The IMF did not name names in its latest World Economic Outlook, but said interest in the problem has mounted amid the rise of the tech industry. The report comes just weeks after the U.S. Democratic senator and presidential candidate Elizabeth Warren vowed to break up Amazon.com Inc, Facebook Inc and Alphabet Inc’s Google. She has proposed legislation that would require tech companies that offer online marketplaces to refrain from competing on their own platform and promised to nominate regulators who would unwind acquisitions like Facebook’s deal for WhatsApp and Instagram.
