If you owned two companies in the same industry, would you make them compete? Probably not, knowing the firms make higher profits if they don't.
Institutional investors such as BlackRock, Fidelity and Vanguard hold nearly 80 percent of the shares of public companies in the U.S. as they put 401(k)s and other private investments to work.
That's good for investors, but it might be bad for consumers and the economy as a whole, according to Martin Schmalz, assistant professor of finance at U-M's Ross School of Business. Natural competitors in many industries have nearly identical top shareholders, including Apple and Microsoft, CVS and Walgreens, and the largest three U.S. banks.
To determine if such common ownership has an effect on consumer prices, Schmalz and José Azar and Isabel Tecu of Charles River Associates, a Boston-based consulting firm, analyzed how airline ticket prices depend on who owns the airlines.
They found that prices on routes that become dominated by airlines with common shareholders are higher than when airlines are owned by different shareholders. On the average U.S. route, consumers pay 5 percent higher prices, and passenger volume is 6 percent lower than would be the case without common ownership.
"Antitrust law is focused on whether company A or company B merge," Schmalz said. "But when they have the same shareholders, it might not matter much because they're almost the same company anyway, just with a different name."
They're playing the consumer like a drum.
