Question 11. How are the slope of a production possibilities frontier and the opportunity cost of the goods related?
a. the slope is a graphical picture of the cost of increasing output of both goods at once
b. the slope is a graphical measure of the growth rate of the economy
c. the slope is a graphical representation of the cost of reducing unemployment
d. the slope is a graphical picture of the rate of trade-off between the goods
Question 12. In terms of the production possibilities diagram, the principle of _increasing_ (opportunity) cost simply asserts that the frontier is
a. downward sloping
b. bowed outward from the origin
c. upward sloping

Question 13. Suppose a society produces only guns and butter. When it uses all its resources for the production of guns and operates efficiently, it can produce 240 guns per year. We also know that its ppf is _bowed out from the origin_. In order to produce 20 tons of butter, this society must reduce gun production to 200 guns per year. Suppose this society were to increase butter production by another 20 tons, to 40 tons per year. Then, operating efficiently, it would produce
a. exactly 160 guns per year
b. less than 160 guns per year
c. more than 160 guns per years
d. still 200 guns per year if it is operating efficiently.
Question 14. In terms of efficiency, any point on an economy's production possibilities frontier is as good as any other. T F
Question 15. Assuming that productive resources are specialized, the opportunity cost of an item increases as production of it rises. Therefore, we expect that firms will produce more if
a. the price increases
b. the price decreases
c. the opportunity cost is greater than the price
d. the income of buyers increases.
Question 16. Only market economies have to answer the questions of what goods to produce, how to produce them, and for whom to produce them. T F
Question 17. Why does quantity demanded decrease when price increases?
a. people choose to reduce consumption of the item
b. people "drop out" of the market for the item
c. people find and buy substitutes for the item
d. all of the above
Question 18. An upward-sloping supply curve for a product shows that
a. buyers are willing to pay more for a scarce product
b. suppliers are willing to increase production of the product if they can receive higher prices for it
c. buyers are not affected by sellers' production costs
d. the supply of a product is not influenced by the price buyers are willing to pay
Question 19. The Red Jacket Mountain View Inn in New Hampshire charges $99 for a room in the winter ski season and $94 during the summer months. The number of rooms and operating costs are constant year round. These price differences indicate
a. rightward shifts in the demand curve in the summer
b. rightward shift in demand in the winter
c. leftward shifts in the supply curve in the summer
d. a leftward shift in demand in the winter
Question 20. In early 1996, Congress proposed a law that would greatly reduce price supports for many farm products. If the bill were to pass, what would most likely happen to the number of families in farming?
a. it would fall, because farm product prices would be lower
b. it would rise because farm product prices would rise
c. it would rise, because farm product prices would fall
d. it would fall. because farm product prices would rise
