Business and Economics

A "markup" is defined as the ratio of selling price to production costs. A markup of 1 for a firm means it is selling everything at cost. A new paper from Loecker and Eeckhout of University College London shows that corporate markups have been increasing steadily since the 1980's. There are obvious tax implications in that increased markups usually result from reduced competition that allows firms to raise prices.
From the article: "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."
