5) Table 17-26
Two prescription drug manufacturers (Firm A and Firm B) are faced with lawsuits from
states to recover the healthcare related expenses associated with side-effects from its
drugs. Each drug manufacturer has evidence that indicates that taking its prescription
drug causes liver failure. State prosecutors do not have access to the same data used by
drug manufacturers and thus will have difficulty recovering full costs without the help
of at least one of the drug manufacturer's studies. Each firm has been presented with an
opportunity to lower its liability in the suit if it cooperates with attorneys representing
the states.
Refer to Table 17-26. If both firms follow a dominant strategy, Firm B's profits (losses)
will be a. $-12m
b. $-24m
c. $-40m
d. $-100m

To maximize total surplus, a benevolent social planner would choose which of the
following outcomes?

10) 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 $600 and the families have agreed to split
the cost of installing the streetlights equally. To maximize their own surplus, how many
streetlights would the Brown's like the town to install?
a.0 streetlights
b.1 streetlight
c.2 streetlights
d.3 streetlights
