Quizplus · Accepted Answer

Antitrust enforcement in the United States focuses on the degree of market concentration within a market. This means that the government is concerned about whether a particular industry or market is dominated by a small number of firms or if there is healthy competition among a larger number of firms. The idea is to prevent monopolies or oligopolies from forming and potentially harming consumers through lack of competition. This focus on market concentration is reflected in the government's use of metrics like the Herfindahl-Hirschman Index to gauge the level of competition within a market.
