question
Costs increase as a firm shortens the development horizon because
answer
A. more tasks must be undertaken concurrently; this lessens the amount of learning that can be incorporated
question

question
The average product of labor is defined as the
answer
output divided by the labor input usage
question
The marginal product of labor is defined by the
answer
change in output divided by the change in labor input usage.
question
The marginal product of labor can be illustrated geometrically as the
answer
slope of the total product curve with respect to labor.
question
Average variable cost is equal to the
answer
total variable cost divided by the level of output.
question
Whenever average variable cost is declining with increases in output,
answer
marginal cost at first decreases and then increases with output
question
Whenever marginal product is declining with increasing use of an input,
answer
total product is increasing at a decreasing rate as input use increases
question
When average product is at a maximum, marginal product is
answer
equal to average product.
question
Whenever average product is declining with increases in input usage,
answer
marginal product is less than average product
question
Diminishing marginal returns
answer
are consistent with increasing returns to scale
question
Break-even analysis usually assumes
answer
average variable costs are constant.
question
The opportunity cost of a firm's inputs
answer
is the value of the inputs in their most highly valued alternative use.
question
If average variable cost is increasing with increases in output, total fixed cost will
answer
remain unchanged with increases in output.
question
The addition to total cost resulting from the addition of the last unit of output is known as
answer
marginal cost.
question
Short-run marginal cost eventually increases with increasing output because
answer
eventually marginal returns will diminish.
question
When average variable cost is at its minimum,
answer
marginal cost is less than average total cost.
question
The long-run average cost curve slopes upward if there are
answer
diseconomies of scale

answer
sunk cost
question
When setting rates that natural monopolists can charge, regulatory commissions attempt to establish a maximum price
answer
where price equals average variable cost plus a fair return on invested capital of monopolist.
question

answer
It will never allow its price to be in the inelastic portion of the industry demand curve.
question

answer
oligopolistic.
question
In the model of monopoly, firms produce a
answer
differentiated product with considerable control over price.
question
A decreasing-cost industry is one in which
answer
input prices fall or technology improves as firms enter the industry.
question
Oligopoly is a market structure that necessarily has
answer
a small number of firms but more than one.

Oligopoly is the only market structure in which one finds
answer
firm interdependence.
