This chapter considers abusive pricing practices under Article 102 TFEU and the Chapter II prohibition in the Competition Act 1998. It discusses cost concepts used in determining whether a price is abusive and deals with excessive pricing; conditional rebates; bundling; predatory pricing; margin squeeze; price discrimination; and practices harmful to the single market. Price discrimination may be both exploitative and exclusionary and an excessively high price may be a way of preventing parallel imports or excluding a competitor from the market; but the division may provide helpful insights into the way in which the law is applied in practice. In each section the application of Article 102 by the European Commission and the EU Courts is considered, followed by cases in the UK. Where appropriate, reference is made to the Commission’s Guidance on the Commission’s Enforcement Priorities in Applying Article [102 TFEU] to Abusive Exclusionary Conduct by Dominant Undertakings.
