In contrast, in monopolistic competition, several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts (折扣) are often used as part of a marketing strategy to influence sales.
Oligopoly occurs when a few companies dominate the sales of a product or service. For example, only five airline carriers control more than 70 percent of all ticket sales in the United States. In oligopoly, serious competition is not considered desirable because it would result in reduced revenue for every company in the group. Although price wars do occur, in which all companies offer substantial savings to customers, a somewhat similar tendency to raise prices simultaneously is also usual.
Finally, monopoly occurs when only one firm sells the product. Some monopolies have been tolerated for producers of goods and services that have been considered basic or essential, including electricity and water. In these cases, it is government control, rather than competition, that protects and influences sales.
Which of the following would be the best title for the passage?
A.Monopolies.
B.The Commodity Market.
C.The Competition Continuum.
