Economists generally agree that U.S. antitrust policy is complex, changing over time, divided among several U.S. federal government agencies, and subject to frequent court reversals. The underlying question remains whether the U.S. needs more or less regulation of market structures.
Key questions are:
- Are U.S. markets becoming less competitive because of mergers and acquisitions?
- Are U.S. markets becoming more competitive because of new technology?
- Are U.S. markets becoming more or less competitive because of globalization?
- Is enough information available for wise antitrust enforcement?
