The New York Times:
`Superstar firms' may have shrunk workers' share of income
8 March 2017
From manufacturing to retailing, giant companies have managed to gobble up a larger and larger share of the market. While such concentration has resulted in enormous profits for investors and owners of behemoths like Facebook, Google and Amazon, this type of “winner take most” competition may not be so good for workers as a whole. Over the last 30 years, their share of the total income kitty has been eroding. And the industries where concentration is the greatest is where labor’s share has dropped the most, according to research that analyzed confidential financial data from hundreds of companies. Think about the retail sector, where mom-and-pop stores once crowded the landscape. Now it is dominated by a handful of giants like Walmart, Target and Costco. “They’re very sophisticated and efficient and they don’t use as much labor,” said Mr. Autor, who worked on the research with a team of economists that included David Dorn, Lawrence F. Katz, Christina Patterson and John Van Reenen.
