The Clayton Antitrust Act of 1914 was enacted to strengthen existing anti-trust laws and further limit business practices thought to be anticompetitive. Named after its principle author, Henry De Lamar Clayton Jr., the act would attempt to close some of the loopholes businesses found in the years following the Sherman Act of 1890 as well as curtail monopolistic activity.
The Sherman Antitrust Act of 1890, along with the Clayton Act of 1914 and the Federal Trade Commission Act of 1914, were groundbreaking statutes geared towards limiting monopolies and cartels. In the years following the Sherman Act, courts applied the law to trade unions, which found it impossible to organize so they could bargain with their employers. There were also a number of mergers, which reestablished the market power of the cartels outlawed by the Sherman Act.
Adding further strength to the Sherman Act, the Clayton Antitrust Act of 1914 would specifically outlaw the following conduct:
anti-competitive practice, confidentiality agreement, conflict of interest, dividing markets, price fixing, bid rigging, group boycott, disparagement, dumping, exclusive dealing, Sherman Antitrust Act of 1890, limit pricing, Federal Trade Commission Act of 1914, resale price maintenance
