question
Average fixed costs rise continuously as quantity of output rises.
answer
F
question
Average total cost and average variable cost are minimized at the same level of output.
answer
F
question
Average total cost of producing 100 units of output is $5. If the marginal cost of producing the 101st unit is $6, then average total cost of 101 units is less than $5.
answer
F
question
Demand for the product of an industry in perfect competition is assumed to be inelastic.
answer
F
question
Firms maximize their profits by producing the output level where MR = MC.
answer
T
question
The upward-sloping portion of the perfectly competitive firm's average total cost curve is the firm's short-run supply curve.
answer
T
question
For a firm in a perfectly competitive industry, price equals marginal revenue.
answer
T
question
Individual firms in perfectly competitive industries decide what price to charge for their output and what quantity of output to produce.
answer
F
question
A firm that is earning a positive profit in the short run and expects to continue doing so has an incentive to expand its scale of operation in the long run.
answer
F
question
A firm's long-run average cost curve represents the minimum cost of producing each level of output when the scale of production can be adjusted. I
answer
T
question
The increase in total cost that results from producing one more unit of output is the marginal cost.
answer
T
question
When marginal cost is between average variable cost and average total cost, marginal cost is increasing.
answer
T
question
The marginal cost curve intersects the average total cost curve at ATC's minimum point.
answer
T
question
The marginal revenue curve for a perfectly competitive firm will be downward sloping.
answer
F
question
For a perfectly competitive firm, when P = MC = ATC, the most profit the firm can earn is zero.
answer
T
question
Perfectly competitive firms maximize their profit by producing the output level where P = MR = AVC.
answer
F
question
A firm in a perfectly competitive industry can raise its price above the market price to increase revenue.
answer
F
question
The long run industry supply curve is made up of the zero-profit equilibrium levels of output as the industry expands due to entry of new firms.
answer
T
question
A perfectly competitive industry's supply curve is upward sloping
answer
T
question
In efficient markets, investment capital flows toward profit opportunities
answer
T
question
If marginal cost is increasing, then average variable cost must be increasing simultaneously.
answer
F
question
Average total cost of producing 100 units of output is $5. If the marginal cost of producing the 101st unit is $4, then average total cost of 101 units is less than $5.
answer
T
question
Perfectly competitive industries are characterized by a homogeneous product.
answer
T
question
Marginal costs reflect changes in variable costs
answer
T
question
If demand in a perfectly competitive market increases, then an individual firm in that industry will see its profits fall.
answer
F
question
In perfectly competitive industries, firms can easily enter and exit the industry in the long run.
answer
T
question
The shut-down decision is a short-run decision
answer
T
question
When price is sufficient to cover average variable costs, firms suffering short-run losses will continue to operate rather than shut down.
answer
T
question
When an increase of a firm's scale of production leads to higher average costs per unit produced, there is an increasing return to scale.
answer
F
question
In efficient markets, profit opportunities are quickly eliminated as they develop.
answer
T
question
Entry of new firms in an increasing-cost industry leads to an upward shift of the LRAC curve.
answer
T
question
In perfect competition, the short run individual firm's supply curve is made up of the zero-profit equilibrium levels of output as the industry expands due to entry.
answer
T
question
Economies of scale cannot be due only to the sheer size of a firm's operation.
answer
F
question
A firm that has increasing returns to scale in the long run does not experience diminishing marginal returns in the short run.
answer
F
question
If a firm earns short-run losses, it exits in the long run
answer
T
question
When a firm shuts down in the short run, it breaks even.
answer
F
question
A firm must earn an economic profit in order to receive a normal rate of return.
answer
F
question
Input prices fall as entry occurs in an increasing-cost industry
answer
F
question
Information on MC of production is all that is necessary to obtain the lon rung-industry supply curv for perfect competitione, because P = MC is the profit-maximization condition for all firms
answer
F
question
The horizontal sum of marginal cost curves (above AVC) of all the firms in a perfectly competitive industry is the short-run industry supply curve.
answer
T
question
A firm suffering short-run losses will continue to operate rather than shut down when price is less than its average variable costs.
answer
F
question
A firm that experiences only constant returns to scale will have a U-shaped long-run average cost curve.
answer
F
question
Firms in perfectly competitive industries that are earning short-run profits will likely break even in the long run.
answer
T
question
If, at the output where marginal revenue equals marginal cost, price is below average variable cost, a firm will shut down in the short run.
