Part I: Foundations of Antitrust Law
Historical Origins and Purpose
1. Question: The primary purpose of antitrust law in the United States is to:
A) Protect competitors from competition
B) Protect competition and consumer welfare
C) Maximize corporate profits
D) Regulate all business activities
Answer: B
Rationale: The primary purpose of antitrust law is to protect competition
and consumer welfare, not competitors. The antitrust laws are designed to
promote a competitive marketplace that benefits consumers through lower
prices, higher quality, and greater innovation. As the Supreme Court has
stated, the antitrust laws are "the Magna Carta of free enterprise" and are
as important to the preservation of economic freedom as the Bill of Rights
is to the protection of fundamental personal freedoms.
2. Question: The Sherman Antitrust Act was enacted in:
A) 1890
B) 1914
C) 1936
D) 1950
, Answer: A
Rationale: The Sherman Antitrust Act was enacted in 1890. It was the first
federal statute to prohibit monopolies and restraints of trade. The Act was
named after Senator John Sherman of Ohio, who was the principal author.
Section 1 prohibits contracts, combinations, and conspiracies in restraint of
trade, and Section 2 prohibits monopolization, attempts to monopolize, and
conspiracies to monopolize.
3. Question: The Clayton Act was enacted in:
A) 1890
B) 1914
C) 1936
D) 1950
Answer: B
Rationale: The Clayton Act was enacted in 1914 as a supplement to the
Sherman Act. It addresses specific practices that were not clearly covered
by the Sherman Act, including price discrimination, tying arrangements,
exclusive dealing, and mergers that may substantially lessen competition.
The Clayton Act also provides for private treble damages and injunctive
relief.
4. Question: The Federal Trade Commission Act was enacted in:
A) 1890
B) 1914
C) 1936
D) 1950
