How did the Clayton antitrust act attempt to close loopholes in earlier antitrust legislation?

The Clayton Antitrust Act of 1914 aimed to strengthen previous antitrust laws, particularly the Sherman Act, by addressing specific practices that were not adequately covered. It prohibited certain anti-competitive practices, such as price discrimination, exclusive dealing contracts, and mergers that could substantially lessen competition. Additionally, the Act clarified that labor unions and agricultural organizations were not considered illegal combinations, thus protecting their activities from antitrust scrutiny. Overall, it sought to provide a more comprehensive framework for regulating corporate behavior and promoting fair competition.
