This presentation provides an overview of the fundamental concepts of competition economics and their application in competition law enforcement. It introduces key economic principles used by competition authorities to assess market behaviour, identify anti-competitive practices, and evaluate whether business conduct or market structures are likely to harm competition and consumers.
The presentation covers core topics including market power, monopoly, market dominance, cartels, mergers and acquisitions, challenged conduct, theories of harm, relevant market definition, and market concentration. Together, these concepts provide the analytical framework that competition authorities use to investigate business practices, assess mergers, define markets, and promote competitive markets that enhance consumer welfare and economic efficiency.
