A monopsony is a market situation in which there is only a single consumer of a good or service produced by many sellers. This unique market structure stands in contrast to other market forms such as monopoly, where there is only one producer, or competitive markets, where multiple producers and consumers interact freely.
Characteristics of a Monopsony
- Single Buyer: The defining feature of a monopsony is the presence of only one buyer in the market.
- Many Sellers: Unlike monopoly, the supply side features numerous sellers who depend on the single buyer for sales.
- Buyer Power: The single purchaser has significant power to influence prices and terms of purchase.
- Barriers to Entry and Exit: High barriers often exist for other potential buyers to enter the market or for sellers to withdraw, maintaining the monopsony condition.
Economic Implications
- Pricing Power: The monopsonist can leverage its purchasing power to dictate lower prices, which can lead to cost squeezes for producers.
- Market Efficiency: Monopsonies may lead to inefficiencies in allocation as prices and quantities are not determined purely by market forces.
- Wage Suppression: In labor markets, a monopsony might lead to lower wages, as employees have fewer alternative employers.
Examples of Monopsony
Labor Markets
One of the most cited examples of a monopsony is the labor market for certain professions or regions. For instance:
- Company Towns: In isolated or company-controlled towns, the firm controlling the town may be the only significant employer, creating a monopsonistic labor market.
- Healthcare Providers: In some regions, a single major employer may dominate hiring for healthcare professionals, such as nurses, thereby exerting monopsony power.
Government Procurement
- Defense Contracting: Governments often act as monopsonists in the market for defense equipment and technology, where specialized firms have few other buyers.
Historical Context and Applicability
Historical Evolution
The concept of monopsony was first formalized by economist Joan Robinson in her 1933 work, “The Economics of Imperfect Competition.” It was developed as a counterpart to monopoly, providing insights into labor market dynamics and capital investment strategies in the presence of significant buying power.
Modern Applications
Understanding monopsony is crucial in analyzing labor markets, assessing government procurement processes, and addressing market regulations aimed at preventing the misuse of buyer power.
Comparisons with Other Market Structures
Monopsony vs. Monopoly
- Participants: Monopsony has one buyer and many sellers, while monopoly has one seller and many buyers.
- Market Power: Both exhibit market power but in opposite positions of the market exchange (buying vs. selling).
Monopsony vs. Oligopsony
- Number of Buyers: An oligopsony has a few buyers instead of the single buyer in a monopsony.
- Market Influence: While both can influence market conditions, the degree of influence might be more distributed in an oligopsony compared to a concentrated monopsony.
Related Terms
- Oligopsony: A market with a few buyers controlling inputs.
- Monopoly: A market situation dominated by a single seller.
- Bilateral Monopoly: A market featuring a single buyer and a single seller besides many small buyers.

Summary
A monopsony represents a unique market situation characterized by a single buyer’s dominance over many sellers. This market structure has significant implications for pricing, market efficiency, and wage levels, highlighting the critical role of monopsony power in economic analysis and policy-making. Understanding monopsonies helps in analyzing labor markets, government procurement, and the mechanisms of market influence and control.
