Suppose that in Fig 2-2, the nation currently is producing combination D in the table and on the graph of the production possibilities curve. What is the opportunity cost of producing 20 million more tablet devices and moving to production combination F?
If the U.N. follows through on a proposal to add production targets for 148 more items to its Sustainable Development Goals, why might we expect that the opportunity cost in terms of other goods and services that must be forgone could be even greater? Explain briefly.
Suppose that in Fig 2-24, the nation with other wise the same background conditions as in Problem 2-23 currently has sufficient resources to produce combinations located along only the innermost production possibilities curve. If the nation produces no additional smartphones this year, will the intermediate-shifted PPC resulting from minimal economic growth or the farthest shifted PPC caused by more significant economic growth be more likely to apply next year?
The following table illustrates the points a student can earn on examinations in economics and biology if the student uses all available hours for study. Plot this student’s production possibilities curve. Does the PPC illustrate the law of increasing additional costs?
