2) There are four homes along Belmont Circle, which surrounds a small plot of land.
The land currently has no trees, and the 4 homeowners -- Adams, Benitez, Chen, and
Davis -- are considering the idea of contributing to a pool of money that will be used to
plant up to 4 trees. The table represents their willingness to pay, that is, the maximum
amount that each homeowner is willing to contribute toward each tree.
Suppose the cost to plant each tree is $90. How many trees should be planted to
maximize the total surplus of the four homeowners?
a.1
b.2
c.3
d.4
3) Table 17-29
Suppose that two firms, Wild Willy's Wonderdrink (Firm W) and Hyper Hank's
Hydration (Firm H), comprise the market for energy drinks. Each firm determines that
it could lower its costs and increase its profits if both firms reduced their advertising
budgets. But for the plan to work, each firm must agree to refrain from advertising.
Each firm believes that advertising works by increasing the demand for the firm's
energy drinks, but each firm also believes that if neither firm advertises, the cost
savings will outweigh the lost sales. The table below lists each firm's individual profits:
Firm W
Breaks agreement Maintains agreement
and advertises and does not advertise
Refer to Table 17-29. Which of the following statements does not correctly
characterize the outcome of this game?
a.There is a Nash equilibrium.
b.Only one firm has a dominant strategy.
c.The game is an example of the Prisoners' Dilemma.
d.Both firms collectively would earn the highest joint profits by maintaining the
agreement not to advertise.
4) A competitive firm has been selling its output for $10 per unit and has been
maximizing its profit. Then, the price rises to $14, and the firm makes whatever
adjustments are necessary to maximize its profit at the now-higher price.Once the firm
has adjusted, its
a.marginal revenue is lower than it was previously.
b.marginal cost is lower than it was previously.
c.quantity of output is higher than it was previously.
d.All of the above are correct.
5) Which of the following movements
would illustrate the effect in the market for bullet-proof vests of an increase in the price
of Kevlar?

b.Point C to Point B
c.Point C to Point D
d.Point A to Point D
6) The dictionary defines equilibrium as a situation in which forces
a.are in balance.
b.are the same.
c.clash.
d.remain constant.
7) Competitive firms decide how much output to sell by producing output until the
price of the good equals
a.marginal product.
b.the value of marginal product.
c.marginal cost.
d.marginal profit.
8) If firms in a monopolistically competitive market are earning economic profits,
which of the following scenarios would best describe the change existing firms would
face as the market adjusts to the long-run equilibrium?
a.an increase in demand for each firm
b.a decrease in demand for each firm
c.a downward shift in the marginal cost curve for each firm
d.an upward shift in the marginal cost curve for each firm

b.The marginal tax rate decreased from 2009 to 2010.
c.The marginal tax rate remained constant from 2009 to 2010.

12) The demand schedule below pertains to sandwiches demanded per week.
Suppose Harry, Darby, and Jake are the only demanders of sandwiches. Also suppose
the following:
€¢ x = 2.
€¢The current price of a sandwich is $3.00.
