Market Power Dynamics in Labor and Income Distribution

The distribution of income between labor and capital hinges critically on the degree of market power wielded by firms across product and labor markets. When firms attain greater pricing authority—whether through monopolistic control of product markets or monopsonistic influence over worker supply—they can suppress wage growth relative to output prices, leading to a declining labor share of national income. Technological change, firm concentration and global value chain integration have all been implicated in shifting surplus away from employees toward owners of capital and intangible assets. At the same time, the emergence of “superstar” enterprises, characterised by exceptional productivity and market reach, exacerbates wage dispersion by capturing a disproportionate share of profits. In many advanced and emerging economies, these dynamics interact with institutional settings—such as collective bargaining frameworks, competition policy and social safety nets—to shape outcomes for different skill groups, sectors and regions. Addressing imbalances in bargaining power therefore has both equity and efficiency implications, from promoting human capital accumulation to sustaining aggregate demand and social cohesion.

The graph below shows the total number of articles in market power dynamics in labor and income distribution across all publications each year (not limited to Nature Index journals).

Technical terms

Market power: The ability of a firm or group of firms to influence prices, output levels or wages in a market beyond competitive norms.

Labour share: The proportion of national income or value added allocated to employee compensation, including wages and benefits, as opposed to capital returns.

Monopsony power: A situation in which a buyer (often an employer) has sufficient control over a factor market—such as labour—to set wages below competitive equilibrium levels.

Global value chains: International production networks in which different stages of goods and services creation are located across multiple countries, affecting income distribution among participants.
