ambiguous.

ambiguous.

in the production of the new oak tables increased?

cost of going to graduate school to get a Ph.D. in economics decreases for many

professors will

6) Figure 14-9
In the figure below, panel (a) depicts the linear marginal cost of a firm in a competitive
market, and panel (b) depicts the linear market supply curve for a market with a fixed
number of identical firms.

the market when price is $2.00?
a. 10,000
b. 20,000
c. 40,000
d. 80,000
7) When a firm operates with excess capacity,
a.additional production would lower the average total cost.
b.additional production would increase the average total cost.
c.it must be a perfectly competitive firm.
d.it must be a monopolistically competitive firm.
8) If a monopolist's marginal costs increase by $1 for all levels of output, then the
monopoly price will
a.rise by $1.
b.rise by more than $1.
c.rise by less than $1.
d.not change, but profits will decrease.
9) Which of the following statements is correct?
a.The benefits that accrue to a monopoly's owners are equal to the costs that are
incurred by consumers of that firm's product.
b.The deadweight loss that arises in monopoly stems from the fact that the
profit-maximizing monopoly firm produces a quantity of output that exceeds the
socially-efficient quantity.
c.The deadweight loss caused by monopoly is similar to the deadweight loss caused by
a tax on a product.
d.The primary social problem caused by monopoly is monopoly profit.
10) Sellers respond to a surplus by cutting their prices.
a.True
b.False
11) Assume that a 4 percent decrease in income results in a 6 percent increase in the
quantity demanded of a good. The income elasticity of demand for the good is
a.negative, and the good is an inferior good.
b.negative, and the good is a normal good.
c.positive, and the good is an inferior good.
d.positive, and the good is a normal good.
12) If a tax shifts the demand curve upward (or to the right), we can infer that the tax
was levied on
a.buyers of the good.
b.sellers of the good.
c.both buyers and sellers of the good.
d.We cannot infer anything because the shift described is not consistent with a tax.

21) To produce honey, beekeepers place hives of bees in the fields of farmers. As bees
gather nectar, they pollinate the crops in the fields, which increases the yields of these
fields at no additional cost to the farmer. What might be a reasonable private solution to
this externality, and how might the solution be reached?
