Antitrust law regulates the competition between business firms in unregulated markets (and in varying degrees in regulated markets, where it supplies a benchmark standard). Thus, all privately owned economic entities are subject to or affected by the antitrust laws (federal or state), ranging from the largest multinationals to self-employed individuals, e.g., lawyers. Antitrust law constrains business behavior that injures the competitive process, encompassing such topics as price fixing, boycotts, monopolization, mergers, price discrimination, distributorship limitations and similar trade restrictions. Antitrust analysis is increasingly economic in its orientation and therefore economic analysis will form a vital part of the course. Supplementary economic readings are suggested for students without previous economic background (and for others who may wish to refresh their knowledge).
