Explain monopolization, attempts and conspiracies to monopolize and why they are
illegal.
Monopolies
Monopoly power is the ability to effectively prevent others from competing in
the same market. A company’s market share is determined by evaluating
the relevant product and geographic markets. A relevant product market
refers to products that are similar with respect to price, quality, and
adaptability. The relevant geographic market concerns the area where the
company sells its products. To address the problem of monopolization,
Section 2 of the Sherman Act prohibits monopolies and all attempts or
conspiracies to monopolize. Thus, Section 2 prohibits both agreements
among businesses and, unlike Section 1, unilateral conduct by one &rm.
Monopolization — Following the establishment of monopoly power it must
also be shown that the company either attained the monopoly power unfairly
or abused that power, once attained. Monopoly power is the ability to
control prices or to exclude competitors from the marketplace. In grappling
Attempts to Monopolize — Section 2 also prohibits attempts to
monopolize, but the courts have had difficulty de&ning what distinguishes
undesirable conduct likely to lead to a monopoly from healthy, competitive
conduct. The standard test applied by the courts requires proof of a speci&c
intent to monopolize plus a dangerous probability of success, but does not
de&ne “intent” or “success.”
Conspiracies to Monopolize — Section 2 also condemns conspiracies to
monopolize. Few cases involve this offense alone, as any conspiracy to
monopolize would also constitute a combination in restraint of trade in
violation of Section 1.
