Exam 13: The Costs of Production

The graph of the production function plots total cost versus quantity of output.

Economists include both explicit and implicit costs while accountants include only implicit costs. ​

The opportunity cost of capital is an implicit cost almost every business incurs.

Average variable cost is equal to total variable cost divided by quantity of output.

Diminishing marginal productivity implies decreasing total product.

-Refer to Table 13-12. Which firm has constant returns to scale over the entire range of output?

For a large firm that produces and sells automobiles, which of the following costs would be a variable cost?

Figure 13-6 The following figure depicts average total cost functions for a firm that produces automobiles. ​ ​ ​ -Refer to Figure 13-6. At levels of output less than P, the firm experiences

Economists and accountants usually disagree on the inclusion of implicit costs into the cost analysis of a firm.

Which of the following explains why long-run average total cost at first decreases as output increases?

Figure 13-6 The following figure depicts average total cost functions for a firm that produces automobiles. ​ ​ ​ -Refer to Figure 13-6. Which of the curves is most likely to characterize the short-run average total cost curve of the smallest factory?

If the average-total-cost of producing five units is $10, and the marginal-cost of producing the fifth unit is $10, then the average-total-cost curve is at its minimum at five units.​

Let L represent the number of workers hired by a firm, and let Q represent that firm's quantity of output. Assume two points on the firm's production function are (L = 12, Q = 122) and (L = 13, Q = 130). Then the marginal product of the 13th worker is

A second or third worker may have a higher marginal product than the first worker in certain circumstances.

Table 13-11 ​ ​ ​ -Refer to Table 13-11. Which firm is experiencing diseconomies of scale?

When a factory is operating in the short run,

Table 13-13 Listed in the table are the long-run total costs for three different firms. uantity Firm A 100 100 100 100 100 Firm B 100 200 300 400 500 Firm C 100 300 600 1,000 1,500 -Refer to Table 13-13. Firm A is experiencing economies of scale.

Suppose that for a particular firm the only variable input into the production process is labor and that output equals zero when no workers are hired. In addition, suppose that when four units of output are produced, the total cost is $175, and the average variable cost is $33.75. What would the average fixed cost be if ten units were produced?
