Summary

51

A trust is a cartel that places the assets of competing companies in the custody of a board of trustees. During the last decades of the 19th century, trusts engaged in anticompetitive strategies to eliminate competition and raise prices, such as predatory pricing.

52

The Sherman Act of 1890 and the Clayton Act of 1914 are the two most important antitrust laws. The Sherman Act marked the first attempt of the U.S. government to outlaw monopolizing behavior. Because this act was vague, the Clayton Act was passed to define anticompetitive behavior more precisely.

53

The Clayton Act prohibited (1) price discrimination, (2) exclusive dealing, (3) tying contracts, (4) stock acquisition, and (5) interlocking directorates.

54

The Robinson-Patman Act of 1936 strengthened the Clayton Act by prohibiting certain forms of price discrimination. This law is called the “Chain Store Act” because it was aimed at large retail chain stores that were obtaining volume discounts.

55

The Celler-Kefauver Act of 1950 strengthened the Clayton Act declaring illegal the acquisition of the assets of one firm by another firm if the effect is to lessen competition.

56

The rule of reason and the per se rule are the two main philosophies the courts have used in interpreting antirust law. Under the rule of reason, monopolist were not subject to prosecution unless they acted in an anticompetitive manner.

57

The Supreme Court decision in the Alcoa case of 1945 replaced the rule of reason with the per se rule, which states that the mere existence of monopoly is illegal. Today, the trend is in favor of dominant firms because of international competition.

58

A horizontal merger is a merger of two competing firms. A vertical merger is a merger of two firms where one produces an input used by the other firm. A conglomerate merger is a merger of two firms producing unrelated products.

59

Deregulation is a movement that began in the1980’s to eliminate regulations primarily in the transportation and telecommunications industries. Today, the current trend is toward further deregulation resulting from federal budget cuts.

60

Marginal cost pricing is a competitive pricing strategy for a regulated natural monopoly. Using this approach, regulators set the monopolist’s price equal to its marginal cost. Another method is for regulators to establish a fair-return price equal to long-run average cost and the monopolist earns zero economic profit.

61

Regulation of a natural monopoly is justified on the basis of market failure. Two other cases based on market failure include externalities and imperfect information.
