Oligopolies are characterized by many firms
Economic cost is always less than accounting cost
In the short run
some factors of production are variable, while at least one factor of production is fixed
When the long - run average total cost curve is horizontal, a firm has economies of scale.
When a firm is experiencing diminishing returns
none of the above
The minimum efficient scale is
the output level beyond which the firm will not experience scale economies.
Fixed costs do not vary as output changes.
A perfectly competitive firm that is maximizing profit produces the quantity of output at which price equals marginal cost.
If marginal cost is increasing, average variable cost must also be increasing.
A firm experiences diminishing marginal returns because:
at least one factor of production is fixed.
If a firm suffers an economic loss, its:
price is less than its average total cost.
How does the firm -specific demand curve in a perfectly competitive market compare to that in a monopoly?
The firm - specific demand curve in a perfectly competitive market is horizontal. The demand curve in a monopoly is downward sloping.
Which of the following is true if a firm has indivisible inputs?
The long - run average cost curve is downward sloping at lower levels of output.
If marginal revenue is $10 and marginal costs is $8, the firm should increase its output.
Economic cost differs from accounting cost because accountants do not consider implicit costs.
In short - run equililbrium for a competitite firm economiv profits:
may be positibe, negative, or zero
Monopolistically competitive industries are characterized by no barriers to entry.
If the marginal cost of producing the next unit of output exceeds the average total cost, then:
the average total cost curve is increasing
Diminishing marginal returns occur only in the long run
When the firm increases output and the costs rise proportionately, then the long - run average cost curve is _________ and the firm is experiencing ____________
horizontal; constant returns to scale
