3) Figure 19-2
Refer to Figure 19-2. This figure depicts labor demand and supply in a nonunionized

$12.50, then employment is a. 500
b.600
c.700
d.800

writing, he can earn $75. Lawrence is such a good writer that he can get paid for as
many hours of writing as he chooses to work.

subscriptions in a small urban market. Assume that each company that provides these
subscriptions incurs an annual fixed cost of $20,000 (per year) and that the marginal
cost of providing an additional subscription is always $16.
Refer to Table 17-7. Assume that there are two profit-maximizing internet radio
providers operating in this market. Further assume that they are not able to collude on
the price and quantity of subscriptions to sell. How much profit will each firm earn
when this market reaches a Nash equilibrium?
a. $12,000
b. $16,000
c. $52,000
d. $64,000

families pay 15% of the first $50,000 earned, 25% of the next $50,000 earned, and 35%
of any income over $100,000 to a tax system in which every family pays 20% of their
income less $20,000.
Refer to Scenario 20-1. What would the libertarians think of the proposed policy
change?
a.They would favor the current progressive policy over the proposed policy because it
accounts for diminishing marginal utility.
b.They would favor the proposed tax policy over the current progressive policy because
it would result in a negative tax for the poorest families.
c.They would favor the current progressive tax policy over the proposed policy because
it rewards those who work the hardest.
