4) Table 17-28
Suppose that two firms determine that each could lower its costs and increase its profits
if both reduced their advertising budgets. But in order 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 product, 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 A
Breaks agreement Maintains agreement
and advertises and does not advertise
Refer to Table 17-28. Which of the following statement(s) correctly characterizes the
outcome of this game?
a.Both Firm A and Firm B have a dominant strategy to advertise.
b.There is a Nash equilibrium when both firms advertise.
c.Although both firms collectively would earn higher profits by maintaining the
agreement not to advertise, self- interest will cause each firm to break the agreement.
d.All of the above are correct.

13) Table 17-1
Imagine a small town in which only two residents, Rochelle and Alec, own wells that
produce safe drinking water. Each week Rochelle and Alec work together to decide how
many gallons of water to pump. They bring the water to town and sell it at whatever
price the market will bear. To keep things simple, suppose that Rochelle and Alec can
pump as much water as they want without cost so that the marginal cost of water equals
zero. The weekly town demand schedule and total revenue schedule for water is shown
in the table below:
Refer to Table 17-1. Suppose the town enacts new antitrust laws that prohibit Rochelle
and Alec from operating as a monopoly. How many gallons of water will be produced
and sold once Rochelle and Alec reach a Nash equilibrium?
a.600
b.700
c.800
d.900
