Legal framework Predation/exclusion 4Abuse of dominance Discrimination?Dominance EU:>50% => presumption of dominance OFT: “unlikely to be dominant”

5. High prices Reluctance by lawyers to engage with “high” prices: – temporary high prices an inducement to correct shortages, etc? – choice of benchmark? – measuring cost may be difficult in practice especially with joint and common costs – price regulation is complex & requires specialised resources High prices? Legal framework Predation/exclusion 5Abuse of dominance Discrimination?Dominance

6. High prices => US and EU typically do not pursue high prices - but OFT guidelines suggest that excessive prices could be caught if “excessive” prices persist and entry is not induced. High prices? Legal framework Predation/exclusion 6Abuse of dominance Discrimination?Dominance
