KUIS 2 Pengantar Ekonomi1
Asdos: Venty
1. Ernie's Earmuffs produces 200 earmuffs per
year at a total cost of $2,000 and $400 of this cost is fixed. What is Ernie's
total variable cost?
A)
$2,400 B)
$2,000 C) $1,600 D)
$800
2. Are the short-run average total cost
curve and the long-run average cost both U-shaped for the same reasons? If so,
carefully explain these reasons. If not, explain why each curve is U-shaped.
Answer: The curves are U-shaped for quite different
reasons. In the short run, the firm's plant, that is, its _ _ _ , is _ _ _. Therefore the only way to
increase output is by increasing the quantity of the variable factor, _ _ _. Initially as _ _ _ increases, there are gains from
specialization and division of labor, which leads the _ _ _ to rise and the average total cost to fall as
more workers are employed. Eventually, however, the firm runs up against its
capital constraint and workers must share tools and building space. As this
happens, decreasing marginal returns begin and average total cost eventually
begins to rise.
In
the long run, both _ _ _
and _ _ _
are _ _ _.
As a firm expands its use of both factors, gains from specialization of both
labor and capital cause average total costs to fall. Eventually, however, the
business becomes so large it is difficult to coordinate and control. When this
happens, average total cost begins to rise.
3. What are economies of scale? What is the
main source of economies of scale? Explain the difference between increasing
marginal returns and economies of scale.
4. If the minimum efficient scale of a
firm is small relative to the demand for the good, then
A)
many small firms can compete in the market.
B)
several large firms will enter the market thereby reducing competition.
C)
there will be no economic profits for any small firms, so no new firms will
ever enter the market.
D)
the firms already in the market have lower average total cost than any new firm
entering the market.
5. In perfect competition, restrictions on
entry into an market
A)
apply to both capital and labor. B) apply to
labor but not to capital.
C)
apply to capital but not to labor. D) do not exist.
