Define opportunity cost. What is your opportunity cost of attending a class at 11:00 A.M.? How does it differ from your opportunity cost of attending a class at 8:00 A.M.?
In spite of the lower opportunity cost of rail-gun projectiles instead of missiles, does the U.S. Navy continue to face an increasing additional cost, in terms of forgone ship production, to obtain additional weapons? Explain briefly.
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 5 million more smartphones and moving to production combination C?
You and a friend decide to spend \(100 each on concert tickets. Each of you alternatively could have spent the \)100 to purchase a textbook, a meal at a highly-rated local restaurant, or several Internet movie downloads. As you are on the way to the concert, your friend tells you that if she had not bought the concert ticket, she would have opted for a restaurant meal, and you reply that you otherwise would have downloaded movies. Identify the relevant opportunity costs for you and your friend for the concert tickets that you purchased. Explain briefly.
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?
| Economics | Biology |
| 100 | 40 |
| 90 | 60 |
| 80 | 75 |
| 70 | 85 |
| 60 | 93 |
| 50 | 98 |
| 40 | 100 |
