Glossary of competition terms

This Glossary is based on definitions from DG COMP’s Glossary of terms used in EU competition policy (© European Union, 2002) and the OECD’s Glossary of industrial organisation economics and competition law (© OECD, 1993). Each term is enriched with references of national case laws from the e-Competitions Bulletin and Concurrences Review.

Collective dominance

The Judgment of the Court of First Instance of 10 March 1992 "Italian Flat Glass’" was the first case in which court procedures confirmed that a collective dominant position can take place in oligopolist markets when ”two or more undertakings jointly have, through agreements or licences, a technological lead affording them the power to behave to an appreciable extent independently of their competitors, their customers and ultimately of their consumers”.
