9) Consider a small town with only three families, the Greene family, the Brown family,
and the Black family. The town does not currently have any streetlights so it is very
dark at night. The three families are considering putting in streetlights on Main Street
and are trying to determine how many lights to install. The table below shows each
family's willingness to pay for each streetlight.
Suppose the cost to install each streetlight is $900 and the families have agreed to split
the cost of installing the streetlights equally. If the residents choose to install the
number of streetlights that will maximize total surplus from the streetlights, how much
total surplus will the Greene family receive?
a.-$40
b.$0
c.$40
d.$60

a.neither excludable nor rival in consumption, a tornado siren is a common resource.
b.neither excludable nor rival in consumption, a tornado siren is a public good.

a.True
b.False

a.the economy cannot benefit from government intervention.

17) Scenario 19-1
Ferris B., a student at a community college, is considering what he should do for
summer employment. Two recruiters show up at his school in search of summer
workers. Recruiter A is looking for lifeguards to patrol the beach at an exclusive island
resort in the Caribbean. Recruiter B is looking for workers to staff positions at a
summer youth camp.
Refer to Scenario 19-1. Ferris is carefully considering the options that each recruiter
presents. On the basis of knowledge obtained in his economics class, Ferris concludes
that
a.the lifeguard job will be more fun than the summer camp job, so the wage for that job
will be higher than otherwise.
b.if the summer camp job doesn't require any special skills, the wage for that job will be
lower than otherwise.
c.since the summer camp job requires some night shift work, the wage for that job will
be lower than otherwise.
d.All of the above are correct.
18) Figure 8-6
The vertical distance between points A and B represents a tax in the market.
What happens to total surplus in this market when the tax is imposed?
a.Total surplus increases by $1,500.
b.Total surplus increases by $3,000.
c.Total surplus decreases by $1,500.
d.Total surplus decreases by $,3000.

a.too few good used cars being offered for sale.
b.wages that are too low relative to equilibrium levels.
c.too many good drivers buying too much automobile insurance.
d.people with average health buying too much health insurance.
20) Figure 8-26

21) Scenario 7-1
Suppose market demand is given by the equation
Refer to Scenario 7-1. If the market equilibrium price is $10, how much is total
consumer surplus in this market?
22) According to economists Hamermesh and Biddle, how much more do people who
are deemed more attractive than average earn?
23) The table below shows the quantities demanded of milk per month by four families
at various prices.
If the four families listed are the only demanders in this market and the price of a gallon
of milk increases from $4.00 to $5.00, what is the change in the market quantity
demanded?

marginal product of the last worker is 35 units of output. What is the firm's marginal
cost of producing its last unit of output?
25) Nike and Reebok (athletic shoe companies) are considering whether to advertise
during the Super Bowl. Devise a simple prisoners' dilemma game to demonstrate the
strategic considerations that are relevant to this decision. Does the repeated game
scenario differ from a single period game? Is it possible that a repeated game (without
collusive agreements) could lead to an outcome that is better than a single-period game?
Explain the circumstances in which this may be true.
26) Suppose consumers expect the price of a good to be higher in the future than it is
today. Would the current demand for the good increase or decrease?
27) Table 16-7

amount of its markup over marginal cost?
