Background
Monopsony power refers to the degree of control that a single buyer, or a small number of buyers, have over a market. This allows them to influence prices, terms, and availability of goods or services. The concept addresses situations where a market has a significant concentration on the buying side, usually analogous to ‘monopoly’ on the supply side.
Historical Context
The term ‘monopsony’ was first coined by economist Joan Robinson in her 1933 work “The Economics of Imperfect Competition.” Historically, it has been linked to labor markets, but its application has broadened to include various markets where few buyers dominate and thus shape market dynamics.
Definitions and Concepts
Monopsony Power: The influence or control a buyer (or group of buyers) can exert in a market. This is commonly measured by the level of industry concentration and market share held by these buyers.
Major Analytical Frameworks
Classical Economics
- Agrees with the concept but traditionally focuses on perfect competition and less so on market imperfections like monopsony.
Neoclassical Economics
- Analyses monopsony power through supply and demand models, particularly focusing on labor markets where employers can reduce wages below competitive levels.
Keynesian Economics
- Considers monopsony conditions in the discussions of wage rigidity and unemployment, integrating it into broader macroeconomic policies.
Marxian Economics
- Discusses monopsony in the context of labor exploitation and inequality, emphasizing the control of capital over labor.
Institutional Economics
- Examines the role of institutions and regulations in either curbing or enabling monopsony power.
Behavioral Economics
- Studies how cognitive biases and heuristics may affect both buyers and workers in monopsonistic conditions.
Post-Keynesian Economics
- Deals with monopsony in labor and product markets within broader discussions on economic inequality and market power dynamics.
Austrian Economics
- Critiques government intervention, arguing that monopsony is a natural market condition best regulated by market forces rather than policy.
Development Economics
- Focuses on labor markets in developing countries, where large employers often exert significant monopsony power, impacting wages and working conditions.
Monetarism
- Addresses monopsony within monetary contexts, particularly how central banking policies may unintentionally support large entities exerting monopsony power.
Comparative Analysis
Monopsony is often compared to monopoly. While both represent market power imbalances, monopsony focuses on the buying side, whereas monopoly focuses on the selling side. Analyzing these dynamics helps understand market outcomes in terms of prices, wages, and allocation of resources.
Case Studies
- Amazon in the publishing industry: As a dominant buyer, Amazon has significant power over the terms it sets with publishers.
- Walmart and suppliers: Walmart’s significant market share allows it to exert monopsony power for favorable purchasing terms from suppliers.
- Agricultural sector in developing countries: Large firms may exert control over prices paid to small-scale farmers.

Related Terms with Definitions
- Monopoly Power: The degree of control that a seller can exert over a market, often leading to higher prices and reduced availability of goods/services.
- Oligopsony: A market structure where a few buyers exert significant control over the market conditions, similar to oligopoly but on the buying side.
- Market Concentration: A measure of the degree to which a small number of firms represent a large proportion of the market.
By investigating monopsony power, economists gain insights into market structures and the impact of buying side imbalances on employment, pricing, and overall economic efficiency.
