Krista operates a dry-cleaning business in Tampa that incurs $900 per month in fixed costs. Last month her total output equaled 3,000 pounds of clothes.

These numbers suggest that the firm producing this output has: a. economies of scale b. diseconomies of scale c. constant return to scale d. diminishing returns
c
The short-run is a period that is: a. less than a week b. less than a month c. long enough to vary output but not plant capacity d. long enough to make all economic adjustments

d
The change in total output resulting from a one-unit increase in the quantity of an input used, holding the quantities of all other inputs constant is: a. average cost b. average product c. marginal cost d. marginal product
d
The slope of a long-run average total cost curve exhibiting increasing returns to scale is: a. zero b. infinite c. positive d. negative
d
The swoosh-shape of the marginal cost curve is caused by the ___ having a powerful influence lower levels and the _____ having a powerful influence at high levels of output. a. diminishing returns effect; specialization effect b. diminishing returns effect; spreading effect c. spreading effect; fixed cost effect d. specialization effect; diminishing returns effect
d
The term diminishing returns refers to a: a. falling interest rate that can be expected as one's investment in a single asset increases b. reduction in profits caused by increasing output beyond the optimal point c. decrease in total output due to overcrowding, when too much labor is used with too little land or capital d. decrease in the extra output due to the use of an additional unit of a variable input, when more and more of the variable input is used and all other things are help constant
d
Buford Bus Manufacturing installs a new assembly line. As a result, the output per worker increases. The marginal cost of output at Buford: will increase (the MC curve will shift up). will decrease (the MC curve will shift down). will be unchanged. is at its maximum.
decrease
A firm that has diminishing returns in the management's ability to use and disseminate information as it increases production in the long run best demonstrates: being too small for the relevant market. diseconomies of scale. not having enough managers. economies of scale.
diseconomies of scale.
When Aishe's Bar-B-Que produces 10 pork sandwiches, the total cost is $5. When 11 pork sandwiches are produced, the total cost rises to $6. From this we know that the marginal cost of the eleventh pork sandwich: can't be calculated without more information. is greater than the average cost of 11 pork sandwiches .is less than the average cost of 11 pork sandwiches. is equal to the average cost of 11 pork sandwiches.
is greater than the average cost of 11 pork sandwiches
The marginal cost curve intersects the average variable cost curve at: its maximum. no point; the curves don't intersect. its end point. its lowest point.
lowest point
As production increases and the fixed cost is divided by larger quantities of output, average fixed cost drops. This is referred to as the _____ effect. spreading increasing returns constant cost diminishing returns
spreading
In the short run, as output gets larger: fixed cost gets smaller. average total cost decreases after the point of diminishing returns. marginal cost gets smaller. the average variable cost curve gets closer to the average total cost curve.
the average variable cost curve gets closer to the average total cost curve.
