Labor’s share of national income—that is, the amount of GDP paid out in wages, salaries, and benefits—has been declining in developed and, to a lesser extent, emerging economies since the 1980s. This has raised concerns about
slowing income growth, inequality, and loss of the consumer purchasing power that is needed to fuel demand in the economy. The decline has been much discussed and the rising power of companies vis-à-vis workers—whether from new technology, globalization, the hollowing out of labor unions, or
market consolidation—has shaped much of that discussion.
