Differences in the interpretation and the enforcement of antitrust laws are in part rooted on the issue of focus. One such issue pertains to the question of whether the policy focus should be on

A) domestic firms versus multinationals.
B) intrastate trade versus interstate trade.
C) monopoly output versus monopoly pricing
D) monopoly behavior versus monopoly structure.

The debate on whether antitrust laws should concentrate on the behavior of monopolies (how they act in the market) or their structure (the setup of the market that allows monopolies to exist) is a significant point of contention in the interpretation and enforcement of these laws. This focus impacts how regulations are applied and what aspects of a company's operations are scrutinized.
