  1. Question

    The accompanying table shows three possible combinations of fixed cost and average variable cost. For each choice, average variable cost is constant (it does not vary with the quantity of output produced).

    Choice Fixed cost Average variable cost
    1 $8,000 $1.00
    2 12,000 0.75
    3 24,000 0.25
    1. For each of the three choices, calculate the average total cost of producing 12,000, 22,000, and 30,000 units. For each of these quantities, which choice results in the lowest average total cost?

    2. Suppose that the firm, which has historically produced 12,000 units, experiences a sharp, permanent increase in demand that leads it to produce 22,000 units. Explain how its average total cost will change in the short run and in the long run.

    3. Explain what the firm should do instead if it believes the change in demand is temporary.

  2. Question

    In each of the following cases, explain whether the firm is likely to experience economies of scale or diseconomies of scale and why.

    1. an interior design firm in which design projects are based on the expertise of the firm’s owner

    2. a diamond-mining company
