Competition law (known as antitrust law in the U.S.) seeks to maintain the integrity of the marketplace by prohibiting anti-competitive practices and by subjecting corporate mergers and acquisitions to regulatory review if they have the potential to significantly reduce competition.
Historically, competition law developed and evolved almost exclusively within the jurisdictional boundaries of individual nation-states. More recently, the growing influence of multinational business enterprises has led to a corresponding increase in bilateral and regional cooperation among national competition authorities.
This guide focuses on researching competition law in jurisdictions outside the U.S., on comparing competition law and practice in two or more jurisdictions, and on efforts to coordinate and harmonize the enforcement of competition law across multiple jurisdictions.
