The Confederation of Swedish Enterprise welcomes the European Commission’s review of the guidelines for horizontal and vertical merger control. It is essential that the regulatory framework remains up to date and reflects the realities faced by businesses. There is a need to clarify and, to some extent, adjust how the Commission assesses efficiency aspects of mergers, as well as various qualitative parameters that influence competition between firms. These should be evaluated within the framework of a robust economic analysis based on consumer welfare, while also to some extent considering effects beyond the relevant market.
