The WSJ reports this afternoon that the U.S. Department of Justice’s Antitrust Division has opened an investigation into potential anticompetitive activities in the chocolate industry. The disclosure follows issuance of search warrants in Canada for a similar probe. See This Price-Fixing Case Looks Pretty Sweet.
The article says that "Justice Department antitrust enforcers are inquiring about the pricing practices of chocolate makers, who have been grappling with higher dairy costs." It also names Hershey, Mars, Nestle, and Cadbury as actual or likely subjects of the U.S. investigation.
