49. Summary
49

50. 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.
50

51. 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.
51

52. The Clayton Act prohibited (1)
price discrimination, (2) exclusive
dealing, (3) tying contracts, (4)
stock acquisition, and (5)
interlocking directorates.
52

53. 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.
53

54. 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.
54

55. 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.
55

56. 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.
56

57. 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.
57

58. 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.
58

59. 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.
59

60. 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.
