Antitrust laws play an important role in ensuring that corporate transactions such as Mergers & Acquisitions have the benefit of competitive prices and quality of goods and services. The antitrust laws accomplish these goals by promoting and fostering competition in the marketplace and preventing anticompetitive mergers and business practices. In the last 20 years, virtually every developed nation in the West has created a sophisticated legal system to deal with restrictive agreements, abuse of market power and notification and regulation of mergers and acquisitions that pose a threat to competition.
Overview of US and EU laws:
The antitrust laws of the US and the EU address almost identical sets of anti-competitive practices and combinations, but they slightly differ with criteria of assessment and means of enforcement. While the US antitrust law aims for maximum diffusion of competition, the EU law aims at the diffusion of competitive power tempered by cooperation. The two laws offer different sets of remedies.
