20
Q

21
Q

Which of the following is an explicit cost

A

the wages paid to workers

22
Q

Which of the following is NOT an explicit cost

23
Q

The opportunity costs associated with the use of resources owned by a firm are

A

implicit costs

24
Q

Which of the following would be considered an implicit cost

A

foregone rent on assets owned by the firm

25
The sum of the explicit and implicit costs incurred in the production process is called
total cost
26
Economic profit is
total revenues minus total costs
27
When total revenue minus total cost is equal to zero, the firm is
earning a normal profit
28
Which of the following is an example of a fixed input - the acreage of a farmer's land - machinery - the size of a firm's plant
all of these
29
Which of the following represents the key difference between the short run and the long run
in the short run, the firm makes commitments to a certain type of production technology, which are represented as fixed costs in the short run. For example, they have signed a lease on a particular production facility. These fixed costs do not exist in the long run.
30
The short run is a time period such that
the existing firms in the market do not have sufficient time to increase the size of their existing plant or build a new factory
31
The long run is a period of
sufficient length to allow a firm to alter its plant size and capacity and all other factors of production
32
The increase in total output that results form a unit increase in one unit of a variable input is equal to the input's
marginal product
33
The law of diminishing marginal returns implies that, in the short run
the marginal product of the variable input must eventually decrease
34
The ___ is the situation in which the marginal product of labour is greater than zero and declining as more labour is hired.
law of diminishing returns
35
Fixed costs are BEST defined as
cost that do not vary with output
36
Which of the following is MOST likely to be a fixed cost for a business
property taxes on the firm's building
37
Marginal cost is BEST defined as
the amounted added to total cost when one more unit of output is produced
38
Economies of scale are created by greater efficiency of capital and by
increased specialization of labor
39
If a firm's long-run average cost curve is rising, it is experiencing
diseconomies of scale
40
Diseconomies of scale exist for all of the following reasons EXCEPT
firm size is too small
