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.

Business may be transacted through the use of intermediaries as well. (...)
