Read this chapter to learn about how government policies have been in place to curve the power of imperfect competition. Also identify what the US has used regulations to protect consumers and limit the excesses of businesses via antitrust policies.
A joint venture between competing long-distance companies carries the danger that they may end up colluding. It is also possible that only some long-distance firms would be involved to the exclusion of other rival firms, as happened in the joint venture between General Motors and Toyota. On the other hand, the venture might be allowed in the U.S. under the notion that the firms might need to cooperate to face global competition. Another consideration is that technological change in this industry is occurring so rapidly that competitors can emerge from anywhere. Cable companies, internet providers, and cellular-phone companies all compete with regular telephone companies.
