In their newest policy publication in Concurrences, Annika Stöhr and Oliver Budzinski from TU Ilmenau's Economic Theory Group comment on the debate about revised guidelines for Art. 102 TFEU (prohibition of the abuse of market dominance) in the face of the challenges brought by digital ecosystems and abuse of market power by digital giants. The authors take the perspective of dynamic competition economics and derive four recommendations for the future enforcement of abuse control and related merger control: (i) they advocate to abandon the as-efficient-competitor standard embraced in the late 2000s, (ii) they emphasize the relevance on focusing on exploitative abuses as well as on exclusionary ones, (iii) they suggest to implement a concept of systemic market power as a guideline to enforcement, and (iv) they argue that the same enhanced market power standard should also be applied in the corresponding policy of merger control.
