Question

Quizplus · Accepted Answer

The fishing industry comes closest to the economist's definition of perfect competition, where there are many small firms, homogeneous goods, perfect information, ease of entry and exit, and no market power for any firm. In the airline industry, for example, there are relatively few large firms that dominate the market, which implies barriers to entry, non-homogeneous products, and market power. The soft drink industry is also characterized by a few dominant firms with strong brand recognition and marketing power. The cellular telephone service industry is also concentrated with a few large firms that can influence pricing and market outcomes.
