these firms have suffered economic losses, and many sellers have left the industry.

10) Suppose a market is initially perfectly competitive with many firms selling an
identical product. Over time, however, suppose the merging of firms results in the

c.a decrease in market output and an increase in the price of the product.

14) Table 17-30
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 17-30. Discuss the difference between the monopoly outcome and the
Nash equilibrium.
15) The difference in wages that results from nonmonetary characteristics of different
jobs is called the

18) Comparing firms in perfectly competitive markets to monopoly firms, which
charges a price equal to marginal cost?
19) It costs a company $30,000 to produce 600 heart rate monitors. The company's cost
will be $30,070 if it produces an additional heart rate monitor. The company is currently
producing 600 heart rate monitors.
