Do record corporate profits reflect rising market power rather than productivity?
Core argument: Summers argues that corporate profits near record highs may reflect increased market power rather than enhanced productivity, citing rising industry concentration, a major merger wave, and greater profit persistence among major companies.
Corporate profits are near record highs, which may indicate increased market power rather than enhanced productivity. This trend is supported by several factors: many industries have become more concentrated, a major merger wave has occurred, and there is evidence of greater profit persistence among major companies. Additionally, new business formation has declined, and overlapping ownership of competing companies has become more common. These developments suggest that monopoly power has increased, leading to higher profits, lower investment as firms restrict output, and lower interest rates due to reduced capital demand. This divergence between profit rates and the behavior of real interest rates and investment highlights the need for economists to focus on the implications of growing market power.
