16) Table 17-5
The information in the table below shows the total demand for premium-channel digital
cable TV subscriptions in a small urban market. Assume that each digital cable TV
operator pays a fixed cost of $200,000 (per year) to provide premium digital channels in
the market area and that the marginal cost of providing the premium channel service to
a household is zero.
Refer to Table 17-5. Assume there are two profit-maximizing digital cable TV
companies operating in this market. Further assume that they are not able to collude on
the price and quantity of premium digital channel subscriptions to sell. How many
premium digital channel cable TV subscriptions will be sold altogether when this
market reaches a Nash equilibrium?
a. 6,000
b. 9,000
