Simon Vande Walle Market sharing : An overview of EU and national case law


Are market sharing cartels still “an endemic feature of European business activity” ? Which sectors are particularly prone to bid rigging ? What are the enforcement trends in relation to market sharing cartels ? The panorama that emerges from the cases in this Special Issue sheds some light on these questions. The period covered runs from 2017 to June 2023. During that period, competition authorities across Europe have uncovered a remarkable number of market sharing cartels, including bid rigging schemes. The cases lay bare several noteworthy trends and tendencies. This foreword reflects on some of these trends and the number of cases.
