A.   120 workers and 19 machines.
B.   70 workers and 9 machines.
C.   75 workers and 9 machines.
D.   50 workers and 10 machines.
Question #2
In order to achieve economic efficiency, managers of a firm should:
A.   Use the highest quality inputs.
B.   Hire the most highly skilled employees.
C.   Produce the most output with the least amount of inputs.
D.   Use the least costly input combination.
E.   Use the most sophisticated technology.
Question #3
Which of the following statements is true?
A.   Many different production processes can be technically efficient, but only the method that involves the lowest possible cost is economically efficient.
B.   There are many production processes that are both technically and economically efficient, but only one of these involves the lowest possible cost.
C.   Many different production processes can be economically efficient, but only the method that involves the lowest possible cost is technically efficient.
D.   There is only one production process that is technically efficient, and this process is also economically efficient.
Question #4
LCD screens replaced plasma screens because a LCD manufacturing facility can produce various sized screens for various products (smartphones, TVs, tablets, etc.). This is an example of a technology:
A.   Increasing diseconomies of scale.
B.   None of the available answers.
C.   Providing constant returns to scale.
D.   Reducing indivisible setup costs.
E.   Providing inconstant returns to scale.
Question #5
Economies of scale are associated with:
A.   Declining per-unit costs.
B.   Increased monitoring costs.
C.   Increasing per-unit costs.
D.   Increased levels of bureaucracy within a firm.
Question #6
A firm finds that producing 30,000 books costs $180,000 and producing 40,000 books costs $200,000. This pattern might be explained by:
A.   Economies of scale.
B.   Diseconomies of scale.
C.   Economies of scope.
D.   Diminishing marginal productivity.
Question #7
Which of the following is most likely an example of diseconomies of scale?
A.   Alpha-Beta Inc. raised its price by 10 percent after a 5 percent increase in production costs.
B.   The Dynasty Co. increased production capacity by 25 percent and experienced a 50 percent increase in its total cost.
C.   The per-unit costs on Excel Publishing Company's manuals fell after it received a large order from the government.
D.   Widget Manufacturing doubled its production by opening a new plant that was identical to its old plant.
Question #8
Suppose that per-unit costs for Alpha-Zeta Co. are $25 when they are producing 50,000 units. Now suppose that the firm increases production to 50,100 units and total costs are $2,000,000 at that level of production. Question: What is occurring as the firm increases production from 50,000 to 50,100 units?
A.   Diseconomies of scale due to the fact that per-unit costs increased from $25 to $39.92.
B.   Economies of scale due to the fact that per-unit costs decreased from $25 to $23.56.
C.   Economies of scale due to the fact that per-unit costs decreased from $25 to $22.
D.   Diseconomies of scale due to the fact that per-unit costs increased from $25 to $41.92.
Question #9
Suppose a firm has economies of scale over all levels of its output and production levels, its long-run average total cost curve will:
A.   Slope downward.
B.   Slope upward.
C.   Be horizontal.
D.   Be vertical.
E.   Be extremely upwardly sloping and steep.
Question #10
Suppose a firm has diseconomies of scale over all levels of its output, its long-run average total cost curve will:
A.   Be horizontal.
B.   Be relatively flat.
C.   Slope downward.
D.   Be vertical.
E.   Be upward sloping.
Question #11
The long-run average cost curve’s shape is primarily determined by:
A.   The macroeconomic conditions.
B.   Indivisible set up costs.
C.   Economies of scope.
D.   Economies and diseconomies of scale.
E.   Technological change.
Question #12
The long-run average cost of producing 19 units of output is $56, and the long-run average cost of producing 20 units is also $56. These numbers illustrate:
A.   Constant returns to scale.
B.   Economies of scale.
C.   Decreasing marginal productivity.
D.   Diseconomies of scale.
Question #13
Proctor and Gamble’s expansion from soap production to shampoo production is an example of:
A.   Constant returns to scale.
B.   Diseconomies of scale.
C.   Economies of scale.
D.   None of the available answers.
E.   Economies of scope.
Question #14
An example of economies of scope is:
A.   Increasing per unit costs given increased unit production.
B.   Decreasing per unit costs given increased unit production.
C.   Google utilizing its information processing capabilities to provide data analysis services to other firms.
D.   The 200,000 unit production threshold for GM to make a profit on a car model.
E.   None of the available answers.
