Answer:
b. False.
Step-by-step explanation:
Southwest does not possess all the characteristics of a monopolist in the market. Some of the characteristics of a monopolist are: profit maximizer, price maker, high barriers to entry, single seller, and price discrimination. Since Delta Airlines is able to enter the market, it means that Southwest is a competitor with Delta and not a monopolist in the real sense. The fact is that Southwest has a dominant strategy in this market.
