Zusammenfassung: 
We discuss the design of an effective merger review policy for the 21st century. We argue that the practice of the past decades is inadequate and propose a move towards much stronger rebuttable structural presumptions. These presumptions establish that all mergers above certain thresholds are illegal unless the merging parties can prove that merger-specific efficiencies will be shared with consumers and yield tangible welfare gains. These presumptions are grounded on solid economics and also acknowledge the real-world limitations in enforcement resources and information asymmetries between companies and regulators. We outline how to establish such presumptions in practice, defending the implementation of an ex-ante system that selects in advance (rather than per transaction) which companies and markets are subject to the presumption. Finally, we outline which merger-related efficiencies can rebut the presumption.
