CHAPTER 3 – QUESTION FOR REVIEW (61)
No 2. Give an example in which one person has an absolute advantage in doing something but another person has a comparative advantage.
= example of absolute advantage: in this case, time is the only input. So we can determine absolute advantage by looking at how much each type of production takes. The rancher has an absolute advantage both in producing meat and in producing potatoes because she requires less time than the farmer to produce a unit of either good. The rancher needs to input only 20 minutes to produce an ounce of meat, whereas the farmer needs 60 minutes. Similiarly, the rancher need only 10 minutes to produce an ounce of potatoes, whereas the farmer needs 15 minutes. Based on this information, we conclude that the rancher has the lower cost of producing potatoes, if we measure cost by the quantity of inputs.
=example of comparative advantage: the farmer has a lower opportunity cost of producing potatoes than the rancher. An ounce of potatoes cost the farmer only 14 ounce of meat, but it cost the rancher 12 ounce of meat. Conversely, the rancher has a lower opportunity cost of producing meat than the farmer: an ounce of meat costs the rancher 2 ounce of potatoes, but it cost the farmer 4 ounce of potatoes. Thus the farmer has a comparative advantage in growing potatoes, and the rancher has a comparative advantage in producing meat. No 4. Explain how absolute advantage and comparative advantage differ!
=the people who can produce good with the smaller quantity of inputs is said to have an absolute advantages in producing good. The person who has the smaller opportunity cost of producing the good is said to have a comparative advantage.
