  2. Class 18 • March 29 • 7 • Important date: • Midterm exam (chapters 1 – 3), Tuesday, April 3 • 9:20am – 10:50am

  3. Result of Quiz 5 N = 35 Range = 6.5 – 10 Average = 8.72 1. Absolute advantage vs. comparative advantage 2. Two statements 3. Productivity data of two nations and two products (a) Absolute advantage (b) Comparative advantage (c) Should they trade? (d) How to draw a PPF? 4. Production cost data of two nations and two products (a) Absolute advantage (b) Comparative advantage (c ) Should they trade?

  4. Result of Problem set 2 N = 36 Range = 41 – 99.5 Average = 86.6

  5. 4. Trade policies of importing countries 4.1. Major types of import barriers 4.2. Reasons for import barriers 4.3. Effects of specific import policies 4.4. Related issues

  6. 3.7. Exchange rate and its determination 3.7.1. Exchange rate: the ratio at which two currencies are traded (the price of one currency in terms of another) e.g., 1 US dollar = 1.56 Canadian dollars 1 US dollar = 7.90 Chinese yuans 3.7.2. Importance of exchange rate in trade 3.7.3. History of money (currency)

  7. 4.1. Major types of import barriers (a) Import tax (tariff) -- Fixed amount per unit (e.g., $0.5 per unit) -- A percentage of the price (e.g., 5%) -- A combination of the two (b) Import quota -- Quota on total import -- A quota on a country basis (c) Tariff rate-quota: a combination of tariff & quota e.g., First 200 mmt, 2% tariff 201 -- 500 mmt, 4% Above 500 mmt, 6%

  8. 4.1. Major types of import barriers (d) Other import restrictions -- State trading (e.g., China’s grain import) -- Technical restrictions (e.g., high quality standards) 4.2. Major reasons for import barriers (a) Redistribution of welfare (b) National security (c) Protest new industries (d) Protect producers and farmers (e) Other reasons (e.g.,health, public safety, etc.)

  9. 4.3. Effects of specific import policies (a) Small vs. large importer (b) A graphic analysis -- A small importer -- A large importer (c) A mathematical analysis -- A small importer Qd = 20 - 1 P Qs = -1 + 2 P ED = Qd - Qs = 21 - 3P ES faced by the importer: Pw = 5 Price after trade = Quantity of import = Change in CS = Change in PS = Gains from trade =

  10. 4.3. Effects of specific import policies (c) A mathematical analysis -- A large importer Qd = 20 - 1 P Qs = -1 + 2 P ED = 21 - 3P ES faced by the importer: ES = -1.5 + 2 P Price after trade = Quantity of import = Change in CS = Change in PS = Gains from trade = change in (CS+PS) =

  11. 4.3. Effects of specific import policies (d) Impacts of an import tax: a small importer Qd = 20 - 1 P Qs = -1 + 2 P ES faced by the importer: Pw = 5 --------------------------------------------------------------------------------------------------- Import P* Qs Qd CS PS Tax CS+PS+Tax --------------------------------------------------------------------------------------------------- No trade 0 7 13 13 84.5 42.25 0 126.75 Free trade w/ no transp. cost 6 5 9 15 112.25 20.25 0 132.50 An import tax of $1 per unit 3 6 11 14 98 30.25 3 131.25 ---------------------------------------------------------------------------------------------------

  12. 3. International trade theory 3.1. Simple examples: two-person cases 3.2. Absolute and comparative advantages 3.3. Trade between two countries 3.4. The sources of comparative advantage 3.5. Other explanations for international trade 3.6. Measurement of the gains from trade 3.7. Exchange rate and its determination
