Absolute and Comparative Advantage Review 5

comparative advantage exists when a particular tas one or a good can be produced at a lower opportuni y one nation than by a potential trading partner. Whe ountries specialize in the goods for which they have omparative advantage, the allocation of resources (la bor and capital) between nations is more efficient, a r a greater level of overall production and income th possible without trade. arefully explain how the story of the production o anet Money t-shirt demonstrates the principle of 6 omparative advantage

Per Unit Opportunity Cost Review Per Unit Opportunity Cost = Opportunity Cost Units Gained Assume it costs you $50 to produce 5 t-shirts. What is your PER UNIT cost for each shirt? $10 per shirt Now, take money our of the equation. Instead of producing 5 shirts you could have made 10 hats. 1. What is your PER UNIT OPPORTUNITY COST for each shirt in terms of hats given up? 1 shirt costs 2 hats 2. What is your PER UNIT OPPORTUNITY COST for each hat in terms of shirts given up? 1 hat costs a half of a shirt 8

Per Unit Opportunity Cost Review Ronald Mc. Donald can produce 20 pizzas or 200 burgers Papa John can produce 100 pizzas or 200 burgers 1. What is Ronald’s opportunity cost for one pizza in terms of burgers given up? 1 pizza cost 10 burgers 2. What is Ronald’s opportunity cost for one burger in terms of pizza given up? 1 burger costs 1/10 pizza 3. What is Papa John’s opportunity cost for one pizza in terms of burgers given up? 1 pizza costs 2 burgers 4. What is Papa John’s opportunity cost for one burger in terms of pizza given up? 1 burger costs 1/2 pizza Ronald has a COMPARATIVE ADVANTGE in the production of burgers Papa John has a COMPARATIVE ADVANTAGE in the 9 production of pizza

Absolute and Comparative Advantage Absolute Advantage • The producer that can produce the most output OR requires the least amount of inputs (resources) • Ex: Papa John has an absolute advantage in pizzas because he can produce 100 and Ronald can only make 20. Comparative Advantage • The producer with the lowest opportunity cost. • Ex: Ronald has a comparative advantage in burgers because he has a lowest PER UNIT opportunity cost. Countries should trade if they have a relatively lower opportunity cost. They should specialize in the good that is “cheaper” for them to produce. 10

Practice FRQ

A. Which country has an absolute advantage in the production of tractors? Explain how you determined your answer. B. Which country has an absolute advantage in the production of cars? Explain how you determined your answer. C. Which country has a comparative advantage in the production of cars? Use the concept of opportunity cost to explain how you determined your answer. D. For Xanadu, what is the opportunity cost of producing one car? E. If the two countries specialize and trade with each other, which country will import cars? Explain why?

10 Points Possible (2 Points For EACH: 1 point answer, 1 point explanation) A. Answer-Xanadu Explanation- Because they can produce more total tractors than Atlantis. B. Answer-Atlantis Explanation- Because they can produce more total cars than Xanadu.

(2 Points For EACH: 1 point answer, 1 point explanation) C. Answer- Atlantis Explanation- Because the opportunity cost for Atlantis to make one car is 1/3 a tractor which is less than the opportunity cost for Xanadu (1 car =2 tractors). D. Answer- Opportunity Costs is 2 Tractors. No explanation required

(2 Points For EACH: 1 point answer, 1 point explanation) E. Answer- Xanadu will import cars Explanation- Xanadu should not make cars. They should specialize in making tractors and import cars from Atlantis since they have a lower opportunity cost.

Pineapples Kenya Radios 30(1 P costs 1/3 R) 10 (1 R costs 3 P) India 40 (1 P costs 1 R) 40 (1 R costs 1 P) Kenya wants Radios If the terms of trade for 1 radio is greater than 3 pineapples then Kenya is worse off and should make radios on their own. India wants Pineapples If the terms of trade for 1 radio is less than 1 pineapple then India is worse off and should make pineapples on their own. What terms of trade benefit both countries?

Pineapples Kenya Radios 30(1 P costs 1/3 R) 10 (1 R costs 3 P) India 40 (1 P costs 1 R) 40 (1 R costs 1 P) Trading 1 radio for 2 pineapples will benefit both If Kenya produces radios by themselves, they give up 3 Pineapples for each radio. If they can trade 2 pineapples for each radio they are better off. If India produces pineapples by themselves, they give up 1 pineapple for one radio. If they can get 2 pineapples for one radio they are better off. The countries trade at a lower opportunity cost than if they made the products themselves!

Comparative Advantage Practice Create a chart for each of the following problems. • First- Identify if it is a output or input question • Second-Identify who has the ABSOLUTE ADVANTAGE • Third-Identify who has a COMPARATIVE ADVANTAGE • Fourth- Identify how they should specialize 1. Sara gives 2 haircuts or 1 perm and hour. Megan gives 3 haircuts or 2 perms per hour. 2. Justin fixes 16 flats or 8 brakes per day. Tim fixes 14 flats or 8 brakes per day. 3. Hannah takes 30 minutes to wash dishes and 1 hour to vacuum the house. Kevin takes 15 minutes to wash dishes and 45 minutes to vacuum. 4. Americans produce 50 computers or 50 TVs per hour.
