1 Econ 2: Principles of Economics Chapter 3 Questions for Review 1. Absolute advantage reflects a comparison of the productivity of one person, firm, or nation to that of another, while comparative advantage is based on the relative opportunity costs of the persons, firms, or nations. While a person, firm, or nation may have an absolute advantage in producing every good, they cannot have a comparative advantage in every good. 2. Many examples are possible. Suppose, for example, that Roger can prepare a meal of hot dogs and macaroni in just ten minutes, while it takes Anita 20 minutes. Also suppose that Roger can do all the laundry in three hours, while it takes Anita four hours. Roger has an absolute advantage in both cooking and doing the laundry, but Anita has a comparative advantage in doing the laundry. For Anita, the opportunity cost of doing the laundry is 12 meals; for Roger, it is 18 meals. 3. Comparative advantage is more important for trade than absolute advantage. In the example in problem 2, Anita and Roger will complete their chores more quickly if Anita does at least some of the laundry and Roger cooks the meals for both, because Anita has a comparative advantage in doing the laundry, while Roger has a comparative advantage in cooking. Problems and Applications 1. a. See Figure 2. If Maria spends all five hours studying economics, she can read 100 pages, so that is the vertical intercept of the production possibilities frontier. If she spends all five hours studying sociology, she can read 250 pages, so that is the horizontal intercept. The opportunity costs are constant, so the production possibilities frontier is a straight line.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
