Abstract
Since 1980, the world economy has experienced an increase of dominant firms. Dominant firms face limited competition in their market and exert monopoly power. Why has this happened, and why did it start in 1980? The rise of dominant firms has a direct impact on customers who pay higher prices, but it also has far-reaching implications for the macroeconomy. Widespread market power leads to wage stagnation and a decline in the labor share, it increases wage inequality, it slows down business dynamism, it reduces the number of startup firms and lowers innovation.
In this public paper Eeckhout reviews the determinants of the rise of dominant firms, discusses the causes and consequences, and proposes directions for policy solutions.
