As companies become increasingly big through mergers and acquisitions -- especially in technology, health care, and several other industries -- how should rules and regulations change with the times?

Esteemed Stanford professor and Chief Economist at the DOJ's Antitrust Division, Susan Athey, joins Bethany and Luigi to discuss these changes. Why did the DOJ and FTC make them?
