Mergers are a pivotal force in the economy, enabling companies to expand and thrive. They may reduce competition but they can also generate benefits - some in the shape of efficiencies - which can, in turn, lead to cost savings, improved products and enhanced services.
In June 2025, the OECD will hold a discussion to explore the different approaches and developments in considering efficiencies in merger control, including the types of efficiencies considered and the criteria to assess them. It will also discuss possible reasons why efficiencies as a defence or rebuttal in mergers remain rare, as is their acceptance by competition authorities and courts and raises some relevant questions for future discussions.
