cost of producing every level of output in the long run.

one?
A) All possible economies of scale have been exhausted.

cost curve's minimum point.

must be true of the plant's average cost of production curve?
A) It is upward-sloping.
B) It is downward-sloping.

Economies of scope refers to the decrease in average total cost that can occur when a firm

B) has monopoly power in world markets.
C) controls the raw materials used as inputs.

product.

,Producing 200 units of good Y and 100 units of good X in the same factory costs the firm

another factory costs the firm $75,000. So if the firm produces the two goods together, it
achieves:
A) quadratic returns to scale.
B) diseconomies of scope.
C) economies of scope.
D) diseconomies of scale and diseconomies of scope. correct answers C) economies of scope.

C) will decrease if the firm hires more labor.
D) All of the above are correct. correct answers D) All of the above are correct.

Answer whether the following statements are true or false:
A) Over time, more experienced workers will demand higher wages and therefore, will lead
to an increased in the cost of production for the producers.
B) When you produce more, the average cost of production increases. correct answers A)
False & B) False

A reason why a perfectly competitive firm's demand for labor curve slopes downward is that
A) each additional unit of labor hired is less efficient than previously hired units.
B) in the short run, as more labor is hired, labor's marginal product falls because of the law of
diminishing returns.
C) the extra cost of hiring additional units of labor increases as a firm hires more units of
labor.
D) the firm's demand curve for the product that uses labor is downward sloping. correct
answers B) in the short run, as more labor is hired, labor's marginal product falls because of
the law of diminishing returns.

The term "derived demand" refers to
A) the demand for financial products called derivatives.
B) the demand for a factor of production that is derived from the demand for the good the
factor produces.
C) a firm's estimated demand curve derived from sales data.
D) a demand curve that derives from the availability of resources. correct answers B) the
demand for a factor of production that is derived from the demand for the good the factor
produces.

12) The price of a factor of production that is in fixed supply is called
A) economic rent.
B) economic profit.
C) a compensating differential.
D) opportunity cost. correct answers A) economic rent.

b. the firm can afford more sophisticated technology in production.

design.
c. Toyota was experiencing an excess demand for its automobiles which it had difficulty
keeping up with.
d. Toyota was focused on "churning" out cars for which it did not invest sufficiently in

What is the difference between "diminishing marginal returns" and "diseconomies of scale"?
a. Diminishing marginal returns, which applies only in the short run when at least one factor
is fixed, explains why marginal cost increases, while diseconomies of scale, which applies in
the long run when all factors are variable, explains why average cost increases.
b. Diminishing marginal returns, which applies only in the long run when all factors are
variable, explains why average variable cost increases, while diseconomies of scale, which
applies in the short run when at least one factor is fixed, explains why average total cost
increases.
c. Both concepts explain why average total cost increases after some point but diminishing
marginal returns applies only in the short run when there is at least one fixed factor, while
diseconomies of scale apply in the long run when all factors are variable.
