4) Table 17-2
Imagine a small town in which only two residents, Abby and Brad, own wells that
produce safe drinking water. Each week Abby and Brad work together to decide how
many gallons of water to pump. They bring water to town and sell it at whatever price
the market will bear. To keep things simple, suppose that Abby and Brad can pump as
much water as they want without cost so that the marginal cost is zero. The weekly
town demand schedule and total revenue schedule for water is shown in the table
below:
Refer to Table 17-2. Suppose the town enacts new antitrust laws that prohibit Abby
and Brad from operating as a monopoly. What will be the price of water once Abby and
Brad reach a Nash equilibrium?
a.$12
b.$8
c.$6
d.$4
