A Monopsony is a market structure characterized by a single buyer facing many sellers, in stark contrast to a monopoly, where only one seller exists. This unique market structure allows the monopsonist to exert significant influence over prices. Monopsonies are most commonly observed in labor markets, where a single employer may dominate employment in a specific area or industry. Still, they can also occur in markets for raw materials, components, and other goods and services where the buyer's power is concentrated, Monopsonies are particularly common in labor markets, when a single employer may control employment in a specific industry. However, they can arise in markets for raw materials, goods, and services where buyer power is concentrated.

The main feature of a monopsony is its ability to set prices. This power enables the monopsonist to purchase goods or services at lower prices than in a more competitive market. It leads to reduced seller income and potentially lower quality or quantity of goods and services.

While monopolies are known for causing inefficiencies by reducing output and raising prices, monopsonies create inefficiency by reducing the price paid to producers, which can lead to underproduction. This situation harms both producers and those who receive less for their goods or labor.

Understanding monopsony dynamics is crucial for analyzing labor markets, agricultural markets, and other sectors where buying power is concentrated.

A monopoly and a monopsony are both defined as a single entity that influences and distorts a free market. Still, both affect different sides of the market and operate in opposite ways. A monopoly exists when a single vendor controls or dominates the supply of products and services. In a monopsony, a single buyer controls or dominates the market for products and services. While monopolies create inefficiency by reducing output and raising prices, monopsonies reduce the price paid to sellers and lower the quantity transacted.

Monopsonies can have significant policy implications due to their power to suppress prices and reduce supply, leading to inefficiencies and inequities in the market. Governments may intervene in monopsonistic markets through minimum wage laws, collective bargaining rights, or anti-trust regulations to counteract the market power of the monopsonist.
