Competition policy encourages companies to offer consumers goods and services on the most favourable terms. It encourages efficiency and innovation and reduces prices. To be effective, competition requires companies to act independently of each other, and subject to the pressure exerted by their competitors.
Competition Policy Instruments

Antitrust
Articles 101 and 102 of the Treaty prohibit agreements which restrict competition and the abuse of dominance on a given market.

Cartels
A cartel is a group of independent companies which join together to fix prices, limit production or share markets or customers between them.

Mergers
Mergers can benefit the economy but some may reduce competition. Proposed mergers are examined to prevent harmful effects on competition.

State aid
A company receiving State aid has an advantage over competitors. State aid is generally prohibited unless compatible with EU rules.

Competition case search
Searches for published decisions can be carried out under policy area, case number, title and date.

Whistle-blower Communication Tools
Knowledge of cartels or other antitrust infringements can be shared anonymously with the Commission to help detect, stop and punish such infringements.
