000 per ton of sugar imported We will see that some potential economic surplus is lost when the tariff is imposed

33. What happens when we impose a tariff? Total surplus without tariffs Shaded area

34. What happens when we impose a tariff? With a tariff, the price paid by consumers is the world price plus the amount of the tariff Think of a tariff just like a tax This increases the quantity supplied domestically and decreases the amount imported

35. What happens when we impose a tariff? Quantity supplied domestically increases Imports decrease Before, 100 tons minus 20 tons, or 80 tons After, 80 tons minus 40 tons, or 40 tons

36. Total surplus and tariff money collected Consumer surplus (CS) Producer surplus (PS) Tariff revenue generated What is missing?

37. Total surplus and tariff money collected CS PS Tariffs What is missing? Two triangles are lost with the imposition of tariffs

38. Total surplus and tariff money collected The two triangles lost are potential surplus that could be gained Notice that relative to open global trade, producer surplus is higher See Economic Naturalist 9.2 to see an example of why there is pressure to impose tariffs Consumer surplus is lower with the tariff (relative to open global trade)

39. Quotas Quotas are similar to tariffs, except: Domestic supply plus quota determines supply available in a country’s market Equilibrium in this example is price of 125, 80,000 TV’s

40. What else is different with quotas? With quotas, no revenues are directly generated Those with right to import and export gain economic rents Example: See Economic Naturalist 9.3 for groups that benefited with “voluntary export restraints,” which is a form of quota

41. “Outsourcing” “Outsourcing” has been a controversial term in the media in recent years There are definitely short-run costs of outsourcing Displaced workers Buildings and machinery that gets unused

42. “Outsourcing” Long-run benefits of outsourcing Each country can specialize what it has comparative advantage in Technological improvements lower the costs of trade Lower costs to consumers

43. How to make sure your job does not get outsourced Make sure it requires a lot of face-to- face contact Construction work Repair labor Health care Make sure that you have skills that nobody else has

44. Final thoughts about “outsourcing” Trade policy can be formed such that those that are displaced are not any worse off Some of the gains from “making the pie bigger” can be transferred to those that get displaced Justification for re-training programs for displaced workers Overall, the standard of living of a country improves with trade Example: Think how much bananas would cost if we could not import them

45. Summary Trade improves overall surplus Some people win, while others lose Trade barriers, such as protectionism, quotas, and tariffs limit the gains from trade Outsourcing has short-run costs but long-run benefits in a country’s economy
