Duopoly

Duopoly in the European Union Law

Concept of Duopoly provided by the “Glossary of terms used in EU competition policy” (Antitrust and control of concentrations, published in 2002): Special case of oligopoly: industry structure with two sellers. In competition cases the term is often also used for situations where two main sellers dominate the competitive structure and a fringe of smaller sellers adapts to their behaviour. The two main sellers are then referred to as the duopoly.
