Please join Steptoe partner Jonathan Sallet and Professor Jonathan Baker on Wednesday, February 28, for a discussion of antitrust enforcement activity in the US and what could be in store as we move into 2018.  Key issues to be discussed include enforcers’ new emphasis on vertical theories of harm when reviewing mergers; how two-sided markets should be assessed when defining product markets; and renewed questions about the nature and evidence of competitive harm that must be shown, particularly regarding prospective buyer power.
