Both the EU and the US have well-developed competition policies that aim to prevent and penalise anticompetitive behaviour.
Merger control in the EU, carried out solely by the European Commission, is more centralised than in the US. In order to ensure fair competition in the internal market, EU competition policy has strict rules on state aid, whereas US legislation has no provisions in this area.
EC and US competition authorities cooperate on cases which affect both jurisdictions. The question of state aid may be raised in the on-going EU-US negotiations for a Transatlantic Trade and Investment Partnership.
While the European Parliament (EP) is only consulted on matters of competition policy, the US Congress plays a more active role. High-profile merger cases in the US are subject to close scrutiny from Congress, including Congressional hearings.
