Short Answer

94. How does the study of economics depend upon the phenomenon of scarcity?

95. One tradeoff society faces is between efficiency and equity. Define each term. If the U.S. government redistributes income from the rich to the poor, explain how this action affects equity as well as efficiency in the economy.

96. Define opportunity cost. What is the opportunity cost to you of attending college? What was your opportunity cost of coming to class today?

97. With the understanding that people respond to incentives, outline the possible outcome for teachers if the K-12 school year is extended to 11 months per year instead of the existing 9 months per year.

98. Using this outline, draw a circular-flow diagram representing the interactions between households and firms in a simple economy. Explain briefly the various parts of the diagram.

99. The prairie dog has always been considered a problem for American cattle ranchers. They dig holes that cattle and horses can step in and they eat grass necessary for cattle. Recently, ranchers have discovered that there is a demand for prairie dogs as pets. In some areas prairie dogs can sell for as high as $150. Cattlemen are now fencing off prairie dog towns on their land so these towns will not be disturbed by their cattle. Draw a production possibilities frontier showing a rancher's production option between cattle production and prairie dog production showing increasing opportunity cost and show what would happen in each of the following situations. (Use a separate graph for each situation.) a. The outcome is efficient, with ranchers choosing to produce equal numbers of cattle and

prairie dogs. b. As a protest against the government introducing the gray wolf back into the wild in their

state, ranchers decide to withhold 25 percent of the available grassland for grazing. c. The price of prairie dogs increases to $200 each, so ranchers decide to allot additional

land for prairie dogs. d. The government grants new leases to ranchers, giving them 10,000 new acres of

grassland each for grazing. e. A drought destroys most of the available grass for grazing of cattle, but not for prairie

dogs since they also eat plant roots.

100. Identify each of the following topics as being part of microeconomics or macroeconomics: a. the impact of a change in consumer income on the purchase of luxury automobiles b. the effect of a change in the price of Coke on the purchase of Pepsi c. the impact of a war in the Middle East on the rate of inflation in the United States d. factors influencing the rate of economic growth e. factors influencing the demand for tractors f. the impact of tax policy on national saving g. the effect of pollution taxes on the U.S. copper industry h. the degree of competition in the cable television industry i. the effect of a balanced-budget amendment on economic stability j. the impact of deregulation on the savings and loan industry

101. Explain the difference between absolute advantage and comparative advantage. Which is more important in determining trade patterns, absolute advantage or comparative advantage? Why?

102. The only two countries in the world, Alpha and Omega, face the following production possibilities frontiers.

a. Assume that each country decides to use half of its resources in the production of each

good. Show these points on the graphs for each country as point A. b. If these countries choose not to trade, what would be the total world production of

popcorn and peanuts? c. Now suppose that each country decides to specialize in the good in which each has a

comparative advantage. By specializing, what is the total world production of each product now?

d. If each country decides to trade 100 units of popcorn for 100 units of peanuts, show on the graphs the gain each country would receive from trade. Label these points B.

103. Julia can fix a meal in 1 hour, and her opportunity cost of one hour is $50. Jacque can fix the same kind of meal in 2 hours, and his opportunity cost of one hour is $20. Will both Julia and Jacque be better off if she pays him $45 per meal to fix her meals? Explain.

104. Gary and Diane must prepare a presentation for their marketing class. As part of their presentation, they must do a series of calculations and prepare 50 PowerPoint slides. It would take Gary 10 hours to do the required calculation and 10 hours to prepare the slides. It would take Diane 12 hours to do the calculations and 20 hours to prepare the slides. a. How much time would it take the two to complete the project if they divide the calculations

equally and the slides equally? b. How much time would it take the two to complete the project if they use comparative

advantage and specialize in calculating or preparing slides? c. If Diane and Gary have the same opportunity cost of $5 per hour, is there a better solution than

for each to specialize in calculating or preparing slides?

SHORT ANSWER

94. ANS:

Since economics is the study of how society allocates its scarce resources, if there were no scarcity, there would be no need for economics. Everyone could have all the goods and services they wanted. No one would have to make decisions based on tradeoffs, because there would be no opportunity cost associated with the decision. (It is difficult to conceive of a situation where time is not scarce, however).

95. ANS: Efficiency is the property of society getting the most it can from its scarce resources. Equity is defined as the property of distributing economic prosperity fairly among the members of society. Often, these two goals conflict. When the government redistributes income from the rich to the poor, it reduces the reward for working hard. Fewer goods and services are produced and the economic pie gets smaller. When the government tries to cut the economic pie into more equal slices, the pie gets smaller. Policies aimed at achieving a more equal distribution of economic well-being, such as the welfare system, try to help those members of society who are most in need. The individual income tax asks the financially successful to contribute more than others to support the government.

96. ANS: Whatever must be given up to obtain some item it its opportunity cost. Basically, this would be a person's second choice. The opportunity cost of a person attending college is the value of the best alternative use of that person's time. For most students this would be the income the student gives up by not working. A student's opportunity cost of coming to class was the value of the best opportunity the student gave up. (For most students, that seems to be sleep.)

DIF: 2 REF: 1-1 TOP: Opportunity cost MSC: Interpretive

97. ANS: The concept of working longer per year would be perceived by many teachers as a definite increase in the cost of teaching. Even with additional compensation, many teachers look at summers off as a major benefit of the education profession. If this benefit were eliminated or diminished, some teachers may perceive that the marginal cost of teaching would now be greater than the marginal benefit and would choose to leave teaching.

101. ANS: Absolute advantage refers to productivity, as in the producer who can produce a product at a lower cost in terms of the resources used in production. Comparative advantage refers to the producer who can produce a product at a lower opportunity cost. Comparative advantage is the principle upon which trade patterns are based. Comparative advantage is based on opportunity cost, and opportunity cost measures the real cost to an individual or country of producing a particular product. Opportunity cost is therefore the information necessary for an individual or nation to determine whether to produce a good or buy it from someone else.

102. ANS:

a. Alpha would be producing 125 units of peanuts and 75 units of popcorn (point A on its

production possibilities frontier) and Omega would be producing 50 units of peanuts and 150 units of popcorn (point A on its production possibilities frontier).

b. The total world production of peanuts would be 175 units and the total world production of popcorn would be 225 units.

c. The total world production of peanuts would now be 250 units and the total world production of popcorn would now be 300 units.

d. Alpha would be producing 250 units of peanuts and would trade 100 of them to Omega, leaving Alpha with 150 units of peanuts. Alpha would then receive 100 units of popcorn from Omega. Omega would be producing 300 units of popcorn and would trade 100 of them to Alpha, leaving Omega with 200 units of popcorn. Omega would then receive 100 units of peanuts from Alpha.

104. ANS: a. If both tasks are divided equally, it will take 11 hours for the calculations and 15 hours for the

writing, for a total of 26 hours. b. If Diane specializes in calculating and Gary specializes in preparing slides, it will take 22 hours

to complete the project. c. If Diane specializes in calculating, her opportunity cost will be $60; hence, Diane would be

better off if she paid Gary any amount less than $60 to do the calculating. Since Gary's opportunity cost of doing the calculations is only $50, he would be better off if Diane paid him between $50 and $60 dollars to do the calculations. In this case, the total time spent on the project would be 20 hours.
