Trends in Competition Law

In the past decade, competition law enforcement has gained prominence across the European Union, United States, United Kingdom, and other regions. With more than 125 competition agencies operating globally, enforcement has significantly influenced the way markets and businesses behave.

“Competition law enforcement has taken center stage in the last decade, driven by high-profile actions worldwide.”

Complexities and Convergence

Despite ongoing debates about the proper scope of competition law and the differing priorities of national enforcement agencies, a notable convergence in approaches has emerged. Yet, inconsistencies remain, shaped by economic contexts, legal environments, and competing theories of harm.

“Some inconsistencies in analysis are unavoidable due to differing economic and legal contexts as well as various theories of harm.”

Author’s summary: Political use of competition enforcement is increasing, posing challenges to fairness, consistency, and market credibility in global regulation.
