Protecting Competition in the American Economy: Merger Control, Tech Titans, Labor Markets

Author

  • Carl Shapiro

Abstract

Accumulating evidence points to the need for more vigorous antitrust enforcement in the United States in three areas. First, stricter merger control is warranted in an economy where large, highly efficient and profitable "superstar" firms account for an increasing share of economic activity. Evidence from merger retrospectives further supports the conclusion that stricter merger control is needed. Second, greater vigilance is needed to prevent dominant firms, including the tech titans, from engaging in exclusionary conduct. The systematic shrinking of the scope of the Sherman Act by the Supreme Court over the past 40 years may make this difficult. Third, greater antitrust scrutiny should be given to the monopsony power of employers in labor markets.
