That may mean lower pay for workers, and less innovation
COMPETITION forces companies to keep prices low to attract customers. But if a
few firms become powerful enough, they can see off competitors and charge more.
A new working paper by Jan De Loecker of the University of Leuven and Jan
Eeckhout of University College London presents evidence that this is happening
across the rich world.
The researchers examine markups selling prices divided by production costs. At
1, products are sold at cost; above 1, there is a gross profit. Using the
financial statements of 70,000 firms in 134 countries, the authors find average
markups rose from 1.1 in 1980 to 1.6 in 2016.
America and Europe saw the biggest increases (see chart). But in many emerging
markets markups barely rose. In China they fell. That suggests rich-world firms
may have been able to increase markups by outsourcing to cut labour costs.
Another possibility is that corporate concentration may have increased because
of lax antitrust enforcement or the growing heft of companies benefiting from
network effects, like internet firms.
Policymakers should take note. Greater market power for firms may also mean
less bargaining power for workers, and hence lower wages. A recent study by
David Autor of the Massachusetts Institute of Technology and four other
economists found that workers share of income in America has declined most
steeply in the most concentrated sectors.
A recent IMF working paper found that companies with relatively low markups
invested more when markups increased, whereas those that had started with high
markups invested less. This was particularly evident in highly concentrated
sectors. And the ratio of dividends to sales was higher for companies with
higher markups. Firms with greater market power, it seems, may not only have
higher profits but innovate less.
